DNA-metabarcoding reveals the importance of gelatinous zooplankton in the diet of Pandalus borealis, a keystone species in the Arctic

Paulina Urban, Kim Præbel, Shripathi Bhat, Jan Dierking & Owen S. Wangensteen
Information about the dietary composition of species is crucial to understand their position and role in the food web. Stomach content analysis (SCA) and stable isotope analysis (SIA) are commonly used to study marine trophic relationships. SCA can provide high taxonomic resolution but requires taxonomic expertise and frequently underestimates digestible taxa. SIA provides a time-integrated view of the dietary sources but often lacks in taxonomic resolution. The use of molecular approaches such as DNA-metabarcoding may...
