Q.1 India is situated in the tri-junction of three realms. Name them. Ans Afro-tropical, Indo-Malayan and Palaeo-Arctic Q What is a Hotspot in Biodiversity?A biodiversity hotspot is a biogeographic region with a significant reservoir of biodiversity that is under threat from humans.

The concept of biodiversity hotspots was originated by Norman Myers in two articles in “The Environmentalist” (1988), & 1990 revised after thorough analysis by Myers and others in “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions”.

To qualify as a biodiversity hotspot on Myers 2000 edition of the hotspot-map, a region must meet two strict criteria: it must contain at least 0.5% or 1,500 species of vascular plants as endemics, and it has to have lost at least 70% of its primary vegetation. Around the world, 25 areas qualify under this definition, with nine other possible candidate (write the required portion only as per mark awarded)

Q Name the Biological Hotspots in India. India has two of the 25 hotspots identified throughout the globe. The two are Indo-Burma and the Western Ghats and Sri lanka.

Q. Expand IUCN.

Q Why Incredible India? India has 14 Biosphere reserves, 89 National Parks, 492 Wild life sanctuaries and 2 Biodiversity hotspots. (Statistics may be verified from latest updates)

Q What is a living fossil? Give examples to Indian context. An organism that is similar in appearance to its fossilized distant ancestors and usually has no extant close relatives. .e.g. such as the coelacanth or ginkgo Example from the text: Purple frog

Q Name two snakes belonging to the family Uropeltidae. The Uropeltidae is a family of primitive burrowing snakes endemic to southern India and Sri Lanka. The name is derived from the Greek words ura ("tail") and pelte ("shield"), indicating the presence of the large keratinous shield at the tip of the tail. Currently, eight genera are recognized comprising 47 species. These snakes are not venomous. The two snakes are Brachyophidium rhodogaster and Melaniphidium bilineatum (Two-lined black shieldtail)

Q What role has the Government played in protecting the Biodiversity of the Western Ghats? Identification of Key Biodiversity areas has already been initiated in the Western ghats. At present there are 88 Protected areas (13695 sq km) in the Western Ghats. The Government has established 2 Biosphere reserves, 13 National Parks and several wild life sanctuaries to protect specific endangered species. Many wild life sanctuaries have been upgraded into National parks.

Q Name the different type of forests in Western Ghats> Four types of Tropical and sub-tropical broad forests are found in the Western ghats. These are

a) North Western Ghats’ moist deciduous forest

b) North Western Ghats’ mountain rain forest

c) South Western Ghats’ moist deciduous forest

d) South Western Ghats’ mountain rain forest

Q How was the ecosystem of the Western Ghats affected by the arrival of the British? Large area of forest land was cleared for agriculture. The forest was fragmented and trees felled for tea, coffee and timber plantation. Rare and endemic and habitat specific species were adversely affected and they were lost faster than any other species.
