Thomas W. Baribault, Richard K. Kobe, and Andrew O. Finley. 2012. Tropical tree growth is correlated with soil phosphorus, potassium, and calcium, though not for legumes. Ecological Monographs 82:189–203. http://dx.doi.org/10.1890/11-1013.1

Appendix D (Table D1). Results of fitting models of individual tree growth as a function of diameter, soil resources, and neighborhood index for species for which more than 50 focal individuals were available. Total variance explained by supported models is compared to the diameter-only model to identify any additional variance explained by neighborhood or resources (Add. Var.). If the best supported model is the diameter-only model, then no additional variance can be explained by other factors.
