Functional differences in echolocation call design in an adaptive radiation of bats
Ecology and Evolution, 2021 All organisms have specialized systems to sense their environment. Most bat species use echolocation for navigation and foraging, but which and how ecological factors shaped echolocation call diversity remains unclear for the most diverse clades ...

PLoS ONE, 2018 Acoustic communication plays a pivotal role in conspecific recognition in numerous animal taxa. Vocalizations must therefore have discrete acoustic signatures to facilitate intra-specific communication and to avoid misidentification.

Echolocation may have real-life advantages for blind people: an analysis of survey data
Frontiers in Physiology, 2013 Some people can echolocate by making sonar emissions (e.g. mouth-clicks, finger snaps, feet shuffling, humming, cane tapping, etc.) and listening to the returning echoes.

BMC Biology, 2005 Background Echolocating bats emit vocalizations that can be classified either as echolocation calls or communication calls. Neural control of both types of calls must govern the same pool of motoneurons responsible for vocalizations.

People's Ability to Detect Objects Using Click-Based Echolocation: A Direct Comparison between Mouth-Clicks and Clicks Made by a Loudspeaker. [PDF]
PLoS ONE, 2016 Echolocation is the ability to use reflected sound to obtain information about the spatial environment. Echolocation is an active process that requires both the production of the emission as well as the sensory processing of the resultant sound ...

General isochronous rhythm in echolocation calls and social vocalizations of the bat Saccopteryx bilineata [PDF]
Royal Society Open Science, 2019 Rhythm is an essential component of human speech and music but very little is known about its evolutionary origin and its distribution in animal vocalizations.

Unusual echolocation behaviour of the common sword-nosed bat Lonchorhina aurita: an adaptation to aerial insectivory in a phyllostomid bat? [PDF]
Royal Society Open Science, 2019 Most insectivorous bat species in the Neotropical family Phyllostomidae glean insects from ground, water or vegetation surfaces. They use similar and stereotypical echolocation calls that are generally very short (less than 1–3 ms), multi-harmonic and ...

Open‐source workflow approaches to passive acoustic monitoring of bats
Methods in Ecology and Evolution, 2023 The affordability, storage and power capacity of compact modern recording hardware have evolved passive acoustic monitoring (PAM) of animals and soundscapes into a non‐invasive, cost‐effective tool for research and ecological management particularly ...

Atmospheric humidity affects global variation of bat echolocation via indirect effects
Frontiers in Ecology and Evolution, 2022 The peak frequency of bat echolocation is a species-specific functional trait linked to foraging ecology. It is tailored via evolution to suit conditions within the distribution range of each species, but the evolutionary drivers are not yet well ...
