The objective of this research program was to study seagrass beds characteristics under various environmental conditions in the French Antilles (FA, Caribbean Sea). A total of 61 parameters, from plant physiology to seagrass ecosystem, were tested along a gradient of anthropogenic conditions, distributed across 11 sites and 3 islands of the FA. A selection of 7 parameters was identified as relevant for the monitoring of seagrass meadows in the framework of public policies. They combined "early warning indicators" (e.g. nutrients and some trace metals) and long-term responding parameters (e.g. shoot density) adapted to management time scales. The ecological status of seagrass meadows was evaluated using a PCA. This work is a first step towards monitoring and management of seagrass meadows in the FA. specialized Biological indicators Caribbean Sea Ecological status Management Pressure-impact relationship Seagrass GUADELOUPE SAINT MARTIN SAINT BARTHELEMY PETITES ANTILLES CARAIBE MER 038 034 170 112646 [15 p.] 2021 0025-326X https://www.documentation.ird.fr/hor/fdi:010082692 10.1016/j.marpolbul.2021.112646 0025-326X [F B010082692] https://www.documentation.ird.fr/hor/fdi:010082692 https://www.documentation.ird.fr/intranet/publi/2021-09/010082692.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2021-09-17 2021-09-17 fdi:010082692 fre
