    • Predator Gut Isotopes - Characterizing ecosystem role of sharks

    Metadata Updated: October 18, 2025

    This work uses white muscle tissues collected from sixgill and sevengill sharks to characterize the diet of each species. Tissues from prey species have also been prepared in order to initialize the models. We used mixing models to determine the probabilities of each prey species being in the diet of these top predators. These data will be used to predict which prey groups are impacted by these species, and then used in conjunction with patterns of daily, seasonal, and annual movement patterns to examine the variation in predatory impact across space and time among the various prey groups. Shark tissue stable isotope signatures from Northeast Pacific coastal habitats.
