We measured auditory brainstem responses from 12 bat species that make their living gleaning prey off surfaces in the rainforest understory. In the lower-frequency ranges, auditory sensitivity reflected the foraging demands of each species, many of which find prey by attending to prey-produced noises such as prey mating calls and prey locomotion sounds. Our results suggest that interspecific differences in hearing abilities and thus the differential ability to hear prey-produced sounds could be an important mechanism contributing to niche differentiation.<\/jats:p>","DOI":"10.1073\/pnas.2024943118","type":"journal-article","created":{"date-parts":[[2021,8,23]],"date-time":"2021-08-23T16:25:11Z","timestamp":1629735911000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":28,"title":["Hearing sensitivity: An underlying mechanism for niche differentiation in gleaning bats"],"prefix":"10.1073","volume":"118","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3118-2460","authenticated-orcid":false,"given":"Inga","family":"Geipel","sequence":"first","affiliation":[{"name":"Gamboa Bat Lab, Sensory and Cognitive Ecology, Smithsonian Tropical Research Institute, Apartado 0843-03092, Balboa, Panam\u00e1;"},{"name":"CoSys Lab, Faculty of Applied Engineering, University of Antwerp, 2020 Antwerp, Belgium;"},{"name":"Flanders Make Strategic Research Centre, 3920 Lommel, Belgium;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8928-8770","authenticated-orcid":false,"given":"Ella Z.","family":"Lattenkamp","sequence":"additional","affiliation":[{"name":"Neurogenetics of Vocal Communication Group, Max Planck Institute for Psycholinguistics, 6525 XD Nijmegen, The Netherlands;"},{"name":"Division of Neurobiology, Department of Biology II, Ludwig Maximilians University Munich, 82152 Martinsried, Germany;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.
