Ch. 26 Community Ecology, demonstrating succession, https…

- - - - common observation is matters
    - - relationship b/t area & species richness
    - - number of species
        
        in each abundance class
- - - - feeding rate & handling time
      - prey-dependent
    - - line indicating population stability
    - - predator overexploit prey
      - both species lost
    - - harvest just enough to keep pop density
      - species would be stable
    - - can be harvested w amount of effort
    - - harvest only particular amount
  - - - examine why herbivores eat certain plants
    - - predators pick high-yield prey
      - if prey become scare, broaden diet
      - some prey will always be eaten
      - less profitable prey will be ignored if more available
  - - - organisms consume shared resource
    - - organisms restrict access to other resources
    - - when population can increase
      - even with competitor
- - - - trace prey of top carnivores
      - trace food sources of prey
    - - how energy flows through community
    - - direct line of consumption
    - - dramatically affects community structure
