I am interested in environmental effects upon lemur physiology. The ways in which species distribute energy in response to their environments can tell us how they resolve the competing needs of reproduction and survival. Long-term measures of cortisol, a stress hormone, provide a profile of energy use throughout environmental changes and highlight environmental processes which pose potential threats to energetic maintenance. In combination with detailed phenological and behavioral data we can further assess how species mitigate environmental stress. I am also interested in applying these methods to investigating the effects of habitat disturbance, an increasingly important topic around the world, and particularly Madagascar due to the high species endemism and high rates of deforestation. In collaboration with Dr. Mitch Irwin we will use physiological measures to study the impact of habitat disturbance upon a critically endangered primate, the Diadem Sifaka. As part of a study conducted by Drs. Patricia Wright and Laurie Godfrey, I have recently begun to study reproductive hormones in lemur species as well. Reproductive hormones can tell us a lot about the reproductive behavior of species which may not be possible to detect otherwise. Studying longevity and somatic senescence in our most primitive primate relatives will also help us understand this process in humans. I have also been involved in measuring androgen levels in Propithecus verreauxi with Dr. Rebecca Lewis as part of a larger project on lemur alternative mating tactics. Finally, I am also interested in cooperative breeding. All Eulemur rubriventer group members, including juvenile males and females, carry infants. In lemurs this behavior has rarely been reported for group members other than fathers. Deeper investigation into this behavior in lemurs, and comparisons between cooperative breeding in lemurs and Callitrichids, is a new and promising avenue of research into the evolution of this behavior.
