Urban noise adaptation can disrupt mating rhythms and increase predation risk

Evidence

Urban noise offers a unique opportunity for great experimentation on how a signal changes under the pressure of such a dynamic sonic environment. Urban means heterogeneous in space and time for the distribution of houses, roads, gardens, parks, etc. This heterogeneity is found also in the soundscape, which creates new conditions in which species can evolve and adapt coping cultural and genetic mechanisms. The adaptation of species to the urban environment can suffer physiological constraints such as the impossibility of changing the frequency or suffering from the shift in acoustic rhythms to escape the masking effect of noise. These adaptations simultaneously could produce desynchronization of mating or increased exposure to predators. — Almo Farina, Soundscape Ecology, 1502
