Figure 3. Per species Partial Least Squares –
Discriminant Analysis plots of the metabolites found in the foliar
metabolomes of Geranium pratense, Leucanthemum vulgare,
and Ranunculus acris control or herbivore-induced plants as part
of the (a – c) plant-plant interaction experiment and (d – f)
plant-soil interaction experiment. Control plants are displayed in
orange squares. Induced plants are displayed in violet circles. Ellipses
represent the 95% confidence interval. The metabolite intensity matrix
was log+1 transformed for the purpose of data normalization. Statistical
parameters resulting from a permutational multivariate analysis of
variance using distance matrices. Abbreviations: F = pseudo-F-value; p =
p-value; expl. var = explained variance.
