What Are Biodiversity Hotspots And Why Is It Important ?
Indicator Species (Indicator Species) Species in which if there is even a slight change in climate, it will have a bad effect. Ex.(1) Lichens, fungi etc. are removed from their place with increasing temperature.(2) Coral bleaching occurs due to increase in temperature and pollution, hence coral is called the thermometer of the sea. South Pole 90 ° From the poles to the Mediterranean region the conditions are more favorable, thus increasing the biodiversity. Ex.Tropical monsoon v = y JesÃa indegusis . It is known that temperature is the main reason for biodiversity in mountain areas.(which decreases by 6.5 ° C for every 1 km of altitude, so very low temperatures do not create favorable conditions for organisms.
Fillofe vorbi lasku Bikople. India ranks 6th in the world and 4th in Asia in terms of biodiversity. Forests that are part of the Amazon rainforest, where biodiversity is in critical condition and rapidly disappearing, are not classified as biodiversity hotspots, as 70% of the biodiversity has not been lost. The highest human density in the hotspot area in the world is found in the Western Ghats of India (300 people).
Limbi Environmental Hotspot is called Biodiversity Hotspot (Bio Diversity Zone).An area where there is an abundance of species (high in number and diversity and especially those that occur in a single location). 2012 Biodiversity threatened by human activities. Terms of Biodiversity Hot Ten HAR (1) 0.5% of the world's biodiversity or 1500 species must be endemic to a region called a hotspot area. Mega (2) 70% of the area must be degraded or unprotected. (3) Where biodiversity is rapidly being lost. eg Selwa forests which are part of Amazon forests.
Government of India has declared 18 Biodiversity Hot Spots in India There are 35 such Biodiversity Hot Spots in the world, covering 2.3% of the world's area and 60% of the species found. 4 of the biodiversity hotspots are located in India.(a) Indo-Burma Region (b) Himalayan Region (c) Western Ghats and Sri Lanka (d) Sundalai Sundalanda Region, Nicobar Island.
Extinction of species in the Western Ghats - The Western Ghats region in India has suffered the highest loss of species due to human intervention. According to global human population statistics, the main tropical population density is found in Jenay 3 F 150G PR areas in the hotspot area. A is found in Western Ghats (300 individuals). Cause of extinction of species in the Himalayan region: Climate change and global warming in the Himalayan region is higher than the global rate.
Which has caused the extinction of many species in the Himalayas. Due to local geographical constraints, the movement of species towards Dhuwa is not possible. The Indo-Burma hotspot region is the best example of the highest degree of vegetation fragmentation. The recent tsunami in the Indian Ocean destroyed many parts of the Andaman Nicobar Forest (in Indo-Burma and Sundaland). The species in this hotspot area are being greatly affected by invasive species encroachment (excessive trampling), forest fires, drought and flood PRED.
Happening Marine Biodiversity Region Coastal region in India 7,516km is up to Marine Biodiversity Zone includes mangrove, estuaries, reefs etc. Bio-geographic Regions of India potsikeli Mir Bio-geographic region is a region where the characteristics and distribution of flora and fauna are unique compared to other regions of the world. There are 10 such biogeographical zones in India which differ in climate, topography, soil etc.
(1) Trans-Himalaya: Karakoram and Ladakh Mountains, Tibetan Plateau (2) Himalaya: North-West, Central and Eastern Himalayas. (3) Marasthal Desert. Thar Desert, Desert of Kutch. (4) Western Ghats: Malabar Plains, Western Ghats. (5) Deccan Highlands: Central Highlands Chhota Nagpur Highlands, Eastern Highlands, 0 Biogeographic Region of India - Trans-Himalaya Himalayas A desert region 2 Semi-arid or Western Ghats Bipolar region - Gangetic plains - Sea coastal regions 26. North-Eastern Regions 1. Island.
Semi-arid Zone Plains: Division, Ekangi Punjab's Syzophyta Ex. : Bacteria Gangetic plain area : High and low Gangetic plain area Fauna Diversity in India All organisms found in the world are divided into two categories : Forest classification. There are different methods of plant classification. Of which according to Eichler's system of classification: Vegetation Sub-system: Apushpi Maidan, Gujarat's Dwiangi Ex. : Riccia moss lill Ex. Oscillatoria Spirogyra Sargesum Batrachospermum triangi Ex. Nephrolepis Coastal Region: East and West Coastal Area, Lakshadweep North-Eastern Region: Brahmaputra Valley, North-East Peak Region Archipelago: Andaman-Nicobar Archipelago Fungi e.g. : Yeast Chukar Mushroom (1) Vegetative section: Involucral spore ex. : Pinus, Cycus lichen eg. : Parmelia usnia (2) Animals Class : Bivalve Ex. : Sunflower seeded unilobed e.g. : Maize.
Flowering plants (Phanerogamae) Plants with seeds or flowers.1 Gymnosperms Plants of this division have open or naked seeds. There are small plants to very large plants. It is called Coast Redwood of California. Zamia pygmia is the smallest angiosperm. Draganayana is done by wind. Ex :Coniferous forest species like Cycus, Orocaria, (Christmas tree), Thuja (ornamental plants in gardens) 2. Angiosperm. Plants in this division have seeds inside the fruit i.e., seed coat. Root, leaf, fruit, flower etc. are fully developed. The reproductive organ is the flower (flower). Pollination is done by wind, insects and birds.
Globoza is the smallest species (2-5 mm) and Nilgiri (Eucalyptus) is the largest. (height 90-100 m). Currently, this group is the group that includes the maximum species of the earth. Monocotyledon + seed has a single cotyledon. Ex. : Maize, Wheat, Sorghum, Rice, Barley, Garlic, Onion, Betel nut, Date etc. Dicotyledons seeds have two cotyledons.Ex. : Groundnut, pulses, cotton, okra etc. Inflorescence 4 Plants in this class are flowerless two seedless. 1.Thalophyta The largest division of plants. Plants of this division do not have organs like roots, stems, leaves. That is, it is dry. This includes various algae, fungi, bacteria and lichens.
Hotspot is called Biodiversity Hotspot (Bio Diversity Zone). An area where there is an abundance of species (high in number and diversity and especially those that occur in a single location. Where biodiversity is threatened by human activities, the terms for a Biodiversity Hotspot
(1) 0.5% of the world's biodiversity or 1500 species must be endemic to a region called a hotspot area.
(2) 70% of the area must be degraded or unprotected.
(3) Where biodiversity is rapidly being lost. Eg Selwa forests which are part of Amazon forests.Government of India has declared 18 biodiversity hotspots in India.There are 35 such biodiversity hotspots in the world, covering 2.3% of the world's area and 60% of the species found. out of 35 of the world's.
(4)biodiversity hotspots are located in India.(a) Indo-Burma Region (b) Himalayan Region (c) Western Ghats and Sri Lanka (d) Sunda Sundalanda Region, Nicobar Island.
