Erosion of Lizard Diversity by Climate Change and Altered Thermal Niches
Global extinction projections were validated with local extinctions observed from 1975 to 2009 for regional biotas on four other continents, suggesting that lizards have already crossed a threshold for extinctions caused by climate change. Expand
Mitochondrial DNA Sequence Divergence and Phylogenetic Relationships among Eight Chromosome Races of the Sceloporus Grammicus Complex (Phrynosomatidae) in Central Mexico
A single most-parsimonious tree was selected from among these on the basis of a new character-weighting method that takes into account the observed frequencies of all 12 possible substitutions for protein genes. Expand
Revisiting the historical distribution of Seasonally Dry Tropical Forests: new insights based on palaeodistribution modelling and palynological evidencegeb
Aim  To investigate the potential distribution of Seasonally Dry Tropical Forests (SDTFs) during the Quaternary climatic fluctuations; to reassess the formerly proposed ‘Pleistocenic arc hypothesis’Expand
Phylogenetic relationships and limb loss in sub-Saharan African scincine lizards (Squamata: Scincidae).
Reconstructions of ancestral states for limb and digital characters show limited support for the reversal or gain of both digits and limbs, but conservative interpretation of the results suggest that limb loss is common, occurring multiple times throughout evolutionary history, and is most likely not reversible. Expand
Delimiting species: a Renaissance issue in systematic biology
Nine methods for delimiting species boundaries are reviewed by summarizing the relevant biological properties of species amenable to empirical evaluation, the classes of data required and some of the strengths and limitations of each. Expand
Resolving the phylogeny of lizards and snakes (Squamata) with extensive sampling of genes and species
Higher-level squamate phylogeny is analysed with a molecular dataset of unprecedented size, including 161 squamate species for up to 44 nuclear genes each (33 717 base pairs), using both concatenated and species-tree methods for the first time, and it is found that dibamids and gekkotans are together the sister group to all other squamates. Expand
Phylogeny of iguanian lizards inferred from 29 nuclear loci, and a comparison of concatenated and species-tree approaches for an ancient, rapid radiation.
The phylogenetic results suggest a non-traditional biogeographic scenario in which pleurodonts originated in the Northern Hemisphere and subsequently spread southward into South America. Expand
Around the world in 10 million years: biogeography of the nearly cosmopolitan true toads (Anura: Bufonidae)
The origin of the enigmatic Caribbean lineage was found to be consistent with colonization following the bolide impact at the K/T boundary, providing the first, firm foundation for understanding true toad divergence times and their truly remarkable and global radiation. Expand
A molecular perspective on the evolution of microteiid lizards (Squamata, Gymnophthalmidae), and a new classification for the family
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
Emerging phylogeographical patterns of plants and terrestrial vertebrates from Patagonia
This review reveals some congruent phylogeographical patterns within and among plants and terrestrial vertebrates, and suggests that Pre-Quaternary as well as Quaternary geological events would have been important driving forces in the evolutionary history of Patagonian lineages. Expand
