BACKGROUND Sea cucumbers (Apostichopus japonicus) are an imperiled fauna exposed to a variety of environmental condition such as salinity and studies are urgently needed to assess their effects to guide aquaculture efforts. The effects of acute salinity stress on coelomic fluid osmotic pressure, ion concentrations, the activity of Na+/K+-ATPase in respiratory trees and the histological variatio...

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...

[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...

Abstract In China, fresh water resources are scarce, while brackish abundant. Reasonable utilization of is one the important measures to alleviate contradiction shortage. order study effect irrigation on and salt transport in saline-alkali soils, one-dimensional infiltration experiments soil columns were conducted. The influence with different salinities salinized was compared analyzed. results...

Abstract The release of neodymium (Nd) from particles along continental margins may contribute to losses in the global Nd budget. Changjiang River, which carries a heavy load total suspended matter, empties into East China Sea, and strong particulate–seawater interaction process occurs salinity gradient. In low-salinity region ( S < 2.0), removal dissolved rare earth elements (dREEs) occurs,...

In this paper, Michael Boyer attempted to determine the magnitude of an emerging environmental threat: the flow of radioactive materials from industrial sites in the former Soviet Union to rivers and other bodies of water, which in turn empty into the Arctic Ocean. While such radioactive pollution is harmful regardless of its destination, the Arctic’s precarious ecology is particularly vulnerab...

BACKGROUND Because soil salinity is a major abiotic constraint affecting crop yield, much research has been conducted to develop plants with improved salinity tolerance. Salinity stress impacts many aspects of a plant's physiology, making it difficult to study in toto Instead, it is more tractable to dissect the plant's response into traits that are hypothesized to be involved in the overall to...

Contemporary agriculture is facing new challenges with the increasing population and demand for food on Earth and the decrease in crop productivity due to abiotic stresses such as water deficit, high salinity, and extreme fluctuations of temperatures. The knowledge of plant stress responses, though widely extended in recent years, is still unable to provide efficient strategies for improvement ...

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...
