Ecometrics: the traits that bind the past and present together

Area of Science:

• Ecology
• Evolutionary Biology
• Climate Change Science

Background:

• Understanding organismal responses to climate change is crucial.
• Current approaches often focus on species distribution and ecosystem services.
• A need exists for a more integrated, trait-based approach to study climate change biology.

Purpose of the Study:

• To present a novel, taxon-free approach called ecometrics for studying climate change biology.
• To demonstrate how measuring ecomorphological traits can reveal organism-environment interactions.
• To shift the research perspective towards understanding the reciprocal interactions between biotic systems and a changing climate.

Main Methods:

• Ecometrics involves measuring the distribution of easily quantifiable organismal traits (e.g., tooth structure, limb proportions, leaf shape).
• Traits are selected based on their close relationship between structure, function, and interaction with the local environment.
• Data are integrated across multiple spatial and temporal scales.

Main Results:

• Ecometric trait distributions serve as a universal metric for exploring system dynamics at all scales.
• This approach allows for quantitative analysis of how biotic systems interact with changing climate.
• It facilitates understanding of climate change impacts on interactions within the biotic-physical system.

Conclusions:

• Ecometrics provides a powerful framework for integrative climate change biology.
• This method enables a deeper understanding of organism-environment interactions under climate change.
• The IUBS program iCCB (integrative Climate Change Biology) has been initiated to advance this research area.
