Community Ecology (predator-prey interactions (competition between species…

- - - - 1st predator should prefer whichever prey yields the most energy per unit of handling time
      - 2nd the high yield prey become more sufficiently scarce, & the predator would broaden its diet to include prey of lower energy id they abundant to eat
      - 3rd some prey items will always be eaten if they re encountered, other will never be eaten if easy to obtain
      - 4th the probability that a particular plant will be eaten depend partially on the abundance of other plants that are eat to handle & have higher value
- - - - 1. a region of environment is composed of many discrete patches in which the species can live
      - 2. some patches are occupied by the species whereas other suitable patches are not
      - 3. empty patches will become colonized by migration from occupied patches
      - 4. populations within individual patches have probability of going extinct within that patch
