Using up to 2456 bp mtDNA and up to 2716 bp nDNA of fresh samples and short sequences of three mitochondrial genes of historical museum material, we examine the phylogeography of Amyda cartilaginea. This data set provides evidence for the existence of deeply divergent genetic lineages which we interpret as three distinct species, two of which are polytypic. Leer más.
Pluralistic approaches to taxonomy facilitate a more complete appraisal of biodiversity, especially the diversification of cryptic species. Although species delimitation has traditionally been based primarily on morphological differences, the integration of new methods allows diverse lines of evidence to solve the problem. Robber frogs (Pristimantis) are exemplary, as many of the species show high morphological variation within populations, but few traits that are diagnostic of species. Leer más.
