| the influence of riverine barriers on phylogeographic patterns of malagasy reed frogs (heterixalus). | we analyzed the influence of large rivers on the phylogeography of endemic widespread amphibians along madagascar's east coast, using as models various species and species complexes of malagasy reed frogs (heterixalus spp.) that are specialized to either highland or lowland habitats. we assembled a dense sampling across the full species ranges and used mitochondrial (cob) as well as nuclear (rag-1) dna sequences to assess their phylogeographies. a multigene mtdna phylogeny of each species was co ... | 2012 | 22659515 |
