Chimpanzees (Pan troglodytes) are the only great apes that inhabit hot, dry, and open
savannas. We review the environmental pressures of savannas on chimpanzees, such as …

Bipedalism, a defining feature of the human lineage, is thought to have evolved as forests
retreated in the late Miocene-Pliocene. Chimpanzees living in analogous habitats to early …

Any change in the energetic cost of mammalian mastication will affect the net energy gain
from foods. Although the energetic efficiency of masticatory effort is fundamental in …

Dental caries has been reported in a variety of primates, although it is still considered rare in
wild populations. In this study, 11 catarrhine primate taxa (n= 339 individuals; 7946 teeth) …

Reconstructing diets from stable carbon isotopic signals in enamel bioapatite requires the
application of a δ 13 C enamel-diet enrichment factor, or the isotopic offset between diet and …

Although historically habituation has largely been the default method in field primatology,
the COVID-19 pandemic has forced us to re-examine the possible detrimental effects of …

Premasticated food transfer, when an individual partially breaks down food through chewing
and feeds it to another individual, usually mouth-to-mouth, is described widely across …

In recent years, new applications of microremain dietary analysis using dental calculus as a
source of dietary data on ancient human subsistence and behaviours have accelerated. The …

Objectives Food scarcity is proposed to be a limitation to chimpanzees at the limits of their
range; however, such a constraint has never been investigated in this context. We …

Estimating stable isotopic offset values is crucial for dietary reconstructions. Although
research into stable isotope ecology of wild nonhuman primates is increasing overall, only a …
