Roots adhesion processes in the Mediterranean seagrass Posidonia oceanica
… investigates root and root hair adhesion in Posidonia oceanica seedlings and its relevance for restoration. This endemic Mediterranean seagrass delivers key ecosystem services, including carbon sequestration, sediment stabilization, and biodiversity support, yet its meadows have declined due …

Effects of Posidonia oceanica seagrass on nearshore waves and wave-induced flows.
… the effects of the large Mediterranean seagrass Posidonia oceanica on coastal waves and wave-induced flows, which has significant implications for coastal protection. Investigations were made on both a natural shallow Posidonia oceanica bed and, in controlled conditions of full-scale Posidonia …

The effect of ocean acidification on plant-animal interactions in a <i>Posidonia oceanica</i> meadow
… Mediterranean Sea, meadows of the seagrass <i>Posidonia oceanica</i> play a pivotal role in coastal systems, providing shelter and food for a highly diversified plant and animal community, and nursery for several commercial species of fish and bivalves. This thesis aims to provide a broad …

Colonisation épiphyte de Posidonia oceanica (L.) Delile: Comparaison entre des feuilles artificielles et des feuilles naturelles.
… de diagnostic rapides de ces perturbations. Posidonia oceanica (L.) Delile, qui est un des piliers de cet écosystème, a souvent été utilisée pour évaluer l’état de santé du milieu côtier méditerranéen. Cependant, comme son turnover est relativement lent et que cette plante peut accumuler des …

Evolution des herbiers à Posidonia oceanica (L.) Delile dans la baie de Calvi (Corse, France) et influence de l’ancrage dans la baie de l’Alga
… we studied the impact of human activities on Posidonia oceanica meadows in Calvi Bay (Corsica, France). We mostly focused on the consequences of boats anchoring in Alga Bay. The map of the marine habitats realized during this study shows that P. oceanica meadows cover a surface of 4.94 km2 in …

The natural recolonisation process of the seagrass Posidonia oceanica (L.) Delile after the introduction of the Italo-algerian methane pipeline in the SW Mediterranean Sea.
… process and patterns of the seagrass Posidonia oceanica after a man-induced impact. The installation of a methane pipeline connecting Italy and Tunisia destroyed a large seagrass bed in the South Mediterranean Sea (SW Sicily, Italy). Pipes were buried and backfilled using terrestrial …

Predictive modelling and coastal storm responsea study of urban and natural coastal systems
… one is characterised by the presence of seagrass Posidonia oceanica deposition on the foreshore, known as "banquette". The thesis comprehensively evaluates these models' role in predicting and mitigating coastal hazards by investigating the two different environments. The first topic addressed in …

Productivity and carbon sequestration potential of seagrass ecosystems in the eastern Aegean Sea
… CO₂ emissions. Increased fragmentation of Posidonia oceanica seagrass meadows within the eastern Mediterranean basin, linked to increased sea surface temperature, places these meadows at high risk of loss. Annual metabolism estimates showed patchy shallow water P. oceanica within the …

On the role of biomass on coastal morphodynamics in natural and urban Mediterranean beaches
… deals with the role that biomasses (mainly Posidonia oceanica and, in some cases, Arundo donax rests) have within three Mediterranean beaches differentiated from each other by more or less marked human impacts. On a beach with almost irrelevant anthropic impacts, the deposition of the …

Historical Records And Current Status Of Fucales (Cystoseira and Sargassum spp.) In The Gulf of Naples
… Cystoseira, among very dense and deep stands of Posidonia oceanica meadows in the oligotrophic waters around the island of Capri, seems to confirm this hypothesis. Another interesting result was obtained by a feeding choice experiment. The sea urchin Paracentrotus lividus fed indiscriminately on …
