Call-type combinations of vocal interactions changed within pairs and were associated with successful egg-laying, highlighting a potential fitness relevance of calling dynamics in communication systems.
To our knowledge, ours is the first study to demonstrate an association between intra-pair calling dynamics and successful egg-laying, thus highlighting the potential fitness relevance of calls and calling interactions in communication systems.
Donald Griffin, who discovered echolocation in bats and pioneered much of its scientific understanding, early on pointed out the ecological relevance of echolocation call intensities [13], but only recently a handful of studies started to accumulate knowledge on call intensity for free flying bats in the field [3], [5], [14], [15], [16].
The present study gives the first account of the relevance of communication calls for species recognition and discrimination in cryptic primates in an area of sympatry combining a call structure analysis and playback experiments.
Attorneys spent the first hour on Tuesday arguing over the relevance of the calls, with prosecutor Richard Mantei suggesting they helped explain Zimmerman's frustration on the night of his confrontation with Martin when he told a police dispatcher: "These assholes, they always get away".
The relevance of genotypes called by ALG has been shown in a recent replication study [19].
Our results provide the first evidence for a specific relevance of social calls for speciation in cryptic primates.
In elephants, little is known about the functional relevance of male calls, which males produce more frequently during musth periods [ 27].
Playback experiments furthermore suggest a different relevance of heterospecific advertisement calls with regard to sympatry or allopatry as sympatric calls evoked lower responses than allopatric calls.
This is the new public school evangelism: a call for the relevance of the word, a call to bring the school to the street, and to drive the street right through the school.
