Biodiversity in changing environments: An external-driver internal-topology framework to guide intervention.

Area of Science:

• Ecology
• Conservation Biology
• Environmental Science

Background:

• The climate crisis is paralleled by an escalating biodiversity crisis.
• Rapid biodiversity reorganization due to global environmental change challenges conservation and restoration efforts.
• Predicting and managing these shifts necessitates conceptual and practical innovation.

Purpose of the Study:

• To develop a framework for generalizing biodiversity change at the community level.
• To understand when ecological systems maintain integrity versus collapse under abiotic change.
• To translate ecological understanding into actionable conservation and restoration decisions.

Main Methods:

• Framing community reorganization as the modulation of external abiotic drivers on internal species interaction topology.
• Utilizing plant-plant interactions in terrestrial communities as a model system.
• Exploring the translation of species abundance and trait data into management decisions.

Main Results:

• The external-driver internal-topology (EDIT) framework provides a method to capture general biodiversity patterns.
• This framework aids in understanding system integrity, collapse, and restructuring.
• It offers a template for guiding conservation and restoration interventions.

Conclusions:

• The EDIT framework helps generalize biodiversity responses to environmental change.
• It facilitates informed decision-making for conservation and restoration.
• This approach supports enhancing ecological resilience and adaptation in dynamic environments.
