Calling songs were recorded from 13 sympatric and allopatric localities. Both field and laboratory recordings showed that chirp rate (CR) and pulse rate (PR) overlapped extensively between allopatric populations of G. fultoni and sympatric populations of G. vernalis; by contrast, there was little or no overlap in these variables between sympatric populations of these two species. Divergence in PR and CR between the two species was thus greater in areas of sympatry than in areas of allopatry. Our field and laboratory studies of G. fultoni calling songs thus demonstrate the pattern expected of character displacement and support the genetic assumptions of this hypothesis. Other possible explanations for the sympatric divergence such as ecological character displacement and clinal variation are discussed.</jats:p>","journal":"Journal of Evolutionary Biology","year":2006,"id":36779,"datarank":2.3450695386657436,"base_score":4.189654742026425,"endowment":4.189654742026425,"self_citation_contribution":0.6284482113039639,"citation_network_contribution":1.7166213273617796,"self_endowment_contribution":0.6284482113039639,"citer_contribution":1.7166213273617796,"corpus_percentile":null,"corpus_rank":null,"citation_count":65,"citer_count":55,"citers_with_citation_signal":51,"citers_with_endowment":51,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":null,"is_data_producer":false,"deposit_databanks":null,"is_oa":false,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":null,"fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":185644,"name":"H.
