Abstract Aim We investigate the spatiotemporal context of diversification Allobates , a widespread genus Amazonian frogs with high species diversity particularly in western Amazonia. tested if that originated situ or through repeated dispersals from other areas and this took place during after Pebas system, vast lacustrine system occupying most Amazonia between 23 10 million years ago (Mya). Location Taxon (Anura: Aromobatidae). Methods gathered spatially taxonomically extensive sampling mitochondrial DNA sequences 932 specimens to delimit Operational Taxonomic Units (OTUs). Complete mitogenomes these OTUs were assembled reconstruct time‐calibrated phylogeny used infer historical spatial origin lineages. Results Phylogenetic analyses ancestral area reconstruction suggested lineages resulted events occurred inferred (25 Mya) Mya, possible peak 14 Mya. Dispersal among mostly towards Brazilian Guiana Shields. Closely related display an allopatric pattern distribution, matching interfluves delimited by modern rivers. Main Conclusions In Amazonia, appears have been simultaneous last stages (14–10 Mya). Subsequently (within Mya), river courses shaped distribution possibly promoted speciation.

Riverine Barriers as Obstacles to Dispersal in Amazonian Birds

Amazonian rivers represent known barriers for avian dispersal, reducing gene flow and enhancing differentiation. Despite the importance of in evolutionary process, we have made only minor advances understanding limitations imposed by on flying birds. To fill that gap, conducted dispersal-challenge experiments over water, assessing capabilities 84 tropical bird species 22 different families. We mist-netted released 484 birds from a stationary boat Rio Branco, northern Amazonia, at increasing distances shore, including 249 individuals 100; 219 200; 8 300; 5 400 m. A successful trial was represented reaching riverbank, whereas failure would refer to not shore landing when they were rescued our team. Our main goal understand if outcome could be predicted (i) phylogenetic constraints, (ii) morphology (body mass wing shape), (iii) flight speed, (iv) ecological preferences (stratum, habitat, river-island specialization), (v) psychological reluctance fly.

Differences in Quaternary co-divergence reveals community-wide diversification in the mountains of southwest China varied among species

Proceedings of the Royal Society B Biological Sciences, Год журнала: 2021, Номер 288(1942), С. 20202567 - 20202567

The mountains of southwest China (MSWC) is a biodiversity hotspot with highly complex and unusual terrain. However, the majority studies focusing on biogeographic consequences massive mountain building, Quaternary legacy for MSWC has long been overlooked. Here, we took statistical comparative phylogeography approach to examine factors that shaped community-wide diversification. With data from 30 vertebrate species, results reveal spatially concordant genetic structure, temporally clustered co-divergence events associated river barriers during severe glacial cycles. This indicates importance riverine in phylogeographic history community. We conclude repeated cycles are co-divergences themselves structured by heterogeneity montane landscape MSWC. orderly process diversification profound implications conservation highlighting relative independence different geographical areas which some, but not all species communities have responded similarly climate change calls further investigations connection between biological traits divergence pulses this hotspot.

The outstanding species richness of Amazonia has fascinated biologists for centuries. However, the records actual numbers and distribution forming its ecosystems are so incomplete that understanding historical causes regional determinants this diversity remain speculative. Anuran clades have repeatedly been documented to harbour many unnamed in region, notably Boana albopunctata group. Considering ecology group, we hypothesized it diversified via successive trans-riverine dispersals during late Miocene Pliocene, after formation modern Amazon watershed. To test hypothesis, gathered an extensive dataset 16S rDNA sequences sampled throughout a mitogenomic representative clade (1) re-evaluate boundaries distributions, (2) infer spatio-temporal history diversification within Amazonia. We delimited 14 Operational Taxonomic Units (OTUs) Amazonian clade, i.e., 75% higher than currently recognized (14 OTUs eight described species). Combining molecular data with morphological acoustic data, two new species, courtoisae sp. nov. from eastern Guiana Shield eucharis Southern Amazonia, herein. These belong last 10 Ma, thus more recently co-distributed small terrestrial anurans but concomitantly other vagile vertebrates. Our time-scaled phylogeny biogeographic analyses suggest initial east-west divergence confirm reciprocal 5 Ma. geomorphological evolution region species-specific dispersal ability largely explain these distinct patterns across anurans.http://www.zoobank.org/zoobank.org:act:4F8ACA9F-F6F1-4605-BD6C-6D4650AACCBEhttp://www.zoobank.org/zoobank.org:act:51CC7B40-2D6B-4A9E-AF50-AB34D4CE1042

The role of biogeographical barriers on the historical dynamics of passerine birds with a circum‐Amazonian distribution

Ecology and Evolution, Год журнала: 2024, Номер 14(3)

Опубликована: Март 1, 2024

Abstract Common distributional patterns have provided the foundations of our knowledge Neotropical biogeography. A distinctive pattern is “circum‐Amazonian distribution”, which surrounds Amazonia across forested lowlands south and east basin, Andean foothills, Venezuelan Coastal Range, Tepuis. The underlying evolutionary biogeographical mechanisms responsible for this widespread avian distribution yet to be elucidated. Here, we test effects barriers in four species passerine family Thamnophilidae by performing comparative demographic analyses genome‐scale data. Specifically, used flanking regions ultraconserved estimate population historical parameters genealogical trees tested models reflecting contrasting scenarios explaining circum‐Amazonian distribution. We found that taxa with at least two main phylogeographical clusters: (1) Andes, often extending into Central America Tepuis; (2) remaining their These clusters are connected through corridors along Chaco–Cerrado southeastern Amazonia, allowing gene flow between eastern South American populations. Demographic histories consistent Pleistocene climatic fluctuations having a strong influence on diversification history taxa, Refugia played crucial role, enabling both phenotypic genetic differentiation, maintaining substantial interconnectedness keep considerable levels during different dry/cool warm/humid periods. Additionally, steep environmental gradients appear play critical role structure.
