[1] The Columbia River plume (CRP) is an ecologically important source of nutrients, pollutants, and fresh water to the Oregon/Washington shelf. It is traditionally undersampled, with observations constrained to ships or moorings. High-spatialand temporal-resolution observations afforded by satellites would increase sampling if the plume could be quantitatively detected in the imagery. Two empi...

Excessive soil salinity is a major ecological and agronomical problem, the adverse effects of which are becoming a serious issue in regions where saline water is used for irrigation. Plants can employ regulatory strategies, such as DNA methylation, to enable relatively rapid adaptation to new conditions. In this regard, cytosine methylation might play an integral role in the regulation of gene ...

The Pacific white shrimp Litopenaeus vannamei is a euryhaline penaeid species that shows ontogenetic adaptations to salinity, with its larvae inhabiting oceanic environments and postlarvae and juveniles inhabiting estuaries and lagoons. Ontogenetic adaptations to salinity manifest in L. vannamei through strong hyper-osmoregulatory and hypo-osmoregulatory patterns and an ability to tolerate extr...

INTRODUCTION Salinity is one of the major abiotic stresses affecting crop production via adverse effects of osmotic stress, specific ion toxicity, and stress-related nutritional disorders. Detrimental effects of salinity are also often exacerbated by low oxygen availability when plants are grown under waterlogged conditions. Developing salinity-tolerant varieties is critical to overcome these p...

The benthic stages of Dreissenidae and Mytilidae may be dispersed over long distances while attached to ship hulls. Alternatively, larvae may be transported by water currents and in the ballast and bilge water of ships and vessels. To gain insight into dispersal potential and habitat suitability, survival of the benthic stages of two invasive dreissenid species (Dreissena polymorpha and Mytilop...

Increases in abscisic acid (ABA) concentrations in plant tissues correlate with growth inhibition in salt-stressed plants. Therefore, it was hypothesized that Arabidopsis ABA mutants different in, or insensitive to, ABA would respond differently than wild type (wt) to salinity stress. Seeds (wt, abi1-1, abi2-1, abi3-1, and aba1-3) were germinated and grown hydroponically in three separate exper...

Salinity-induced modulations in growth, photosynthetic pigments, relative water content (RWC), lipid peroxidation, photosynthesis, photosystem II efficiency, and changes in activity of various antioxidative enzymes were studied in the halophyte Salvadora persica treated with various levels of salinity (0, 250, 500, 750, and 1000 mM NaCl) to obtain an insight into the salt tolerance ability of t...

The increase in soil salinity due to human-induced processes poses a severe threat agriculture on regional and global scale. Soil salinization caused by natural anthropogenic factors is vital environmental hazard, specifically semi-arid arid regions of the world. detection monitoring are critical sustainability management. current study compared performance machine learning models produce spati...

Abstract Hazard maps are essential tools to aid decision makers in land-use planning, sustainable infrastructure development, and emergency preparedness. Despite the availability of historical data, there has been no attempt produce hazard for Kuwait. In cooperation with World Bank, this study investigated natural anthropogenic hazards that affect The objective was assess face Kuwait map most c...
