Can two acoustically communicating species using very similar call structures co-exist and if so, what are the proximate mechanisms they can use to prevent interference between species
Answers
Explanation:
Studies of vocal behavior in anurans provide significant insights about the mechanisms and evolution of animal communication. Females extract the information required for a mating decision from relatively stereotyped advertisement calls that are produced by males. Aggressive signals, used in exchanges between males, are more variable in form, as might be expected of communication between rivals, but overall, their structure is more similar in closely related species than is that of advertisement calls. One open question is why, within the groups of treefrogs considered in this review, aggressive signaling is so prevalent in some species and rare or absent in close relatives.
