where SPDN = species density, BIOM = biomass (in grams per square meter), SALT = soil salinity (in grams per kilogram), FLOOD = flooding stress (distance in centimeters above or below a standard reference elevation), SOIL = percentage soil carbon, and DIST = percentage of plot disturbed (bare mud).
For this reason, fencing and fertilization were included in the model as treatment variables (Joreskog and Sorbom 1996), and the [R.sup.2] values for SPDN and BIOM increased to 60% and 39% respectively [ILLUSTRATION FOR FIGURE 2 OMITTED].
FERT had a strong direct relationship with SPDN (path coefficient = -0.50) while its indirect effect was weaker (0.24), with a total effect of -0.27.
The path from BIOM to SPDN likely represents an underlying hump-shaped relationship, involving many processes (Gough 1996, Grace and Pugesek 1997).
