Nonoptimal propagation of advertisement calls of midwife toads in Iberian habitats
(2006)
This study compares the efficiency of transmission of the advertisement calls of two species of midwife toads, Alytes cisternasii and A. obstetricans, in both native and non-native habitats in the Iberian Peninsula. Recorded ...
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 ...
The role of habituation in the adjustment to urban life: An experimental approach with burrowing owls
(Elsevier Science, 2018-12)
Birds exhibit variation in fear behaviour in response to an approaching human within and between species and across different habitat contexts. We analyze urban and rural burrowing owls’ variation in risk perception along ...
Differing nest-defence behaviour in urban and rural populations of breeding Burrowing Owls
(Csiro Publishing, 2016-04)
The behaviour of birds in urban habitats often differs from that of birds in surrounding natural and rural habitats, with the attenuation of fear responses to humans a primary behavioural adaptation to urban life. In ...
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 ...
Variation in echolocation call frequencies in two species of free-tailed bats according to temperature and humidity
(2017)
Bats can actively adjust their echolocation signals to specific habitats and tasks, yet it is not known if bats also modify their calls to decrease atmospheric attenuation. Here the authors test the hypothesis that individuals ...
