Seawater carbonate chemistry, structural and chemical characteristics of the seagrass Thalassia testudinum in an situ CO2 enrichment experiment

Seagrasses commonly display carbon-limited photosynthetic rates. Thus, increases in atmospheric pCO2, and consequentially oceanic CO2(aq) concentrations, may prove beneficial. While addressed in mesocosms, these hypotheses have not been tested in the field with manipulative experimentation. This study examines the effects of in situ CO2(aq) enrichment on the structural and chemical characteristics of the tropical seagrass, Thalassia testudinum. CO2(aq) availability was manipulated for 6 months in clear, open-top chambers within a shallow seagrass meadow in the Florida Keys (USA), reproducing forecasts for the year 2100. Structural characteristics (leaf area, leaf growth, shoot mass, and shoot density) were unresponsive to CO2(aq) enrichment. However, leaf nitrogen and phosphorus content declined on average by 11 and 21 %, respectively. Belowground, non-structural carbohydrates increased by 29 %. These results indicate that increased CO2(aq) availability may primarily alter the chemical composition of seagrasses, influencing both the nutrient status and resilience of these systems.

Sur la présence de l'Enhalus acoroide (L.f.) Roem. et Schultes au littoral du Viêtnam

In the "Flore Générale de l'Indochine" three species of phanerogams have been described: Halophila ovalis (R. Br.) Hook. f., Diplanthera uninervis (Forsk.) Aschers. and Ruppia rostella Koch in Rchb. In 1954, Dawson added to this list Halophila Beccari Aschers. and Thalassia hemprichii (Ehrenb.) Aschers. Even Mr. Feldmann found in the herbarium of the Oceanographic Institute of Nha-Trang, the Cymodocea rotundata (Ehrenb. & Hernpr.) Asch. & Schweinf., that the authors found in Cua-Be (Nha trang), Qui-Nhon and Da-Nang (Tourane).
