Research

Professor Sauther’s major focus of research is to better understand how both immediate and long-term environmental factors interact with inter-individual variation to affect primate behavior and biology. In essence, she is very interested in how primates “negotiate” living within a variety of environments. Her current research focuses on understanding how environmental stressors such as anthropogenic-induced factors and climate impact both the biology and behavior of wild primates. Her research combines both field work and collaborative laboratory work with geneticists, research veterinarians and others to assess biological markers of ecological stress that includes biometrics, genetics, physiological and health measures.

Graduate Students Interested in Working with Professor Sauther

Southern Africa Galago Ecology, Biology and Behavior.

Professor Sauther is currently co-directing the Southern Africa Galago Project at the Lajuma Research Centre, South Africa, which focuses on the comparative ecology, health and thermoregulation of two sympatric species of wild Galagos, Otolemur crassicaudatus and Galago moholi. For this project, she is looking for students interested in nocturnal galago ecology, biology and behavior. Prospective students preferably will have some background/experience in the study of nocturnal mammals and wildlife biology field methods.

Primate dental ecology – how teeth can provide a window into environmental change and reflect the use of the environment.

Professor Sauther’s research laboratory also contains one of the largest collections of longitudinal, wild strepsirrhine dental impressions of Lemur catta collected from her decades long research on this species at Beza Mahafaly, Madagascar. Her collection also includes a large longitudinal and cross-sectional collection of dental impressions of wild Otolemur crassicaudatus from the Lajuma Research Centre.  For this research she is interested in students wanting to conduct original research on the dental ecology of these species. Students should have a working knowledge of modern techniques for studying dentition such as dental topographic analysis using geographic information systems (GIS) and laser scanning methodology.
