In this study we evaluated if geographic song variation of wedge-tailed sabrewings (Campylopterus curvipennis) is correlated with genetic divergence, and examined processes that explain best the origin of intraspecific song variation. We contrasted estimates of genetic differentiation, genetic structure, and gene flow across leks from microsatellite loci of wedge-tailed sabrewings with measures for acoustic signals involved in mating derived from recordings of males singing at leks throughout eastern Mexico. We found a strong acoustic structure across leks and geography, where lek members had an exclusive assemblage of syllable types, differed in spectral and temporal measurements of song, and song sharing decreased with geographic distance. However, neutral genetic and song divergence were not correlated, and measures of genetic differentiation and migration estimates indicated gene flow across leks. The persistence of acoustic structuring in wedge-tailed sabrewings may thus best be explained by stochastic processes across leks, in which intraspecific vocal variation is maintained in the absence of genetic differentiation by postdispersal learning and social conditions, and by geographical isolation due to the accumulation of small differences, producing most dramatic changes between populations further apart.", "link"=>"http://www.mendeley.com/research/acoustic-divergence-gene-flow-lekking-hummingbird-complex-songs", "reader_count"=>49, "reader_count_by_academic_status"=>{"Unspecified"=>2, "Librarian"=>1, "Researcher"=>4, "Student > Doctoral Student"=>4, "Student > Ph.

We found a strong acoustic structure across leks and geography, where lek members had an exclusive assemblage of syllable types, differed in spectral and temporal measurements of song, and song sharing decreased with geographic distance. However, neutral genetic and song divergence were not correlated, and measures of genetic differentiation and migration estimates indicated gene flow across leks. The persistence of acoustic structuring in wedge-tailed sabrewings may thus best be explained by stochastic processes across leks, in which intraspecific vocal variation is maintained in the absence of genetic differentiation by postdispersal learning and social conditions, and by geographical isolation due to the accumulation of small differences, producing most dramatic changes between populations further apart.</p></div>", "links"=>[], "tags"=>["intraspecific song variation", "differentiation", "sabrewing", "Complex Songs Hummingbirds", "lek", "Gene flow"], "article_id"=>1189782, "categories"=>["Biological Sciences", "Science Policy"], "users"=>["Clementina González", "Juan Francisco Ornelas"], "doi"=>["https://dx.doi.org/10.1371/journal.pone.0109241.s001", "https://dx.doi.org/10.1371/journal.pone.0109241.s002", "https://dx.doi.org/10.1371/journal.pone.0109241.s003", "https://dx.doi.org/10.1371/journal.pone.0109241.s004", "https://dx.doi.org/10.1371/journal.pone.0109241.s005", "https://dx.doi.org/10.1371/journal.pone.0109241.s006", "https://dx.doi.org/10.1371/journal.pone.0109241.s007", "https://dx.doi.org/10.1371/journal.pone.0109241.s008", "https://dx.doi.org/10.1371/journal.pone.0109241.s009", "https://dx.doi.org/10.1371/journal.pone.0109241.s010", "https://dx.doi.org/10.1371/journal.pone.0109241.s011", "https://dx.doi.org/10.1371/journal.pone.0109241.s012", "https://dx.doi.org/10.1371/journal.pone.0109241.s013"], "stats"=>{"downloads"=>31, "page_views"=>28, "likes"=>0}, "figshare_url"=>"https://figshare.com/articles/_Acoustic_Divergence_with_Gene_Flow_in_a_Lekking_Hummingbird_with_Complex_Songs_/1189782", "title"=>"Acoustic Divergence with Gene Flow in a Lekking Hummingbird with Complex Songs", "pos_in_sequence"=>0, "defined_type"=>4, "published_date"=>"2014-10-01 03:02:46"}
