Competitive exclusion principle

Front

Gause, 1934 — if two species, with the same needs, coexist in the same ecosystem, then one will be excluded from the community due to intense competition If 2 competing species can coexist if they have different needs

Back

Competitive exclusion

Front

one species out competes and drives out the other — no two species can coexist if they need the environment in the same way

Back

Chemical interaction

Front

inhibits or kills other species

Back

encounter

Front

nonterritorial

Back

How do species deal with negative effects of competition?

Front

leave and find new area, go extinct, co-exist in smaller populations, evolve to exploit different niche

Back

Inter-specific competition

Front

members of different species are competing for the same resources one species is usually harmed

Back

benthic

Front

invertebrates found on lake bottoms

Back

Fundamental niche

Front

Hutchinson, niche is a quantifiable characteristic of a species Range of axis variables: the limits required for a species to survive, reproduce

Back

Resource partitioning

Front

the different species coexist because they need different sources

Back

Ecological niche

Front

all of the reproduce and habitat requirements of a species describes the space and diet requirements of a species

Back

Territorial interaction

Front

behavior of one species excludes another

Back

limnetic

Front

invertebrates found on water surface

Back

Fundamental ecological niche

Front

total conditions, tolerances, and requirements of an organism

Back

Realized niche

Front

combination of conditions and resources need to exist in the presence of other competing species no two occurring species may have exactly the same realized niche

Back

Preemption

Front

occupation by one species prohibits another from taking or colonizing

Back

Intra-specific competition

Front

individuals are competing with other members of the same species for food, space, resources

Back

Consumption

Front

one species monopolizes a shared food resource
