Meeting Abstract 83.3  Monday, Jan. 6 11:00  The role of a fluctuating environment on multiple signals SIMPSON, RK*; MCGRAW, KJ; Arizona State University; Arizona State University rksimps1@asu.edu Many animals communicate using more than one modality (e.g. acoustic, visual), and several hypotheses have arisen to explain the evolution of multiple signals. These hypotheses typically assume static selection pressures […]
