Student Project Figures Figure 4 Fig. 3: The average percentage of Didemnum spp. colony coverage of plates within an ARMS unit. over a short (nine-week) and long (year-long) period. The short bar is represented by white and the long bar is grey. Each bar is the is represents the mean of three replicates, with the dots being the individual data points. Each data point is the average colony cover for only Didemnum spp. containing plates within the ARMS unit. The error bars represent the standard error of each treatment. Figure 3 Figure 4
