Tavi Steinhardt studies behavioral evolution at UC Berkeley and has been working with FPI since 2017. He’s interested in how tamarin social groups are affected by their ecological interactions with the forest. Why do tamarin groups have so many breeding males and so few breeding females (in contrast to the system you’d find in, say gorillas)? Why do their home ranges vary so much in size? Are some forest types more valuable to a tamarin than others? To answer these questions, Tavi will be at the Los Amigos Biological Station in Peru fitting tamarins with GPS collars, which will help us learn exactly where the animals go, what they do, and how they make use of different microhabitats in the forest.
