The monitoring of endocrine markers that inform about an animal's physiological state has
become an invaluable tool for studying the behavioral ecology of primates. While the …

Each organism in the animal kingdom has evolved to detect and process a specific set of
stimuli in its environment. Studies of an animal's socioecology can help us to identify these …

Research conducted in the last fifteen years has placed in question many of the traditional
conclusions scholars have formed about human female sexuality. Though conventional …

Competition for fertile females determines male reproductive success in many species. The
priority of access model predicts that male dominance rank determines access to females …

In mammals, high dominance rank among males is often associated with mating success.
However, mating opportunities do not automatically translate into offspring production; …

Male mate-guarding episodes ('consortships'), are taxonomically widespread, yet costly to
individual males. Consequently, males should bias consortships toward females with whom …

Reproductive skew models have been proposed as a unifying framework for understanding
animal social systems, but few studies have investigated reproductive skew in a broad …

We analyzed patterns of paternity and male dominance rank in the Sonso community of wild
East African chimpanzees (Pan troglodytes schweinfurthii) in the Budongo Forest, Uganda …

Sexual competition is highly prevalent within multi-male multi-female primate groups and
may lead to copulations in absence of potentially interfering bystanders. Such avoidance of …

Social bonds, here defined as strong, equitable and enduring social relationships, increase
fitness in both male and female primates irrespective of their dispersal regime. Despite the …
