AB Seagrasses form one of the most productive and threatened ecosystems worldwidebecause of global change and anthropogenic pressures. The frequency of extreme climaticevents, such as heat waves, are expected to increase and may drive even more adverseeffects than gradual warming. This study explores for the first time the effects of a suddenand temporary increase of temperature in situ on carbon metabolism and dissolved organiccarbon (DOC) fluxes in a community dominated by a seagrass (Cymodocea nodosa) duringtwo contrasting seasons (winter and summer). Results showed a positive correlationbetween temperature and seagrass production between seasons, while the experimentalsudden and temporary increase in water temperature did not produce significant differencesin carbon community metabolism and DOC fluxes in winter. In contrast, high temperatureconditions in summer enhanced significantly the net community production and affectedpositively to DOC fluxes. Hence, this study indicates that a sudden and temporary increasein water temperature, which characterize marine heat waves, in temperate areas mayenhance the autotrophic metabolism of seagrass communities and can yield an increase inthe DOC released, in contrast to previous researches suggesting solely negative effects onseagrasses.
