Barriers to adaptive reasoning in community ecology

Area of Science:

• Community ecology
• Evolutionary biology
• Phenotypic adaptation

Background:

• Recent calls advocate for a trait-focused approach in community ecology.
• This shift necessitates integrating evolutionary reasoning into ecological research.
• Current ecological thought is dominated by the ecosystem concept, potentially hindering this integration.

Purpose of the Study:

• To explore the challenges and necessity of a trait-focused approach in community ecology.
• To emphasize the importance of evolutionary reasoning and adaptation in ecological predictions.
• To argue for placing adaptation at the center of ecological research.

Main Methods:

• Conceptual analysis of community ecology's historical development and current paradigms.
• Discussion of practical and theoretical challenges in defining and identifying adaptations.
• Examination of scaling effects and hierarchical processes influencing trait-environment correlations.

Main Results:

• A trait-focused approach can enhance ecological predictions and open new research avenues.
• Significant challenges exist, including historical disciplinary roots, the dominance of the ecosystem concept, defining adaptations, and scaling effects.
• Overcoming these challenges requires a fundamental shift in ecological research philosophy.

Conclusions:

• Predicting future ecological conditions necessitates a central role for the concept of adaptation.
• Integrating adaptation across sub-disciplines is key to advancing community ecology as a predictive science.
• A paradigm shift towards evolutionary reasoning is essential for ecological progress.
