Species-specific phenotypic plasticity of two tropical seagrass species in response to in situ fertilisation under different trophic conditions

Meadow trophic status regulates the nitrogen filter function of tropical seagrasses in seasonally eutrophic coastal waters

“…in tissues (Agawin et al 1996), an altered morphology (Thomsen et al 2020(Thomsen et al , 2022, or a reduction of carbohydrate reserves in belowground biomass (Invers et al 2004). Conversely, low light availability reduces growth rates, induces the shedding of leaves, and reduces carbohydrate reserves in belowground biomass (see review by McMahon et al 2013 and references therein).…”

“…Among the consequences of eutrophication, nutrient enrichment and decreased light availability have been related to hamper seagrass performance (Herbeck et al 2014). Several indicators for elevated nitrogen exposure have been identified in seagrasses, such as an initial increase of seagrass growth (Agawin et al 1996; Terrados et al 1999), elevated total nitrogen (TN) concentrations in tissues (Agawin et al 1996), an altered morphology (Thomsen et al 2020, 2022), or a reduction of carbohydrate reserves in belowground biomass (Invers et al 2004). Conversely, low light availability reduces growth rates, induces the shedding of leaves, and reduces carbohydrate reserves in belowground biomass ( see review by McMahon et al 2013 and references therein).…”
