Dry Bulk Density = Dry Weight of Core (g) Volume of Core (cm3) A conversion factor was established for each soil core based on the percent soil moisture of the subsample. This conversion factor was then used to calculate the dry weight of the core: Dry Weight of Core (g) = Wet Weight of Core (g) Water Weight of Core (g), where Water Weight of Core (g) = Wet Weight of Core (g) x % Soil Moisture. The core volume was calculated using the formula for the volume of a cylinder: Core Volume (cm3) = B x r2 x 1, where r = radius (cm) and 1 = length (cm). Organic Matter Percent organic matter was calculated using the formula: % Organic Matter = (Oven Dry Weight (g) Ashed Oven Dry Weight (g)) x 100 Oven Dry Weight (g). MinitabTM Statistical Software was used to construct a multiple regression comparing soil moisture (%), dry soil bulk density (g/cm3), and soil organic matter (%). MinitabTM Statistical Software was also used to perform a Spearman correlation coefficient for rooted vines, soil moisture (%), and plant nutrients (g/m3), as described by Eddison (2000) and Brown (1998). The Spearman correlation coefficient is an adaptation from the Pearson product-moment correlation coefficient where normality cannot be assumed. SIMULATION MODELING A temporal computer simulation model, was developed to mimic large scale successional trends and contributions of vine species in reclaimed forested wetlands. The model was developed to consider organizational processes and long-term successional changes and was calibrated with data from field measurements. Systems Ecology Language The first step in the creation of this model was diagramming the constructed forested wetland system (Figure 6.1) and aggregating the system to a scale which has the fundamental nature of the system that portrays the theories to be tested (Figure 6.5).
