Study Notes
Biodiversity
Ecosystem Diversity
- Refers to the variety of ecosystems within a particular area.
- Includes different habitats, communities, and ecological processes.
- Important for maintaining balance and resilience in the environment.
- Examples: forests, wetlands, grasslands, coral reefs.
Species Diversity
- Involves the number of different species and their relative abundance in an ecosystem.
- High species diversity typically indicates a healthy ecosystem.
- Measured using metrics like species richness (number of species) and species evenness (distribution of individuals among species).
- Crucial for ecosystem services such as pollination, nutrient cycling, and habitat provision.
Genetic Diversity
- Refers to the variety of genetic information within a species or population.
- Essential for adaptability and survival in changing environments.
- High genetic diversity can enhance resilience to diseases and environmental changes.
- Conservation of genetic diversity is important for agriculture and wildlife management.
Threats To Biodiversity
- Habitat destruction (e.g., deforestation, urbanization).
- Climate change impacting species distribution and ecosystem functions.
- Pollution (e.g., water, air, soil) affecting organism health and habitat quality.
- Invasive species outcompeting native species for resources.
- Overexploitation of resources (e.g., overfishing, poaching).
Conservation Strategies
- Protected areas: Establishing national parks, reserves, and marine protected areas.
- Restoration ecology: Rehabilitating degraded ecosystems to restore biodiversity.
- Sustainable practices: Implementing agriculture, forestry, and fishing practices that minimize environmental impact.
- Legislation and policy: Enforcing laws to protect endangered species and habitats.
- Community involvement: Engaging local communities in conservation efforts and promoting awareness.
Ecosystem Diversity
- Variety of ecosystems includes different habitats, communities, and ecological processes.
- Vital for maintaining environmental balance and resilience.
- Examples of ecosystems: forests, wetlands, grasslands, coral reefs.
Species Diversity
- Measures the number of different species and their relative abundance within an ecosystem.
- High species diversity indicates a healthy ecosystem and its ability to function effectively.
- Metrics include species richness (total number of species) and species evenness (distribution of individuals among species).
- Essential for providing ecosystem services like pollination, nutrient cycling, and habitat provision.
Genetic Diversity
- Variety of genetic information within a species or population influences adaptability to environmental changes.
- High genetic diversity enhances resilience against diseases and environmental shifts.
- Conservation of genetic diversity is crucial for agriculture and wildlife management, ensuring sustainable practices.
Threats to Biodiversity
- Habitat destruction through activities such as deforestation and urbanization reduces ecosystem viability.
- Climate change alters species distribution and disrupts ecosystem functions.
- Pollution (water, air, soil) negatively affects organism health and habitat quality.
- Invasive species can outcompete native species, leading to declines in biodiversity.
- Overexploitation of resources, including overfishing and poaching, threatens species survival.
Conservation Strategies
- Creation of protected areas like national parks, reserves, and marine protected zones to safeguard biodiversity.
- Restoration ecology focuses on rehabilitating degraded ecosystems to revitalize biodiversity.
- Implementation of sustainable practices in agriculture, forestry, and fishing helps protect the environment.
- Enforcement of legislation and policies to protect endangered species and their habitats is essential.
- Community involvement increases local engagement in conservation efforts and raises awareness about biodiversity issues.
