  1. The results of both multi-response and species-specific models are presented. No. of subsets: number of models generated by the pruning pass, which include a given variable; GCV: generalized cross-validation; RSS: decrease in the residual sum-of-square; R2: model’s R square. Points of occurrence: number of points in which the species was detected, out of the 75 total points surveyed in the study
