TL;DR: 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.

TL;DR: 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.

TL;DR: 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.

TL;DR: 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.

TL;DR: This article investigated the potential distribution of Seasonally Dry Tropical Forests (SDTFs) during Quaternary climatic fluctuations; to reassess the formerly proposed Pleistocenic arc hypothesis (PAH); and to identify historically stable and unstable areas of SDTF distributions in the light of palaeodistribution modelling.
