Biodiversity and its conservation

The term biodiversity refers to the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it. Biodiversity includes not only species we consider rare, threatened, or endangered, but every living thing—even organisms we still know little about, such as microbes, fungi, and invertebrates. Biodiversity is important everywhere; species and habitats in your area as well as those in distant lands all play a role in maintaining healthy ecosystems.

  6. 6. Genetic diversity Includes the differences in DNA composition among individuals within a given species Adaptation to particular environmental conditions may weed out genetic variants that are not successful. But populations benefit from some genetic diversity, so as to avoid inbreeding or disease epidemics. 6Northern India Engineering College, New Delhi
  7. 7. Species diversity The number or variety of species in a particular region Species richness = number of species Evenness, or relative abundance = extent to which numbers of different species are equal 7Northern India Engineering College, New Delhi
  8. 8. Ecosystem diversity Includes diversity above the species level Biologists have viewed diversity above the species level in various ways. Some alternative ways to categorize it include: Community diversity Habitat diversity Landscape diversity 8Northern India Engineering College, New Delhi
  9. 9. Why is biodiversity important ? It maintains a healthy biosphere and provides both direct and indirect benefits to humans such as food, medicines, clothing and shelter! 9Northern India Engineering College, New Delhi
  10. 10. Benefits of biodiversity Conserving biodiversity preserves ecosystem services, and directly provides things of pragmatic value to us. • Food, fuel, and fiber • Shelter and building materials • Air and water purification • Waste decomposition • Climate stabilization and moderation • Nutrient cycling • Soil fertility • Pollination • Pest control • Genetic resources 10 Northern India Engineering College, New Delhi
