摘要：

Signal plasticity is a building block of complex animal communication systems. A particular form of signal plasticity is the Lombard effect, in which

get approach. Under severe interference, bats emitted calls of higher intensity and longer duration, and called more often. Slight spectral shifts were observed

Data from: Males increase call frequency, not intensity, in response to noise, revealing no Lombard effect in the little torrent frog

摘要：

Noise is one of the main factors that can influence the processes of sound communication across a wide range of animal groups. Although the effect
