The effects of salinity on the embryonic and larvae stage of Crassostrea iredalei were investigated. Fertilised eggs and one day old D-larvae were subjected to salinities ranging from 0 to 30 ppt at temperature of 30±2°C. At salinity lower than 10 ppt, 100% mortality was observed. For embryo development, the highest survival was observed at salinity 25 ppt with 80.9±2.2% survival with no signif...

Rising sea levels threaten coastal safety by increasing the risk of flooding. Coastal dunes provide a natural form of coastal protection. Understanding drivers that constrain early development of dunes is necessary to assess whether dune development may keep pace with sea-level rise. In this study, we explored to what extent salt stress experienced by dune building plant species constrains thei...

An extremely haloalkaliphilic archaeon Natrinema sp. SSBJUP-1 showing potent amylolytic and proteolytic activities was isolated from the saline alkaline Lonar Lake, India. Amylase and protease were active over the neutral to alkaline pH range from 6 to 9. Amylase was more stable over a narrower temperature range of 40-60C than the protease but had the higher optimum (55C) for activity. By contr...

Future sea surface salinity missions will require Lband radiometers to have calibration stabilities of ≤ 0.05 K over 2 days. This research program has focused on determining the optimum radiometer requirements and configuration to achieve this objective. System configuration and component performance have been evaluated with radiometer test beds at both JPL and GSFC. The GSFC testbed uses a cry...

Zinc has previously been reported to alleviate salinity stress in plants. In this study, we monitored various biomass and chlorophyll fluorescence parameters to determine the optimum zinc sulfate concentration that can be used as foliar spray to alleviate salinity stress in Glycine soja. The plants subjected to a series of salinity levels (NaCl concentration of 0, 100, 200, and 300 mmol L), app...

Optimum concentrations of anesthetic clove oil and anesthetic lidocaine-HCl were determined for a species of adult marine medaka, Oryzias dancena, over a range of salinity conditions, and investigated in a transport simulation experiment by analyzing various water and physiological parameters. Research indicated that the higher the concentration of anesthetic at each salinity, the shorter the a...

the engineering properties of soils are generally affected by parameters such as mineral type, structure, and pore water salinity. the existing solutes of soil play a role in the electrochemical forces between particles and can change the index and mechanical properties of soil, including cohesion, compressibility, and compactibility. this study investigated the effect of sodium chloride, sodiu...

germination stage is an important stage of plant growth stage that often is affected by environmental stress including water and salinity stresses including drought and salinity. in order to study germination characteristics of scrophularia striatain water and salinity stress conditions at different temperatures an experiment was conducted. temperatures regimes included 5, 10, 15, 20, 25, 30 an...

laboratory and greenhouse experiments were conducted to determine the effects of drought and salinity stress, temperature, ph and soil depth on rye germination and emergence in gorgan university of agricultural science and natural resources. optimum temperature for germination between 25 to 34.51   oc and base and ceiling temperatures were estimated as 3.3 and 40   oc, respectively. this volunt...
