Lecture 4: Biodiversity - Coggle Diagram

- - - - reduce competition (niche partitioning)
        
        Niche Specialization (increase biodiversity)
        
        Enhance Resilience (Multiple species performing similar functions act as "backups" if one species declines (e.g., disease resistance).)
  - - - can adapt new envir due to variation
        
        survival advantage
        
        disease is less likely to affect poplation
- - - - n = individuals of a species; N = total individuals.
  - - - Diversity within a specific habitat.
    - - Variation in species between habitats.
    - - Total diversity across multiple habitats.
- - - - Panama: >500 bird species vs. Arctic: 50–100 species.
      - 50% of Earth’s species in tropical rainforests; 1/3 of marine species in coral reefs.
- - - - Increasing climate change
      - Decreasing CO2 storage sequestered from atmosphere
      - Increasing biodiversity loss
      - :green_cross: conserve tree/ plant species diversity
      - Decreasing climate change
      - Increasing CO2 storage sequestered from atmosphere
      - Decreasing biodiversity loss
      - :check:Conserve tree/ plant species diversity
  - - - Biodiversity in farms and wild areas limits zoonotic disease spillovers (e.g., Lyme disease, COVID-19) by maintaining natural barriers between humans and pathogens.
      - Genetic diversity (pest-resistant rice) & functional diversity (pollinators) can ensure resilience aganist pest, diesease + reduce reliance on chemical inputs
