individuals interact directly with one another by physical force or intimidation
Back
Exploitation competition
Front
individual is affected by amount of resources that remains after it has been exploited by the other neighboring individuals; occurs ONLY when resources are limited
Back
niche partitioning
Front
When two species naturally divide different resources based on competitive advantages; ex: one squirrel eats from the ground and one squirrel eats from the top of trees
Back
role of disturbance for maintaining species richness
Front
Revenge of wimps: species that cannot out compete just grow in areas that no other species will
Back
Gause's competitive exclusion principle
Front
If two species have the same niche they cannot remain for long in the same habitat. One will lose out and be eliminated (or at least reduced to a very small population.)
Back
interspecific competition
Front
Species competing against another species
Back
intraspecific competition consequences
Front
leads to density-dependent birth and death rates; the effects of intraspecific competition on any individual is greater the more competitors there are
Back
character displacement
Front
Species evolve non-overlapping traits to avoid competition
Back
intraspecific competition
Front
competition between members of the same species
Back
interspecific competition consequences
Front
competition between individuals of different
species, but birth and death rates of one species vary with the population density of the other species, and vice versa
