In this paper, it is shown that coherent large-scale low-frequency variabilities in the North Atlantic Ocean—that is, the variations of thermohaline circulation, deep western boundary current, northern recirculation gyre, and Gulf Stream path—are associated with high-latitude oceanic Great Salinity Anomaly events. In particular, a dipolar sea surface temperature anomaly (warming off the U.S. ea...

the development of seminal and lateral root system plays a major role in plant access to water and nutrients under abiotic stress, especially salinity. in order to understand the relation between root growth responsesand shoot physiological indices oftwo bread wheat cultivars contrasting in salt tolerance (kavir and shiraz), a greenhouse experiment was conducted with two salinity levels (0 and ...

in order to the study of the salinity effects on seed germination and effecting parameter of fennel (foeniculum vulgare) was conducted a factorial experiment in a completely randomized design with two factors and three replications. factor a was 10 ecotypes, including; sardasht, saghghez, kerman, tabriz,sabzevar, rome, khusf, bojnoord, mashhad and shabestar and factor b was five concentrations ...

the genus thymus is perennial medicinal plants belong to the lamiaceae familythat is used for different propose in pharmaceutical industry. environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. the purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

Acclimated and acute rates of oxygen consumption of the American oyster Crassostrea virginica (Gmelin) were measured under 9 salinity-temperature combinations during declining oxygen tensions. In acclimated and non-acclimated individuals the basal rate of oxygen uptake increased significantly with each 10 C" rise in temperature. Multiple regression equations relating exposure and experimental t...

to investigate the effect of dietary supplementation of l-carnitine on resistance to temperature and salinity stresses in sobaity fry, an experiment was carried out with 240 pieces of fish with average initial weight of 3.01±0.03 g for 10 weeks. experimental treatments were consisted of four levels of 0, 500, 1000 and 1800 (respectively control, lc500, lc1000 and lc1800) mg l-carnitine per kg o...

Late embryogenesis abundant proteins (LEA) are stress resistance-related proteins that play crucial roles in protecting against desiccation, cold and high salinity in a variety of animals and plants. However, the expression pattern, distribution and functions of LEA proteins in the post-diapause period of Artemia sinica, and under high salinity and low temperature stresses, remain unknown. In t...
