A phylogeny and revised classification of Squamata, including 4161 species of lizards and snakes
A new large-scale phylogeny of squamate reptiles is presented that includes new, resurrected, and modified subfamilies within gymnophthalmid and scincid lizards, and boid, colubrid, and lamprophiid snakes. Expand
A large-scale phylogeny of Amphibia including over 2800 species, and a revised classification of extant frogs, salamanders, and caecilians.
This study provides further evidence that the supermatrix approach provides an effective strategy for inferring large-scale phylogenies using the combined results of previous studies, despite many taxa having extensive missing data. Expand
Niche Conservatism: Integrating Evolution, Ecology, and Conservation Biology
This work describes how niche conservatism in climatic tolerances may limit geographic range expansion and how this one type of niche conservatism may be important in allopatric speciation and the spread of invasive, human-introduced species. Expand
Historical biogeography, ecology and species richness.
The chasm that has developed between ecology and historical biogeography is described, some of the important questions that have fallen into it and how it might be bridged, and a model that can help explain the latitudinal gradient of species richness is expanded. Expand
Niche conservatism as an emerging principle in ecology and conservation biology.
The mounting evidence for the importance of niche conservatism to major topics in ecology and conservation and other areas where it may be important but has generally been overlooked is described. Expand
Recurrent evolution of herbivory in small, cold-climate lizards: breaking the ecophysiological rules of reptilian herbivory.
It is shown that within a group of South American lizards (Liolaemidae, approximately 170 species), herbivory has evolved more frequently than in all other squamates combined and at a rate estimated to be >65 times faster. Expand
Missing data, incomplete taxa, and phylogenetic accuracy.

In this study, simulations are used to show that the reduced accuracy associated with including incomplete taxa is caused by these taxa bearing too few complete characters rather than too many missing data cells, and suggest a more effective strategy for dealing with incompleteTaxa. Expand
Hylid frog phylogeny and sampling strategies for speciose clades.
The results show that hemiphractine hylids are not closely related to other hyLids and should be recognized as a distinct family, and that the speciose genus Hyla is polyphyletic, but that its species can be arranged into three monophyletic genera. Expand
Evolutionary and Ecological Causes of the Latitudinal Diversity Gradient in Hylid Frogs: Treefrog Trees Unearth the Roots of High Tropical Diversity
Overall, this study illustrates how two general principles (niche conservatism and the time‐for‐speciation effect) may help explain the latitudinal diversity gradient as well as many other diversity patterns across taxa and regions. Expand
Global Patterns of Diversification and Species Richness in Amphibians

  • 1 August 2007
It is found that diversification rates in both frogs and salamanders increase significantly with decreasing latitude, which may shed light on both the evolutionary causes of the latitudinal diversity gradient and the dramatic but poorly explained disparities in the diversity of living amphibian clades.
