This current research reports the characterization of fibers from Posidonia oceanica L. (P. oceanica) for interest in usability as additive biomaterial polymer-based materials. The results revealed that cellulose content, density, and average fiber diameter P. were 45.35%, 1.15 g/cm3 238.41 μm, respectively. maximum degradation temperature, char yield activations energy found to be 318.8 ºC, 31...

Translocation of 13C and 15N was investigated at the spatial scales of within-shoot (i.e. the seagrass clonal unit including leaves and associated vertical rhizome) and among-shoots in a mixed meadow of Posidonia sinuosa and P. australis. Incubation with 13C and 15N was conducted in either the oldest leaf of a shoot (i.e. within-shoot scale) or in the first shoot on the 4th or 5th branch of the...

Seagrasses form extensive meadows in shallow coastal waters and are among the world's most productive ecosystems. Seagrasses can produce both clonally and sexually, and flowering has long been considered infrequent, but important for maintaining genetically diverse stands. Here we investigate the molecular mechanisms involved in flowering of the seagrass Posidonia oceanica, an iconic species en...

Abstract We present a 3-dimensional fully natural sonic crystal composed of spherical aggregates fibers (called Aegagropilae) resulting from the decomposition Posidonia Oceanica. The fiber network is first acoustically characterized, providing insights on this entanglement due to turbulent flow. Aegagropilae are then arranged principal cubic lattice. band diagram and topology structure analyzed...

Spatial modelling is an emerging approach to the management of coastal marine habitats, as it helps understanding and predicting the results of global change. This paper reviews critically two recent examples developed in Liguria, an administrative region of NW Italy. The first example, aiming at predicting habitat status depending on human pressures (i.e. anthropogenic activities capable of pr...

The effect of diatoms of the genus Cocconeis on the sex reversal of the shrimp Hippolyte inermis Leach was examined in the laboratory. Randomised experiments were carried out to investigate the functional response of shrimps to various diets. The benthic diatom Cocconeis neothumensis was offered, alternatively, during the larval phase and during the postlarval phase, and the results obtained wi...
