John M. Dwyer, Richard J. Hobbs, Margaret M. Mayfield. 2014. Specific leaf area responses to environmental gradients through space and time. Ecology 95:399–410. http://dx.doi.org/10.1890/13-0412.1

Appendix B. Summaries of specific-leaf-area-environment models.

Table B1. Summaries of SLA-environment models. Parameter estimates are provided for all terms retained in the most supported model for each species. Also shown for each species are the number observations in each model, the AICc weight (indicated support for the selected model relative to all candidate models), the within-site residual variance, R² values for each model level and variance components (percentage of total variance) for each model level. Coefficients for "year" indicate intercept shifts for the wetter year (2011). "NA" indicates the variable was not included in the most supported model, whereas "not tested" indicates the variable was not included in any candidate model for the species. GSP = growing season precipitation (mm). Asterisks indicate non-native species.
