a slight trendgold
In contrast, according to predictions of the best model, leaf sugar concentration showed a slight trend of increasing over the course of the experiment in all sites ( Supplementary Table 13 ) and leaves of seagrasses from low impacted sites around Ischia had significantly higher leaf sugar concentration than plants from Baia by the end of the experiment [ Figure 5 ; χ 2 (1) = 4.53, p = 0.0333; Supplementary Table 12A ].
