Figure 3.

Dice similarity of DGGE banding patterns at sites at Lake I-8 in summer 2003–2007. Error bars are standard error of the mean. Solid columns show average pair-wise similarity among communities at each site (inlet, lake, outlet) across sampling dates. Stippled columns show average pair-wise similarities between communities at different sites sampled on the same day. “Inlet” designates the I-8 inlet stream, “outlet” designates the outlet stream, and “lake” designates samples collected from the lake water column at the I-8 West station.
