Outputs of species-level phylogenetic mixed-effect models.

<p>Phylogenetic mixed-effects models were fitted in brms [<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3002927#pbio.3002927.ref044" target="_blank">44</a>] to examine the effect of genome size (GS) on the change in a species’ percent cover with N, P fertilization. In addition to the model outlined in <b><a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3002927#pbio.3002927.t002" target="_blank">Table 2</a></b>, a model was fitted to include the interaction between the above factors and plant functional group (<b>a,</b> <i>n</i> = 439). Another model was also run for grass species only, with photosynthetic pathway include as an additional explanatory variable (<b>b</b>, <i>n</i> = 72). Lastly, a model was run as in <b><a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.3002927#pbio.3002927.t002" target="_blank">Table 2</a></b> but only including species for which direct GS measurements were available (<b>c</b>, <i>n</i> = 172). Estimated intercepts and slope values showing a slope with nonzero 95% credible intervals are highlighted in bold.</p> <p>(DOCX)</p>
