CMEC Zoogeographic Realms and Regions
This study updated Alfred Russel Wallace's 1876 map on the zoogeographic regions of the world, which has been the backbone for our understanding of global biodiversity for over a century. The research is published in Science. Free access is available to the abstract, print version and online-version.
Our work is based on the distributions and phylogenetic relationships of all terrestrial mammals, birds and amphibians. The details and references for these data sources are provided in the materials and methods section of our manuscript. The bird distributional data were compiled here at the Center of Macroecology, Evolution and Climate (CMEC) and further details for these data can be obtained by following the link at the bottom of the page. The phylogenetic and distributional data for all three taxonomic groups were combined to produce our updated version of Wallace’s map.
Our global map divides the world into 11 zoogeographic realms, which are further subdivided into 20 regions. Google Earth and GIS maps of zoogeographic realms and regions can also be found here.

Information on the distribution and evolutionary relationships of over 20,000 species of amphibians, birds and mammals and used to identify the world's 11 zoogeographic realms
The colours of the realms reflect the phylogenetic distinctiveness of the animal assemblages found within them. That is, realms with similar colours contain similar families and genera of animals and those with different colours have few groups of animals in common.
The realms are further divided into 20 regions, shown with the dotted white lines.
