The Ability of Cladophora to Adapt to Nutrient Changes in the Watab Watershed
Over the past several years, excessive algal growth has occurred in the lakes associated with Saint John's University campus. To assess the causes of this growth, the physical, chemical and biological characteristics of Lower Stumpf Lake were monitored for approximately four months. Environmental parameters of temperature, pH, dissolved oxygen, and nutrients were assessed to determine which parameter influenced growth of the green alga Cladophora. Based on these results, controlled laboratory culture experiments were conducted to determine the nitrate and phosphate requirement and uptake for Cladophora. This alga grew well in nutrient rich Lower Stumpf Lake. However, in culture, Cladophora may have a mechanism for nutrient uptake and storage. Understanding the uptake and storage capabilities of this alga may help determine affective management strategies to improve the quality of Lower Stumpf lake.
