A Survey of the Seasonal Population Patterns of Rotifers: A Comparison between the Eutrophic Conditions of Gemini Lake and the "Cleansing" effects of the Wetlands
A survey was conducted of the population dynamics of rotifers on a lake in Collegeville Township. Also, the following contrasting effects on rotifers of lake pollution and purification from a polluted lake through nearby wetlands was surveyed for a length of four months. This was coupled with an analysis of seasonal physical and chemical parameters of the mentioned aquatic environments. These included water temperature, pH, levels of nitrates and phosphates, and dissolved oxygen content. Further research involved horizontal and vertical distribution of rotifer species in the polluted lake.
The result of the survey was to demonstrate the diversity and succession of rotifer population due to eutrophic lake conditions and seasonal water temperature increases. The eutrophic Gemini Lake was initially not as diverse in rotifer populations but maintained its diversity to a greater degree than that of the Wetlands.
