The map highlights the fact that only a fraction of the areas identified as critical for the conservation of these species are protected.
Among the species highlighted by the map are the Mexican salamander, the Sunda pangolin and the black and white ruffed Lemur.
The research is published in the journal Plos One.
The Evolutionarily Distinct and Globally Endangered (EDGE) project has...
