Zoogeographic regions of Wallace, 1876. Zoogeography is the branch of the science of biogeography that is concerned with geographic distribution (present and past) of animal species.
Biogeographic realms correspond to the floristic kingdoms of botany or zoogeographic regions of zoology. From 1872, Alfred Russel Wallace developed a system of zoogeographic regions, extending the ornithologist Philip Sclater's system of six regions. [1] Biogeographic realms are characterized by the evolutionary history of the organisms they ...
This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
Terrestrial ecoregions of the world. This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial, freshwater, and marine ecoregions. The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms, containing 867 smaller ecoregions.
Formerly the region was mostly covered with forests and woodlands, but heavy human use has reduced much of the region to the sclerophyll shrublands known as chaparral, matorral, maquis, or garrigue. Conservation International has designated the Mediterranean basin as one of the world's biodiversity hotspots.
These regions are further subdivided into a variety of ecoregions. Many ecosystems and the animal and plant communities that depend on them extend across a number of continents and cover large portions of the Holarctic realm. This continuity is the result of those regions’ shared glacial history.
The world known to its population before contact with the "New World" (the Americas). Afro-Eurasia: 84,211,532: Largest contiguous landmass. Holarctic: 77,000,000: Biogeographic realm that encompasses the majority of habitats found throughout the northern continents of the world. Atlantic Ocean excluding adjacent seas: 76,762,000: Second ...
