David M. Costello, Matt J. Michel. 2013. Predator-induced defenses in tadpoles confound body stoichiometry predictions of the general stress paradigm. Ecology 94:2229–2236. http://dx.doi.org/10.1890/12-2251.1
Appendix C. AIC tables for models predicting differences in tadpole stoichiometry.
Table C1. Result of AICc analysis of candidate models predicting predator-mediated differences in tadpole whole organism N:P. Each candidate model includes sibship (random effect) and a single predictor variable (fixed effect) for either size corrected measures of tadpole morphology, composite morphology measures derived from principal components (PC) analysis, or tadpole behavior.
