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.
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 . [ 1 ]
It includes both the Nearctic zoogeographical region (which covers most of North America), and Alfred Wallace's Palearctic zoogeographical region (which covers North Africa, and all of Eurasia except for Southeast Asia, the Indian subcontinent, the southern Arabian Peninsula).

The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
Heating of solids, sunlight and shade in different altitudinal zones (Northern hemisphere) [5] A variety of environmental factors determines the boundaries of altitudinal zones found on mountains, ranging from direct effects of temperature and precipitation to indirect characteristics of the mountain itself, as well as biological interactions of the species.
One widely accepted scheme draws the dividing line along the crest of the Greater Caucasus range, putting the portion of the region north of the line in Europe and the portion south of it in Asia. Another puts the western portion of the Caucasus region in Europe and the eastern part (the bulk of Azerbaijan and small portions of Armenia, Georgia ...
