Analyses of variation in nodulation and growth performance from the within-host inoculation trial (Experiment I) where each legume species was only inoculated with its own (sympatric) rhizobial strains.

<p>For the two phylotype level comparisons, analyses focused on subsets of hosts and rhizobial strains with sufficient representation (see Methods). <i>Z</i> statistics are given for random effects and <i>F</i> statistics for fixed effects.
