Figure 1: A map of the study area on the Tallapoosa River, AL. Sampling locations are indicated with filled, black circles.
Figure 2: Proportion by number of the sampled fish assemblage belonging to each family collected from four sites on the Tallapoosa River, AL. Site abbreviations are as defined in Table 1.
Figure 3: (a) Multidimensional scaling ordinations of CPE by site and season for fishes captured from four sites in the Tallapoosa River. Site abbreviations are as defined in Table 1. (b) The distribution of permuted delta values from a multiresponse permutation procedure. The dashed line to the left represents the observed delta.
Figure 4: Kendall’s tau correlations with nonmetric multidimensional scaling ordination axes for individual species CPE data from the Tallapoosa River upstream and downstream of Harris Dam. Species abbreviations are as defined in Table 2 and dashed lines represent zero on the MDS axes.
Figure 5: Site clusters based on between – and within – site dissimilarity for sites on the Tallapoosa River, AL. Branches hang to within-group dissimilarity while horizontal lines are positioned at among-group dissimilarities. Site abbreviations are as defined in Table 1.
