  <dc:description>&lt;p&gt;&lt;span&gt;In sampling throughout a year, at about 3-wk intervals, of the crustacean zooplankton discharged from Lake Superior through the St. Marys River, 30 species were collected, including three not previously recorded for the lake: the copepod&amp;nbsp;&lt;/span&gt;&lt;i&gt;Cyclops strenuus&lt;/i&gt;&lt;span&gt;, and the cladocerans&amp;nbsp;&lt;/span&gt;&lt;i&gt;Alona costata&lt;/i&gt;&lt;span&gt;&amp;nbsp;and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Alonella acutirostris&lt;/i&gt;&lt;span&gt;. Five copepods,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Cyclops bicuspidatus thomasi&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Diaptomus ashlandi&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;D&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;sicilis&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Limnocalanus macrurus&lt;/i&gt;&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Senecella calanoides&lt;/i&gt;&lt;span&gt;&amp;nbsp;were present in the plankton throughout the year while three other copepods,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Diaptomus minutus&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Epischura lacustris&lt;/i&gt;&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Mesocyclops edax&lt;/i&gt;&lt;span&gt;, along with all cladocerans, were present only during summer and fall. Five species of copepods,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Diaptomus sicilis&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;D&lt;/i&gt;&lt;span&gt;.&amp;nbsp;&lt;/span&gt;&lt;i&gt;minutus&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Limnocalanus macrurus&lt;/i&gt;&lt;span&gt;,&amp;nbsp;&lt;/span&gt;&lt;i&gt;Senecella calanoides&lt;/i&gt;&lt;span&gt;, and&amp;nbsp;&lt;/span&gt;&lt;i&gt;Epischura lacustris&lt;/i&gt;&lt;span&gt;&amp;nbsp;produced a single generation annually; three other copepods and all cladocerans produced two or more generations. All species breed 1–3 mo later in Lake Superior than in lakes Michigan and Erie.&lt;/span&gt;&lt;/p&gt;</dc:description>
