The alpha couple will actively discourage last years offspring from mating to ensure that there are not more mouths to feed, but a young male seems adamant to pursue the interest of one young female Jump to. Sections of this page. Accessibility Help. Email or Phone Password Forgot account?
Evidence for sex-specific reproductive senescence in monogamous cooperatively breeding red wolves
Wolf Country, reproduction, bonding and mating
This order is constantly reinforced by displays of dominance and submission. Unfortunately, the omega bears the brunt of this behavior. One or many of the wolves will assert themselves over the omega, who flips over onto his back, whimpering in surrender. Generally this is a bloodless exchange, but at times, especially during the breeding season, it can get vicious and extremely difficult to watch. In wolf hierarchy, the males tend to dominate other males and the females dominate other females so that there is generally a low ranking member of each sex. The alpha pair would never allow the omega male and female to mate, therefore the omegas are not pair-bonded to each other like the alphas. In the beginning of the project, the Sawtooth Pack was small, consisting only of five males.
Wolf reproduction, bonding and mating
While food sharing among related individuals can be explained by kin selection, food sharing between unrelated individuals has been more of an evolutionary puzzle. The food-for-sex hypothesis provides an explanation for the occurrence of food sharing among nonkin. However, little is known about the socio-ecological factors that can promote such a commodity exchange.






Sex-specific senescence has been construed as a function of mating system and differential investment in parental care, with males exhibiting low parental investment predicted to have more rapid senescence due to costly reproductive behavior. In monogamous mating systems, however, where parental investment may be more evenly distributed, rates of senescence are predicted to be more equivalent between the sexes than in polygynous mating systems. While many polygynous species do appear to support this pattern, evidence from monogamous species, particularly mammals, is scarce. Wolves are an excellent system with which to test this hypothesis, as they exhibit both monogamy and cooperative breeding, where parental investment is distributed across both breeders and non-breeders of both sexes. We examined patterns of age-specific reproduction in red wolves and red wolf-coyote hybrids.
