In 1P, the planktonic algae community was dominated by Bacillariophyta in winter, and all of the six classes of planktonic algae occurred in this season. Overabundance of planktonic algae can lead to fish kills in the late summer and fall. Phytoplankton are free floating, photosynthetic microorganisms found in lakes, streams, oceans. Their photosynthetic pigments are more varied than those of plants, and their cells have features not found among plants … Lilly Pads Arrowhead and Splatterdock Control. There are three main types of algae: Pithophora, Planktonic, and Filamentous Algae. Linnaeus may not have been the first to name and group organisms together but the essence of his binomial system of species names, strictly within higher hierarchical groupings based upon morphological affinities, has survived intact through over two centuries of continuous expansion and refinement. An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in freshwater or marine water systems, and is often recognized by the discoloration in the water from their pigments. The tempo-ral sequence depends on lake trophic status (Sec-tion 3.2.3; Table 3.3) with algae forming dense blooms (see Glossary) in eutrophic lakes of diatoms (Fig. Planktonic Algae.
