Female hierarchy instability, male immigration and infanticide increase glucocorticoid levels in female chacma baboons

Female baboons (Papio hamadryas spp.) must contend with myriad potential stressors on a daily basis. In a previous study on female chacma baboons, Papio hamadryas ursinus, living in the Okavango Delta of Botswana, increases in glucocorticoid (GC) concentrations were associated with female reproductive stage, male immigration and the threat of infanticide. Here, we extend this previous analysis ...

Infanticide as sexual conflict: coevolution of male strategies and female counterstrategies.

One of the earliest recognized forms of sexual conflict was infanticide by males, which imposes serious costs on female reproductive success. Here I review two bodies of evidence addressing coevolved strategies of males and females. The original sexual selection hypothesis arguing that infanticide improves male mating success by accelerating the return of females to fertilizable condition has b...

Impact of Male Infanticide on the Social Structure of Mountain Gorillas

Infanticide can be a major influence upon the social structure of species in which females maintain long-term associations with males. Previous studies have suggested that female mountain gorillas benefit from residing in multimale groups because infanticide occurs when one-male groups disintegrate after the dominant male dies. Here we measure the impact of infanticide on the reproductive succe...

Reply to Lukas and Clutton-Brock: Infanticide still drives primate. monogamy.

For many years, it has been variously suggested that the evolution of monogamy in primates was due to paternal care, dispersed female ranging, or infanticide. It was therefore of little surprise to us that we should find that these traits are strongly associated with mating systems in primates (1). The crucial question, however, is whether these traits are potential drivers of, or secondary res...
