Stability Predicts Genetic Diversity in the Brazilian Atlantic Forest Hotspot
TLDR
It is shown that the southern Atlantic forest was climatically unstable relative to the central region, which served as a large climatic refugium for neotropical species in the late Pleistocene, and establishes a validated approach to biodiversity prediction in other understudied, species-rich regions. Expand
Phylogeography and species limits in the Gymnodactylus darwinii complex (Gekkonidae, Squamata): genetic structure coincides with river systems in the Brazilian Atlantic Forest
TLDR
A hypothesis of species limits for G. darwinii is presented, based on concordant lines of evidence including cytogenetic and mtDNA analyses, and two chromosome races are interpreted to be full species on the basis of a number of empirical criteria. Expand
DEEP DIVERSIFICATION AND LONG‐TERM PERSISTENCE IN THE SOUTH AMERICAN ‘DRY DIAGONAL’: INTEGRATING CONTINENT‐WIDE PHYLOGEOGRAPHY AND DISTRIBUTION MODELING OF GECKOS
TLDR
These patterns exemplify how low‐vagility species complexes, characterized by strong genetic structure and pre‐Pleistocene divergence histories, represent ideal radiations to investigate broad biogeographic histories of associated biomes. Expand
Phylogenetics of the lizard genus Tropidurus (Squamata: Tropiduridae: Tropidurinae): direct optimization, descriptive efficiency, and sensitivity analysis of congruence between molecular data and
TLDR
A sensitivity analysis demonstrated that equal weighting of indels, transitions, transversions, and morphological change provided the most congruent solution between the molecular and the morphological data partitions. Expand
A molecular perspective on the evolution of microteiid lizards (Squamata, Gymnophthalmidae), and a new classification for the family
TLDR
The total molecular evidence provided a better-resolved hypothesis than did separate analysis of individual partitions, and the PBS analysis indicates congruence among independent partitions for support of some internal nodes. Expand
Lizards, Snakes, and Amphisbaenians from the Quaternary Sand Dunes of the Middle Rio Sao Francisco, Bahia, Brazil
TLDR
A Quaternary sand dune area was discovered in the morphoclimatic domain of the semiarid Brazilian Caatinga, containing a very unique fauna presenting striking adaptations to psammophily and high levels of species richness and endemism. Expand
Molecular systematics of teioid lizards (Teioidea/Gymnophthalmoidea: Squamata) based on the analysis of 48 loci under tree‐alignment and similarity‐alignment
TLDR
Comparisons of tree costs suggest that the pattern of indels inferred by similarity‐alignment drove parsimony analyses on similarity‐aligned sequences away from more optimal solutions, suggesting that neither the criterion of optimality, alignment nor treatment of indel alone can explain all differences. Expand
Comparing alignment methods for inferring the history of the new world lizard genus Mabuya (Squamata: Scincidae).
TLDR
This paper uses a diverse sampling of gene regions from lizards of the genus Mabuya to compare the impact of new maximum likelihood alignment algorithms with more widely used methods, and shows that the consistent use of model-based methods in both alignment and tree reconstruction leads to trees with more optimal likelihood scores. Expand
Prediction of phylogeographic endemism in an environmentally complex biome
TLDR
It is suggested that climatic variability through the last 250 kyr impacted the northern and the southern forests differently, and sub-regional differences in climate dynamics will enhance the ability to understand those processes shaping high phylogeographic and species endemism, in the Neotropics and beyond. Expand
