The allopatric model of biological speciation involves fracturing of a pre-existing species
distribution and subsequent genetic divergence in isolation. Accumulating global evidence …

Testing hypotheses on drivers of clade evolution and trait diversification provides insight into
many aspects of evolutionary biology. Often, studies investigate only intrinsic biological …

In this contribution, the aspects of reptile and amphibian speciation that emerged from
research performed over the past decade are reviewed. First, this study assesses how …

Understanding the factors that cause heterogeneity among gene trees can increase the
accuracy of species trees. Discordant signals across the genome are commonly produced …

Background Phylogeographic research has advanced in South America, with increasing
efforts on taxa from the dry diagonal biomes. However, the diversification of endemic fauna …

We update the list of lizards of Argentina, reporting a total of 261 species from the country,
arranged in 27 genera and 10 families. Introduced species and dubious or erroneous …

In this study we detangled the evolutionary history of the Patagonian lizard clade Liolaemus
kingii, coupling dense geographic sampling and novel computational analytical approaches …

Species delimitation studies based on integrative taxonomic approaches have received
considerable attention in the last few years, and have provided the strongest hypotheses of …

In the last years, different spatial analyses were developed to support multi-taxon
biodiversity conservation strategies. In fact, the use of species distribution models as input …

The lizard genus L iolaemus and different clades within it have been the focus of several
recent phylogenetic studies mainly based on morphology and mt DNA. Although there is …
