Scientists have developed the first map of the world's unique and most endangered mammals and amphibians.
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 been developed by the Zoological Society of London (ZSL) to highlight species that are both distinctive and under severe threat.
The map highlights the regions of the world where the highest concentrations of these species occur and which should be priorities for conservation efforts.
"If you look at mammals, if you look at just evolutionary history, the species that are more different from all others, the deep rooted ones tend to be in South America," Prof Jonathan Baillie, Director of Conservation at ZSL told BBC News.
"But if you incorporate threat, then the focus changes to South East Asia and the reason is that land conversion has been so rapid there due to things like palm oil that a lot of these species are highly threatened - they come up to the top when you add threat as a variable." More....
