As the season progresses, in the periphyton in the macrophyte beds, community dominance shifts from euglenophyte to diatoms.
All sites were dominated by green algae and euglenophytes by number of individuals.
Front sites were dominated by diatoms nearly exclusively; however, euglenophytes and small green algae are also important contributors to the community volume.
All periphyton communities were dominated by diatoms--which composed 48 percent of the community volume, with green algae (30 percent) and euglenophytes (18 percent) also making large contributions to the community volume.
The high volume during the 1993 vernal peak was largely due to euglenophytes.
However, in sharp contrast to Casamatta and others, who found that Cyanobacteria and Cryptopytes dominated, we, like Klarer and Millie (1992), found that diatoms and Euglenophytes dominate at Old Woman Creek.
However, in this experiment the euglenophytes and diatoms (primarily Cyclotella) were significantly enhanced by gizzard shad, in contrast to the effects observed in the sediment-feeding experiment.
Another phylum of protoctists living in conditions similar to the euglenophytes is the small group of raphidophytes ***, represented mainly by the genus Chattonella, which probably includes some species first described by the generic names of Olisthodis-cus and Hornellia.
Flore pratique des Algues d'eau douce de Belgique, 2 Pyrrhophytes, Raphidophytes, Euglenophytes.
The phytoplankton assemblage observed in Gull Lake during the three study summers was quite diverse and included diatoms (especially Cyclotella), Chrysophytes (especially Dinobryon), Chlorophytes (especially Sphaerocystis and Oocystis), Cryptophytes (especially Cryptomonas), Cyanobacteria (especially Anacystis, Chroococcus), Euglenophytes (especially Trachelomonas), Pyrrhyophyta (especially Peridinium), and numerous unidentified microflagellates.
