The ecology and behavior of the four species of Rhinopithecus, snub‐nosed monkeys, are
rapidly becoming well known. New field studies reveal in depth the striking adaptations of …

Ethiopia is home to one of the richest and most unique assemblages of fauna and flora on
the African continent. Contained within its borders are two major centers of endemism, the …

Foods derived from C4 plants were important in the dietary ecology of early Pleistocene
hominins in southern and eastern Africa, but the origins and geographic variability of this …

Hamadryas baboons are known for their complex, multi‐level social structure consisting of
troops, bands, and one‐male units (OMUs)[Kummer, 1968. Social organization of …

Multilevel societies are unique in their ability to facilitate the maintenance of strong and
consistent social bonds among some individuals while allowing separation among others …

This chapter reviews the extent of primate gummivory, identifies phylogentic patterns in the
degree of gummivory across primates, and examines overlap in the plant species whose …

Bifidobacteria, which commonly inhabit the primate gut, are beneficial contributors to host
wellbeing. Anatomical differences and natural habitat allow an arrangement of primates into …

A long-standing hypothesis in ecology and evolution is that trichromatic colour vision (the
ability to distinguish red from green) in frugivorous primates has evolved as an adaptation to …

The multilevel society of hamadryas baboons, consisting of troops, bands, clans, and one‐
male units (OMUs), is commonly perceived to be an effective means of adapting to variable …

Unlike most cercopithecines, hamadryas baboons (Papio hamadryas hamadryas) are
characterized by female‐biased dispersal. To clarify this pattern within the context of their …
