Table 3.
The influence of three strongest factors from analysis of particular species (according to explanatory power) on Impatiens fitness. D.f., residual degrees of freedom; E.V. total, variability explained by the model. For effects direction and explained variability by the particular factor [see Supporting Information—Tables S1–S4]. For the explanation of response variables see Table 2; factors are described in Methods.
