Functional Stability Hypothesis and Ecological Diversity

Resistance, resilience, and functional stability are three different concepts related to stability in communities.

In community ecology, a community is defined as a group of single-species populations that interact directly or indirectly.

Closed community boundaries are associated with the individualistic community concept.

The relationship between diversity and stability of species composition in communities is always a cause-effect relationship.

The stability of function and diversity in communities are completely unrelated concepts.

Substitution by functional analogues is not a mechanism for stability of function in communities.

Keystone species are those that have minimal impact on the community's functionality.

The superorganism and individualistic community concepts have no contrasting features.

Ecotones are now mostly recognized as closed community boundaries.

Zonation occurs along a biological gradient in communities.
