Many mammalian species use chemosignals to coordinate reproduction by altering the
physiology and behavior of both sexes. Chemosignals prime reproductive physiology so that …

Chemical communication plays many key roles in mammalian reproduction, although
attention has focused particularly on male scent signalling. Here, we review evidence that …

Within-group variation in sociality has been linked to correlates of fitness across vertebrates.
Individuals that form strong social bonds with a few partners, or are well integrated into a …

Body size is a key determinant of male fighting ability and reproductive success in many
animal species, but relationships between these variables have only rarely been examined …

Behavioral ecologists frequently use observational methods, such as instantaneous scan
sampling, to record the behavior of animals at discrete moments in time. We develop and …

African large mammals are under extreme pressure from unsustainable hunting and habitat
loss. Certain traits make large mammals particularly vulnerable. These include late age at …

Natural selection will favor male care when males have limited alternative mating
opportunities, can invest in their own offspring, and when care enhances males' fitness …

The extraction of timber often conflicts with the well-being and conservation of wildlife. In
particular, there is a need to better understand the impact of tree removal under selective …

How do women's sexual interests change across their ovulatory cycles? This question is one
of the most enduring within the human evolutionary behavioral sciences. Yet definitive …

Close associations between adult males and females are rare among group-living,
nonmonogamous mammals but may mark the transition from life in promiscuous bisexual …
