to study the interaction effect of the salinity and salicylic acid on some morphological and physiological traits in clary sage (salvia sclarea), a pot experiment was conducted as factorial based on a completely randomized design with three levels of nacl and control (zero, 50, 100 and 150 mm), as the first factor and three levels of spraying the solution of salicylic acid and control (zero, 10...

Live specimens of benthic foraminiferal species Rosalina leei were subjected to a combination of temperature (25° C, 30° C and 35° C) and salinity (25‰, 30‰ and 35‰) to assess its differential response to the annual range of seawater temperature and salinity reported at the sampling site. A total of 216 specimens were used for the experiment. Within the range of temperature and salinity, to whi...

OBJECTIVES: The objectives of this study were to (1) summarize published literature on biological perchlorate/nitrate destruction; (2) perform bench-scale tests to characterize biodegradation parameters (i.e., salinity, pH, temperature, nutrients, electron donor, etc.), improve perchlorate/nitrate destruction rates, and evaluate mechanisms to generate and retain biomass; and (3) validate bench-...

a knowledge of soil surface conditions, especially desert crust, salt crust and desert varnish is useful for improving classification of remotely sensed data. desert crust can generate high levels of reflectance, similar to those areas with high salt concentration and non-saline soil. therefore, soil surface crusts might bias thematic remote sensing of soils. in this study, we evaluated the eff...

A major problem of arid and semi-arid regions is environmental stresses like salinity and drought. To study the effect of Artichoke germination under different levels of salinity and drought, two separate experiments were performed. The experimental treatments included different salinity levels of NaCl (0, 50, 100, 150 mM) and five drought levels by PEG (0, 10%, 15%, 20% and 25%) with three rep...

Both rainfall and wind have acoustic signatures that can be discerned at depths in the ocean well below the sea surface. We examine observations of rainfall and wind speed collected at a depth of 600 m in the Bay of Bengal from a specially modified Argo profiling float. In addition to the normal Argo sensors, the float carried a passive acoustic listener sensor package that monitored the spectr...
