between the enriched and reference cattail habitats. This relationship has been

documented in other aquatic systems in Florida (Newman and Reddy, 1992; Wright and

Reddy, 2001b). Benthic PHO was correlated to the nutrient parameters TN, TOC, and

TP, while soil PHO was negatively correlated with TOC and TP.

 Neither benthic or soil CBH activity were significantly different between habitats

or along the gradient. As with BGL, there were no trends evident among the habitats or

any consistent relationship with the gradient. Benthic CBH was significantly correlated

with BGL, PHO, and LEU. There were no significant correlations among enzymes in the

soil layer (Table 3-3). Benthic CBH was correlated to the nutrient parameters TN and

TP. No significant correlations between CBH and nutrient parameters were observed in

the soil layer.

 Cattail and open water benthic LEU was significantly higher at the enriched sites.

Open water and sawgrass soil layer LEU was significantly higher at the enriched sites.

Sawgrass LEU was lower (p<0.05) than the other habitats at the enriched sites. Benthic

LEU was significantly correlated with BGL, PHO, and CBH (Table 3-3), while soil layer

LEU was correlated with PHO and PHE (Table 3-4). Benthic LEU was higher than soil

layer activities in the enriched sites, however this relationship was mixed at the reference

sites. Benthic LEU was negatively correlated to the nutrient parameters TN, TOC, and

TP while the soil LEU was negatively correlated with TOC and TP.

 Phenol oxidase did not vary significantly between habitats or along the gradient.

Standard errors were greater in the PHE assays than the hydrolytic assays, consistent with

higher variability reported by Sinsabaugh (personal communication). Activities were
