Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude , elevation , isolation and habitat area . [ 1 ]
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.
A biogeographic realm is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions.
Bioregional mapping is a participatory approach to cartography that focuses on mapping the natural, ecological, and cultural features of a bioregion—an area defined by its natural boundaries, such as watersheds, ecosystems, and cultures that arise form a place, rather than human borders. [1]

Panbiogeography, originally proposed by the French-Italian scholar Léon Croizat (1894–1982) in 1958, [1] [2] is a cartographical approach to biogeography that plots distributions of a particular taxon or group of taxa on maps, and connects the disjunct distribution areas or collection localities together with lines called tracks , regarding vicariance as the primary mechanism for the ...
Zoogeography is the branch of the science of biogeography that is concerned with geographic distribution (present and past) of animal species. [ 1 ] As a multifaceted field of study, zoogeography incorporates methods of molecular biology, genetics, morphology, phylogenetics , and Geographic Information Systems (GIS) to delineate evolutionary ...
In biogeography, realms most often refer to the broadest classification of Earth's land surface, based on distributional patterns of terrestrial organisms in 8 major divisions. [19] Within the IUCN Ecosystem Typology, Level 1 "realms" refer to 5 major divisions of the biosphere -- Terrestrial, Subterranean, Freshwater, Marine, Atmospheric.
