Driving Factors for the Evolution of Species-Specific Echolocation Call Design in New World Free-Tailed Bats (Molossidae) [PDF]
PLoS ONE, 2014 Phylogeny, ecology, and sensorial constraints are thought to be the most important factors influencing echolocation call design in bats. The Molossidae is a diverse bat family with a majority of species restricted to tropical and subtropical regions ...

High duty cycle to low duty cycle: echolocation behaviour of the hipposiderid bat Coelops frithii. [PDF]
PLoS ONE, 2013 Laryngeally echolocating bats avoid self-deafening (forward masking) by separating pulse and echo either in time using low duty cycle (LDC) echolocation, or in frequency using high duty cycle (HDC) echolocation. HDC echolocators are specialized to detect

Correlated evolution of wing morphology and echolocation calls in bats
Frontiers in Ecology and Evolution, 2022 IntroductionFlight and echolocation are two crucial behaviors associated with niche expansion in bats. Previous researches have attempted to explain the interspecific divergence in flight morphology and echolocation vocalizations in some bat groups from ...

Different auditory feedback control for echolocation and communication in horseshoe bats. [PDF]
PLoS ONE, 2013 Auditory feedback from the animal's own voice is essential during bat echolocation: to optimize signal detection, bats continuously adjust various call parameters in response to changing echo signals.
