THE ALGAL FLORA OF THE CAMPUS OF BRIGHAM YOUNG UNIVERSITY, PROVO, UTAH Cheng Mou-Sheng' and Samuel R. Rushforth' Abstract.— The algal flora of the Brigham Young University campus is more diverse than previously thought. Sixty-eight genera containing 160 species of Chlorophyta, Euglenophyta, Chrysophyta, and Cyanophyta were col- lected and identified. The greatest number of species was obtained from a small pond in the arboretum, with progressively fewer species obtained in the irrigation canal partly surrounding the campus and in specialized hab- itats in the greenhouses.

As a consequence, the first proposed classification schemes assigned the filamentous and parenchymatous taxa to the green algal order Chaetophorales sensu Wille. The introduction of ultrastructural and molecular methods provided novel insight into algal evolution and generated taxonomic revisions based on phylogenetic inference. However, until now, the number of molecular phylogenetic studies focusing on the Chaetophorales s.s. is surprisingly low. To enhance knowledge about phylogenetic

  • Shoreline Algae of Western Lake Erie1
    THE OHIO JOURNAL OF SCIENCE Vol. 70 SEPTEMBER, 1970 ' No. 5 SHORELINE ALGAE OF WESTERN LAKE ERIE1 RACHEL COX DOWNING2 Graduate Studies in Botany, The Ohio State University, Columbus, Ohio J/.3210 ABSTRACT The algae of western Lake Erie have been extensively studied for more than 70 years, but, until the present study by the author, conducted between April and October, 1967, almost nothing was known of the shoreline as a specific algal habitat. A total of 61 taxa were identified from the shorelines. The importance of this habitat is very clear from the results of this study, for, of the 61 taxa found, 39 are new records for western Lake Erie, and one, Arnoldiella conchophila Miller, appears to be a new United States record, having been previously reported only from central Russia. Western Lake Erie has been the site of extensive phycological research since 1898. After some 70 years of algal study, it would be reasonable to assume that all the various habitats would have been thoroughly studied and reported on, but when reports of research were compiled by Dr. Clarence E. Taft for a taxonomic summary, it became apparent that the shoreline had been neglected. Considerable information on the algae of the ponds, marshes, swamps, quarry ponds, open lake, inlets, ditches, and canals has been reported on by individuals and by agencies doing research, and by the algae classes at the Franz Theodore Stone Laboratory, Put-in-Bay, Ohio. Papers containing this information are by Jennings (1900), Pieters (1902), Snow (1902), Stehle (1923), Tiffany and Ahlstrom (1931), Ahlstrom and Tiffany (1934), Tiffany (1934 and 1937), Chandler (1940), Taft (1940 and 1942), Daily (1942 and 1945), Taft (1945 and 1946), Wood (1947), Curl (1951), McMilliam (1951), Verduin (1952), Wright (1955), Normanden and Taft (1959), Taft (1964a and 1964b), and Taft and Kishler (1968).

  • The Occurrence of the Green Alga Prododerma Viride (Chlorophyceae) in Michigan
    2017 THE GREAT LAKES BOTANIST 201 THE OCCURRENCE OF THE GREEN ALGA PRODODERMA VIRIDE (CHLOROPHYCEAE) IN MICHIGAN Daniel E. Wujek Department of Biology Central Michigan University Mt. Pleasant, MI 48859 ABSTRACT The epiphytic branched filamentous green alga Protoderma viride is reported from Michigan for the first time. An alga occurring worldwide, its only other report for the Great Lakes region is from Wisconsin. Using light microscopy it was observed from numerous strata from one Upper Peninsula site and several Lower Peninsula locations. INTRODUCTION The widely occurring green algal genus Protoderma K¸tzing has been re - ported from all seven continents and the Pacific Ocean islands (Burova et al. 2011, Guiry 2016). Of the nine species currently accepted taxonomically (six freshwater, three marine; Guiry 2016) only the species Protoderma viride K¸tzing has been reported from as many as six continents, though it is not known from Antarctica. Considering that it is the most widely distributed species of Protoderma (Guiry 2016), it is surprising that it has never been reported from Michigan. The only previous record of its occurrence from the Great Lakes re - gion is from Wisconsin (Prescott 1962). METHODS AND MATERIALS More than 30 samples containing Protoderma viride were collected throughout Michigan over a 32-years period (summer months 1971ñ2002). The environments from which the collections were taken ranged from lotic to lentic and from shaded to bright light. Protoderma viride K¸tzing was found variously on rocks, pebbles, and macrophytes (e.g., Potamogeton spp., Sagittaria spp., Typha latifolia, and Valisneria americana) or other filamentous algae (e.g., Chaetophora spp., Cladophora glomerata, Oedogonium spp., and Rhizoclonium).
