“…This pattern of speciation in the West Cerrado also was observed in other lizard groups; Teixeira et al. () showed that populations of Stenocercus from lowlands and high elevations show molecular divergences that are consistent with the timing of reported environmental shifts in this region as a result of Andean orogeny. Lowlands between the Andean foothills and the Brazilian shield underwent large‐scale landscape transformations between 11.8 and 8 myr, with shifts in the course and contacts of major rivers, marine incursions coming from both north and south, and the establishment and vanishing of large lacustrine or marine systems (Cook, Chao, & Beheregaray, ; Hernández et al., ; Hoorn, ; Lovejoy, Albert, & Crampton, ; Lundberg et al., ; Räsänen, Linna, Santos, & Negri, ).…”

The Gran Chaco dry forest ecoregion corresponds to the southern portion of the South America diagonal belt of open formations, being one of the most threatened subtropical woodland savannas in the world. The area is still poorly known biologically and has been suffering with impressively high forest cover loss in the last 10 years. Integrating morphological and molecular data, we detected and describe a cryptic new species of lizard genus Ameivula endemic from the eastern part of this ecoregion, the called Humid Chaco. Ameivula apipensis sp nov. is characterised by a whitish brown vertebral stripe in adults and juveniles, a lateral field without ocelli and with overlapping spot, presence of an interfrontoparietal scale in 46.2% of the specimens, 12–17 femoral pores, an hemipenis without lateral sac, five xiphisternal ribs, and by a combination of meristic features as confirmed by discriminant analysis. The new species was recovered sister to a clade from Western Cerrado in our analysis, the first phylogenetic hypothesis for the Ameivula and Glaucomastix genera based on 1977 base pairs of three mitochondrial (12S, 16S and cyt‐b) and one nuclear (c‐mos) genes, including all the recognised species at the moment. Maximum parsimony and Bayesian inference recovered the monophyly of Ameivula and Glaucomastix with strong support. Reinforcing previous studies, our results suggest the presence of additional cryptic species in Ameivula from the Western Cerrado.

“…Species diversification driven by the uplift of the Andes has been documented in several organisms including birds (Chaves, Pollinger, Smith, & LeBuhn, ; Fernandes, Wink, Sardelli, & Aleixo, ; Ribas, Moyle, Miyaki, & Cracraft, ), reptiles (Teixeira et al., ), amphibians (García‐R et al., ; Guarnizo, Amézquita, & Bermingham, ; Guarnizo et al., ), bees (Dick et al., ), and butterflies (Elias et al., ); however, the persistence of gene flow between populations separated by the Andes is far less known (Hoffmann & Baker, ; Miller et al., ; Oswald et al., ). Here, despite the vicariance associated with the Andean uplift that resulted in eEC and wEC Andean clades for G. cancriformis , we found individuals with shared ancestry between the main two geographic groups.…”

The Andean uplift has played a major role in shaping the current Neotropical biodiversity. However, in arthropods other than butterflies, little is known about how this geographic barrier has impacted species historical diversification. Here, we examined the phylogeography of the widespread color polymorphic spider Gasteracantha cancriformis to evaluate the effect of the northern Andean uplift on its divergence and assess whether its diversification occurred in the presence of gene flow. We inferred phylogenetic relationships and divergence times in G. cancriformis using mitochondrial and nuclear data from 105 individuals in northern South America. Genetic diversity, divergence, and population structure were quantified. We also compared multiple demographic scenarios for this species using a model‐based approach (phrapl) to determine divergence with or without gene flow. At last, we evaluated the association between genetic variation and color polymorphism. Both nuclear and mitochondrial data supported two well‐differentiated clades, which correspond to populations occurring on opposite sides of the Eastern cordillera of the Colombian Andes. The final uplift of this cordillera was identified as the most likely force that shaped the diversification of G. cancriformis in northern South America, resulting in a cis‐ and trans‐Andean phylogeographic structure for the species. We also found shared genetic variation between the cis‐ and trans‐Andean clades, which is better explained by a scenario of historical divergence in the face of gene flow. This has been likely facilitated by the presence of low‐elevation passes across the Eastern Colombian cordillera. Our work constitutes the first example in which the Andean uplift coupled with gene flow influenced the evolutionary history of an arachnid lineage.

“…Therefore, these organisms represent an appropriate system to examine signatures of local adaptation associated with species occurrence along environmental gradients on the basis of GEAA. However, the role of genotypes that confer adaptation in shaping the distribution of tropical species remains underexplored (Damasceno, Strangas, Carnaval, Rodrigues, & Moritz, ; Moritz, Patton, Schneider, & Smith, ; Teixeira, ).…”

Environmental gradients constrain physiological performance and thus species’ ranges, suggesting that species occurrence in diverse environments may be associated with local adaptation. Genome–environment association analyses (GEAA) have become central for studies of local adaptation, yet they are sensitive to the spatial orientation of historical range expansions relative to landscape gradients. To test whether potentially adaptive genotypes occur in varied climates in wide‐ranged species, we implemented GEAA on the basis of genomewide data from the anole lizards Anolis ortonii and Anolis punctatus, which expanded from Amazonia, presently dominated by warm and wet settings, into the cooler and less rainy Atlantic Forest. To examine whether local adaptation has been constrained by population structure and history, we estimated effective population sizes, divergence times, and gene flow under a coalescent framework. In both species, divergence between Amazonian and Atlantic Forest populations dates back to the mid‐Pleistocene, with subsequent gene flow. We recovered eleven candidate genes involved with metabolism, immunity, development, and cell signaling in A. punctatus and found no loci whose frequency is associated with environmental gradients in A. ortonii. Distinct signatures of adaptation between these species are not associated with historical constraints or distinct climatic space occupancies. Similar patterns of spatial structure between selected and neutral SNPs along the climatic gradient, as supported by patterns of genetic clustering in A. punctatus, may have led to conservative GEAA performance. This study illustrates how tests of local adaptation can benefit from knowledge about species histories to support hypothesis formulation, sampling design, and landscape gradient characterization.
