Biogeographical Districts of the Caatinga Dominion: A Proposal Based on Geomorphology and Endemism - Supplementary data

These are the supplementary data to the article "Biogeographical Districts of the Caatinga Dominion: A Proposal Based on Geomorphology and Endemism", published in The Botanical Review. Our study proposes a subdivision of the Caatinga Dominion into biogeographical Provinces, Subprovinces and Districts, and propose an inedited geomorphological and biogeographical map to the whole Caatinga.We provide here the geomorphological map and the shapefile used to produce this map to allow readers to create their own maps based on our proposal. We also provide our biogeographical map in high resolution (in JPEG and PDF formats, with and without the Brejos Nordestinos de Altitude enclaves and with and without the borders of the Brazilian states) for download. The shapefiles used to create our biogeographical map is also available here, with the limits of the proposed biogeographical districts.The mapping of the enclaves of humid forests within Caatinga (Brejos Nordestinos de Altitude district) is a research still in progress by Taynara Rabelo-Costa. She kindly provided a preliminary version of her mapping to allow readers of this article to have an overview of the distribution of these enclaves, but a final version of her map is still being produced and this version should be considered non-final when our study is released. We also provide here a spreadsheet with 329 endemic Caatinga species recording in which district each species is known. Some endemic species are widespread inside Caatinga, while others are restricted to one or few districts.We stimulate biogeographers and those mapping biodiversity in Caatinga to create their own maps, for their own study group, based on our proposal.
