Our new method of otolith metabolic proxy is released today in the journal “Communications Biology” from Nature. We are excited to demonstrate how we use stable carbon isotope values recorded in otoliths to reconstruct fish field metabolic rate. Our study provides the first high-resolution metabolic rate estimates for fish in the field. Moreover, our approach now allows researchers to make use of the large archives of otoliths systematically collected for more than 100 years in order to investigate historical and contemporary changes to fish physiology.
