BACKGROUND The seagrass Posidonia oceanica L. Delile, commonly known as Neptune grass, is an endemic species of the Mediterranean Sea. It hosts a distinctive and diverse epiphytic community, dominated by various macroalgal and animal organisms. Mediterranean bryozoans have been extensively studied but quantitative data assessing temporal and spatial variability have rarely been documented. In L...

Electron transport rate (ETR) calculations require values of irradiance, effective quantum yield of chlorophyll fluorescence (DF=F0 m), the distribution of energy between PSII and PSI and leaf-specific photosynthetic absorptance. We conducted virtually simultaneous replicated measurements of diel changes in DF=F0 m of Posidonia australis in situ, and determined leaf-specific photosynthetic abso...

Posidonia oceanica (L.) Delile meadows are recognized as priority habitat for conservation by the EU Habitats Directive. The La Maddalena Archipelago National Park (Mediterranean Sea) P. oceanica meadow, the dominant coastal habitat of the area, is mostly threatened by boat anchoring. 12 years after the establishment of mooring fields and anchoring restrictions, a study was conducted to measure...

The stationary volumetric elastic modulus (epsilon(s)) of the leaf cells of three seagrasses (Halophila ovalis (R.Br.) Hook, Zostera capricorni Aschers, and Posidonia australis Hook f.) was evaluated from estimates of epsilon(s) plus intracellular osmotic pressure (epsilon(s) + II(i)) and II(i). The estimates of (epsilon(s) + II(i)) were made using a linear displacement transducer to measure ve...
