Community Ecology (Metapopulations in patchy environments (4 assumptions…

- - - - prey-dependent
    - - loss of both species
    - - fixed quota
        
        depends on legality
      - maximum sustained yield
        
        species stability through harvest
      - fixed effort
        
        harvest depends on population health
  - - - optimal diet model four predictions
        
        energy per unit of handling
        
        broaden diet for lower energy prey
        
        things to always/never eat
        
        less profitable prey ignored
  - - - consumption of shared resourses makes them less available
    - - access restriction
- - - - S=cA^z
- - - - dramatically effects community structure
- - - - organisms are established on new substrates
