title: Changes to acoustic communication systems in human-altered environments.
abstract: Animal communication systems have become closely tuned to local habitat conditions as populations have adjusted to different long-term environmental pressures. However, many habitats are now rapidly changing because of anthropogenic modification. Maintenance of effective communication systems in greatly altered environments will depend on communicative responses on both evolutionary and ontogenetic time scales. Consideration of potential acoustic challenges caused by human-generated habitat modification has important implications for basic research and conservation biology. First, the observed signal structure of individuals in altered environments may not match the normally hypothesized call structure. Second, species that either possess little ability to adapt quickly on an evolutionary time scale or have little plasticity in their communicative systems may be unable to respond to large anthropogenic alterations in their acoustic environment.
