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.


We genotyped 1056 individuals of two anuran and three urodele species (1732–3913 SNPs per species) from populations located in a landscape comprising 64 ponds to characterize fine-scale genetic structure in a comparative framework, and combined these genetic data with information obtained in a previous 2-year capture–mark–recapture (CMR) study.
