The diversity of extant carnivores provides valuable opportunities for comparative research
to illuminate general patterns of mammalian social evolution. Recent field studies on …

While males are generally the low investing sex when it comes to offspring care, males of
many species experience intense and persistent mating effort. Mating effort incurs a variety …

The evolution of cooperation in animal and human societies is associated with mechanisms
to suppress individual selfishness. In insect societies, queens and workers enforce …

In many animal societies, a small proportion of dominant females monopolize reproduction
by actively suppressing subordinates. Theory assumes that this is because subordinate …

Conflicts of interest over resources or reproduction among individuals in a social group have
long been considered to result in automatic and universal costs to group living. However …

Here we argue that models developed to examine cooperation and conflict in communal
breeders, using a “tug-of-war” model of reproductive skew generated by incomplete control …

Background. Parental absences in childhood are often associated with accelerated
reproductive maturity in humans. These results are counterintuitive for evolutionary social …

The publication of this issue marks the 25th anniversary of Behavioral Ecology, the flagship
journal of the International Society for Behavioral Ecology (ISBE). The society itself was …

Here, we argue that behavioral ecologists can do even more than we have done to facilitate
new, interdisciplinary collaborations. Our argument is a general one, but we focus on how to …

Background In insect societies, intracolonial genetic variation is predicted to affect both
colony efficiency and reproductive skew. However, because the effects of genetic variation …
