A test of the Acoustic Adaptation Hypothesis in three types of tropical forest: degradation of male and female Rufous-and-white Wren songs
(2016)
Many animals produce complex vocalizations that show pronounced variation between populations. The Acoustic Adaptation Hypothesis helps to explain this variation, suggesting that acoustic signals are optimized for transmission ...
Reduced geographic variation in roars in different habitats rejects the acoustic adaptation hypothesis in the black-and-gold howler monkey (Alouatta caraya)
(Wiley Blackwell Publishing, Inc, 2019-10)
Vocalizations used for long‐range communication must disperse without significant structural changes to be decoded by receivers. The acoustic adaptation hypothesis (AAH) holds that, since acoustic signals are influenced ...
Call Transmission Efficiency in Native and Invasive Anurans: Competing Hypotheses of Divergence in Acoustic Signals
(2013)
Invasive species are a leading cause of the current biodiversity decline, and hence examining the major traits
favouring invasion is a key and long-standing goal of invasion biology. Despite the prominent role of ...
The acoustic adaptation hypothesis in a widely distributed South American frog: Southernmost signals propagate better
(Nature Publishing Group, 2018)
© 2018 The Author(s).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 advertisement calls of male ...

Transmission characteristics of solo songs and duets in a neotropical thicket habitat specialist bird
(2015-09-22)
The Acoustic Adaptation Hypothesis posits that habitat characteristics influence the structure of animal vocalizations and that animals will vocalize and display behaviours optimized for sound transmission. White-eared ...
Contrasting Propagation of Natural Calls of Two Anuran Species from the South American Temperate Forest
(Public Library Science, 2015)
The acoustic adaptation hypothesis predicts that sound communication signals have an optimal relationship with animals' native environments. However, species sharing a habitat produce signals stratified in the spectral ...
