Information on biotic interactions improves transferability of distribution models.

Area of Science:

• Ecology and environmental science
• Biodiversity and conservation

Background:

• Predicting species' distributions is vital for ecological research and conservation.
• Current methods often rely on climatic requirements, assuming climate is the primary driver of species ranges at large scales.
• The influence of biotic interactions on species' distributions has been difficult to reconcile with this climate-centric view.

Purpose of the Study:

• To resolve the apparent paradox between the importance of climate and biotic interactions in determining species' distributions.
• To demonstrate how biotic interactions can influence species' range margins while maintaining model transferability.
• To identify conditions under which changes in species interactions significantly alter range boundaries.

Main Methods:

• The study likely involves ecological modeling and analysis of species distribution data.
• It focuses on the interplay between climatic factors and biotic interactions.
• The methodology aims to explain model transferability in the context of ecological interactions.

Main Results:

• Biotic interactions can affect species' range margins without compromising the transferability of distribution models.
• The research provides a framework for understanding how ecological interactions contribute to species' geographical limits.
• Specific scenarios were identified where minor shifts in biotic interactions lead to substantial changes in species' ranges.

Conclusions:

• Climate and biotic interactions are not mutually exclusive in determining species' distributions; they can coexist.
• Understanding biotic interactions is crucial for accurate predictions of species' responses to environmental change.
• This work reconciles a long-standing debate in ecology, offering a more nuanced view of species' range dynamics.
