Establishment of ecological functions in transplanted meadows of the seagrass Posidonia australis
… ecological functions establish in transplanted Posidonia australis meadows of Oyster Harbour, Western Australia, and to determine how transplanting factors (e.g. planting density, patch size and patch shape) may influence these processes. The study has also determined whether monitoring the …

Characterising responses of the seagrass Posidonia Sinuosa to changes in light availability
… motivated this characterisation of responses of Posidonia sinuosa Cambridge et Kuo to light availability and their application as monitoring tools. The study comprised of three major components: an assessment of P. sinuosa characteristics across a depthrelated gradient in long-term light …

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 …

Changes to the distribution of Posidonia seagrass communities of James Point, in response to the development of Cockburn Sound, Western Australia
… and how this development significantly reduced Posidonia seagrass meadows. Original aerial photographs of Cockburn Sound in 5 year intervals since 1948 were used, and the study area of James Point was mapped to establish spatial and temporal patterns in Posidonia seagrass meadows. These patterns …

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 …
