Predicting biotic responses to future climate warming with classic ecogeographic rules

Area of Science:

• Ecology and evolutionary biology
• Climate change biology

Background:

• Global warming is a key aspect of future environmental change, necessitating predictions of species' responses.
• Ecogeographic rules, derived from natural observations and physiological principles, offer predictive power for species adaptation.
• Established rules like Bergmann's rule are well-known, but others also provide valuable insights.

Purpose of the Study:

• To highlight the utility of multiple ecogeographic rules as predictive tools for understanding species' responses to warming.
• To emphasize the importance of considering established biological rules in the context of climate change.

Main Methods:

• Review and synthesis of established ecogeographic rules related to temperature.
• Consideration of findings from recent ecological and physiological literature.
• Reference to meta-analytical studies examining the applicability of these rules across taxa and environments.

Main Results:

• Bergmann's rule (smaller body size in warmer climates) is a prominent example.
• Six additional temperature-related rules (Allen's, Gloger's, Hesse's, Jordan's, Rapoport's, and Thorson's) are relevant predictive tools.
• Meta-analyses confirm the applicability of these rules across diverse species and environmental conditions.

Conclusions:

• Ecogeographic rules provide a robust framework for predicting biological responses to global warming.
• A suite of temperature-related rules, beyond Bergmann's, can be effectively applied to anticipate ecological and physiological adaptations.
• These rules are valuable for understanding and forecasting biodiversity changes under future climate scenarios.
