Host-associated microbiomes play an increasingly appreciated role in animal metabolism,
immunity and health. The microbes in turn depend on their host for resources and can be …

Whether inbreeding affects the demography and persistence of natural populations has
been questioned. However, new pedigree data from field populations and molecular and …

Relatives have more similar gut microbiomes than nonrelatives, but the degree to which this
similarity results from shared genotypes versus shared environments has been …

Social relationships have profound effects on health in humans and other primates, but the
mechanisms that explain this relationship are not well understood. Using shotgun …

The chimpanzees are the closest living evolutionary relatives to our own species, Homo
sapiens. As such, they have long exerted a fascination over those with an interest in human …

Considerable interspecific variation in female social relationships occurs in gregarious
primates, particularly with regard to agonism and cooperation between females and to the …

We review evolutionary processes and mechanisms that gave rise to the diversity of primate
social systems. We define social organization, social structure and mating system as distinct …

Despite its practical application in conservation biology and evolutionary theory, the cost of
inbreeding in natural populations of plants and animals remains to a large degree unknown …

Small populations lose genetic variability because of genetic drift, and inbreeding within
populations can further decrease individual variability. Lower variation depresses individual …
