India has a total of …… biogeographical regions?

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. Why should this be? Why should the same species not exist wherever suitable environmental conditions for them prevail? Geographic regions around the world that have similar environmental conditions are capable of harbouring the same type of biota. This situation effectively separates the How the unique distributions of animals and plants in various biomes came to be is not explicable purely through present climatic factors and latitudinal zonation. Geologic events such as 1 and 2). General features The concept of History Biogeography, the study of animal and Philip L. Sclater, who based his division of the terrestrial world on the distributions of birds. In the 1870s the biologist On the Origin of Species Darwin included two key chapters (12 and 13) on geographic distribution in which he referred to both Hooker and Wallace. At high altitudes in the tropics Hooker had found plants that were normally restricted to temperate zones, and Darwin interpreted these observations as evidence of past Geographic factors have played a significant role at every level of taxonomic division. Populations that become isolated by means of a geographic barrier will tend to diverge from their species. Although thes...

It comprises three biogeographic provinces – Ladakh mountains, Tibetan plateau and Himalayan Sikkim. It accounts for ~5.6% of the country’s landmass. This region mostly lies between 4,500 to 6,000 metres (14,800 to 19,700 ft) and is very cold and arid. The only vegetation is a sparse alpine steppe.

Solution: Number of Biogeographical regions in India - 10 The study of the distribution of species (biology), organisms, and ecosystems in geographic space and through geological time is called Biogeography. Biogeographical regions is an area of animal and plant distribution which has similar or shared characteristics throughout. India has a total of 10 such regions as follows - Trans-Himalayan Region, Himalayan Zone, Indian Desert Zone, Semi Arid Region, Western Ghats, Deccan Plateau, Gangetic Plain, North East Region, Coastal Region, and Islands.

An area of animal and plant distribution which has similar or shared characteristics throughout is known as a Biogeographical region. In India, 10 such regions are identified. The areas areTrans-Himalayan Region, Himalayan Zone, Indian Desert Zone, Semi-Arid Region, Western Ghats, Deccan Plateau, Gangetic Plain, North East Region, Coastal Region and Andaman and Nicobar islands. Great biodiversity is observed in such areas.

With 23.39% of its geographical area under forest and tree cover, India is rich in biodiversity. A 2020 faunal survey of India by the There is insufficient information about the invertebrate fauna of India, with significant work having been done only in a few groups of insects, notably the There are about 2,546 species of fishes (about 11% of the world species) found in Indian waters. About 197 species of amphibians (4.4% of the world total) and more than 408 reptile species (6% of the world total) are found in India. Among these groups the highest levels of endemism are found in the amphibians. There are about 1361 species of birds recorded from India, with some variations, depending on taxonomic treatments, accounting for about 12% of the world species. There are about 410 species of mammals known from Ind...

The term biogeographic realm refers to an area of land that contains relatively similar living organisms. In most cases, the organisms living within these biogeographic realms have been isolated from the rest of the organisms around the world and have, therefore, experienced distinct evolutionary processes. In other words, each realm corresponds to a specific evolutionary history. Biogeographic realms are further divided into ecoregions, which are, in turn, divided into biomes. This article takes a closer look at each of the 8 biogeographic realms: Antarctic, Oceania, Indo-Malaya, Australasia, Neotropic, Afrotropic, Nearctic, and Palearctic. Antarctic Biogeographic Realm The Antarctic biogeographic realm covers a total area of 0.12 million square miles, making it the smallest of all the realms. The Antarctic biogeographic region is located in the Southern Ocean and is comprised of the area surrounding the South Pole, including: Antarctica, the islands above the Antarctic tectonic plate, the ice in the waters, and the ocean itself. All of these different components make up 20% of the Southern Hemisphere. Because of the freezing temperatures here, just under 1% of the Antarctic is actually exposed land. This realm is home to plant species such as: lichens, mosses, Antarctic hair grass, and microfungis. Additionally, some animals species may be found here, depending on the time of year. These animal species include: penguins, whales, squid, albatross, seals, and Antarctic pet...

ADVERTISEMENTS: India has only 2.4% of the world’s land area, but contributes about 8.1% to global species diversity. This makes India one of the 12 mega biodiversity countries in the world. The country is divided into 10 biogeographic regions. The diverse ecological habitats such as forests, grasslands, wetlands, coastal and marine ecosystems and desert ecosystems have helped to harbour and sustain immense biodiversity in the country. The Indian subcontinent is rich in biodiversity with a good percentage of endemic flora and. fauna. This richness in biodiversity is due to variety of climate, topography and varied ecological habitats. These vary from the humid tropical Western Ghats to the hot deserts of Rajasthan, from the cold desert of Ladakh and snowcapped mountains of Himalayas to the warm coasts of peninsular India. ADVERTISEMENTS: The country is one of the 12 primary centres of origin of cultivated plants and domesticated animals. It is considered to be the homeland of 167 important cultivated plant species of cereals, millets, fruits, condiments, vegetables, pulses, fibre crops and oilseeds, and 114 breeds of domesticated animals. The cultivated crops include rice, sugarcane, jute, mango, and several medicinal and aromatic plants (Table 2). The trees of India are listed in Table 3. The numbers of the different kinds of animals are listed in Table 4. There are over 45,000 species of plants and 75,000 species of animals identified. There are more than 100,000 plant s...

Early biogeographers identified the existence of multiple zoogeographical regions, characterized by faunas with homogeneous composition that are separated by biogeographical boundaries. Yet, no study has deciphered the factors shaping the distributions of terrestrial biogeographical boundaries at the global scale. Here, using spatial regression analyses, we show that tectonic movements, sharp changes in climatic conditions and orographic barriers determine extant biogeographical boundaries. These factors lead to abrupt zoogeographical transitions when they act in concert, but their prominence varies across the globe. Clear differences exist among boundaries representing profound or shallow dissimilarities between faunas. Boundaries separating zoogeographical regions with limited divergence occur in areas with abrupt climatic transitions. In contrast, plate tectonics determine the separation between deeply divergent biogeographical realms, particularly in the Old World. Our study reveals the multiple drivers that have shaped the biogeographical regions of the world. We believe...
