Appendix D. Model selection tables for consumer response magnitude analyses.
| TABLE D1. All thirty-two combinations of five explanatory categorical variables (R = response mechanism, S = ecosystem subtype, T = ecosystem type, P = consumer trophic position, and L = resource trophic level) and one grouping factor (s = system) explaining the regression between the resource pulse ratio and the consumer response ratio. Models within the 95% confidence set are shown in italics. |
