The document discusses a 2008 paper that used climate modeling to examine how past climates affected the distribution of Brazil's Atlantic forest and identify areas that acted as refuges for forests. The authors then analyzed genetic data from five taxa to look for correlations between areas of high genetic diversity and the predicted refuge forests. They found matches for three of the five taxa, with the other two showing higher diversity in regions not predicted by the models. The paper provides evidence that past refuge forests predicted areas of high endemism and genetic diversity in some species.
