This COI barcoding library provides an almost complete and reliable reference library for Western Palearctic amphibians. We highlight the importance of generating comprehensive and well curated reference libraries that include intra- and interspecific genetic variability and the need of detailed taxonomic revision when ambiguous or incorrect DNA barcodes exist.

Remarkably, we highlight striking discordances between mitochondrial and nuclear distributions across their hybrid zones, as well as between their genetic and morphological differentiation. Our study illustrates how genomic-based phylogeographic frameworks can help decipher the high genetic and phenotypic variation of species complexes and substantiate the taxonomic assessment of candidate lineages.

The changes observed may have been caused by release of salamander larvae predatory pressure on invertebrates, which could have promoted their grazing on periphyton, in contrast to their preference for leaf shredding in the presence of salamander. Our study demonstrates an important role of salamander larvae in montane streams through top-down control of lower trophic levels and thus in regulating key stream ecosystem processes.  Leer más.
