title: Data from: Estimating synchronous demographic changes across populations using hABC and its application for a herpetological community from northeastern Brazil

description: Many studies propose that Quaternary climatic cycles contracted and /or
 expanded the ranges of species and biomes. Strong expansion-contraction
 dynamics of biomes presume concerted demographic changes of associated
 fauna. The analysis of temporal concordance of demographic changes can be
 used to test the influence of Quaternary climate on diversification
 processes. Hierarchical approximate Bayesian computation (hABC) is a
 powerful and flexible approach that models genetic data from multiple
 species, and can be used to estimate the temporal concordance of
 demographic processes. Using available single-locus data we can now
 perform large-scale analyses, both in terms of number of species and
 geographic scope. Here we first compared the power of four alternative
 hABC models for a collection of single-locus data. We found that the model
 incorporating an a priori hypothesis about the timing of simultaneous
 demographic change had the best performance. Secondly, we applied the hABC
 models to a dataset of 7 squamate and 4 amphibian species occurring in the
 Seasonally Dry Tropical Forests (Caatinga) in Northeastern Brazil, which,
 according to paleoclimatic evidence, experienced an increase in aridity
 during the Pleistocene. If this increase was important for the
 diversification of associated xeric-adapted species, simultaneous
 population expansions should be evident at the community level. We found a
 strong signal of synchronous population expansion in the Late Pleistocene,
 supporting the expansion of the Caatinga during this time. This expansion
 likely enhanced the formation of communities adapted to high aridity and
 seasonality and caused regional extirpation of taxa adapted to wet forest.
