New Publication from E. Coggeshall and Co-Authors Explores Behavioral Edge Effects in the Vocal Communication Behavior of Mantled Howler Monkeys

A new publication from Primate Behavior Master's student Elizabeth Coggeshall and co-authors Laura M. Bolt, Amy L. Schreier, Dorian G. Russell, Zachary S. Jacobson, Carrie Merrigan‐Johnson, and Matthew C. Barton explores behavioral edge effects in the communication behavior of Mantled howler monkeys (Alouatta palliata) at La Suerte Biological Research Station (LSBRS) fragmented tropical rainforest in Costa Rica. They found that howling bouts were longer and more frequent within each bout in the forest interior as compared to individuals living in the anthropogenic forest edge. These findings partially support the ecological defence hypothesis, that individuals living in areas with high forest quality will howl longer to advertise to surrounding groups that this territory of high species richness and canopy cover is occupied.
