Effects of a Riverine Dispersal Barrier on Cultural Similarity in Wild Bornean Orangutans (Pongo Pygmaeus Wurmbii)
… from Sungai Lading by an impassable river barrier, but ranging in a broadly similar habitat. Preliminary genetics results indicate that at least some individuals from both sites cluster in the same mitochondrial subclade and that low levels of gene flow must have occurred between the two …

Phylogenetic Niche Modeling
… factors--including biotic interactions and dispersal barrier—truncating SDM estimates. Though truncated SDMs may accurately predict present-day species niche, projections through time are often biased by environmental condition change. Modeling niche in a phylogenetic framework leverages a …

Status, Distribution and Biogeography of the Birds of Paraguay
… Orient, appears to be the most effective barrier to bird dispersal in Paraguay. There is little evidence that the relatively broad Paraguay River is an effective dispersal barrier. The Pilcomayo River likely formed a forest bridge between Yungas and Paranense forests.during more humid …

Biodiversity and Biogeography of Amphipod Crustaceans
… Line as a biogeographic boundary for species dispersal. Five groups of benthic amphipod crustaceans were found. These groups showed no resemblance to Wallace’s faunal division but did show relationships with sampling methods, depth, and substrata. There was only one biogeographic region …
