Exam 13: Interspecific Competition

Explain how it is possible for a diversity of potential competitors to coexist in the same community, despite the competitive exclusion principle.

The ________ equations predict the outcomes of interspecific competition under different conditions.

Explain what is meant by a transplant experiment.

The outcome of interspecific competition varies with environmental changes over time but does not vary over space.

Interactions among species are always negative.

When two organisms use a portion of the same resource simultaneously, it is referred to as

Which of the following is NOT expected following competition?

________ competition results when nonterritorial behavioural interactions between species result in negative effects on one or both species.

Competition in which the occupation of space by one individual prevents establishment in that space by another individual is referred to as ________ competition.

The biologist G. F. Gause conducted experiments with Paramecium that supported the predictions of the Lotka-Volterra competition models.

Competition rarely influences the evolution of species' niches.

In theory, when two species compete for the same resources, ________ will result.

The ________ coefficients represent the per capita effect of an individual of one species on the other.

The competitive ability of a species remains constant even when environmental conditions change.

Describe the competitive exclusion principle and outline its major assumptions. Provide an example of a scientific study that supports the competitive exclusion principle.

Give several examples to illustrate how temporal and spatial variation in the environment can influence the outcome of competition.
