Author Institution: Department of Biological Sciences, Kent State University, Kent, Ohio 44240A qualitative survey of algae was made during June and September, 1967, in three tributaries of the Cuyahoga River in Geauga County: West Branch, East Branch, and Tare Creek. Sixty-four species of algae found in this survey are reported here. Eight species which were collected at the majority of the 14 stations sampled are Cladophora glomerata, Aphanochaete repens, Rhizoclonium hieroglyphicum, Euglena gracilis, Vaucheria sessilis, Tribonema bombycinum, Oscillatoria nigra, and O. limosa

RHODES AND ANTHONY J. TERZIS Vol. 70system in Geauga County, Ohio. The objective of this study was a qualitativetaxonomic survey of the summer algal flora in three tributaries of this river system.HABITATSThe upper Cuyahoga River watershed lies wholly in Geauga County, Ohio.The algal flora was studied on a qualitative basis at a total of 14 stations on threetributaries of this river, four stations on West Branch, six stations on East Branch,and four stations on Tare Creek (fig. 1). At these sites, scrappings from sub-merged rock and logs, samples from algal mats entangled in weeds and twigs,and benthic samples from the mud and sand surfaces of the stream beds werecollected. Benthic samples were obtained by using a 34-incn ID glass tubeattached to rubber tubing terminated by a squeeze bulb. Collections were madein June and September, 1967. Temperature and pH were recorded at eachstation1 at the time of collection.Taxonomic identifications of both living and preserved material were basedon keys developed by Prescott (1962) and by Bourrelly (1966). Species ofOedogonium, Spirogyra, and Mougeotia were identified when sexually reproductivematerial was available. If no sexually reproductive material was present, thelatter three genera were identified only as "sp.". Samples for future referencewere preserved in a solution of 10 g potassium chrom alum and 5 ml formaldehydein 500 ml of water (Cavanaugh, 1956).RESULTS AND DISCUSSIONTemperatures at all stations at the time of collecting in June, 1967, rangedfrom 14 to 17°C. The range in September was from 20 to 23°C. The pH atall stations during the collecting periods in both June and September varied from6.8 to 7.2. Since there were no extreme variations in either temperature or pHduring this time, the details of these data for each station are not presented here.The results of this survey have been drawn together in Table 1, the algaegrouped by division, followed by the substrate on which each taxon was found.Cladophora glomerata, Aphanochaete repens, Rhizoclonium hieroglyphicum, Euglenagracilis, Vaucheria sessilis, Tribonema bombycinum, Oscillatoria nigra, and 0. limosawere collected at 7 or more of the 14 stations sampled. In the benthic communitiessampled, there was usually a single dominant macroscopic development of eitherCladophora, Chara, Nitella, Batrachospermum, Chaetophora incrassata, or Oscilla-toria. Euglena and Phacus were commonly encountered in the benthic mud andsand samples. On rock and wood surfaces, there was also usually a single dominantform of either Stigeoclonium, Cladophora, Vaucheria, Chaetophora pisiformis,Spirogyra, or Oscillatoria.A comparison between the filamentous algae found in the upper CuyahogaRiver watershed and in the west end of Lake Erie (Tiffany, 1937) showed thatof the 34 species of filamentous algae identified in this survey, 56 per cent were alsoreported by Tiffany. Stigeoclonium lubricum, Ulothrix tenerrima, Draparnaldiaglomerata, Chaetophora incrassata, Aphanochaete repens, Schizomeris leibleinii, andOscillatoria limosa, found to occur in the west end of Lake Erie (Tiffany, 1937)and the upper Cuyahoga River watershed, have also been reported from thepiedmont region of North Carolina (Whitford and Schumacher, 1963; 1969).The most ubiquitous filamentous alga found in this survey was Cladophoraglomerata, recorded at 10 of the 14 stations. Blum (1956, p. 327) states that"C. glomerata appears to be the most abundant filamentous alga in streams through-out the world." Butcher (1940) reports Cladophora from the River Hull, York-shire, England, which had a pH of 7.5 and 180 ppm of CaCO3. Orr (1969) foundan average HC03~ concentration of 92 ppm in the upper Cuyahoga River atstations where Cladophora was present. In contrast, Whitford and Schumacher(1963) found no Cladophora in soft-water streams having a HCO3~ concentrationNo. 5 SOME ALGAE IN GEAUGA CO., OHIO 297AKRONRESERVOIRLA DUERESERVOIRFIGURE 1.

RHODES AND ANTHONY J. TERZIS Vol. 70of only 20 ppm. They suggested that the absence of Cladophora in the floraof North Carolina was due to the differences in the hardness of the stream waterthere, in contrast to that of streams farther north. Our results do not negatethe conclusion of Whitford and Schumacher. Scenedesmus dimorphus, Pediastrumduplex, P. boryanum, Coelastrum microporum, Synura uvella, Merismopedia glauca,and Euglena spirogyra, non-filamentous algae identified in the upper CuyahogaRiver watershed, have also been found in surveys of phytoplankton in regions ofthe eastern United States (Reinhard, 1931; Palmer, 1932; Tiffany, 1934; Whitford,1958).TABLE 1Algae identified from collections taken from three tributaries of the CuyahogaRiver, June and September, 1967, Algae are grouped by division; substrates onwhich each taxon was found are given following its name, abbreviated as follows:rock—ro, wood—wo, stream bed—b, weeds—we, twigs—tw.ChlorophytaAphanochaete repens A.
