Fig. 4. Comparison of means for dehydrogenase activity in detritus samples from the three sampling areas and six major vegetation communities in the spatial study. C, Cladium; C-W, Cladium and woody mix; O, others; P, Panicum; T, Typha; and T-W, Typha and woody mix. Values are means of 29 sites from each area, and 18 (C), 10 (C-W), 23 (O), 10 (P), 14 (T), and 12 (T-W) sites from each vegetation class. Different letters indicate significant differences (
< 0.05). Dashed line indicates mean for all samples.
