    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.
