Disturbance theory for ecosystem ecologists: A primer.

Area of Science:

• Ecology
• Global Change Biology
• Ecosystem Science

Background:

• Ecosystem disturbance theories predate current global change challenges.
• Existing theories lack modern ecological metrics and interdisciplinary insights.
• Global change necessitates updated understanding of ecosystem functional responses.

Purpose of the Study:

• To present four key disturbance ecology concepts for ecosystem ecologists.
• To highlight the need for integrating knowledge from various biological disciplines.
• To advance the analysis of ecosystem functional responses to disturbance.

Main Methods:

• Review and synthesis of disturbance ecology concepts.
• Integration of theories from population, community, and ecosystem ecology.
• Conceptual framework development for analyzing disturbance impacts.

Main Results:

• Four critical concepts: response directionality, functional thresholds, disturbance-succession interactions, and diversity-stability relationships.
• Integration of population and community ecology enhances understanding of thresholds and succession.
• Recognizing disturbance's varied effects (promote, inhibit, change) is crucial.

Conclusions:

• Interdisciplinary approaches are essential for advancing ecosystem functional response to disturbance.
• Updated theoretical and analytical frameworks are needed for global change research.
• Integrating diverse biological knowledge improves interpretation of ecosystem dynamics.
