Oil-mediated oxidative-stress responses in a keystone zooplanktonic species, Calanus finmarchicus
The copepod Calanus finmarchicus is an ecologically important species in the North Atlantic, Norwegian and Barents seas. Accidental or continuous petroleum pollution from oil and gas production in these seas may pose a significant threat to this low trophic level keystone species. Responses related...
