Mating strategies and reproductive endocrinology of female lowland woolly monkeys (Lagothrix logotricha poeppigii): Implications for female mate choice in a promiscuous primate.
Research update: Woolly monkey mating season and the perks of field work in the Amazon rainforest.
The Amazon is a notoriously wet and humid place, I mean it's called a RAINforest afterall. However, between the months of July and August our field site recieves the least amount of rainfall of the year and it can get really hot! Perhaps this is why our study subjects, Woolly monkeys...read more
Adaptations for insectivory in digestive enzymes of new world primates.
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
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
