The concept of biogeography History Biogeography, the study of animal and plant distributions and known individually as zoogeography and phytogeographyrespectivelywas a subject that began to receive much attention in the 19th century.

This theory explained how the world was not created by one sole catastrophic event, but instead from numerous creation events and locations.

Additionally, this science considers the geographic constraints of landmass areas and isolation, as well as the available ecosystem energy supplies. This was inspired by his observations comparing the Old and New World, as he determined distinct variations of species from the two regions.

The vegetation in this hotspot originally extended oversquare kms. Climate India has a variety of climates, varying from Arid Desert in the West, Alpine climate in the Himalayan North to the humid tropical regions which support the island territories along with the rainforests in the southwest.

There are many water bodies in India in the form of rivers, canals, gulfs, backwaters, etc. The mountains rise to average altitudes between and m above sea level, intercepting monsoon winds from the southwest and creating a rain shadow in the region to their East.

Wallace conducted fieldwork researching the habits, breeding and migration tendencies, and feeding behavior of thousands of species. Vast reserves of metal ores and coal have been found in the Chota Nagpur plateau.

The Patkaior Purvanchal, are situated near India's eastern border with Burma. The vegetation is either dense evergreen forests or subtropical.

The broad Congo River in central Africa is a barrier between many congeneric species those that share the same genus of primates, such as the common chimpanzee Pan troglodytes found on the north side of the river and the pygmy chimpanzee P. It forms the higher part of the plains and is made of older alluvium soil which is less fertile.

Stream capture occurs when an upstream portion of one river drainage is diverted to the downstream portion of an adjacent basin. These were formed by the ongoing tectonic plates collision of the Indian and Eurasian plates.

This can happen as a result of tectonic uplift or subsidencenatural damming created by a landslideor headward or lateral erosion of the watershed between adjacent basins. For example, while classic biogeographers were able to speculate about the origins of species in the Hawaiian Islandsphylogeography allows them to test theories of relatedness between these populations and putative source populations in Asia and North America.

Physiographic Regions On the basis of its relief features, tectonic history and stratigraphy, India can be divided into several physical units. Many plant species are found even in the highest reaches of the Himalayan mountains.

Above submontane zone extend montane temperate forests upto m. Grey dotted lines stand for the state boundaries and will help you to get familiar with the Indian states and their neighbours.

It covers around 5. Buffon saw similarities between some regions which led him to believe that at one point continents were connected and then water separated them and caused differences in species.

Clarks recognized 11 botanical regions from India while Hooker divided into 9. Biogeographic region, area of animal and plant distribution having similar or shared characteristics throughout.

It is a matter of general experience that the plants and animals of the land and inland waters differ to a greater or lesser degree from one part of the world to another.

Jul 31,  · Dr. Manishika Jain explains the Biogeographical Regionalization - Aquatic Life Biogeographical classification: • Major Classifications • Terrestrial Plants • Terrestrial Animals •.

Systematic biogeography, the study of biotic area relationships, their distribution, and hierarchical classification; Evolutionary biogeography, the proposal of evolutionary mechanisms responsible for organismal distributions.

Possible mechanisms include widespread taxa disrupted by continental break-up or individual episodes of long-distance movement.
