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.
