Model application niche analysis: Assessing the transferability and generalizability of ecological models

Area of Science:

• Ecological modeling
• Environmental management
• Conservation biology

Background:

• Ecological models are increasingly used for environmental management and decision-making.
• Transferring existing models to new sites is common due to resource limitations, but risks misapplication.
• Existing methods for improving model generalizability during development are insufficient for evaluating transfer risks.

Purpose of the Study:

• To propose a novel method for describing a model's application niche to aid in model selection during transfers.
• To provide a framework for evaluating the potential for unintentional misapplication of ecological models.
• To enhance transparency and consistency in model selection practices for ecological applications.

Main Methods:

• Developed a method to describe a model's application niche using synthesized information from databases and past studies.
• Utilized model performance curves and heat maps to visualize and assess model applicability.
• Demonstrated the method using an empirical model for plant community ecological condition in riverine wetlands.

Main Results:

• Assessed the transferability and generalizability of the empirical model across different geographic scales and wetland types.
• The proposed methodology provides a quantitative approach to evaluating model suitability for new environments.
• Highlighted critical steps for developing consistent and transparent model selection practices.

Conclusions:

• The proposed application niche method aids in selecting appropriate models for new sites, reducing misapplication risks.
• This approach supports informed decision-making in environmental management by clarifying model limitations.
• Further research into consistent practices for ecological model transfer and selection is warranted.
