Foraging and nutrient acquisition are fundamental to a species’ survival, influencing their growth, reproduction and ultimately population viability. The Marine Turtle Research, Ecology, and Conservation Group addresses research questions related to how marine turtles interact with their environment, through their foraging and feeding strategies, including diet composition and selection and how these changes over time. Our projects also aim to better understand how alterations on species foraging ecology may affect marine ecosystems and on determining the ecological roles of marine turtles.
