Appendix B. Supplementary tables reporting replicated results for graph strength.
Table B1. Results for competing models to explain the variation in different measures of fitness (lamb production and survival) in bighorn sheep on Ram Mountain, Alberta (see Table 1). Models constructed with graph strength, see Table 3 for results using eigenvector centrality. Emboldened values represent models with ∆AIC ≤ 3.

Table B2. Model averaged results from the global model (Table B2) to explain the variation in different measures of fitness in bighorn sheep on Ram Mountain, Alberta. Models constructed with graph strength, see Tables 4 and 5 for results using eigenvector centrality. We standardized all variable to their z-scores prior to analysis. Emboldened numbers report either p < 0.05 or relative variable importance values (AICw) = 1.
