How many biogeographic regions are there?
ten biogeographic zones
Biogeographic classification of India is the division of India according to biogeographic characteristics. Biogeography is the study of the distribution of species (biology), organisms, and ecosystems in geographic space and through geological time. There are ten biogeographic zones in India.

What is biotic region?
: a geographic region characterized by the presence of one or more ecological associations that differ at least quantitatively from those of adjoining provinces and marked by a tendency to act as a center of ecological dispersion.
How many biogeographic realms are there?
8 Biogeographical Realms
The 8 Biogeographical Realms and 14 Biomes Used in the MA. Biogeographic realms are large spatial regions within which ecosystems share a broadly similar biological evolutionary history. Eight terrestrial biogeographic realms are typically recognized, corresponding roughly to continents.
Why is biogeographic region important?
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.
Why is Wallacea a hotspot?
It is believed that the main reason for the Wallacea’s high level of endemism is indebted to the formation of a speciation region (where new species are naturally bred) between the species on the two continents.
What country is Wallacea in?
Indonesia
The Wallacea region, that area of Indonesia marked by the Wallacea line to the West and the Lydekker line to the East and including Sulawesi, Timor and Lombok, is one of the most biologically interesting areas in the world.
What is the biogeography of the Palawan islands?
Palawan is species rich for its size, and represents the northeastern limit for many widespread Sunda Shelf genera absent from the rest of the Philippines.
How is the biogeography of Luzon island determined?
Previous biogeographic research has determined centres of endemism within the island. While the Pleistocene Aggregated Island Complex theory defines the island as one biogeographic region, recent phylogenetic studies suggest that the island may be composed by distinct centres of endemism that correlate with tectonic features.
What kind of geology does the Philippines have?
Though the country’s ancient geology, beginning at least in the Oligocene, had undoubtedly shaped Philippine biodiversity, biotic similarities of certain island groups only make sense in the light of the country’s Pleistocene history.
How big is the archipelago in the Philippines?
The Philippine archipelago is one of the world’s great reservoirs of biodiversity and endemism. The archipelago includes over 7000 islands, and a total land area of 300,780 km². The Philippines was never connected to mainland Asia via land bridges, so the flora and fauna of the islands had to cross ocean straits to reach the Philippines.
