Effects of Nutrient and Light Levels on Lobophora variegata

Algal samples, which had been run through primary productivity experiments, were analyzed. Calculations were made on their surface area, dry weight, and vegetative weight and the results were entered into the computer. From this, the photosynthetic rate could be calculated and the results analyzed using SYSTAT. The algae were being tested to find significant differences between forms of Lobophora variegata under different nutrient and light conditions. This work was done for Mark and Diane Littler and Barrett Brooks. This data is part of primary productivity research done in the past on other species and is used to support the functional form theory.

This research was supported by a grant from the Educational Outreach Fund.
