The capacity for sperm storage within the female reproductive tract occurs widely across all
groups of vertebrate species and is exceptionally well developed in some reptiles (maximum …

The use of regression analysis has been instrumental in allowing evolutionary biologists to
estimate the strength and mode of natural selection. Although directional and correlational …

Male mammals often kill conspecific offspring. The benefits of such infanticide to males, and
its costs to females, probably vary across mammalian social and mating systems. We used …

The good-sperm and sexy-sperm (GS-SS) hypotheses predict that female multiple mating
(polyandry) can fuel sexual selection for heritable male traits that promote success in sperm …

Females often mate with several males before producing offspring. Field studies of
vertebrates suggest, and laboratory experiments on invertebrates confirm, that even when …

In most mammalian species, females regularly interact with kin, which is expected to reduce
aggressive competitive behaviour among females. It may thus be difficult to understand why …

Suicidal reproduction (semelparity) has evolved in only four genera of mammals. In these
insectivorous marsupials, all males die after mating, when failure of the corticosteroid …

Previous studies have attempted to assess the reproductive benefits of polyandry in
mammals but have failed to account for variation in mating frequency across experimental …

The use of multiple source populations provides a way to maximise genetic variation and
reduce the impacts of inbreeding depression in newly established translocated populations …

Parentage analyses of baleen whales are rare, and although mating systems have been
hypothesized for some species, little data on realized male reproductive success are …
