Table 1 Principal Components Analysis of the vertical biomass distribution of Daphnia. The eigenvectors of the first three principal components (PC1–PC3) account for more than 95 % of the total variation. Bold numbers depict major contrasts. The bottom line shows the cumulative percentage of the total variation explained by an individual PC.
