Environmental factors controlling biomass development of seagrass meadows of Zostera noltei after a drastic decline (Arcachon Bay, France) ArchiMer
Cognat, Mathis; Ganthy, Florian; Auby, Isabelle; Barraquand, Frederic; Rigouin, Loic; Sottolichio, Aldo.
The relative impact of light, depth, hydrology, hydrodynamics, sediment and nutrients on growth of the seagrass Zostera noltei was investigated in Arcachon Bay, where the extent of seagrass beds has been decreasing for 20 years. A comprehensive multi-parameter survey of 9 sites was conducted monthly over one year. A three-parameter logistic growth model was fitted to biomass data to unravel the relative contributions of environmental factors on seagrass growth. The present study highlights the fact that, in addition to the dominant positive effect of light on plant growth, the hydrological and hydrodynamic parameters were important drivers for Z. noltei growth at the scale of the whole Bay. At the scale of individual sites, other factors such as macroalgal...

European Marine Observation Data Network - EMODnet Physics ArchiMer
Novellino, Antonio; D'Angelo, Paolo; Benedetti, Giacomo; Manzella, Giuseppe; Gorringe, Patrick; Schaap, Dick; Pouliquen, Sylvie; Rickards, Lesley.
The EMODnet - Physics is a Marine Observation and Data Information System that provides a single point of access to near real time and historical achieved data. It is includes systems for physical data from the whole Europe (wave height and period, temperature of the water column, wind speed and direction, salinity of the water column, horizontal velocity of the water column, light attenuation, and sea level) as monitored by fixed stations, ARGO floats, drifting buoys, gliders, and ferry-boxes. It does provide discovering of data sets (both near real time and historical data sets), viewing and free and open downloading of the data from more than 4400 platforms. Moreover, the system provides full interoperability with third-party software through WMS...

Relationship Between Parameters of Development and Functional Compounds of Yacon Leaves BABT
Ferreira,Bruna Mayara Roldão; Dagostin,João Luiz Andreotti; Andrade,Eriel Forville de; Takashina,Thiago Atsushi; Ellendersen,Luciana de Souza Neves; Masson,Maria Lucia.
Abstract Yacon is a tuberous root from the Andean region being increasingly grown across the world due to the low caloric values of their roots and the functional properties of extractions of its leaves. However, there is still a gap in the knowledge of how the plant develops, and if physical and chemical changes are noticed regarding maturity. The subject of this work was to investigate the dynamics of a group of parameters and to establish correlations across them. To achieve this goal, leaves collected from three different parts of the plant in three months were assessed regarding size (plant height and leaf area), color and the presence of sesquiterpene lactones. Different methods of extraction were also studied and the total phenolic content was...
