The bar graphs in Fig. 3 and Fig. 5 show similar patterns in the periphyton populations found in the three locations between week one and week two. Location 1 had the least amount of periphyton with an average of 13.66 the first week and 17.67 the second week. Location 2 had the most with an average of 94.01 week one and 79 week two. And the third location falls in the middle with an average of 20.33 week one and 54.33 week two.
The pie charts in Fig. 4 and Fig. 6 show the distributions of the different types of periphyton found at the three locations. The distributions for location 1 are similar between both weeks with the difference of no oval periphyton found the second week. Location 2 shows more equal diversity between thin clear rectangles, small rectangles and slivers in the first week than in the second week where the majority is thin clear rectangles. And for location 3 there is a shift for less thin clear rectangles and more small rectangles and slivers.
