Figures & data
Figure 1. Study site locations in the Oconee River Basin, Piedmont physiographic region, Georgia, USA.
Table 1. Descriptive metrics of the five study streams located in the Piedmont region of the Upper Oconee River Watershed, Georgia, USA.
Figure 2. Cluster analysis of invertebrate communities at five streams with each month treated separately (G = Gravel, S = S, and B = Bedrock). Samples were collected in May, August, and November, 2003, and community structures for each sample reflect replicate sampling of all sub-habitats present (riffles, pools, runs, and wood).
Table 2. Average number of taxa and EPT taxa in five streams for each habitat type and for all habitats combined (Ri = riffles, Ru = runs, P = pools, and W = wood).
Figure 3. NMS ordination of sub-habitats based on invertebrate community composition. Final stress = 22.1 (for two-dimensional solution). Replicate samples were collected from riffles, runs, pools, and/or wood from five streams Gravel (G) 1, Gravel 2, Sand (S) 1, Sand 2, and Bedrock (B) 1. Collections were made in May, August, and November, 2003, and pooled (by sub-habitat) for this analysis.
