Unit 2389: Ecosystem Resilience

1. Introduction to Ecosystem Resilience

• Definition and scope of ecosystem resilience
• Importance of resilience in ecosystem sustainability
• Key components: resistance, recovery, and adaptability

2. Factors Influencing Ecosystem Resilience

• Biotic factors:
  • Biodiversity and species interactions
  • Keystone species and functional diversity
• Abiotic factors:
  • Climate variables
  • Soil, water, and nutrient availability
• Anthropogenic influences:
  • Habitat destruction
  • Pollution
  • Land-use change

3. Case Studies of Resilient Ecosystems

• Coral reefs:
  • Adaptation to bleaching events
  • Role of symbiotic relationships
• Rainforests:
  • Recovery after logging or fire disturbances
  • Biodiversity as resilience driver
• Wetlands:
  • Flood regulation and nutrient cycling
  • Response to pollution and invasive species

4. Ecological Feedback Mechanisms

• Overview of feedback loops in ecosystems
• Positive feedback loops and potential risks
• Negative feedback loops maintaining stability
• Trophic cascades and their influence on resilience
• Resilience thresholds and tipping points

5. Human Impact on Ecosystem Resilience

• Pollution effects on ecosystem function
• Deforestation and habitat fragmentation
• Overfishing and marine ecosystem degradation
• Urbanization and its ecological footprint
• Case examples of ecosystem collapse linked to human activity

6. Strategies for Enhancing Ecosystem Resilience
