Call attenuation data of three frog species in tree plantations and a native forest in southern Brazil

Call transmission is influenced by the acoustics of the propagation
environment, including vegetation. Thus, forestry monocultures of
non-native trees represent artificial environments that could modify call
transmission. These monocultures have substituted large areas of the
Atlantic Forest in southern Brazil, representing a conservation challenge.
Considering this context, we hypothesized that anurans have calls less
attenuated in their native environment than in forest plantations. To test
it, we performed sound transmission experiments using calls of three
anuran species native to southern Brazil: Boana bischoffi, B.
leptolineata, and Hylodes meridionalis. We compared sound attenuation
between the native forest and forestry monocultures (Eucalyptus sp. and
Pinus sp. forests), and included distance from the sound source, air
temperature, humidity, and vegetation density as co-factors in linear
mixed models.
