The Plankton of the St. Croix River in 2000, Including Tardigrades, a Red Alga, and Chrysophyceae

We studied the St. Croix River from May to September 2000, sampling the water with surface plankton net tows. We found low water, low flow, and a warm environment and observed new surface plankton. We report a red alga. The surface plankton also contained the alga genera Oedegonium , Hydrodictyon ,...

Summary:We studied the St. Croix River from May to September 2000, sampling the water with surface plankton net tows. We found low water, low flow, and a warm environment and observed new surface plankton. We report a red alga. The surface plankton also contained the alga genera Oedegonium , Hydrodictyon , Elakatothrix , Selenastrum , Tetraedon , Ouadrigula , and Xanthidinium for the first time in our years of study. We also observed Synura , a chrysophyte, which had not been observed previously. We found many suctorian and amoeboid forms in the plankton, and we report the first continuous surface plankton observations of tardigrades.
