Description

Rogers and four co-authors measure isotope factors in Pacific cod for diet modeling, in work from twenty twenty-three. Stable isotope analysis traces what fish eat from chemical signatures in tissue. Models need an accurate offset value between diet and tissue, called a discrimination factor.

That offset may shift with water temperature and diet quality, both changing under climate change. The team derived the factors experimentally under varied conditions in the lab. Carbon and nitrogen isotopes were tracked separately. Climate informed factors will keep future diet models for this commercial fish honest as oceans warm.
