Ecosystem, Abiotic, and Biotic Responses – Comparison Among
Individual Models
In general, outcomes of the ecosystem and biotic response models were
more alike than either was to the abiotic response model. The ecosystem
and biotic response models performed similarly, and shared similar sets
of significant predictors (Table 1), including the three most important
predictors (leaf area index, softwood basal area, and normalized
vegetation difference index). The cumulative contribution of abiotic,
biotic, and geographic predictors to each model (Figure 4) differed; yet
again the ecosystem and biotic response models showed commonalities,
particularly with the large relative contribution biotic predictors made
to these formulations. I-spline functions for these two latter models
also revealed parallels. Comparable curve inflections were apparent
between canopy height, leaf area index, softwood basal area, and
hardwood basal area I-splines (Figure 3).
