Meredith Palmer, 2015 -

Meredith Palmer

Meredith Palmer is a PhD candidate at the University of Minnesota, where she studies the impacts of predation pressure on prey behavior. She is currently exploring how different predator attributes, such as hunting technique, shape adaptive anti-predator behavioral responses. Her work is conducted primarily in Serengeti Park, Tanzania, where she uses a 200+ camera trap grid ( to examine how variation in predation risk across space and time - the so-called "landscape of fear" - affects ungulate distribution and activity patterns. She is currently conducting additional experiments in South African reserves to study prey responses to simulated predator encounters. Prior to pursuing graduate school, Meredith worked on a variety of field research projects in Central and South America, Africa, and the South Pacific, studying organisms ranging from invasive snakes to endangered felines.
