Sedimentation that leads to periodic, and often prolonged, burial events is becoming more common on the world's coastlines as human populations expand and create urbanised marine environments. Different seagrass species react differently to sediment burial but many species in the southern hemisphere are yet to be examined. How seagrasses react to burial has restoration implications. There is a ...

Samples were collected adjacent to the Island of Porquerolles in the Northwest Mediterranean Sea to study the distribution of natural and anthropogenic radionuclides in heavily oxygen-depleted sediments associated with the decomposition of organic carbon derived from the sea grass Posidonia oceanica. Elevated isotopic concentrations of uranium ( U and U up to 200 Bq/kg d.w.) were likely due to ...

Three case studies involving two temperate Australian seagrass species – Pondweed (Ruppia tuberosa) and Ribbon Weed (Posidonia australis) highlight different approaches to their restoration. Seeds rhizomes were used in three collaborative programmes promote new scale up restoration outcomes.

This study focused on the ingestion and assimilation of Posidonia oceanica (L.) Delile litter by Gammarella fucicola Leach and Gammarus aequicauda Martynov, two dominant detritivore amphipods of the P. oceanica leaf litter. Scanning electron microscope observations indicated that leaf litter is highly colonized by diverse diatoms, bacteria and fungi, which may constitute a potential food source...

The structure of two biochars and their activated carbons was investigated by Electron Paramagnetic Resonance, Solid State Nuclear Magnetic Fourier Transform Infrared spectroscopies, together with X-ray diffraction nitrogen adsorption/desorption isotherm measurements. were obtained from wood Posidonia Oceanica slow pyrolysis up to 600 °C, whereas the prepared impregnation KOH, heating 800 °C.
