Flashcards in Interspecific Competition 1 Deck (10):
1

Define coexistence.

To exist together at the same time or in the same place.

2

Define niche.

The animals place in the biotic environment.

3

Define competitive exclusion.

When one species prevents all members of another species from utilising a resource and the inferior competitor goes locally extinct.

4

Define character displacement.

Alteration of morphology of a species as a result of the presence of interspecific competitors.

5

Define competition.

The contest for an essential resource by neighbouring individuals that are exploiting the same finite supply.

6

What is the species-redundancy hypothesis?

Maybe all species are so similar in what they do in a community, doesn't matter if any/many are lost?

7

Define competitive release.

The expansion of a niche in the absence of a competitor.

8

Define fundamental niche.

The total range of environmental conditions suitable for existence in the absence of any competition.

9

Define realised niche.

The environmental conditions suitable for existence along with competition.

10

Define character displacement.

Alteration of morphology of a species as a result of the presence of interspecific competitors.
