We've reached out to Spotify to inquire whether the service intends to add lagomorphs to the list.
A group of biologists led by Vilmos Altbäcker of Kaposvar University have persuaded these lagomorphs to add common milkweed to their diet.
The guinea pigs in their cage listen; they chew on their timothy hay, raise their heads; they worry about Hazel, though they are rodents and not lagomorphs.
This species was possibly a herbivore like other living lagomorphs.
It has preference for colonizing the dung of lagomorphs, such as hares and rabbits.
Sylvilagus obscurus is a part of the family Leporidae. This family consists of 12 genera, containing a total of 62 species of lagomorphs. Lagomorphs are characterized by 2 pairs of incisors. Sylvilagus species are herbivores but have been seen to practice coprophagy.
The testes are intra-abdominal outside the breeding season. During the breeding season they are found in folds of skin at the base of the penis (for all lagomorphs species, the testes are in front of the penis). Similar to other Lagomorphs, Hoffmann's pika does not have a baculum.
Female marsupials have paired uteri and cervices. Most eutherian (placental) mammal species have a single cervix and single, bipartite or bicornuate uterus. Lagomorphs, rodents, aardvarks and hyraxes have a duplex uterus and two cervices. Lagomorphs and rodents share many morphological characteristics and are grouped together in the clade Glires.
Simplicidentata is a group of mammals that includes the rodents (order Rodentia) and their closest extinct relatives. The term has historically been used as an alternative to Rodentia, contrasting the rodents (which have one pair of upper incisors) with their close relatives the lagomorphs (which have two).Landry, 1999, p. 286 However, Simplicidentata is now defined as including all members of Glires (the clade formed by lagomorphs and rodents) that share a more recent common ancestor with living rodents than with living lagomorphs.
It is likely that lagomorphs split off from the rest of the placental mammals around the Cretaceous-Palaeogene boundary.
Lagomorphs are similar to other mammals in that they all have hair, four limbs (i.e., they are tetrapods), and mammary glands and are endotherms. Lagomorphs possess a moderately fused postorbital process to the cranium, unlike other small mammals. They differ in that they have a mixture of "primitive" and "advanced" physical traits.
Despite the evolutionary relationship between lagomorphs and rodents, the two orders have some major differences. One of the ways in which lagomorphs differ from rodents is that the former have four incisors in the upper jaw (not two, as in the Rodentia). Also, lagomorphs are almost strictly herbivorous, unlike rodents, many of which will eat both meat and vegetable matter. They are similar to rodents in that their incisor teeth grow continuously throughout their lives, thus necessitating constant chewing on fibrous food to prevent the teeth from growing too long.
Gromov I.M. & Erbaeva M.A. (1995). The Mammals of Russia and adjacent territories. Lagomorphs and Rodents. St. Petersburg: ZIN RAN, 552 p.
Several groups of Notoungulates separately evolved ever growing teeth like rodents and lagomorphs, a distinction among ungulates only shared with Elasmotherium.
Other names used for this order, now considered synonymous, include: Duplicidentata - Illiger, 1811; Leporida - Averianov, 1999; Neolagomorpha - Averianov, 1999; Ochotonida - Averianov, 1999; and Palarodentia - Haeckel, 1895, Lilian, 2016. The evolutionary history of the lagomorphs is still not well understood. Until recently, it was generally agreed that Eurymylus, which lived in eastern Asia and dates back to the late Paleocene or early Eocene, was an ancestor of the lagomorphs. More recent examination of the fossil evidence suggests that the lagomorphs may have instead descended from Anagaloidea, also known as "mimotonids", while Eurymylus was more closely related to rodents (although not a direct ancestor).
Lagomorphs and rodents form the clade or grandorder Glires. Similarly to the rodents, bats, and some mammalian insectivores, they have a smooth-surfaced cerebrum.
Cuterebriasis is a parasitic disease affecting rodents, lagomorphs (hares, rabbits, pikas), felines, and canines. The etiologic agent is the larval development of botflies within the Cuterebra or Trypoderma genera, which occurs obligatorily in rodents and lagomorphs, respectively. Felines and canines serve as accidental hosts, but research suggests only by Trypoderma spp. Entrance into the body by first-instar larvae occurs via mucous membranes of natural orifices or open wounds as opposed to direct dermic penetration.
Euarchontoglires (synonymous with Supraprimates) is a clade and a superorder of mammals, the living members of which belong to one of the five following groups: rodents, lagomorphs, treeshrews, colugos and primates.
Taenia pisiformis, commonly called the rabbit tapeworm, is an endoparasitic tapeworm which causes infection in lagomorphs, rodents, and carnivores. Adult T. pisiformis typically occur within the small intestines of the definitive hosts, the carnivores. Lagomorphs, the intermediate hosts, are infected by fecal contamination of grasses and other food sources by the definitive hosts. The larval stage is often referred to as Cysticercus pisiformis and is found on the livers and peritoneal cavities of the intermediate hosts.
The smaller percentage of colonization in ruminants and horses may be due to competition with other types of cophriphilous fungi, who are not able to withstand the longer digestion times of lagomorphs.
Podospora setosa has been documented within many different countries including Canada, Germany, Spain, Brazil, Australia, the United Kingdom, and Ireland. These records indicate its presence in the excrement of rabbits, geese, farm animals, horses, and possums. The fungus itself favours the colonization of lagomorphs over ruminants, but surprisingly can be found on material passed by both types of digestion. This shows an ability to withstand digestion from several hours up to several days, as lagomorphs routinely ingest their own fecal matter.
In dry grassland areas all over the world different rodents and lagomorphs can be found. Rodents like voles (Microtes), such as the long-tailed vole, are found in North-America. The plateau pika (Ochotona curzoniae) is a keystone species in the Alpine meadows on the Tibetan plateau, which is an example of one of the rarer lagomorphs in dry grassland biomes. The burrows, which the plateau pika makes, are not only used by this species, but are also used by birds and lizards.
Shamolagus is an extinct genus of lagomorphs that lived in present-day China and Mongolia during the Eocene epoch. It contains two species, both of which are now extinct: Shamolagus grangeri and S. medius.
"Global completeness of the bat fossil record". Journal of Mammalian Evolution. 16: 151–173. doi:10.1007/s10914-009-9118-x. During this time ranids, lagomorphs and hyaenodonts disperse out of India, establishing their cosmopolitan ranges.
Skeleton of Alaskan Hare (Museum of Osteology) Like other herbivores, lagomorphs have to deal with a bulky diet in which the cell walls are composed of cellulose, a substance which mammalian digestive enzymes are unable to break down. Despite this, lagomorphs have developed a way of extracting maximum nourishment from their diet. First they bite off and shred plant tissues with their incisors and then they grind the material with their molars. Digestion continues in the stomach and small intestine where nutrients are absorbed.
Toxodon had broad jaws which were filled with bow shaped teeth and incisors. The teeth of Toxodon have no roots and are ever-growing (euhypsodont) like those of rodents and lagomorphs, and often exhibit enamel hypoplasia.
Collared pikas, like most other pikas, choose to live around rock slides to use the rocks as protection against the high temperatures they must endure throughout the day; they are referred to as cold-adapted lagomorphs.
The most diverse class of prey in the diet as known are mammals, with over 90 mammalian prey species reported. In the Cape Province, the cape hare (Lepus capensis) reportedly dominates the prey selection, comprising about 53% of the foods selected. Other lagomorphs, namely the slightly smaller Smith's red rock hare (Pronolagus rupestris), mildly larger African savanna hare (Lepus microtis) and the much larger scrub hare (Lepus saxatilis), are not infrequently taken both in and outside of the Cape area, but lagomorphs are not typically the main prey elsewhere.Cloudsley- Thompson, J.L. (1990).
The programme has reduced this population; only two individuals were caught in 2007.Ross, John (3 November 2007) "3,2,1 ... and then there were none". Edinburgh. The Scotsman. Of the lagomorphs only hares and rabbits are represented in Scotland.
Females are thought to have territories around . Mothers and daughters sometimes have greatly overlapping territories. Lynx are active during the evening and night and sleep during the day. The Lynx genus usually hunts lagomorphs, or hares and rabbits.
As with other lagomorphs, the tail is highly reduced, the jaw is perforated, and the soles of the feet are densely furred.Pekala, Susan. A Guide to Pocono Mammals for Educators. East Stroudburg University , 2004, Page 18. 1-114. Print.
This hare is one of the largest of the lagomorphs. Its head and body length can range from with a tail length of . The body mass is typically between . The hare's elongated ears range from from the notch to tip.
Masillamys sp. fossil from the Eocene Messel Pit fossil site, Germany Dentition is the key feature by which fossil rodents are recognized and the earliest record of such mammals comes from the Paleocene, shortly after the extinction of the non-avian dinosaurs some 66 million years ago. These fossils are found in Laurasia, the supercontinent composed of modern-day North America, Europe, and Asia. The divergence of Glires, a clade consisting of rodents and lagomorphs (rabbits, hares and pikas), from other placental mammals occurred within a few million years after the Cretaceous-Tertiary boundary; rodents and lagomorphs then radiated during the Cenozoic.
Some comparisons of the feeding ecology of four owls in north-central Colorado. The Southwestern Naturalist, 163-170. In central Utah, the lagomorphs (black- tailed jackrabbit/desert cottontail) and Ord's kangaroo rat each made up 39% of the food by number, respectively.
Leporipoxvirus is a genus of viruses, in the family Poxviridae, in the subfamily Chordopoxvirinae. Lagomorphs and squirrels serve as natural hosts. There are currently four species in this genus including the type species Myxoma virus. Diseases associated with this genus include: myxomatosis.
The Anagalidae and the Pseudictopidae probably represent a genuine clade. This clade is known as the Anagaloidea, which seems to be related to the rodents and lagomorphs after all. Together they form the clade Glires, often grouped with the Euarchonta to form the superorder Euarchontoglires.
Lagovirus is a genus of viruses, in the family Caliciviridae. Lagomorphs serve as natural hosts. There are currently only two species in this genus including the type species Rabbit hemorrhagic disease virus. Diseases associated with this genus include: necrotizing hepatitis leading to fatal hemorrhages.
One of these main prey type of import in the diets of common buzzards are leporids or lagomorphs, especially the European rabbit (Oryctolagus cuniculus) where it is found in numbers in a wild or feral state. In all dietary studies from Scotland, rabbits were highly important to the buzzard's diet. In southern Scotland, rabbits constituted 40.8% of remains at nests and 21.6% of pellet contents, while lagomorphs (mainly rabbits but also some young hares) were present in 99% of remains in Moray, Scotland. The nutritional richness relative to the commonest prey elsewhere, such as voles, might account for the high productivity of buzzards here.
Remarkably, the capture of syncytin or syncytin-like genes has occurred independently, from different groups of endogenous retroviruses, in diverse mammalian lineages. Distinct, syncytin-like genes have been identified in primates, rodents, lagomorphs, carnivores, and ungulates, with integration dates ranging from 10 to 85 million years ago.
The gray fox is an omnivorous, solitary hunter. It frequently preys on the eastern cottontail (Sylvilagus floridanus) in the eastern U.S., though it will readily catch voles, shrews, and birds. In California, the gray fox primarily eats rodents, followed by lagomorphs, e.g. jackrabbit, brush rabbit, etc.
Micro-livestock is the term used for much smaller animals, usually mammals. The two predominate categories are rodents and lagomorphs (rabbits). Even smaller animals are kept and raised, such as crickets and honey bees. Micro-livestock does not generally include fish (aquaculture) or chickens (poultry farming).
Birds are sometimes taken, including tired petrels around Juan Fernández Islands. Other prey include other rodents & lagomorphs, frogs, lizards, snakes, and fish. The variable hawk hunts with prey being spotted while soaring from the air and pinned on the ground. Breeding is at various seasons and may be variable for all races.
Anagale is an extinct genus of mammal from the early Oligocene of Mongolia. Its closest living relatives are the rodents and lagomorphs. Anagale was 30 cm (1 ft) long and resembled a rabbit, but with a longer tail. Also, the build of its hind legs indicates that it walked, and did not hop.
A Chinchilla Rabbit eating a leaf during the fall. Chinchilla rabbits are a group of three rabbit breeds that have been bred for a coat that resembles that of chinchillas. Despite their name, they are not related to and cannot interbreed with chinchillas, which are a species of rodent. Rabbits are lagomorphs.
A 2005 study of the then remnant population surviving on Mount Lassen found that the foxes are nocturnal hunters whose diet is predominantly mammals, especially rodents and mule deer, supplemented by birds, insects and pinemat manzanita berries as seasonally available. Lagomorphs (hares, rabbits and pikas) were virtually absent from the foxes' diet.

J. Raptor Res., 26(4), 235–238. Mammalian prey for common buzzards other than rodents, insectivores and lagomorphs is rarely taken. Occasionally, some weasels (including polecats) and perhaps martens might be attacked by buzzards, more likely the more powerful female buzzard since such prey is potentially dangerous and of similar size to a buzzard itself.
In comparison, the lightest mean prey mass in dietary studies of the great horned owl was while the highest was .Donázar, J. A., Travaini, A., Ceballos, O., Delibes, M., & Hiraldo, F. (1997). Food habits of the great horned owl in northwestern Argentine Patagonia: the role of introduced lagomorphs. Journal of Raptor Research, 31(4), 364-369.
Dermacentor is a genus of ticks in the family Ixodidae, the hard ticks. The genus has a cosmopolitan distribution, with native species on all continents except Australia. Most occur in the Nearctic realm. Hosts of Dermacentor ticks include many large and small mammals, including horses, deer, cattle, lagomorphs, peccaries, porcupines, tapirs, desert bighorn sheep, and humans.
Notoedric mange, also referred to as Feline scabies, is a highly contagious skin infestation caused by an ectoparasitic and skin burrowing mite Notoedres cati (Acarina, Sarcoptidae). N. cati is primarily a parasite of felids, but it can also infest rodents, lagomorphs, and occasionally also dogs and foxes. This skin disease also has zoonotic potential.“Notoedres.” The Merriam- Webster.
Rabbits and hares (lagomorphs) were once considered rodents, but are distinguished by having six—one small pair, called "peg teeth", is located directly behind the most anterior pair. Incisors are used to bite off tough foods, such as red meat. Cattle (cows, bulls, etc.) have none on top but a total of six on the bottom.
The order Lagomorpha includes rabbits, hares, and pikas. There are few lagomorphs in the Caribbean, and they are either introduced or restricted to islands close to the mainland. The European hare (Lepus europaeus) has been introduced to Barbados.Smith and Johnston, 2008 The eastern cottontail (Sylvilagus floridanus) occurs near Venezuela on Aruba, Curaçao, Margarita, and the Islas de los Testigos.
Among Glires, the group containing rodents, lagomorphs, and their primitive relatives, the absence of HSB from the incisors has been considered primitive.Martin, 2004, p. 411 Some early representatives, including Eurymylus, lack HSB, but others, including MatutiniaMartin, 2004, p. 417 and some mimotonids, have double-layered incisor enamel with HSB in the inner portion (portio interna, PI).
Mammal species differ between the various ecoregions of Saskatchewan. Members of six orders of placental mammals which inhabit Saskatchewan. They are the bats, carnivores (including the pinnipeds), artiodactyls, cetaceans, insectivores, and rodents (including the lagomorphs). Barren-ground caribou (Rangifer tarandus groenlandicus) There are fewer varieties of species as elevation increases which corresponds to the Taiga and Boreal Shield and Cypress Hills Uplands econzones.
The ears are moderately large and suborbicular, and are hairy on both surfaces, normally dark with white margins. The pika's "buried" tail is longer relative to body size compared to other lagomorphs. It has a slightly rounded skull with a broad and flat preorbital region. The fur color of the pika is the same for both sexes, but varies by subspecies and season.
Zalambdaltestids were insectivores, having zalambdodont molars much as various modern insectivorous species. They are uniquely suited to a saltitorial, cursorial lifestyle, bearing long, semi- digitigrade limbs and a spinal column similar to that of modern lagomorphs. Like most non-placental mammals, the presence of epipubic bones probably meant that they gave birth to poorly developed young much like modern marsupials and monotremes.
Mesotheriids were small to medium-sized notoungulates; larger forms were approximately the size of a sheep (Shockey et al., 2007). Additionally, the family is characterized by specializations of the teeth and skeleton. In the dentition, all mesotheriids have ever-growing incisors with enamel restricted to the anterior surface, a condition termed gliriform, as it also occurs in Glires (rodents and lagomorphs).
Rabbits and other lagomorphs usually shed their deciduous teeth before (or very shortly after) their birth, and are usually born with their permanent teeth.Dental Anatomy & Care for Rabbits and Rodents The teeth of rabbits complement their diet, which consist of a wide range of vegetation. Since many of the foods are abrasive enough to cause attrition, rabbit teeth grow continuously throughout life.Brown, Susan.
The dependence on lagomorphs also extends into Mexico, as in Baja California about a quarter of identified prey was black-tailed jackrabbit and either desert or the larger Mexican cottontail (Sylvilagus cunicularius).Llinas-Gutirrez, J., Arnaud, G. & Acevedo, M. (1991). Food habits of the Great Horned Owl in the Cape Region of Lower California, Mexico. Journal of Raptor Research, 25 (4): 140-141.
The European beaver was hunted almost to extinction, but is now being re-introduced throughout the continent. The three European lagomorphs are the European rabbit, mountain hare and European hare. Roe deer, a common European ungulate Widespread and locally common ungulates are boar, moose, roe deer, red deer, reindeer, wisent, chamois and argali. Today the larger carnivores (wolves and bears) are endangered.

Examples include tapirs, manatees, and many rodents. When two lophs form transverse, often ring-shaped, ridges on a tooth, the arrangement is called bilophodont. This pattern is common in primates, but can also be found in lagomorphs (hares, rabbits, and pikas) and some rodents. Extreme forms of lophodonty in elephants and some rodents (such as Otomys) is known as loxodonty.
Mountain hare The lagomorphs comprise two families, Leporidae (hares and rabbits), and Ochotonidae (pikas). Though they can resemble rodents, and were classified as a superfamily in that order until the early 20th century, they have since been considered a separate order. They differ from rodents in a number of physical characteristics, such as having four incisors in the upper jaw rather than two.
Their hind feet are long, which is thought to allow them to move easily in snowy conditions. It has been reported that they also use their feet for defense against predators. This species weighs from , averaging , and it is thus one of the largest lagomorphs, alongside the similarly sized brown hare and Arctic hare. The Alaskan hare's ears are fairly short compared to most.
As a carnivore it preys on small terrestrial mammals such as rodents, lagomorphs, armadillos, opossums, and also fish, insects, reptiles and small birds. It usually feeds on the kill immediately, but removes bird feathers before. It typically preys on animals that weigh less than , but rarely targets large animals such as deer and peccaries. An ocelot requires of food every day to satisfy its energy requirements.
Volumes I and II (No. 3rd edition). Johns Hopkins University Press. Numerous other small mammals may also be occasionally taken including several species each of hedgehogs, shrews and moles, beyond the common hare, at least 7 other species of lagomorphs, about a dozen species each of murid rodents and cricetid rodents (especially hamsters and voles), 5 species of zokor and assorted dormice and jerboas.
Lagomorphs are widespread around the world and inhabit every continent except Antarctica. However, they are not found in most of the southern cone of South America, in the West Indies, Indonesia or Madagascar, nor on many islands. Although they are not native to Australia, humans have introduced them there and they have successfully colonized many parts of the country and caused disruption to native species.
Many species of lagomorphs, particularly the rabbits and the pikas, are gregarious and live in colonies, whereas hares are generally solitary species, although many hares travel and forage in groups of two, three, or four. The rabbits and pikas rely on their holes as places of safety when danger threatens, but hares rely on their long legs, great speed and jinking gait to escape from predators.
With a skull adapted for carnivory, Lutrine opossums are carnivorous and insectivorous feeding on small rodents and lagomorphs, birds, insects, small crustaceans. They are considered to be the most carnivorous of all the members of the order Didelphimorphia. There is video footage of lutrine opossums preying on venomous snakes. Captive populations have been observed eating butterfish mixed with meat, frogs, earthworms, shrimp and mice.
On Ibiza a strange ecosystem without terrestrial mammals developed in which birds and bats were the main vertebrates, while in Menorca a giant rabbit evolved that covered the same niche as Myotragus in Majorca. With the level of the sea falling in the glacial era, Majorca and Menorca were united and Myotragus replaced the great Menorcan lagomorphs. Both islands separated again at the beginning of the Holocene.
Due to seasonality and changes in moisture conditions of their habitat, cottontails adjust their diets based on many influential factors that impact the seasonal changes of vegetation (i.e. moisture content, abundance, nutrition value, etc.). Like most lagomorphs, it is coprophagic, re-ingesting and chewing its own feces to extract the nutrients as effectively as possible. The desert cottontail, like all cottontails, eats on all fours.
In populations with sexual dimorphism, males are slightly larger than females. The American pika is intermediate in size among pikas. The hind legs of the pika do not seem to be much longer than its front legs and its hind feet are relatively short when compared to most other lagomorphs. It has densely furred soles on its feet except for black pads at the ends of the toes.
This species is said to be endemic and is native to the Barisan Mountains in Sumatra, Indonesia in north-west Sumatra. It has also been found in west and southwest Sumatra, and there is one record from Gunung Leuser National Park. It lives in forests at altitudes of 600–1600 metres above sea level. It is one of the few lagomorphs that chooses to live in the dense rainforest.
Large mammal species currently found in Illinois include whitetail deer and coyote, with the latter becoming urbanized in the Chicago area, as well as common in the rural areas. Furbearers commonly found include opossum, raccoon, mink, red and gray foxes, and muskrat. Commonly seen lagomorphs include the cottontail rabbit and commonly seen rodents include squirrels. Game birds found include Canada goose, mallard duck, ruffed grouse, wild turkey, and bobwhite quail.
Restoration Its eyes were not directed towards the sides, as are those of nearly all the herbivorous mammals, but towards the front like nearly all primates and carnivorans, granting them stereoscopic vision. The lower jaw contained two perennial-growth incisors, like rodents and lagomorphs, but not other ungulates. The lower jaw usually lacked other incisors, though some jaws have been found with vestigial second incisors. The upper jaw lacked incisors.
Newborn cottontails are particularly vulnerable to these attacks. Cottontails use burrows vacated by other animals, and the burrows are used for long enough periods that predators can learn where the cottontails reside and repeatedly return to predate the lagomorphs. Though cottontails are prolific animals that can have multiple litters in a year, few of the resulting offspring survive to adulthood. Those that do grow very quickly and are full grown adults at three months.
Swamp rabbits are herbivorous; they eat a variety of foraged plants, including grasses, sedges, shrubs, tree bark seedlings, and twigs. They feed mainly at night but rain showers will often cause them to feed during daytime as well. A study has found that the preferred foods of S. aquaticus are savannah panicgrass (Phanopyrum gymnocarpon), false nettle (Boehmeria cylindrica), dewberry (Rubus trivialis) and greenbrier (Smilax bona-nox). Like other lagomorphs, they have a double digestion.
Larger animals may regard guinea pigs as prey, though some (such as dogs or cats) can be trained to accept them. Opinion is divided over the cohousing of guinea pigs and domestic rabbits. Some published sources say that guinea pigs and rabbits complement each other well when sharing a cage. However, rabbits have different nutritional requirements; as lagomorphs, they synthesize their own Vitamin C, so the two species will not thrive if fed the same food when housed together.
It preys on small terrestrial mammals, such as armadillo, opossum and lagomorphs. Both sexes become sexually mature at around two years of age; they can breed throughout the year, though the peak mating season varies geographically. After a gestation period of two to three months, the female gives birth to a litter of one to three kittens. They stay with their mother for up to two years, after which they leave to establish their own territories.
Glires (Latin glīrēs, dormice) is a clade (sometimes ranked as a grandorder) consisting of rodents and lagomorphs (rabbits, hares, and pikas). The hypothesis that these form a monophyletic group has been long debated based on morphological evidence. Two morphological studies, published in 2001 and 2003, strongly support the monophyly of Glires. In particular, the 2003 study reported the discovery of fossil material of basal members of Glires, particularly the genera Mimotona, Gomphos, Heomys, Matutinia, Rhombomylus, and Sinomylus.
The lifespan of a cottontail averages about two years, depending on the location. Almost every living carnivorous creature comparable to or larger in size than these lagomorphs is a potential predator, including such diverse creatures as domestic dogs, cats, humans, snakes, coyotes, mountain lions, foxes, and if the cottontail is showing signs of illness, even squirrels. The cottontail's most frequent predators are various birds of prey. Cottontails can also be parasitized by botfly species including Cuterebra fontinella.
What distinguishes the digestive system of the common ringtail possum from that of the koala and the greater glider is the caecal content transfers directly back to the stomach. Because of this, the ringtail possum is able to gain more protein. This is also done by lagomorphs like rabbits and pikas. Hard faeces are produced during the night while feeding and are not eaten, while soft faeces are produced during the day during rests and are eaten.
Juvenile eating a squirrel The red-tailed hawk is carnivorous, and a highly opportunistic feeder. It is said that nearly any small animal they encounter may be viewed as potential food. Their most common prey are small mammals such as rodents and lagomorphs, but they will also consume birds, reptiles, fish, amphibians and invertebrates. Prey varies considerably with regional and seasonal availability, but usually centers on rodents, accounting for up to 85% of a hawk's diet.
Wood rat (Neotoma lepida) nest at Joshua Tree National Park In rodents and lagomorphs, the nesting instinct is typically characterized by the urge to seek the lowest sheltered spot available; this is where these mammals give birth. Rats, for example, prefer to burrow amongst dense areas of vegetation or around human settlements which they come into contact with often. Often some rodent species create burrows that develop microclimates. This is another way that nesting instinct aids in thermoregulation.
Podospora appendiculata is a coprophilous fungus that is most commonly found in the dung of lagomorphs, such as hares and rabbits, in temperate to warm climates. A member of the division Ascomycota, P. appendiculata is characterized by ovoid, hair-studded perithecia which can bear a distinctive violaceous colouring and peridia which are coriaceous, or leathery, in texture. Podospora appendiculata has been shown to produce three compounds (Appenolide A, Appenolide B,and Appenolide C) with antimicrobial properties.
Integrative zoology, 10(2), 216-226. Other mammals, outside of aforementioned groups (i.e. cricetid, murid and geomyoid) rodents, are known to be hunted but are generally a negligible part of the long-eared owl's diet, including hedgehogs, moles, rabbits and hares and weasels as well as rarely taken rodents like dormice, flying squirrels and squirrels (including chipmunks). While lagomorphs such as hares and rabbits are very rare prey for long-eared owls, occasionally they may capture one.
It is possible that in both Altai and Transbaikal that the shifts to differing reported primary prey species are responses of the eagles to shifting prey availabilities as many burrowing mammals are subject to population cycles as well as human-sourced depletions. While rodents and some lagomorphs are usually favored in the diet, in some areas steppe eagles can live at least in part off of quite different prey such as long-eared hedgehogs (Hemiechinus auritus).Berezovikov, N.N. & Anisimov, E.I. (2009).
Their description, in 2005, helped to bridge the gap between more typical rodents and lagomorphs. Data published in 2001, based on nuclear DNA, supported Glires as a sister of Euarchonta to form Euarchontoglires, but some genetic data from both nuclear and mitochondrial DNA have been less supportive. A study, published in 2007, investigating retrotransposon presence/absence data unambiguously supports the Glires hypothesis. Studies published in 2011 and 2015 place Scandentia as a sister clade of the Glires, invalidating Euarchonta as a clade.
Many lagomorphs breed several times a year and produce large litters. This is particularly the case in species that breed in underground, protective environments such as burrows. The altricial young of rabbits, called kittens, are born naked and helpless after a short gestation period and the mother can become pregnant again almost immediately after giving birth. The mothers are able to leave these young safely and go off to feed, returning at intervals to feed them with their unusually rich milk.
The leporids first appeared in the late Eocene and rapidly spread throughout the Northern Hemisphere; they show a trend towards increasingly long hind limbs as the modern leaping gait developed. The pikas appeared somewhat later in the Oligocene of eastern Asia. Lagomorphs were certainly more diverse in the past than in the present, with around 75 genera and over 230 species represented in the fossil record and many more species in a single biome. This is evidence that lagomorph lineages are declining.
To find these similarities, a genome sequence analysis was completed. One theory of how the European Eyach virus is proposed to have come about in Europe is by the migration of lagomorphs from North America over fifty million years ago. Since then, the virus took on some differences, and is now considered its own species of virus. European Eyach virus was isolated in 1976 from Ixodes ricinus ticks in Europe and in 1981 from the same species along with Ixodes ventalloi in 1981.
Historically, up to 30 subspecies of European hare have been described, although their status has been disputed. These subspecies have been distinguished by differences in pelage colouration, body size, external body measurements, skull morphology and tooth shape. Sixteen subspecies are listed in the IUCN red book, following Hoffmann and Smith (2005): Twenty-nine subspecies of "very variable status" are listed by Chapman and Flux in their book on lagomorphs, including the subspecies above (with the exceptions of L. e. connori, L. e.
Richard Owen, 1856 In 1758, in his seminal work Systema Naturae, Linnaeus (1707–1778) classified horses (Equus) together with hippos (Hippopotamus). At that time, this category also included the tapirs (Tapirus), more precisely the lowland or South American tapir (Tapirus terrestus), the only tapir then known in Europe. Linnaeus classified this tapir as Hippopotamus terrestris and put both genera in the group of the Belluae ("beasts"). He combined the rhinos with the Glires, a group now consisting of the lagomorphs and rodents.
In some urban areas, infestations of feral European rabbits (descended from pets) have become a problem. Helsinki, for example, host to one of the northernmost populations of the species, had an estimated 2,500 European rabbits at the end of 2006, doubling to 5,000 by autumn 2007. In Iceland, populations of O. cuniculus are found in urban Reykjavik as well as in the Vestmannaeyjar archipelago. In Finland, the introduced European rabbit vies with the native lagomorphs: the European hare and the mountain hare.
Least chipmunks are found through the western United States from northern New Mexico and western North and South Dakota to eastern California, Oregon and Washington, and throughout much of southern and western Canada from Yukon and southeastern British Columbia Nagorsen, D.W. (2005). "Rodents and Lagomorphs of British Columbia". Royal BC Museum, Victoria, BC to Ontario, and into the Upper Peninsula of Michigan and neighboring parts of Wisconsin and Minnesota. Throughout this range, as many as 21 subspecies have been identified.
According to the traditional (morphological) view, Anagaloidea is part of the superorder Anagalida, along with the elephant shrews, rodents and lagomorphs. However, the Anagalida are considered to be polyphyletic. Genetic studies have shown that the elephant shrews are actually part of a different macro-group of mammals called the Afrotheria, while the position of several extinct families of Anagalida is uncertain. The Zalambdalestidae are almost certainly unrelated to any of these groups; they probably represent more basal Eutherians and might not even be true Eutherians at all.
As its preferred habitat seldom overlaps with larger eagles such as golden eagles and white-tailed eagles, the eastern imperial eagle is usually the top avian predator in its breeding grounds. In particular, smaller raptors with largely overlapping diets (i.e. ground squirrels, hamsters, voles & lagomorphs) and habitat preferences such as saker falcons (Falco cherrug) and long-legged buzzards (Buteo rufinus) are often at a disadvantage in direct competition with the eagle species.Bagyura, J., Szitta, T., Haraszthy, L., Viszló, L., Fidlóczky, J., & Prommer, M. (2012).
Fossil occurrences of leporids and ochotonids and global environmental change (climate change, C3/C4 plants distribution). The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae (hares and rabbits) and the Ochotonidae (pikas). The name of the order is derived from the Ancient Greek lagos (λαγώς, "hare") + morphē (μορφή, "form"). There are ninety-one extant species of lagomorph, including thirty species of pika, twenty-nine species of rabbit and cottontail, and thirty-two species of hare.
Mice are mammals of the clade (a group consisting of an ancestor and all its descendants) Euarchontoglires, which means they are amongst the closest non- primate relatives of humans along with lagomorphs, treeshrews, and flying lemurs. Laboratory mice are the same species as the house mouse, however, they are often very different in behaviour and physiology. There are hundreds of established inbred, outbred, and transgenic strains. A strain, in reference to rodents, is a group in which all members are as nearly as possible genetically identical.

Large‐scale spatio‐temporal shifts in the diet of a predator mediated by an emerging infectious disease of its main prey. Journal of Biogeography, 36(8), 1502-1515. In additional, significant numbers of other lagomorphs may be taken, extending to occasional Granada hares (Lepus granatensis) as well as accounts of Bonelli's eagles hunting European hares (Lepus europaeus) in the Greek isles and Indian hares (Lepus nigricollis) in the lower Himalayas.
The most commonly infected terrestrial animals in the U.S.A. are raccoons, skunks, foxes, and coyotes. Any bites by such wild animals must be considered a possible exposure to the rabies virus. Most cases of rabies in rodents reported to the Centers for Disease Control and Prevention in the U.S. have been found among groundhogs (woodchucks). Small rodents such as squirrels, hamsters, guinea pigs, gerbils, chipmunks, rats, mice, and lagomorphs like rabbits and hares are almost never found to be infected with rabies, and are not known to transmit rabies to humans.

Most guinea pigs have fur, but one laboratory breed adopted by some pet owners, the skinny pig, is a mostly furless breed. Some breeds are longfur breeds such as the Peruvian, the Silkie, and the Texel. In the 1990s, a minority scientific opinion emerged proposing that caviomorphs, such as guinea pigs, chinchillas, and degus, are not rodents and should be reclassified as a separate order of mammals (similar to lagomorphs). Subsequent research using wider sampling restored the consensus among mammalian biologists regarding the current classification of rodents as monophyletic.
In 1891 Santiago Ramón y Cajal described slender horizontal bipolar cells he had found in an histological preparation of the developing marginal zone of lagomorphs. These cells were then considered by Gustaf Retzius as homologous to the ones he had found in the marginal zone of human fetuses around mid-gestation in 1893 and 1894. He described those cells as having large, horizontal, sometimes vertically orientated somata located at some distance from the pia. Later on in 1899, Cajal drew the neurons in layer I of the human fetus at term and newborn.
Snow camouflage is the use of a coloration or pattern for effective camouflage in winter, often combined with a different summer camouflage. Summer patterns are typically disruptively patterned combinations of shades of browns and greys, up to black, while winter patterns are dominated by white to match snowy landscapes. Among animals, variable snow camouflage is a type of seasonal polyphenism with a distinct winter plumage or pelage. It is found in birds such as the rock ptarmigan, lagomorphs such as the Arctic hare, mustelids such as the stoat, and one canid, the Arctic fox.
The Lepi are a rabbit-like species that stand on two legs. This was the Basic name used to describe the Lepus carnivorus, a species of tall, furred lagomorphs which was native to the planet Coachelle Prime. The Lepi were a carnivorous race, distinguished by their large incisors and the various colours of their fur, which ranged from green to dark blue. Despite their appearance, the Lepi were a technologically advanced race, having achieved spaceflight and colonized the five planets in the system and the neighbouring asteroid belt.

JHU Press. 3.2% of 7077 prey items from across the range for barred owls were rabbits or hares. As for the often sympatric eastern cottontail, juveniles were exclusively taken in summer in Wisconsin but presumably fully- grown ones were taken in large numbers during winter in Illinois, where they were the third most recorded prey species at 14.4% of the balance.
As biodiversity outside the limits of the protected areas is equally important, proposals have been mooted to promote this activity. The Regions of Chile. Laws regulating exploitation of wildlife are in force since 1888 which have been improved upon since the 1990s, with regulations of 1993 being the most recent and stringent. This has resulted in almost total check over hunting and commercialization of vertebrates, except for exploitation of bird species, two deer (introduced), vertebrate pests, and the inducted lagomorphs species of European hare (Lepus timidus) and European rabbit (Oryctolagus cuniculus).
Coprophagy refers to many kinds of feces- eating, including eating feces of other species (heterospecifics), of other individuals (allocoprophagy), or one's own (autocoprophagy) – those once deposited or taken directly from the anus. In humans, coprophagia has been described since the late 19th century in individuals with mental illnesses and in unconventional sexual acts. Some animal species eat feces as a normal behavior, in particular lagomorphs, which do so to allow tough plant materials to be digested more thoroughly by passing twice through the digestive tract. Other species may eat feces under certain conditions.
The area postrema is located in the caudal medulla oblongata near the junction of the brainstem and the spinal cord. In humans and in most other mammals that have been studied, it consists of swellings on either wall of the fourth ventricle. In rodents and lagomorphs, however, the area postrema forms a midline structure dorsal to the obex. When viewed histologically for its capillary distribution and morphology, the area postrema has numerous subregions separated according to capillary permeability, rates of blood flow, and duration of blood transit through respective capillary beds.
North of the beach of Macinaggio at Point Coscia is a partially collapsed, wave-cut grotto, La Grotte de la Coscia, containing dateable sedimentary layers. In one deposit of the Last glacial period, a tumulus of crania and antlers of Cervus cazioti and various lagomorphs, rodents and other remains have been found with pebbles that could be interpreted as flakes and cores, fireplace sites and an ovate structure; that is, the most likely interpretation is that this is a site of the Middle Paleolithic, the first evidence of Early Stone Age occupation.
Two lagomorphs are present, the eastern cottontail (Sylvilagus floridanus), and the black-tailed jackrabbit (Lepus californicus). Other mammals include the dog-like coyote, as well as the much smaller prairie dog and a species of badger. Nine snake species are found in this arid environment, the plains hog-nosed snake, western coachwhip, bullsnake, longnose snake, plains blackhead snake, blackneck garter snake, plains garter snake, lined snake, and prairie rattlesnake. The broad-headed skink, prairie racerunner, red-lipped plateau lizard, northern earless lizard, eastern collared lizard, and Texas horned lizard are also indigenous to the area.
For example, clutch sizes were twice as large on average where rabbits were common (Moray) than were where they were rare (Glen Urquhart).Swan, G. (2011). Spatial variation in the breeding success of the common buzzard Buteo buteo in relation to habitat type and diet (Doctoral dissertation, Department of Life Sciences, Silwood Park, Imperial College London). In northern Ireland, an area of interest because it is devoid of any native vole species, rabbits were again the main prey. Here, lagomorphs constituted 22.5% of prey items by number and 43.7% by biomass.
In many other areas, ground squirrels are secondary prey, usually ranking after lagomorphs in dietary significance. This is especially true in the contiguous Western United States outside of Washington state and coastal California where they often register as second, third or even fourth most represented family by remains. Prairie dogs feature only as supplemental prey for breeding golden eagles but wintering eagles reportedly prey heavily on colonies of black-tailed prairie dogs (Cynomys ludovicianus).Weber, D.A. Winter raptor use of prairie dog towns in the Denver, Colorado vicinity.
J. Winkler, Neogene paleobiogeography and East African paleoenvironments: contributions from the Tugen Hills rodents and lagomorphs. Journal of Human Evolution, Vol 42, January 2002 During the early Tertiary, Africa was covered by a vast evergreen forest inhabited by an endemic forest fauna with many types common to southern Asia. In the Pliocene the climate became dry and most of the forest was destroyed, the forest animals taking refuge in the remaining forest islands. At the same time a broad land-bridge connected Africa with Asia and there was a great invasion of animals of the steppe fauna into Africa.
Molecular phylogenetic studies have suggested that the treeshrews should be given the same rank (order) as the primates and, with the primates and the flying lemurs (colugos), belong to the grandorder Euarchonta. According to this classification, the Euarchonta are sister to the Glires (lagomorphs and rodents), and the two groups are combined into the superorder Euarchontoglires. However, the alternative placement of treeshrews as sister to both Glires and Primatomorpha cannot be ruled out. Recent studies place Scandentia as sister of the Glires, invalidating Euarchonta: It is this organization that is shown in the tree diagram below.
Most animals can be infected by the virus and can transmit the disease to humans. Infected bats, monkeys, raccoons, foxes, skunks, cattle, wolves, coyotes, dogs, cats, and mongooses (normally either the small Asian mongoose or the yellow mongoose) present the greatest risk to humans. Rabies may also spread through exposure to infected bears, domestic farm animals, groundhogs, weasels, and other wild carnivorans. However, lagomorphs, such as hares and rabbits, and small rodents such as chipmunks, gerbils, guinea pigs, hamsters, mice, rats, and squirrels, are almost never found to be infected with rabies and are not known to transmit rabies to humans.
Stoat surplus killing a family of chipmunks, as illustrated by Ernest Thompson Seton As with the least weasel, mouse-like rodents predominate in the stoat's diet. However, unlike the least weasel, which almost exclusively feeds on small voles, the stoat regularly preys on larger rodent and lagomorph species, and will take down individuals far larger than itself. In Russia, its prey includes rodents and lagomorphs such as European water voles, common hamsters, pikas, and others, which it overpowers in their burrows. Prey species of secondary importance include small birds, fish, and shrews and, more rarely, amphibians, lizards, and insects.
Gomphos is an extinct genus of early lagomorph from the early Eocene of the China and Mongolia. Gomphos was first named in 1975 from material found in the Gashato Formation. There are currently two species in this genus: G. elkema, from the Greek word γόμφος (Romanized gomphos), which means "peg", but can also be used to signify molar teeth; and G. shevyrevae was named later in honour of the lead author who named the first original genus and species of Gomphos elkema. Analysis supports Gomphos as one of the earliest lagomorphs, the group that includes rabbits, hares and pikas.
The mountain cottontail dominates the biomass of prey in the Sierran foothills of California, making up 61.1% of the biomass, although are numerically secondary to desert woodrat. Remarkably, in the Morley Nelson Snake River Birds of Prey National Conservation Area of Idaho, individual rodents (1159 counted) were more than 10 times more numerous than lagomorphs (114 counted) by quantity and yet the jackrabbit and mountain cottontail still made up approximately half of the biomass.Marti, C. D., & Kochert, M. N. (1996). Diet and Trophic Characteristics of Great Horned Owls in Southwestern Idaho. Journal of Field Ornithology, 499-506.
Podospora appendiculata is a coprophilous fungus that grows on the dung of many herbivorous animals but is most strongly associated with the dung of lagomorphs, a group which includes hares and rabbits. While it has been recovered from the dung of horses and cows, Podospora appendiculata tends only to appear in excrement found in forests. In more domesticated settings, such as pastures as fields, P. appendiculata is considerably more scarce. The fungus grows widely in temperate to warm climates, and has been identified naturally in New Zealand, Israel, Japan, Brazil, and in areas throughout North America and Europe.
Because of the variety in environment that surrounds Rudd Creek Pueblo, a wide array of faunal remains were recovered, however, only the juniper savanna and montane forest were represented in the assemblage. In total, 906 specimens, representing 17 different taxa, were found including lagomorphs (rabbits and hares) and rodents. Only 14% of the faunal assemblage was made up of large- game specimens, the majority including deer and pronghorn antelope.Clark, Tiffany C. 2006 Rudd Creek Pueblo: A Late Tularosa Phase Village in East Central Arizona. Kiva 71(4):416Clark, Tiffany C. 2006 Rudd Creek Pueblo: A Late Tularosa Phase Village in East Central Arizona.
Dawson's research has focused on the evolution of mammals, especially of Cenozoic rodents and lagomorphs. She has also maintained an active research program at Ellesmere Island and other sites in the high arctic which showed that tropical and subtropical animals lived inside the Arctic Circle during the exceptionally warm climates of the Paleogene geological period. Through this work, she and her collaborators discovered the first fossils of Tertiary land animals that documented a migration route between North America and Europe. This migration route provided early support for the theory of plate tectonics, which was only gaining wide acceptance in the 1960s and 1970s.
Black-tailed jackrabbits are an important food source for western great horned owls. Although generally no match for rodents in sheer quantity of individuals, in terms of prey biomass, the most significant prey of North American great horned owls are hares and rabbits. About a dozen lagomorphs species are known to be hunted by the owl, from the relatively tiny pygmy rabbit to several hares weighing more than . Two hare species, the black-tailed jackrabbit and snowshoe hare, are so important to the owls as a food source that the local owl populations sharply rise and fall in sync with the hares' cyclical population trends.
Although the time of its extinction is uncertain, it possibly coincided with the general decrease in leporid diversity found in the Holocene. There is a dearth of knowledge about the evolutionary history of Nuralagus rex in relation to other lagomorphs. However, similarities between the dental morphology of Nuralagus and Eurasian members of the extinct genus Alilepus have led to speculation that Alilepus is closely related to and, possibly, the ancestor of Nuralagus. The theory that Alilepus gave rise to Nuralagus is apparently contradicted; Alilepus fossils found in Spain have been dated to the Quaternary period, well after Nuralagus would have been isolated on Menorca.
A leopard shark and two blacksmith chromis observed in kelp forest habitat at Birch Aquarium Trees of San Diego–Tijuana included chamise, scrub oak, manzanita, live oak, lodgepole pine, black oak and closed- cone pine forests. Lowland shrubs included California sagebrush, black sage, white sage, California buckwheat, as well as cacti and succulents. Terrestrial mammals included the mountain lion, bobcat, bighorn sheep, mule deer as well as a variety of rodents and lagomorphs including the California ground squirrel, San Diego kangaroo rat, and brush rabbit. Black bears, jaguars and sea otters historically populated the area, but their range has been restricted by human encroachment and the jaguar and the sea otter are now rarely, if ever, observed.
The precise physiological role of uteroglobin is not yet known. Putative functions are: # Immunomodulation # Progesterone binding: weak in some animals, especially weak in humans. (Note: UGB is itself progesterone induced gene in the endometrium in Lagomorphs) # Inhibits phospholipase A2 in vitro # Binds phosphatidylcholine, phosphatidylinositol # Binds to fibronectin: The uteroglobulin knockout mice on the inbred C57Bl6 strain develop Goodpasture's syndrome like glomerulopathy due to fibronectin binding of IgA which might potentially be prevented by uteroglobin replacement. However contrary to the animal model claims, human genetic data might suggest that the effect may be indirect # Uteroglobin knockout mice on the inbred 129 strain appear to have healthy phenotype (no glomerulopathy development), but show physiological differences in their responses to respiratory challenges.
Some pikas, such as the collared pika, have been known to store dead birds in their burrows for food during winter.Leininger, Charlene (2009) Ochotona collaris . Animal Diversity Web These animals are herbivores, and feed on a wide variety of plant matter, including forbs, grasses, sedges, shrub twigs, moss, and lichens. As with other lagomorphs, pikas have gnawing incisors and no canines, although they have fewer molars than rabbits; they have a dental formula of: Rock-dwelling pikas have small litters of fewer than five young, while the burrowing species tend to give birth to more young, and to breed more frequently, possibly due to a greater availability of resources in their native habitats.
Jackals in Turkey have been known to eat the eggs of the endangered green sea-turtle. In Hungary, their most frequent prey are common voles and bank voles. In Dalmatia, mammals (the majority being even-toed ungulates and lagomorphs) made up 50.3% of the golden jackal's diet, fruit seeds (14% each being common fig and common grape vine, while 4.6% are Juniperus oxycedrus) and vegetables 34.1%, insects (16% orthopteras, 12% beetles, and 3% dictyopteras) 29.5%, birds and their eggs 24.8%, artificial food 24%, and branches, leaves, and grass 24%. Information on the diet of jackals in North-Eastern Italy is scant, but it is certain that they prey on small roe deer and hares.
Skull from behind The unique characteristics of Myotragus balearicus are a consequence of a prolonged process of evolution on the islands (a clear example of island dwarfing). In this type of isolation, the ungulates tend to become smaller while rodents and lagomorphs increase their size, as happened to the Hypnomys, the giant dormouse that shared a habitat with Myotragus. Such species also tend to lose their fear reaction towards predators if none occur on the islands. A clear example of this is the loss of the capacity to run at high speed, the development of stereoscopic vision (which is useful to calculate distances, but not so to watch for predators) and the proportional reduction of the brain.
Illustration of a lesser bilby The lesser bilby was a medium- sized marsupial with a body mass of 300–435 grams, a combined head-body length of 200–270 millimetres and tail from 120 to 170 mm. Its fur colour ranged from pale yellowish-brown to grey-brown with pale white or yellowish-white fur on its belly, with white limbs and tail. The tail of this animal was long, about 70% of its total head-body length. Macrotis have long fur with a silky texture, the species have long tails and mobile ears that resemble those of a common rabbit (lagomorphs); they are burrowing animals that have long and narrow muzzles.
Plateau pikas have mating systems such as monogamous and polygynandrous groups, which contain about three males and 3 to 4 females per family along with their offspring. Females can produce 2 to 5 litters of about 2 to 7 offspring with a three-week interval in between each litter which is why this group of lagomorphs are known to have the fastest growth rates of their order. Their breeding season lasts from April to August and the young do not disperse in the year of birth. Males form hierarchies and females are usually philopatric forming reproductive alliances, helping each other in the care of their offspring, males also contribute in parental care when deterring a predator by emitting an alarm call.
Beyond the high significance of rabbits (and sometimes other lagomorphs), other mammals are rarely as important or diverse in the diet of Bonelli's eagles as birds are. A couple of rodents can be locally significant secondary prey, however. The red squirrel (Sciurus vulgaris), with a mean estimated mass in Spain of , was reported in almost all western Europe studies, with about 130 reported as taken in studies from Provence, France. The black rat (Rattus rattus), of similar size to the squirrel at an average of about was an important secondary food source in islands south and east of Greece, being the second most common prey species in Cyprus (15.5% of 528 prey items) and fifth most important prey species in the Aegean islands.
The European hare was also the second most common prey species in a study from the Czech Republic. Outside of southwestern Europe, the next closest association between lagomorphs and this species is in the arid steppe of southern Russia, hares are apparently the primary prey of the local eagle- owls. Little has been published in recent ornithological review, but old studies have indicated that the eagle-owls in this region are so dependent on hares, primarily again the mountain hare species, that cyclical reductions in numbers of the hares are followed immediately by a reduction of the local eagle-owls.Dementiev, G. P., Gladkov, N. A., Ptushenko, E. S., Spangenberg, E. P., & Sudilovskaya, A. M. (1951). Birds of the Soviet Union, vol. 1.
Passive immunity is also provided through colostrum and breast milk, which contain IgA antibodies that are transferred to the gut of the infant, providing local protection against disease causing bacteria and viruses until the newborn can synthesize its own antibodies.. Protection mediated by IgA is dependent on the length of time that an infant is breastfed, which is one of the reasons the World Health Organization recommends breastfeeding for at least the first two years of life. Other species besides humans transfer maternal antibodies before birth, including primates and lagomorphs (which includes rabbits and hares). In some of these species IgM can be transferred across the placenta as well as IgG. All other mammalian species predominantly or solely transfer maternal antibodies after birth through milk.
Such prey was estimated to weigh (for cottontail rabbits) and (for jackrabbits) in Idaho, meaning very small young rabbits and jackrabbits are likely captured. However, sometimes long-eared owls can very rarely capture exceptionally large lagomorphs. The record sized mammalian prey to be taken by a long-eared owl, was recorded in the case of predation upon a probable juvenile black-tailed jackrabbit (Lepus californicus) which weighed an estimated . Two instances of scavenging on carrion were reported in Italy, the first known case of this for the species, where long-eared owls consumed parts of an adult crested porcupine (Hystrix cristata) and an adult European pine marten (Martes martes), both prey the long-eared owls were certainly unlikely to have killed.
A culpeo feasting on carrion of vicuña at El Tatio, San Pedro de Atacama, the Antofagasta Region The culpeo fox is an opportunistic predator that will take any variety of prey. This fox mainly feeds on rodents and lagomorphs (especially the introduced European rabbit and European hare); however, it occasionally feeds on domestic livestock and young guanacos.Andres J. Novaro, Claudio A. Moraga, Cristobal Bricen, Martin C. Funes, Andrea Marino (2009) First records of culpeo (Lycalopex culpaeus) attacks and cooperative defense by guanacos (Lama guanicoe). Mammalia, Volume 73 Culpeos are considered beneficial because they are significant predators of the rabbits introduced in 1915; such introduced rabbit populations are believed to have allowed culpeos to spread from the Andean foothills across the Patagonian plain.
The dentary superficially resembles that of various other mammalian groups with enlarged incisors, such as rodents, lagomorphs, hyraxes, wombats, the aye-aye, and the extinct apatemyids, tillodonts, and taeniodonts--all of which are known only from the Cenozoic, less than 66 million years ago. Krause and colleagues could not exclude the possibility that TNM 02067 represents an early member of such a group or an otherwise unknown major group of mammals. However, only two groups of Mesozoic mammals resemble TNM 02067: gondwanatheres; and multituberculates in the superfamilies Djadochtatherioidea and Taeniolabidoidea. Djadochtatherioids and taeniolabidoids occur in the late Cretaceous through Paleogene of the northern continents (Laurasia), and gondwanatheres, an enigmatic group of uncertain evolutionary affinities, are known from the late Cretaceous through Paleogene of Gondwana, with forms such as Gondwanatherium, Sudamerica (both from Argentina), Lavanify (Madagascar), and Bharattherium (India).Gurovich and Beck, 2009, pp.
Meng and Wyss, 1994, p. 201 The loss of the second upper premolar (P2) has also been considered as synapomorphic for Simplicidentata, but the primitive simplicidentate Sinomylus does have a P2.McKenna and Meng, 2001, p. 565 This sense of Simplicidentata was introduced by Chuankui Li and colleagues in 1987, who ranked Simplicidentata as a superorder including Rodentia and the extinct Mixodontia, contrasted with the superorder Duplicidentata (including Lagomorpha and the extinct Mimotonida).Meng and Wyss, 1994, p. 199 In their 1997 book Classification of Mammals, Malcolm C. McKenna and Susan K. Bell ranked Simplicidentata as a mirorder within the grandorder Anagalida (also including lagomorphs, macroscelideans, and some additional extinct groups). Within Simplicidentata, they recognized the orders Mixodontia (including only the extinct family Eurymylidae from the Paleocene and Eocene of Asia) and Rodentia.McKenna and Bell, 1997, p.
However, the estimated average weight of rabbits taken can be variable, reported from as little as in a study from Spain to as much as in the Netherlands. Three other lagomorphs extensively overlap in range with Eurasian eagle-owls in Europe, the mountain hare (Lepus timidus) in the northern portions, the European hare (Lepus europaeus) in the central and eastern portions and the Granada hare (Lepus granatensis) in the western Mediterranean portions. These species are all larger on average than a rabbit, averaging in the Granada hare, roughly twice that in the European hare and the mountain hare being intermediate between the two. Hares are often considerably secondary in prey remains in most European biomes by number but often are a significant contributor of prey biomass for eagle-owls. For example, in Finland, the mountain hare made up only 5.3% of prey by number but made up 56.2% of the prey biomass as the hare specimens were all large, with an estimated mean mass of .
In the Great Basin, the owls share black-tailed jackrabbit and desert cottontail as the primary prey with golden eagles, red-tailed hawks and ferruginous hawks (Buteo regalis); all four species had diets with more than 90% of the biomass is made up of those lagomorphs. Of these, the great horned owl and golden eagle were able to nest most closely to one another because they had the most strongly dissimilar periods of activity. In California, when compared to the local red-tailed hawks and western diamondback rattlesnakes (Crotalus atrox), the diets were most similar in that by number about 15-20% of all three species' diets depended on cottontails, but the largest portion was made up of ground squirrels in the hawk and the rattlesnake and desert woodrats and other assorted rodents in the great horned owl. In the boreal forests, the great horned owl's prolificacy as a snowshoe hare hunter places it second only to the Canada lynx (Lynx canadensis) among all predators.
Accipiter hawks usually ambush birds in dense vegetation, a dangerous hunting method that requires great agility. Many smaller tropical species of Accipiter eat nearly equal portions of insects and reptiles and amphibians as they do of birds while some of the larger species have become more generalized, and may feed extensively on rodents and lagomorphs as well as other various non-avian animals. Most accipitrids will supplement their diet with non-putrid carrion but, of course, none specialized with this as well as the 14-16 species of vultures, which have evolved very large bodies (which leave them equipped to fill their crop with carrion), weaker, less specialized feet relative to other accipitrids, large wingspans to spend extensively periods of time in flight over openings scanning for carcasses and complex social behavior in order to establish a mixed species hierarchy at carrion. The New World vultures have attained several similar characteristics, but only through convergent evolution and are seemingly not directly related to Old World vultures and other accipitrids.
