Abstract Marine microalgae often live in a fluctuating environment including decrease salinity caused by global warming induced sea ice melting and freshwater inflows. Under conditions of salinity, have evolved variety survival mechanisms such as lipid accumulation remodeling. The purpose this study was to investigated the membrane remodeling marine green microalga Dunaliella tertiolecta short-...

laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. factors evaluated were lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 ds cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). the maximum germination in salinity stres...

In this study, we investigate the relative ability of least square algorithm to retrieve sea surface salinity (SSS) from MODIS satellite data. We also examine with comprehensive comparison of the root mean square of bias the difference between second polynomial order algorithm and least square algorithm. Both the least squares algorithm and second polynomial order algorithm are used to retrieve...

Seagrasses worldwide are commonly infected by endophytic protists of the genus Labyrinthula. To date, the nature of the interaction of endophyte and host is not well understood. In eelgrass Zostera marina, the endophyte Labyrinthula zosterae may become virulent (pathogenic) and lead to the loss of entire seagrass beds. One of the best known examples of any marine epidemic was a series of outbre...

Upwelling events can occur in most of the oceans altering the water physical, chemical and sediment conditions and consequently the species communities dwelling the areas. For better understanding the behavior of populations inhabiting upwelling regions, the spatial and temporal distribution of a Penaeoidea shrimp was studied correlating it with the abiotic factors that vary during upwelling an...

The effect of salinity on growth, photosynthetic performance and osmotic acclimation was investigated in the eulittoral red algal species Bangiopsis subsimplex (Stylonematophyceae). The strain grew in a broad salinity range between 1 and 70 psu showing optimum growth between 10 and 50 psu. The saturation point Ik of the photosynthesis irradiance curves ranged between 153 and 83 μmol photons m s...

[1] The Soil Moisture and Ocean Salinity (SMOS) mission was selected in May 1999 by the European Space Agency to provide global and frequent soil moisture and sea surface salinity maps. SMOS’ single payload is Microwave Imaging Radiometer by Aperture Synthesis (MIRAS), an L band two-dimensional aperture synthesis interferometric radiometer with multiangular observation capabilities. Most geophy...
