- - - - net rate of change
        
        dN/dt=rN-aNP
      - equation for the net rate of change of predator numbers is dP/dt=faNP-qP
  - - - resource competition occurs when the organisms actually consume a shared resource, thus making it less available to other organisms
    - - one organism restricts another organisms access to resources even though the first might not be using it
  - - - probability that a particular prey individual will be encountered
      - the decision by the predator to attack an individual once it has been encountered
      - the probability that an attacked prey will be successfully eaten
- - - - relationship between area and species richness
