Dendrogram of sample fish assemblage similarity in the Tunison Brook (TB) and Lime Hollow Creek (LH) stream reaches. LH_W indicates the LH_Wetland assemblage and N.F. indicates the fishless sample group. Fish abundances were ln-transformed and the Bray-Curtis similarity index values of each linkage is shown on the ordinate. Each asterisk (*) indicates a linkage joining two significantly different groups; boxes enclose members of each distinct assemblage.
