Study Notes
What is Biodiversity
- Biodiversity combines "bio" (life) and "diversity," representing the variety of living organisms across ecosystems.
- The Convention on Biological Diversity was established in 1992 during the Rio Earth Summit.
- India ranks 10th globally in plant richness, 11th in endemic higher vertebrates, and 6th in agricultural crop diversity.
Levels of Biodiversity
- Genetic Diversity: Variations within the genes of the same species, leading to different varieties (e.g., rice, mangoes).
- Species Diversity: Variation among species within a specific area (e.g., horses distinct from donkeys).
- Ecosystem Diversity: Variety of habitats and life forms within them, encompassing different ecosystems within geographical boundaries.
Values of Biodiversity
- Productive Value: Various products are sourced from organisms, including silk from silkworms and wool from sheep.
Hot Spots of Biodiversity
- Major biodiversity hotspots in India include:
- Western Ghats
- Eastern Himalayas
- Indo-Burma region
- Sundaland (Nicobar Islands)
Endangered Species
- Species close to extinction are classified as endangered (e.g., red panda, Gir lion, Gharial, Great Indian bustard).
Vulnerable Species
- Vulnerable species are likely to become endangered without improved circumstances (e.g., Sarus crane, Nilgiri Langur, Barasingha).
Rare Species
- Rare species are uncommon or infrequently encountered and not classified as endangered but are "at risk."
Red Data Book
- A document by IUCN that catalogs rare and endangered species of flora and fauna, including local species.
Endangered Black Buck
- Also known as kala hiran, previously widespread in India but now limited to parts of Punjab, Gujarat, and Rajasthan due to poaching and habitat loss.
Endemic Species
- Species native to a particular region, with limited distribution (e.g., True Cardamom, One-horned rhino, Royal Bengal tiger).
EDGE Species
- Evolutionarily Distinct and Globally Endangered species have unique evolutionary histories and few close relatives (e.g., Asian elephants, red pandas).
Ex-situ Conservation
- Botanical Gardens: Preserve rare and endangered plant species and promote research and sustainable development.
- Tissue Culture Technique: Asexual propagation method using plant cells in sterile conditions to conserve genetic material.
- DNA Technology: Uses DNA conservation methods for biodiversity preservation.
Advantages and Disadvantages of Ex-situ Conservation
-
Advantages:
- Complete protection from predation and poaching.
- Extended survival rates and possible hybrid breeding.
- Improved offspring quality through genetic techniques.
-
Disadvantages:
- Abnormal behavior in animals can complicate reproduction.
Man-Wildlife Conflict
- Conflicts arise when wildlife threatens human safety and damages property, complicating conservation efforts.
Phyto-geographical Regions of India
- India categorized into regions based on flora:
- Western Himalayas
- Eastern Himalayas
- Western Deserts
- Gangetic Plains
- Central India
- Western Coast
- Deccan Plateau
- North-East India
- Andaman and Nicobar Islands
Zoo-geographical Regions of India
- India divided into regions based on fauna:
- Himalayan Region
- Malabar Region
- Nilgiri Region
- Northern Plains
- Desert Lands
- Deccan Plateau Region
India: A Mega-diversity Nation
- Recognized as one of 18 mega-diverse countries by Conservation International in 1998.
- Key fields of diversity in India include geographical, climatic, habitat, cultural, and biodiversity.
