The Consequence Of Anthropogenic Disturbance On Communication And The Operation Of Sexual Selection In The Eastern Bluebird (Sialia Sialis), Ellen Michale Wisner

Biology - Dissertations

Signals that are efficiently transmitted and easily detected in their signaling environment are favored by natural selection. Anthropogenic disturbance can rapidly alter the signaling environment, and recent studies have shown that acoustic and visual signals change in response to these altered habitats. Although these studies provide important insight into the effects of urbanization on animal signals and have served as experiments testing the role of the environment in shaping signal design, several key aspects of how signal design can be influenced by environmental changes remain unclear.

Previous studies have focused on signals used between adults, such as those used in …
