Fig. 3. Net effect of litter conversion into faeces on physicochemical characteristics.

Fig. 3

Net differences in principal component (PC) scores (see Fig. 2) between faeces and the leaf litter from which they were derived as a function of litter PC1 scores (a) and PC2 scores (b) for all combinations of litter and detritivore species (mean ± SE; n = 3). Differences above the black dotted lines are significantly positive, and differences below the black dashed line are significantly negative. Numbers in brackets indicate the relative frequency of non-significant differences (=), positive differences (↑) and negative differences (↓). %SS (percentage of total sum of squares) and asterisks (ns: P > 0.05; ***P < 0.001) indicate the variance and P value associated with the effect of litter quality (PC scores), detritivore species and their interaction in a two-way ANCOVA. Thick black lines represent the regression lines for all treatments, with grey areas representing the 95% confidence intervals of regression lines. Grey lines represent the regression line for each detritivore species separately, each labelled with the first two letters of the detritivore genus name.
