See Fig. 4 and Table 7 for PCA results and the text for an explanation of the fatty acid nomenclature. Larva and stemflow main effects are compared on the sample days indicated. Arrows in parentheses next to significant or marginally significant probability values indicate an increase (↑) or a decrease (↓) in the FAME group due to the main effect. Total n = 8 for each variable on day 7, and n = 15 or 16 for each variable on days 14 and 21.
