Mutualisms in a warming world

Area of Science:

• Ecology
• Evolutionary Biology
• Physiology

Background:

• Mutualisms are crucial for species survival and reproduction, yet predicting climate change impacts is challenging due to species-specific traits.
• Thermal ecology offers physiological and mechanistic insights vital for understanding species' responses to environmental change.

Purpose of the Study:

• To develop a conceptual and quantitative framework connecting thermal physiology, species traits, and mutualistic interactions.
• To create metrics for assessing the thermal performance of mutualisms under changing global temperatures.

Main Methods:

• Integrating thermal physiology with species' functional and life history traits.
• Developing metrics to quantify the thermal performance of interacting species' traits.
• Assessing how warming interacts with resource availability to affect mutualistic associations.

Main Results:

• Identified temperature-dependent traits as key drivers of reciprocal mutualism functioning.
• Developed novel metrics to approximate the thermal performance of mutualisms.
• Showcased how warming and resource availability can interact to influence species associations.

Conclusions:

• The proposed framework provides a baseline for predicting global warming impacts on mutualisms.
• This approach integrates physiological mechanisms with ecological interactions across scales.
• Highlights the need to consider thermal physiology in conservation strategies for mutualistic species.
