In most social mammals, some females disperse from their natal group while others remain
and breed there throughout their lives but, in a few, females typically disperse after …

Reproductive performance is the currency of evolution. All things being equal, an organism
should reproduce as often as possible. The puzzling questions in evolutionary biology …

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 …

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 …

Infanticide can be a major influence upon the social structure of species in which females
maintain long-term associations with males. Previous studies have suggested that female …

Group‐level male–male co‐operation, which has been documented in several primate and
non‐primate societies, may be mutualistically advantageous to the participants when …

Habitat fragmentation may strongly impact population genetic structure and reduce the
genetic diversity and viability of small and isolated populations. The white-headed langur …

Many nonseasonally breeding mammals demonstrate some degree of synchrony in births,
which is generally associated with ecological factors that mediate fecundity. However …

In primates and other mammals, weaning is an equivocal concept, as is reflected in the
numerous ways it is measured: a) first intake of solid food, b) conflict over access to the …

Accurate data on reproductive parameters are essential for evaluating the adaptive and
mechanistic bases of variation within and between species. Here, we combine fecal ovarian …
