The acoustic adaptation hypothesis in a widely distributed South American frog: Southernmost signals propagate better
Animal communication occurs in environments that affect the properties of signals as they
propagate from senders to receivers. We studied the geographic variation of the …

Acoustic ranging in poison frogs—it is not about signal amplitude alone
Acoustic ranging allows identifying the distance of a sound source and mediates inter-
individual spacing and aggression in territorial species. Birds and mammals are known to …

Transmission of high-frequency vocalizations from hummingbirds living in diverse habitats
Some species of Andean hummingbirds produce high-frequency vocalizations which
exceed the vocal range of most birds. They also challenge our understanding of the role of …

Amplification of frog calls by reflective leaf substrates: implications for terrestrial and arboreal species
Signal detection is a fundamental requirement for any communicative interaction. Acoustic
signals, however, experience amplitude losses during their transmission through the …

Biotic and abiotic sounds affect calling activity but not plasma testosterone levels in male frogs (Batrachyla taeniata) in the field and in captivity
In animals, the expression of diverse reproductive behaviors is hormonally regulated. In
particular, vocalizing during courtship has been related to circulating androgen levels, and …

Evolution of High-Frequency Vocalizations in Hummingbirds
F Duque Mendoza - 2021 - scholarworks.gsu.edu
While most birds sing and hear between 2–6 kHz, four Andean hummingbirds vocalize
between 9–16 kHz. This phenomenon provides an opportunity to investigate the evolution of …
