Appendix E. Standardized direct, indirect, and total effects of land-cover on each biotic response.
TABLE E1. Standardized direct, indirect, and total effects of land-cover on each biotic response. Direct effects reflect bivariate relationships whereas indirect effects calculate the influence of land-cover on biota through one or more intermediate links.
