Thus these bulls have more reproductive success. Musth appears to signal to females the condition of the male, as weak or injured males do not have normal musths.Sukumar, p. 117. For young females, the approach of an older bull can be intimidating, so her relatives stay nearby to provide support and reassurance.

Females in a reproductive unit exist in a hierarchy, with higher- ranking females having more reproductive success and more offspring than lower-ranking females. Closely related females tend to have a similar hierarchical status. Females generally stay in their natal units for life; cases of females leaving are rare. Aggression within a reproduction unit, which is rare, is usually just between the females.

The Mesozoa (singular: mesozoan) are minuscule, worm-like parasites of marine invertebrates. Generally, these tiny, elusive creatures consist of a somatoderm (outer layer) of ciliated cells surrounding one or more reproductive cells. Decades ago, Mesozoa were classified as a phylum. Molecular phylogeny studies, however, have shown that the mysterious mesozoans are monophyletic, and emerged in the Lophotrochozoa as sister of the Rouphozoa.

The S. mexicana species form large perennial colonies which are divided based by communication methods. They have a tendency to form drone congregations, consisting of approximately 132 colonies. The better the environment and the more steady food supply that exists, the more reproductive swarms and more drones are formed. Based on how these swarms align, there are genetically related colonies formed around a mother nest, thus eventually resulting in the drone formation.

The colonies that are supplemented with food also produced more reproductive females than larger reproductive females which suggests that female sexual production in resource limited conditions is very expensive. Males however, are slightly larger on average which could mean that the number of males produced is not as critical as male size. It has been proposed that larger males helps the colony by attacking foreign males, and defending nest territory.Seal, J.N., and J.H. Hunt.

Females associate with the same individuals in the same location for several years unaffected by changes in resident males and movements of the group to different roosts. A male may stay with a female group for two or more reproductive seasons. Bachelor males are segregated from the females and may roost alone or together in small groups. Female bats forage either alone or with their roost mates, with stable female groups continue to forage in the same areas in the long term.

In addition, studies suggest that consumers desire more reproductive genetic testing, particularly for diseases that wil result in death by the age of 5. In the traditional medical model, screening for the Jewish genetic diseases usually is recommended by a woman’s obstetrician/gynecologist once the woman is contemplating a pregnancy or already pregnant. As an alternative model, community-based carrier screening programs have been established nationwide. In addition to spreading further awareness about genetic health issues, screening programs allow for carriers to be identified prior to pregnancy, and even prior to picking a future marriage partner.

To get the workers to remain with the nest and continue to aid her own offspring, the queen often cedes reproduction to alien workers. These workers can produce males or gynes and have high rates of reproduction. They do not, however, overwinter, nor are they morphologically similar to a queen or gyne. The length of lifespan for the queens may be a factor that leads to more reproductive workers in southern climes that have longer breeding seasons; in northern climes, where the queen is generally alive for production of gynes, workers are less likely to be reproductive.

Studies have shown that in optimal conditions a single female A. ritzemabosi can produce up to thousands of offspring in the period of about a month.J. S. DOLLIVER 1), A. C. HILDEBRANDT, & A. J. RIKERSTUDIES OF REPRODUCTION OF APHELENCHOIDES RITZEMABOSI (SCHWARTZ) ON PLANT TISSUES IN CULTURE. Department of Plant Pathology, University of Wisconsin, Madison, U.S.A. 2) French & Barraclough (1961) obtained a maximum number of 3,500 progeny from a single A. ritzemabosi female after 38 days at mean greenhouse temperatures of 17° to 23 °C. Temperature influence on reproduction showed that higher temperatures generally lead to more reproductive actions.

Abortion in Zimbabwe is available under limited circumstances. Zimbabwe's current abortion law, the Termination of Pregnancy Act, was enacted by Rhodesia's white minority government in 1977. The law permits abortion if the pregnancy endangers the life of the woman or threatens to permanently impair her physical health, if the child may be born with serious physical or mental defects, or if the fetus was conceived as a result of rape or incest.ZIMBABWE: Abortion figures underscore need for more reproductive health education IRIN News, 30 March 2005 Nevertheless, an estimated 70,000+ illegal abortions are performed in Zimbabwe each year, resulting in around 20,000 maternal deaths.

Explained by the gravity hypothesis, outcompeting larger males thus having more reproductive success, especially when females live in high patches of flowers, whereas females live in low lying areas, larger males are favored. In spiders like Tetragnathidae, Araneidae, Thomisidae and Pholicidae there is an optimal body size that favors climbing speed. Smaller males will have an advantage over the largest males of the species, however the smallest male will not be the fastest climber. This optimal body size for climbing is observed in different males from the same species express phenotypes, weapons such as chelicerae, teeth or even legs to fight off competition are used to fight off oncoming rivals, with larger bodied spiders contained larger chelicerae.

These mechanisms are a part of evolutionary change because they operate in a way that causes the qualities that are desired in a mate to be more frequently passed on to each generation over time. For example, if female peacocks desire mates who have a colourful plumage, then this trait will increase in frequency over time as male peacocks with a colourful plumage will have more reproductive success. Further investigation of this concept, has found that it is in fact the specific trait of blue and green colour near the eyespot that seems to increase the females likelihood of mating with a specific peacock. Mate choice is one of two components of sexual selection, the other being intrasexual selection.

Meanwhile, in warmer and wetter and/or more humid conditions, rufous morph individuals are better adapted. However, similar studies on climate, habitat and colour morph found no strong correlation between colour morph, habitat and survivorship in Switzerland. Studies on colour morphs also indicated that higher levels of melanin, such as darker rufous morphs, may suffer higher rates of parasitism, body mass loss through the season across all ages but on the contrary also had higher growth rates for nestlings and were more likely to breed every year than grey morphs in Italy and Switzerland regardless of prey resources than grey morphs. Studies in Finland indicate that grey morph tawny owls have more reproductive success, better immune resistance, and fewer parasites than other morphs.

Sequential hermaphrodites almost always have a sex ratio biased towards the birth sex, and consequently experience significantly more reproductive success after switching sexes. According to the population genetics theory, this should decrease genetic diversity and effective population size (Ne). However, a study of two ecologically similar santer sea bream (gonochoric) and slinger sea bream (protogynous) in South African waters found that genetic diversities were similar in the two species, and while Ne was lower in the instant for the sex-changer, they were similar over a relatively short time horizon. The ability of these organisms to change biological sex has allowed for better reproductive success based on the ability for certain genes to pass down more easily from generation to generation.

Many non-human animals have been shown to be able to distinguish between potential partners, based upon levels of FA. As with humans, lower levels of FA are seen in the most reproductively successful members of species. For instance, FA of male forewing length seem to have an important role in successful mating for many insect species, such as dark-wing damselflies and Japanese scorpionflies. In the dark-winged damselfly (Calopteryx maculate), successfully mating male flies showed significantly lower levels of FA in their forewings than unsuccessful males, while for Japanese scorpionflies, FA levels are a good predictor for the outcome of fights between males in that more symmetrical males won significantly more fights. Other animals also show similar patterns, for example, many species of butterfly, males with lower levels of FA tended to live longer and flew more actively, allowing them to have more reproductive success.

He accused them of making "sweeping species-wide statements about male-female mating preferences", such as that humans are "mildly polygynous", based on superseded sociobiological predictions, of basing their claims on "pop books", and of engaging in "an impassioned and rambling bashing of the social sciences", and of wrongly considering an "any trait that seems well designed" to be an adaptation. He criticized their use of The Evolution of Human Sexuality, describing it as "an early think piece". He maintained that their data actually showed that rape has more reproductive costs than benefits and therefore cannot be a mating adaptation, and concluded that A Natural History of Rape was oversimplified, "the worst that evolutionary psychology has to offer", and damaged "both the cause of rape prevention and that of evolutionary psychology." Greenberg believed that Thornhill and Palmer correctly acknowledged "the contribution of sexuality to rape", but that their "theoretical discussion" was "weak".
