Copepod Assemblages in A Large Arctic Coastal Area: A Baseline Summer Study
To provide a baseline description of copepod assemblages in the Pechora Sea, an estuarine area with great economical and ecological importance, we conducted a survey during the summer season. A total of 24 copepod taxa were identified in the study, with Acartia longiremis , Calanus finmarchicus , Ce...
