Navigating in a Rainforest: Movement Patterns in a Neotropical Primate. The Black Howler Monkey
… energy-minimizing Neotropical primate, the black howler monkey (Alouatta pigra). Specifically, I explored: (1) how black howler monkeys structure the space wherein they live (i.e., cognitive maps); (2) the influence of landscape features in their movement patterns; (3) their ability to navigate …
