Every biological process is highly dependent on temperature. This applies to the very small, the very large, and every scale in between, from molecules to ecosystems and in every environment. A general theory explaining how life depends on temperature is lacking — until recently. In a paper published in the Proceedings of the National Academy of Sciences, researchers led by Jose Ignacio Arroyo, a Santa Fe Institute Postdoctoral Fellow, introduce a simple framework that strictly predicts how temperature affects living things, at all scales. “This is very basic,” says SFI External Professor Pablo Marquet, an ecologist at the Pontifica Universidad Catolica de Chile, in Santiago. Marquet, Ph.D. thesis advisor, is also working on the model. “You can apply this to almost any process that is affected by temperature. We hope this will be an important contribution.” Marquet noted that such a theory could help researchers make accurate predictions in a variety of areas, including biologica

A new general theory for temperature dependence in biology developed by the Santa Fe Institute could help researchers make accurate predictions in a variety of fields, including biological responses to climate change, the spread of infectious diseases, and food production.
