Only models with ΔAICc < 7 and null models are shown. We show -2 log likelihood value (-2 Loglike), number of parameters (k), AIC values, differences in AIC between best model and each candidate model (ΔAIC), AIC weights (wi) and the likelihood coefficient of determination (R2). FISHBIOWET, wet-season fish biomass; MCRIND, microtopography index; REC, recession rate; SUBMGVEG, submerged vegetation; CRAYBIODRY, dry-season crayfish biomass; GRSHBIOWET, wet-season shrimp biomass.
