Figure 4. Non-metric Multidimensional Scaling (NMDS) of microbial communities.

Figure 4

NMDS of microbial communities within each sampled lake. Circles, Barney’s Lake; squares, Fox Lake; diamonds, Lake Geneserath, triangles, Lake Michigan. Open shapes correspond to surface-water samples, while filled shapes correspond to bottom-water samples. Numbers associated with points correspond to time point of sampling. Vectors correspond to environmental variables significantly correlated (p < 0.001, R > 0.5) to separation of microbial communities within NMDS. DO, dissolved oxygen; DOC, dissolved organic carbon; Temp, temperature.
