I. Focus of Research
The Turtle Ecology Lab at Missouri State University conducts conservation-driven research on freshwater and terrestrial turtles, with an emphasis on long-lived, imperiled species such as Alligator Snapping Turtles (Macrochelys temminckii) and Central American River Turtles (Dermatemys mawii), among others. Recent projects in my lab integrate field ecology, behavior, reproductive biology, and physiology to inform conservation management and reintroduction strategies. Current work includes extensive population surveys, telemetry-based studies of activity patterns and movement, investigations of nesting and reproductive cycles, and assessments of post-release performance of reintroduced individuals. My lab also explores functional morphology (e.g., bite performance, strike kinematics, shell kinesis) and endocrinology, and is expanding into stable isotope analyses to assess trophic structure of turtle communities. With ongoing collaborations in the U.S. and Belize, my lab prioritizes applied research that contributes directly to species recovery planning and habitat protection efforts.
