AB Non-structural carbohydrates (NSCs) are energetic compounds that can be accumulated intissues and mobilized during periods of unfavorable conditions to maintain the biological functionsof plants. The balance of these biochemical compounds is controlled by environmental factors suchas temperature and irradiance. Zostera noltei and Zostera marina find one of their southern distributionlimits in southern Spain, where relatively high seawater temperatures are reached during summer(23–24 ◦C). To better understand the effects of elevated temperatures on the concentration of NSCs,we conducted a seasonal study at Cadiz Bay, representing warm-adapted populations of these species.Our results showed a bimodal pattern in both species, with the highest NSC content observed inDecember and June, followed by a depletion in March and August. In addition, the NSC contentobserved in the leaves of Z. noltei (71.26 ± 30.77 mg g−1 dry weight) was higher than in the rhizomesand roots (52.14 ± 38.86 mg g−1 DW). The observed patterns suggest that these species accumulatedNSCs to cope with periods of unfavorable environmental conditions. We also suggest that the limitedconcentration of NSCs in Z. noltei rhizomes and roots indicates that this population may be sufferingphysiological stress.
