An important goal of evolutionary and conservation biology is the identification of units below the species level, such as Evolutionarily Significant Units (ESUs), providing objectively delimited units for species conservation and management. In this study we tested the hypothesis that Cuvier’s dwarf caiman (Paleosuchus palpebrosus)—a species broadly distributed across several biomes and watersheds...
Population persistence depends in many cases on gene flow between local populations. Parnassius apollo nevadensis is an endemic subspecies of Apollo butterfly in the Sierra Nevada (southern Spain), whose populations are distributed in discrete patches at altitudes between 1850 and 2700 m. In this paper, we use 13 microsatellite loci to examine the genetic structure of this P. apollo subspecies. We...
