Bowie","doi":"10.21425/fob.17.132679","DOIUrl":"https://doi.org/10.21425/fob.17.132679","url":null,"abstract":"Southern Africa boasts an extraordinary diversity of birds, posited to have at least in part been driven by a “species pump” model, facilitated by an intermittent arid corridor connecting it with northeast Africa. This arid corridor arose and disappeared in concert with Plio-Pleistocene climate fluctuations, providing a means for northern, primarily arid-adapted lineages, to disperse to and subsequently colonize Southern Africa. Here, we test this “species pump” at the intra-specific level. We focus on Cape Robin-chats (Cossypha caffra) which have disjunct resident populations in the forested mountains of East Africa and in the aridlands of Southern Africa. We use multi-locus data to estimate gene flow between these populations, model spatial connectivity across this region contemporaneously and over the past 120 thousand years, and test niche differentiation. We found evidence for highly asymmetric gene flow (north to south) among Cape Robin-chat populations, and niche differentiation coupled with an inferred niche-based environmental filter limiting gene flow from southern to northern populations. Habitat suitability supports the presence of an intermittent corridor stretching from the Horn of Africa to Southern Africa. We propose that a modified species pump incorporating niche divergence and subsequent dispersal limitation driven by environmental filters has contributed to population differentiation among northern and southern populations of Cape Robin-chats, and that this same mechanism over time may have contributed to the rich avifaunal diversity of Southern Africa.\u0000 Southern Africa has rich avifauna with high endemicity driven in part by in situ speciation.\u0000 Using a combination of genetic analyses, niche models, and dispersal models, we find support for an intermittent aridlands corridor between disjunct populations of Cape Robin-chats modulated by Plio-Pleistocene climatic oscillations.\u0000 This study shows niche divergence and asymmetric gene flow between southern and northern populations, providing a mechanism for population divergence.\u0000 This supports the existence of an aridlands species pump that drives population divergence and may have contributed to species diversification in the Southern Africa avifauna.","PeriodicalId":37788,"journal":{"name":"Frontiers of Biogeography","volume":"47 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141922729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Macroecological correlates of richness, body size, and species range size in terrestrial vertebrates across the world","authors":"Q. Guo, Hong Qian, Pengcheng Liu, Jian Zhang","doi":"10.21425/f5fbg61729","DOIUrl":"https://doi.org/10.21425/f5fbg61729","url":null,"abstract":"Species richness, body size, and range size are among key subjects in animal macroecology and biogeography. To date, the species richness–body size–range size nexus remains largely understudied at a global scale and for large taxonomic groups. Here we examine the relative role of species richness and body size in determining species range size among terrestrial vertebrates across spatial and taxonomic scales. We then test related hypotheses in the context of Rapoport’s rule, latitude, and climate variation. To do this, we used simultaneous autoregressive analysis and structural equation modeling to test for statistical relationships among species richness, body size, and range size for all terrestrial vertebrates and for each continent. We then investigated the relative contributions of richness, body size, latitude, climate variation, and their combinations in the variations in species range sizes. We found that species richness consistently shows strong negative correlations with range size at global, regional, and within-region levels, and for all terrestrial vertebrates, and for each of the four classes (i.e., birds, mammals, amphibians, and reptiles). The strength of the relationships increased with richness and with spatial and taxonomic scales. Globally, species richness explained more variation in species range size than did latitude and climates. Body size contributed significantly to the range sizes of all four classes but especially reptiles and amphibians. However, the relative contributions of these factors varied substantially among the continents and terrestrial vertebrate classes. Comparison with the findings of a previous study shows that there were also significant differences in regional patterns between terrestrial vertebrates and plants and the relative contributions of diversity vs. latitude. Our findings show clear relationships among species richness, body size, and range size, but the strength of the relationships varies among regions and taxonomic groups. In general, species richness could predict species range size better than body size, latitude, and climate. These results have important theoretical and applied implications.","PeriodicalId":37788,"journal":{"name":"Frontiers of Biogeography","volume":"41 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140527154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
