Renato Francisco Borras Chavez

Postdoctoral Researcher

University of Rhode Island

Kingstone, Estados Unidos

My work is centered on Foraging Ecology, Population Ecology and Ecophysiology of Marine Megafauna. I used different dietary proxis to connect what species consume with their population dynamics, their physiology, and the human-megafauna interactions
