Summary of aster model comparisons to test for effects of region and habitat on C. fasciculata lifetime seed production.

The full model included fixed effects for block, region, habitat and region × habitat with lifetime seed production, consisting of multiple life history stages (Fig. S1), as the response. Likelihood ratio tests were used to compare the fit of the full model to reduced models that sequentially dropped terms. Analysis of deviance (−2 log likelihood) and χ2P–values for each model test are listed. The block and the interaction term were tested against the full model, while the region and soil terms were tested against the model without the interaction term.
