No Stomach, No Problem: an Integrated Morpho-Molecular Approach to Assessing the Diets of the Cunner Wrasse, Tautogolabrus adspersus, among Coastal, Nearshore Regions of Atlantic Canada.
High biodiversity in coastal marine ecosystems allows for the formation of complex and inconspicuous trophic arrangements between a consumer and its prey community. For small omnivorous wrasses characterized by high digestion rates, these arrangements are often poorly reflected in their observable d...

High biodiversity in coastal marine ecosystems allows for the formation of complex and inconspicuous trophic arrangements between a consumer and its prey community.
