Theoretical Approaches in Evolutionary Ecology: Environmental Feedback as a Unifying Perspective

Area of Science:

• Theoretical evolutionary ecology
• Mathematical modeling in biology

Background:

• Evolutionary biology and ecology rely on strong theoretical foundations and diverse modeling techniques.
• A key challenge is understanding the complex feedback loop between ecological and evolutionary processes.
• Current theoretical approaches are often divided into distinct schools of thought.

Purpose of the Study:

• To synthesize different modeling approaches in evolutionary ecology.
• To highlight connections between quantitative genetics, evolutionary game theory, adaptive dynamics, and inclusive fitness theory.
• To clarify the current state of theory in evolutionary ecology by making eco-evolutionary feedback explicit.

Main Methods:

• Review and synthesis of existing theoretical frameworks in evolutionary ecology.
• Explicitly modeling the dependence of population and evolutionary dynamics on environmental dynamics.
• Analyzing the interplay between environmental feedback and process timescales.

Main Results:

• Identified two main classes of models: those jointly considering ecological and evolutionary dynamics, and those assuming timescale separation.
• Demonstrated how making environmental dynamics explicit materializes the eco-evolutionary feedback loop.
• Provided a unified perspective on theoretical evolutionary ecology.

Conclusions:

• A unified perspective on eco-evolutionary dynamics is achievable by explicitly linking ecological and evolutionary processes with environmental dynamics.
• Understanding the interplay between environmental feedback and process timescales is crucial.
• Future research should address extensions and challenges in current theoretical frameworks.
