Figure 19. | Spatial clusters of 14 Upper Mississippi River System (UMRS) navigation pools based on
fish community structure (ranked abundance data). The two lines below
the abscissa represent the two major groups of UMRS pools. Circles
around abscissa labels represent robust groupings of spatial structure
beyond the coarse two-group designation and are based on mean Bray-Curtis
Similarity among the six study areas from 1993 to 2000 (mean represented
by the solid blue line and 95% confidence intervals represented by
the broken blue lines). LG = La Grange Pool and OR = Open River. |
