GIS layers of biodiversity data
GIS data used in creating this site’s maps are available in several formats.
For the Brazil maps, GIS data are available on Dryad at http://dx.doi.org/10.5061/dryad.6rv61
For marine biodiversity, GIS data are available on Dryad at http://dx.doi.org/10.5061/dryad.3mn1t
A description of the methods used to prepare the biodiversity maps can be found here.
As a complement to the biodiversity data, the Natural Earth site is a good source for GIS layers on political and biophysical features.
