Study Notes
Biodiversity
- Biodiversity refers to the variety of life on Earth, encompassing all living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems.
- The term "biodiversity" was coined by W.G. Rosen in 1986.
- Edward O. Wilson is considered the "father" of biodiversity research.
- Biodiversity encompasses three levels: genetic diversity, species diversity, and ecosystem diversity.
Genetic Diversity
- Genetic diversity refers to variations within a species.
- Unique genetic traits allow populations to adapt to changing environmental conditions.
- Examples: different rice varieties, fungi, and wheat.
Species Diversity
- Species diversity refers to the range of species within a region or community.
- Species richness is greatly influenced by climate conditions, with diverse climates supporting larger species counts.
Ecosystem Diversity
- Ecosystem diversity refers to the variety of habitats, communities, and ecological processes within a region.
- Examples include temperate forests, deserts, lakes, and kelp forests.
- There are three types of ecosystem diversity**: alpha diversity, beta diversity, and gamma diversity.
Significance of Biodiversity
- Biodiversity is essential for a healthy ecosystem. All living organisms are interconnected through food chains and food webs, exchanging energy.
- The destruction of one type of wildlife can upset the ecological balance.
- Biodiversity provides a source of genetic material for breeding programs in agriculture.
- Biodiversity has significant economic, aesthetic, and religious importance.
Importance of Plants
- Plants are crucial for aesthetic and commercial value.
- Many plants are worshipped in India, such as the peepal, banyan tree, and tulsi.
- Plants provide useful products like timber, paper, coffee, and tea.
Importance of Wild Animals
- Wild animals provide a source of food and research materials for drug development.
- Examples include Papaver Somifera (morphine drugs), Quinine (malaria treatment), and Taxus brevifolia (anticancer drugs).
Biodiversity Loss
- Biodiversity loss is a major environmental issue caused by habitat destruction, overexploitation, invasive species, pollution, climate change, and population growth.
- These factors threaten the balance of ecosystems and the survival of many species.
Main Reasons for Environmental Issues
- Anthropogenic activity: Human activities and their direct impact on the environment.
- Natural interference: Natural events and processes that influence the environment.
- Nature of factors: These include pollution, drought, cyclones, low population densities, infectious diseases, and the presence of invasive species.
Man-made Factors
- Destruction of habitats: This leads to habitat loss and fragmentation, disrupting ecosystems and species populations.
- Over-exploitation of species: Overfishing, poaching, and unsustainable harvesting threaten species survival.
- Exotic species: Invasive species can disrupt native ecosystems and compete with native species for resources.
- Other causes: Population change, climate change, pesticides, and insecticides contribute to biodiversity loss.
