What are the biogeographical regions?
Biogeographic regions are geographical areas that are defined based on the species found in them, which provides invaluable information to ecologists and natural resources managers for understanding large scale processes that affect species and ecosystems.

Based on the original proposal of Philip Sclater and Alfred Wallace, the Earth’s land surface is divided into six biogeographic regions: Nearctic region, Palaearctic region, Neotropical region, Ethiopian region, Oriental region, and Australian region.
Which biogeographic region is North America?
Nearctic
It has been divided in two regions: the Nearctic in the New World and the Palearctic region in the Old World (Morrone, 2002). The Nearctic region occupies almost all North America, and has been recognized since Sclater and Wallace in the 19th Century.

What is Wallace’s The geographic distribution of animals?
Wallace’s 1876 book, The Geographic Distribution of Animals, has plates depicting the animal life of the biogeographic regions he identified. These are mammals typically found in the forests of Borneo.
What is the contribution of Alfred Wallace in geography?
Alfred Russel Wallace (1823–1913) played a key role in defining and recognising biogeographic regions. He improved the existing maps of biogeographic regions and provided basic rules to identify them.
What is Wallace’s theory of region organization?
Wallace realised that the organisation of biogeographic regions has to be hierarchical and that large regions can be divided in sub-regions. Accordingly, he identified four different sub-regions for each of the six main regions (see the map above).
What is a biogeographic region?
Wallace defined the biogeographic regions as “Those primary divisions of the earth’s surface of approximately continental extent, which are characterised by distinct assemblages of animal types”. He also provided characteristics that biogeographic regions should have – giving us a clear way to identify them:
