[1] Salinity profiles collected by the International Argo Project (International Argo Project data are available at http://argo.jcommops.org) since 2000 provide us an unprecedented opportunity to study impacts of salinity data on the quality of ocean analysis, which has been hampered by a lack of salinity observations historically. The operational Global Ocean Data Assimilation System (GODAS) d...

Invasive species are commonly thought to have broad tolerances that enable them to colonize new habitats, but this assumption has rarely been tested. In particular, the relative importance of acclimation (plasticity) and adaptation for invasion success are poorly understood. This study examined effects of short-term and developmental acclimation on adult salinity tolerance in the copepod Euryte...

In order to investigate the effects of irrigation water salinity on root traits and absorption of sodium (Na+) and potassium (K+) by wheat cultivars, a factorial experiment, based on completely randomized design with 3 replications, was ‎conducted under greenhouse conditions. The main factor was 7 wheat genotypes ]Ghods, Marvdasht and Bahar (sensitive to salinity) and Arg, Bam, Sistani and Sing...

salinity stress is one of the most important abiotic factors that restrict the growth and yield of many plants. salinity can increasingly influence the host susceptibility, occurrence and development of plant diseases due to its negative effects on the host plants. mycorrhizal fungi are able to increase the tolerance of some plants to salinity. in this study, the biological effects of glomus mo...

Salinity is a limiting factor in agricultural production that inflicts great damages on agricultural products. In order to decrease or stop salinity stress, numerous methods are proposed by different researchers. One of the methods to reduce the damages of salinity stress is cultivating tolerant plants to salinity. In this research, resistance of three radish cultivars to salinity stress was in...

Objective of this study was to evaluation Changes in proline, catalase and germination characteristics of barley seeds under salinity stress. Salinity stress at osmotic potentials of 0 (as control), 4, -8, -12 and -16 bar were adjusted using NaCl before the start of the experiment. Our results showed that, the effect of salinity levels for all traits was significantly. With, increases of salini...
