Abstract
Recurrent group analysis of the Bay of Fundy and southwest Nova Scotia regions on 40 species of zooplankton were compared on a seasonal and annual basis. One major recurrent group occurred per region. Six and five core species occurred in the Bay of Fundy and southwest Nova Scotian waters, respectively. Of these core species, Sagitta elegans, Calanus finmarchicus, and Metridia lucens were common to both areas. The interconnection of the Bay of Fundy and southwest Nova Scotia zooplankton communities is relatively strong (75% of core species for either area occurred in the other area in three of the four surveys). All core species were endemic and boreal.
