Table 3. Pairwise tests of angles between body shape differences among rivers detected by four independent observers.

Measurements of angles (degrees) between bwgPC1 vectors (below the diagonal) and P-values (above the diagonal) are shown. Significant P-values (in bold) indicate that shape change vectors are similar to each other.
