2.) Determine the relationships between nutrient conditions and microbial enzyme activities among all four hydrologic units of the Everglades. 3.) Determine the validity of different enzyme models in predicting potential decomposition among different litter qualities and in varying nutrient conditions. 4.) Determine the effects of a simulated drought on enzyme activities in WCA- 3A and ENP-Taylor Slough (ENP-TS) cores. The overall hypotheses for this study were: (i) Deeper water slough habitats exhibit accelerated potential decomposition due to substrate quality differences; (ii) Nutrient loading generally enhances microbial enzyme activities; and (iii) Decreased water levels result in an enhancement of enzyme activities, suggesting greater potential decomposition based on perceived soil quality.
