Kiyoshi Sasaki, David Lesbarréres, Glen Watson, and Jacqueline Litzgus. 2015. Mining-caused changes to habitat structure affect amphibian and reptile population ecology more than metal pollution. Ecological Applications 25:2240–2254. http://dx.doi.org/10.1890/14-1418.1
Appendix C. Independent and joint contributions of environmental variables to the explained variance for diversities of amphibians and reptiles.
Table C1. Hierarchical partitioning of environmental predictors of diversities in amphibians and reptiles at two grain sizes. Independent (I) and joint (J) contributions are shown as a percentage of the total independent contribution associated with the predictor variables. Significant independent contributions (i.e., 500 randomization-based z-scores ≥ 1.65) are shown in bold and marginal significant ones are underlined. CAN, canopy cover; CWD, the amount of coarse woody debris; Ts, soil temperature; RH, relative humidity.
