Eco-evolutionary dynamics of structured populations in periodically fluctuating environments: a G function approach

Area of Science:

• Ecology
• Evolutionary Biology
• Mathematical Biology

Background:

• Understanding population dynamics is crucial for ecological and evolutionary studies.
• Existing models often fail to accurately simulate structured populations, especially under changing environmental conditions.

Purpose of the Study:

• To develop an improved eco-evolutionary modeling framework for structured populations.
• To enhance the simulation accuracy of population dynamics under fluctuating environments.

Main Methods:

• The study modifies a previous G function modeling framework.
• It incorporates principles from periodic differential equations.
• A new definition of fitness is proposed, suitable for dynamic environments.

Main Results:

• The modified approach allows for more accurate eco-evolutionary simulations in fluctuating environments.
• A toy model demonstrating life history trade-offs was used for illustration.

Conclusions:

• This novel modeling approach provides a more robust tool for studying eco-evolutionary dynamics in structured populations.
• The method's generality makes it applicable to diverse biological contexts and environmental conditions.
