Complex patterns of diversification in the gray zone of speciation: Model-based approaches applied to Patagonian liolaemid lizards (Squamata: Liolaemus kingii clade)
<p>In this study, we detangled the evolutionary history of the Patagonian lizard clade <em>Liolaemus kingii</em>, coupling dense geographic sampling and novel computational analytical approaches. We analyzed nuclear and mitochondrial data (restriction DNA sequencing and cytochrome <em>b</em>) to hypothesize and evaluate species limits, phylogenetic relationships, and demographic histories. We also conducted posterior predictive simulations to assess the fit of the genomic data to the multispecies coalescent model. Our results show several instances of mito-nuclear discordance and consistent support for a reticulated history, supporting the view that the complex evolutionary history of the <em>kingii</em> clade is characterized by extensive gene flow and rapid diversification events. We discuss our findings in the contexts of the "gray zone" of speciation, phylogeographic patterns in the Patagonian region, and taxonomic outcomes.</p>

Data from: Elevational Goldilocks zone underlies the exceptional diversity of an Andean lizard radiation (Liolaemus; Liolaemidae)
<p>Mountains are among the most biodiverse regions on the planet, and how these landforms shape diversification through the interaction of biological traits and geo-climatic dynamics is integral to understanding global biodiversity. In this study we investigate the dual roles of climate change and mountain uplift on the evolution of a hyper diverse radiation, <em>Liolaemus </em>lizards, with a spatially explicit model of diversification using a reconstruction of uplift and paleotemperature in central and southern South America. The diversification model captures a hotspot for <em>Liolaemus </em>around 40°S in lineages with low dispersal ability and narrow niche breadths. Under the model, speciation rates are highest in low latitudes (<35°S) and mid-elevations (~1000m), while extinction rates are highest at higher latitudes (>35°S) and higher elevations (>2000m). Temperature change through the Cenozoic explained variation in speciation and extinction rates through time and across different elevational bands. Our results point to the conditions of mid-elevations being optimal for diversification (i.e., Goldilocks Zone), driven by the combination of (1) a complex topography which facilitates speciation during periods of climatic change, and (2) a relatively moderate climate which enables the persistence of ectothermic lineages and buffers species from extinction.</p>
