The incidence of specimens with lordotic, kyphotic or scoliotic
bends in their vertebral column tended to increase with increasing
levels of total VA in enriched rotifers, although this trend was not
significant (R=0.564, P=0.056) due to the large variability of
replicates. Similarly, no significant differences could be detected
between experimental groups (ANOVA, PN0.05; Figs. 8a, 9).
