Effects of sediment sulfides on seagrass Posidonia oceanica meristematic activity
Seagrass meadows rank amongst the most productive ecosystems on Earth, growing along tropical and temperate coasts, where they have important structural and biogeochemical functions (Hemminga & Duarte 2000). Seagrasses are clonal plants, which expand into new areas vegetatively by adding modules produced by the meristems located at the rhizome apices, rendering seagrass demographics and product...
متن کاملEndophytic bacterial community of a Mediterranean marine angiosperm (Posidonia oceanica)
Bacterial endophytes are crucial for the survival of many terrestrial plants, but little is known about the presence and importance of bacterial endophytes of marine plants. We conducted a survey of the endophytic bacterial community of the long-living Mediterranean marine angiosperm Posidonia oceanica in surface-sterilized tissues (roots, rhizomes, and leaves) by Denaturing Gradient Gel Electr...
متن کاملPosidonia oceanica: a tracer of past mercury contamination.
The aim of this study is to assess the relevance and the potential of Posidonia oceanica as a tracer of past mercury contamination. Shoots were collected on two sites, an impacted site, Rosignano (Tuscany, Italy), and a pristine site, Tonnara (Corsica, France). Lepidochronology was used to measure mercury concentrations in living sheaths and in the corresponding dead sheaths. The results show t...
متن کاملDissolved organic matter release in a Posidonia oceanica meadow
We examined annual nutrient changes (nitrate, phosphate and ammonium) and the net dissolved organic carbon (DOC), nitrogen (DON) and phosphorus (DOP) release using in situ benthic incubations in a Posidonia oceanica meadow and in unvegetated sediments of Magalluf Bay (Mallorca Island, Spain) at monthly intervals. We also examined the role of the P. oceanica meadow in the C:N:P ratio transformat...
متن کاملEffect of a seagrass (Posidonia oceanica) meadow on wave propagation
We demonstrate the utility of using the equivalent bottom roughness for calculating the friction factor and the drag coefficient of a seagrass meadow for conditions in which the meadow height is small compared to the water depth. Wave attenuation induced by the seagrass Posidonia oceanica is evaluated using field data from bottom-mounted acoustic doppler veloci meters (ADVs). Using the data fro...
