Research Report: Dynamics of population growth by Cebus capucinus in Costa Rica
The population of white-faced capuchin monkeys (Cebus capucinus) in the Sector Santa Rosa (SSR) of the Area de Conservación Guanacaste in northwestern Costa Rica offers a unique opportunity to model how landscape variability affected selection on early hominins. This species shows many anatomical and behavioral convergences with great apes and humans, and they thrive in a broad range of environmental

Excavation of ‘Ein Qashish
Traditionally, studies of Levantine (eastern Mediterranean) Middle Paleolithic sites have focused on caves, and so exploration of the open-air ‘Ein Qashish site presents a novel opportunity to expand our understanding of the behavioral dynamics of Middle Paleolithic hominins (modern humans as well as Neanderthals) in the region.

Researchers have been performing daily focal observations and fecal sampling on this study group of habituated Assamese macaques in Thailand’s Phu Khieo Wildlife Sanctuary since October 2006. For her investigation of ecological, social and reproductive stress in female macaques, Julia Ostner used data collected between September 2007 and February 2009. This time period included two

Brigitte Spillmann was awarded a Leakey Foundation research grant in spring 2010 for her PhD project focusing on the functions of the long call, the long distance signal of the flanged male orangutan.
Long distance signaling in widely dispersed, semi-solitary species is often used to mediate
