The composition and structure of epipelic and planktonic algal communities in Shelter Valley Creek, Ontario, was studied for 1 year. The overall assemblage consisted of 388 taxa of which 321 were Bacillariophyceae. On the sediments, seasonal succession and community structure was, with some exceptions, typical of a hard-water stream in the northern temperate zone. Taxa that occurred frequently throughout the year were Achnanthes minutissima Kütz., Cocconeis placentula var. euglypta (Ehr.) Cl., Gomphonema olivaceum var. balticum Cl., and Navicula tripunctata (O. F. Müller) Bory. The planktonic community was, for the most part, derived from the benthos. Herbivorous grazing by larval sea lamprey, Petromyzon marinus (Pisces: Cyclostomata) did not noticeably affect algal numbers in either the plankton or sediments.Sixty-six taxa are reported as new occurrences in southern Ontario.

“…Eutrophic, hardwater lakes often show similar diatom assemblages, but Oscillatoria and other cyanobacteria are usually dominant (Ward and Siebert 1963, Olive et al 1968, Wohler and Hartmann 1975, Sanger and Crow1 1979. In a review of the early Ohio phytoplankton literature, Palmer (1962) found similar results, and also showed that abundant genera in my own study (Svnedra, Diatomq, Dinobrvon, and Mouaeotia) were sometimes dominant in smaller, lentic systems.…”

The Springtime Phytoplankton of Two Calcareous Ponds in Ohio

Limnological comparisons of two small, calcareous ponds in central Ohio were made during the spring of 1982, with weekly samples of phytoplankton and physicochemical parameters. Golden-brown algae consistently dominated both ponds. Differences in phytoplankton assemblages between the ponds were quantitative (relative abundance) rather than qualitative (genera composition) and probably resulted from differences in alkalinity and silica levels. Although generic diversity of phytoplankton increased during the spring in both ponds, assemblage structure was consistent among weeks because of the continued dominance of the same algal genera. Diversity, multivariate, and other analyses at the genera level were useful and complimentary methods for describing these plankton assemblages. A review of literature, however, suggests that use of higher taxonomic levels may be more useful for examining biotic integrity of lentic ecosystems, because the complexity of biotic and abiotic factors controlling algal composition makes species-or genus-level analyses intractable and inefficient for assessing waterquality problems.

“…However, algal density is much lower in natural rivers. It varies from a few hundred to a few thousand cells per milliliter, but peak production can reach 100,000 cells ml −1 (Aykulu, 1978;Jones and Barrington, 1985;Palmer, 1964). The maximum cell density of algae in the River Derwent was 3,800 cells ml −1 (Jones and Barrington, 1985), 6,625 cells ml −1 in River Avon (Aykulu, 1978), and 40,000-50,000 cells ml −1 in the Stour and Severn rivers in England (Swale, 1969).…”

Palmer (1964) studied algae production in fifteen North American rivers and listed the highest algal concentration in Arkansas, with a peak density at 101,200 cells ml −1 , followed by the Mississippi River with an algal concentration of 53,000 cells ml −1 . In our study, the algal density levels of 35,000 to 175,000 cells ml −1 were certainly comparable to those in natural rivers.…”
