Sponge Assemblages and Predicted Archetypes in the Eastern Canadian Arctic
Little information exists on the environmental requirements of sponges from the Canadian Arctic, increasing the necessity to establish baseline distribution data on sponge as - semblages to predict their susceptibility to climate change. Here we describe the sponge taxa of Hudson Strait, Ungava Bay,...
