Scholarship of Discovery
The populations of two phytoplankton genera, Stigeoclonium, a green algae, and Tabellaria, a diatom were surveyed and monitored over a period of 19 months in two different freshwater quarries in North Eastern Illinois. Populations were compared by the amount of cells per milliliter. Water samples were collected at different depths and throughout the year in both quarries. The autumn season showed the largest amount of phytoplankton populations, and Tabellaria was most abundant genus. Of the two quarries sampled, the one located in an urban center had a larger abundance of algal cells. A statistically significant relationship was determined between algal cell abundance and depth, with the surface water have the largest amount of cells.
