Database Systems for Advanced Applicationslogist recognizes the much wider coverage of the word than the “microscopic green plants” of the layman; he too is cognizant of the above connotations, but is also interested in algae as the primary producers. That interest must of necessity include those factors which influence primary production, which factors are the environment.

The Gross Classification of Algae,lass is unchanged, demanding considerable uniformity with regard to chemical and cyto-logical features and to the type of monadoid cells, while allowing for unlimited variation in thallus construction, and disregarding whether the prevailing vegetative condition is that of motile or of nonmotile cells.

Micronutrient Requirements for Green Plants, Especially Algae,ing upon whether they are utilized by higher plants or by green or blue-green algae. Plants require mineral elements for various functions. The macronutrients are used generally as building materials, whereas the micronutrients are commonly metal constituents of enzymes which enter into biological reactions (McElroy and Nason, 1954).

The Ecology of Benthic Algae,n undertaken. This preponderance of effort on the one community is hardly surprising and not unwarranted, since the phytoplankton often forms the bulk of the biomass in at least the lotic environment, and is readily sampled, cultured, and amenable to experimentation.

The Biotic Relationships within Water Blooms,on and organic pollution on the type of algae in an aquatic environment is discussed. Other factors controlling the species of algae in a bloom that are reviewed are predation by animals, attacks by bacteria or fungi, and the effects of extracellular products of certain algae in limiting the development of other species.
