The major focus of my current research is life history of turtles, particularly the relationships among age at first reproduction, reproductive output, body size and growth rates and longevity. I am also especially interested in the changes in correlation among life history measures when these measures are examined among species, among populations, among individuals and within individuals over time. I also am investigating temperature dependent sex determination in turtles and how species with TDSD control sex ratio. Some of my graduate students are examining thermoregulation and temperature selection in relation to home range dynamics in the snapping turtle. I am also interested in the social behaviour of small mammals particularly infanticide and parental care and the evolution of these behaviour patterns.
