The acoustic adaptation hypothesis in a widely distributed South American frog: Southernmost signals propagate better

NA Velásquez, FN Moreno-Gómez, E Brunetti… - Scientific Reports, 2018 - nature.com
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

M Ringler, G Szipl, W Hödl, L Khil, B Kofler… - Behavioral Ecology and …, 2017 - Springer
Acoustic ranging allows identifying the distance of a sound source and mediates inter-

Amplification of frog calls by reflective leaf substrates: implications for terrestrial and arboreal species

MI Muñoz, W Halfwerk - Bioacoustics, 2022 - Taylor & Francis
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

MI Muñoz, M Quispe, M Maliqueo, M Penna - Hormones and Behavior, 2020 - Elsevier
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
