Fundamental niche also limits an organism's ability to do equally well under different conditions.
|
Principle Constraint.
|
|
|
Species Interaction are Diffuse
|
The direct interactions within the community tended to be weak, making it difficult to determine the effect of any given species on another
|
|
|
When one species does not interact with a second species directly, but influences a third species that does not have a direct interaction with a second.
|
Indirect Interactions.
|
|
|
As we move across the landscape, variations in the physical environment will alter the nature of constraints on species distribution and abundance.
|
Environmental Gradiant Shape.
|
|
|
Environmental change is a direct result of the organisms within the community.
|
Autogenic.
|
|
|
Environmental change is a feature of the physical environment.
|
Allogenic.
|
|
|
Increases species richness among plants.
|
Colonization.
|
|
|
Decreases species richness among plants.
|
Species Replacement.
|
|
|
Declines as shade-tolerant tree species displace the earlier successional trees and shrubs.
|
Species Diversity.
|
|
|
The pattern of high diversity at intermediate frequencies of disturbance.
|
Intermediate Disturbance Hypothesis.
|
|
|
How do plant communities help shape animal communities?
|
Structural features of vegetation influence habitat suitability for a given species may be related to a variety of specific needs (food, cover, and nesting sites).
