Reproductive senescence is evident across many mammalian species. An emerging
perspective considers components of reproductive senescence as evolutionarily distinct …

Sexual segregation is widespread in mammals, although the proximate causes are poorly
understood in monomorphic species. Indo-Pacific bottlenose dolphins (Tursiops aduncus) …

Inbreeding often imposes net fitness costs, 1–5 leading to the expectation that animals will
engage in inbreeding avoidance when the costs of doing so are not prohibitive. 4–9 …

Bottlenose dolphins (Tursiops spp.) live in complex societies with high fission-fusion
dynamics and exhibit a polygynandrous mating system in which both sexes mate with …

Odontocetes are characterized by slow life histories and extensive maternal care, where
offspring nurse for years in some species. Among some of the largest toothed whales, the …

Infanticide by adult males is a striking example of sexual confiict; males can increase their
reproductive success by killing an unrelated infant and accelerating the mother's return to …

The juvenile period is a challenging life-history stage, especially in species with a high
degree of fission–fusion dynamics, such as bottlenose dolphins, where maternal protection …

Kinship plays a fundamental role in the evolution of social systems and is considered a key
driver of group living. To understand the role of kinship in the formation and maintenance of …

In mammals, reproductive success can often be directly observed for females, but not males.
Early-life correlates of female reproductive success can also be easier to observe due to …

Social living brings competition over mates, relationships, and resources, which can
translate to direct conflict. In dolphins, tooth rakes received from conspecifics are highly …
