Sexual interference in stumptail macaques (Macaca arctoides) : is it return-benefit spite?

Abstract

The phenomenon of intervening with other’s matings, or sexual interference, was studied in a free-ranging group of stumptail macaques (Macaca arctoides). This thesis suggests that its function may be immediately spiteful, but also ultimately beneficial reproductively. Preliminary evidence in support of this contention is presented, and speculations on related questions ate offered. A proposed evolutionary scenario of the stumptail macaque mating pattern is also outlined.
