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.
随着种群适应不同的长期环境压力，动物的通讯系统已与当地栖息地条件紧密协调。然而，由于人为改造，许多栖息地正在迅速变化。在大幅改变的环境中维持有效的通讯系统将取决于进化和个体发育时间尺度上的通讯反应。考虑人为造成的栖息地改造所带来的潜在声学挑战，对基础研究和保护生物学具有重要意义。首先，在改变的环境中观察到的个体信号结构可能与通常假设的叫声结构不匹配。其次，那些在进化时间尺度上几乎没有快速适应能力或其通讯系统几乎没有可塑性的物种，可能无法应对其声学环境中人为造成的巨大变化。
