In this work, we aimed to explore the effect of geographic barriers on the distribution of the phenotypic and genetic variation of a spider species that is widespread in continental and insular America. We obtained an alignment of the mitochondrial locus Cytochrome Oxidase I (COI) for 408 individuals across the geographic range of <i>Gasteracantha cancriformis</i>. We used phylogenetics, population genetics, and morphology to explore the genetic and phenotypic variation of this species. We found five genetically differentiated and geographically structured populations. Three of them are distributed in continental America, separated by the Andes mountains, and two are in the Caribbean and Galapagos Islands. Some of these geographic clades shared haplotypes between them, which may be a consequence of dispersal. We detected at least 20 phenotypes of <i>G. cancriformis</i>, some of which were exclusive to a geographic region, while others occurred in multiple regions. We did not observe well-defined morphological differences across male genitalia. This evidence suggests that <i>G. cancriformis</i> is a widespread species with high phenotypic variation that should be explored in more depth.</p>\u0000 </div>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":"2022 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2022-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2022/8112945","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49215415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous phylogenetic work on the palm rocket frog (Anura: Aromobatidae: <i>Rheobates</i> spp.), endemic to midelevation forests of Colombia, suggested that valleys were important in promoting divergence between lineages. In this study, we first evaluated previous hypotheses of species-level diversity, then fitted an isolation-with-migration (IM) historical demographic model, and tested two landscape genetic models to explain genetic divergence within <i>Rheobates</i>: isolation by distance and isolation by environment. The data consisted of two mitochondrial and four nuclear genes from 24 samples covering most of the geographic range of the genus. Species delimitation by Bayesian Phylogenetics and Phylogeography recovered five highly divergent genetic lineages within <i>Rheobates</i>, among which few to no migrants are exchanged according to IM. We found that isolation by environment provided the only variable significantly correlated with genetic distances for both mitochondrial and nuclear genes, suggesting that local adaptation may have a role in driving the genetic divergence within this frog genus. Thus, genetic divergence in <i>Rheobates</i> may be driven more by variation among the local environments where these frogs live rather than by geographic distance.</p>\u0000 </div>","PeriodicalId":54751,"journal":{"name":"Journal of Zoological Systematics and Evolutionary Research","volume":"2022 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2022-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2022/6774225","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45230656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
