The International Primatological Society was created to encourage all areas of non-human primatological scientific research, to facilitate cooperation among scientists of all nationalities engaged in primate research, and to promote the conservation of all primate species. The Society is organized exclusively for scientific, educational and charitable purposes.

Influence of Fruit Availability on the Fission-Fusion Dynamics of Spider Monkeys (Ateles geoffroyi)

Braulio Pinacho-Guendulain & Gabriel Ramos-Fernández

Socioecological theory proposes that the flexibility in grouping patterns afforded by fission-fusion dynamics allows animals to cope with spatiotemporal variability in food abundance. We investigate the influence of fruit tree abundance and foragiing environment... read more.

 

Modeling Social Dominance: Elo-Ratings, Prior History, and the Intensity of Aggression

Nicholas E. Newton-Fisher

Among studies of social species, it is common practice to rank individuals using dyadic social dominance relationships. The Elo-rating method for achieving this is powerful and increasingly popular, particularly among studies of non-human priamtes, but suffers from... read more.

Adaptations for insectivory in digestive enzymes of new world primates.

Mareike Janiak

My research looks at enzymes that are produced in the guts of primates. All animals produce these enzymes to help them digest the foods they eat and I am trying to figure out if different primates have specialized enzymes depending on what foods they eat on a regular basis. ...read more

 

The energetics of male reproductive strategies in geladas (Theropithecus gelada).

Rachel F. Perlman

Energy is classically considered a main limiting factor in the reproductive success of female primates, but not males. Yet males may also face energetic constraints, particularly when reproductive strategies involve direct competition. Such competitive behaviors are often mediated by testosterone, and because testosterone production is itself sensitive to nutritional shortfalls, testosterone-dependent behaviors and thus male reproduction is likely constrained by energetic condition. ...read more

 

Climate Change, Coups, and Critically Endangered Species: First Aerial Drone Surveys of Madagascar's Lemurs 

Brandon Semel

Critically endangered golden-crowned sifakas are found only in northern Madagascar. Traditional walking surveys in 2006/2008 suggested that at least 18,000 remained. Madagascar’s 2009 coup brought increased habitat loss and hunting across the species’ habitat while climate change continues to pose an additional, less tangible threat to the species’ persistence. ...read more
