Managing terminal lake elevation and salinity are emerging problems worldwide. We contribute to terminal lake management research by quantitatively assessing water and salt flow for Utah's Great Salt Lake. In 1959, Union Pacific Railroad constructed a rock-filled causeway across the Great Salt Lake, separating the lake into a north and south arm. Flow between the two arms was limited to two 4.6...

Sediments from 28 saline and hypersaline (salinity 13.6–149.2) ponds on Christmas Island (Kiritimati), in the Central tropical Pacific Ocean, were investigated for the effect of salinity on the D/H ratios of lipid biomarkers. Hydrogen isotope ratios (expressed as dD values) of total lipid extracts, and individual hydrocarbons heptadecane, heptadecene, octadecane, octadecene, diploptene, and phy...

Rice seedlings cv. Khao Dawk Mali 105 (salt-sensitive), Luang Anan (moderately salt-tolerant) and Pokkali (salt-tolerant) were exposed to 0, 50, 100 and 150 mM NaCI for 9 d. Salinity stress caused reduction in leaf relative water contents in all cultivars. Shoot length of cv. Pokkali was least affected by salinity stress whereas increased root length in response to salinity stress was apparent ...

Responses to moderate and extreme salinity change were investigated in White Sea Littorina saxatilis of different genetically determined shell colour morphs in order to test a hypothesis about physiological selection as a driving force of the change of phenotypic structure of this species along a salinity gradient in White Sea estuaries. Some of the studied physiological responses did not diffe...

To understand the effects of predicted warming and changing salinity of marine ecosystems, it is important to have a good knowledge of species vulnerability and their capacity to adapt to environmental changes. In spring and autumn of 2014, we conducted common garden experiments to investigate how different populations of the copepod Eurytemora affinis from the Baltic Sea respond to varying tem...

Salinity stress hampers plant growth and cause significant yield losses thus induction of salinity stress tolerance in crop plants is one of major goals of agriculture research. Arbuscular mycorhizae fungi Glomus etunicatum and acetyl salicylic acid were tested for induction of NaCl stress tolerance in tomato seedlings, cultivar No. 4. The seedlings were inoculated with Glomus etunicatum and ex...

Electromagnetic induction (EM) is a useful mean of assessing soil salinity in large areas, particularly after its calibration on different soils. Electromagnetic induction was used to monitor spatial and temporal changes of soil salinity within the saline irrigation district of Flumen, Spain. Soil salinity patterns in this region are entangled because of intensive land leveling and irrigation. ...

A key issue for agriculture in irrigated arid lands is the control of soil salinity, and this is one of the goals for irrigated districts when changing from flood to sprinkling irrigation. We combined soil sampling, proximal electromagnetic induction, and satellite data to appraise how soil salinity and its distribution along a previously flood-irrigated field evolved after its transformation t...

The ability to identify past patterns of salinity habitat use in coastal fishes is viewed as a critical development in evaluating nursery habitats and their role in population dynamics. The utility of otolith tracers (δ13C, δ18O, and Sr/Ca) as proxies for environmental salinity was tested for the estuarine-dependent juvenile white perch Morone americana. Analysis of water samples revealed a pos...

Soil salinity seriously limits plant growth and yield. Strategies have been developed for plants to cope with various environmental stresses during evolution. To screen for the broad-spectrum genes and the molecular mechanism about a hydroxyproline-tolerant mutant of peanut with enhanced salinity resistance under salinity stress, digital gene expression (DGE) sequencing was performed in the lea...
