ANOVA for effects of litter effects on plant performance.

<p>Litter effects from exotic versus native plant species (Litter) on germination or (in the case of <i>Rorippa</i>) sprouting rates and plant biomass production as well as the differences between exotic and native plant species (Plant) within three genera (<i>Artemisia</i>, <i>Rorippa</i>, and <i>Senecio</i>).</p>1<p>Numerator d.f. is 1 for all factors. Denominator d.f. is 16, except for Rorippa-pair where denominator d.f. is 14.
