AMENSALISM-0SPECIES 1 IS INHIBITED, SPECIES 2 IS NOT AFFECTED

PARASITISM

PREDATION+-SPECIES 1 BENEFITS AT THE EXPENSE OF SPECIES 2

COMMENSALISM+0SPECIES 1, THE COMMENSAL, BENEFITS WHILE SPECIES 2, THE HOST, IS NOT AFFECTED

MUTUALISM++INTERACTION IS FAVORABLE TO BOTH SPECIES


PREDATION

  • Predation - consumption of live prey by an organism, predators attach several prey individuals over their lives.


PREDATION

  • Predation - consumption of live prey by an organism, predators attach several prey individuals over their lives.

  • Grazers - attack many prey individuals but only consume parts of the prey, and attacks are rarely lethal.

  • Parasites - consume only parts of prey, rarely lethal, attack only one or a few prey over parasite’s lifetime.


Predator Effects on Prey

Predators have minor effect on prey populations if:

  • Predators take prey individuals with the lowest fitness. (e.g. muskrat)


Predators have minor effect on prey populations if:

  • Predators take prey individuals with the lowest fitness. (e.g. muskrat)

  • Prey may compensate for predation by increased survival and reproduction of survivors. (e.g. coyote)


Predators have minor effect on prey populations if:

  • Predators take prey individuals with the lowest fitness. (e.g. muskrat)

  • Prey may compensate for predation by increased survival and reproduction of survivors. (e.g. coyote)

  • The effects of one species of predator are replaceable by another predator species. (e.g. wolves, bear, moose)


Prey Effects on Predators

Kills per predator

FUNCTIONAL PREDATOR RESPONSE - Changes in predator consumption rates associated with changes in prey density.


Prey Effects on Predators

NUMERIC PREDATOR RESPONSE - Changes in predator density in response to prey density.
