Community Ecology (Concepts (Community (It is a group of species that…

- - - - The relationship between area and species richness is called Species-area relationship
    - - It is obtained by plotting the number of species in each abundance class.
- - - - Feeding rate ( how quickly a predator find a new prey individual)
      - Handling time ( the amount of time needed to consume the prey)
    - - Zero growth isocline ( The line indicating population stability is Zero growth isocline)
    - - If the population falls to less than half its carrying capacity, the fixed effort harvest will remove fewer individuals from the population than are recruited into it, and the population will grow. This is one way in which a fixed effort harvest is less risky than a fixed quota harvest.
  - - - Foragers maximize fitness by maximizing energy intake rate
      - 2.Food items are encountered one at a time and in proportion to their abundance
      - 3.All food items in the environment can be ranked according to their profitability
        
        Profitability – the energy it contains divided by its handling time
    - - Exploitation competition ( Exploitation competition occurs indirectly through a common limiting resource which acts as an intermediate. For example, use of resources depletes the amount available to others, or they compete for space) .
      - Interference competition ( one organism prevents other organisms from using the resource) .
      - Apparent Competition ( Apparent competition is a type of indirect interaction that is defined as a negative effect of one species on the population growth rate or abundance of another species, mediated through the action of shared natural enemies. It can occur whether or not the two species compete directly for resources)
