Species Interactions

INTERACTION SPECIES 1 SPECIES 2 COMMENTS

NEUTRALISM 0 0 NEITHER POP AFFECTS THE OTHER

COMPETITION - - INHIBITION OF EACH SPECIES BY THE OTHER

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

PARASITISM

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

COMMENSALISM + 0 SPECIES 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.

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

  • 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 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 Predatorshttp://greateryellowstonescience.org/files/pdf/Laketrout_Almanac_YELL.pdf

Kills per predator

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

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