Exam 13: Interspecific Competition

If a species has a broad niche for several key factors it is known as a(n)

________ competition results from the behavioural exclusion of some individuals by others from a specific space that is defended.

The Russian biologist G. Gause was one of the first to support the Lotka-Volterra equations by studying the competitive interactions of ________.

The portion of potential resources and conditions that an organism actually exploits as a result of interactions with other species is its

The findings of a laboratory study are more useful and applicable than the results of a field study.

The portion of the fundamental niche that an organism actually exploits in the presence of competitors is called its ________ niche.

________ competition results when non-territorial behavioural interactions between two species result in negative effects on both species.

How can a disturbance influence interspecific competition?

________ competition occurs when the occupation by one sessile individual precludes the establishment by others.

Interspecific ________ is where the competition for space influences access to food and nesting sites.

In long-lived individuals, increasing biomass in favourable years to help mitigate interspecific competition during unfavourable years is known as

A shift in a species' morphology, behaviour, or physiology in response to resource competition is referred to as ________.

Interspecific competition through the exploitation of a shared resource is sometimes referred to as ________ competition.

Explain how the outcome of competition between two species is a function of both species and environmental characteristics.

The expansion of a species' niche in response to the removal of competition is referred to as competitive release.

The ________ principle states that two "complete competitors" cannot coexist.

Explain the significance between generalists and specialists when describing niche compression and competitive release.

The diagonal line that represents dN/dt = 0 in the graphical depiction of the Lotka-Volterra competitions equations is called

________ studied the competitive interactions of several Paramecium species and supported the Lotka-Volterra competition models.

Climatic variation can have both density-dependent and density-independent effects on populations.
