Effects of bottom depth and water clarity on the vertical distribution of Calanus spp

Several Calanus species occupy depths spanning from <100 m to several thousand meters during winter. Here, we report that variations in bottom depth and water clarity accounted for most of the variation in the mean depth of early winter Calanus spp. distributions of Norwegian fjords. We suggest a...

Description
Summary:Several Calanus species occupy depths spanning from <100 m to several thousand meters during winter. Here, we report that variations in bottom depth and water clarity accounted for most of the variation in the mean depth of early winter Calanus spp. distributions of Norwegian fjords. We suggest a modification of a previously proposed hypothesis (<cross-ref type="bib" refid="FBR096C17">Miller et al ., 1991</cross-ref>) on how light affects the winter distribution of Calanus finmarchicus .
