In the coqui frog (\n                    <jats:italic>Eleutherodactylus coqui<\/jats:italic>\n                    ), it is known that the spectral contents of its calls systematically change with altitude above sea level. Here, distortion product otoacoustic emissions are used to assess the frequency range over which the inner ear is sensitive. It is found that both the spectral contents of the calls and the inner-ear sensitivity change in a similar fashion along an altitudinal gradient. As a result, the call frequencies and the auditory tuning are closely matched at all altitudes. We suggest that the animal's body size determines the frequency particulars of the call apparatus and the inner ear.\n                  <\/jats:p>","DOI":"10.1098\/rsbl.2009.0763","type":"journal-article","created":{"date-parts":[[2009,11,25]],"date-time":"2009-11-25T23:42:00Z","timestamp":1259192520000},"page":"278-281","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":27,"title":["Frequency matching of vocalizations to inner-ear sensitivity along an altitudinal gradient in the coqui frog"],"prefix":"10.1098","volume":"6","author":[{"given":"Sebastiaan W.
