Journal Article
Gonçalves Santos, S., Pieretti, N., Young, R., & Duarte, M. (2021). Biophony in a noisy tropical urban forest fragment. Biota Colombiana, 22(1), 96-107. https://doi.org/10.21068/c2021.v22n01a06

Anthropogenic noise, which is part of an urban soundscape, can negatively affect the behaviour of wild animals. Here we investigated how biophony (animal sounds) was affected by noise in an urban Brazilian forest frag-ment. Our hypothesis was that no...
