During the latter half of the last century, evidence of reproductive competition between males
and male selection by females led to the development of a stereotypical view of sex …

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 …

Social interactions help group-living organisms cope with socio-environmental challenges

It is believed that domestic dogs rarely form packs with age-graded hierarchical structures
similar to those found in wolves. Dog-wolf comparisons in captivity suggest that human …

Long-term studies of cooperatively breeding vertebrates offer excellent opportunities to test
theories about the evolution of cooperation and the demographic consequences of social …
