Wind farm noise negatively impacts the calling behavior of three frogs in Caatinga dry forests.

ABSTRACT: Acoustic signals play a fundamental role in the lives of anurans. With the increasing prevalence of wind farms in Caatinga ecosystems, our goal was to assess whether the noise generated by this energy source poses a threat to anuran communication. We analyzed acoustic parameters of the advertisement calls from 181 adult males, of the species Scinax pachycrus, Scinax x-signatus, and Physalaemus cicada. Call activity was recorded across noise gradients in 19 temporary ponds with similar vegetation structures, distributed in two wind farms. Our results revealed a significant relationship between wind turbine noise and changes in acoustic parameters of the three species, distinctly influencing their spectral and temporal parameters of the advertisement calls.
