In their previous papers, the authors of this study have suggested and realized a method of simultaneous determination of temperature and salinity of seawater using laser Raman spectroscopy, with the help of neural networks. Later, the method has been improved for determination of temperature and salinity of natural water using Raman spectra, in presence of fluorescence of dissolved organic mat...

The effects of environmental factors and exudates from the amphipod Corophium volutator on the emergence of Maritrema subdolum cercariae (Digenea: Microphallidae) from the snail Hydrobia ulvae were investigated in the laboratory. Increasing the temperature (15 to 25 degrees C) caused an overall 11-fold increase in emergence rate under varying salinities (24 to 36 per thousand). The effect of sa...

The various life stages of the Dungeness crab, Cancer magister, may experience broad environmental fluctuations in both salinity and temperature, parameters that can affect nearly all aspects of their physiological function. The routine rates of oxygen uptake of megalopa, first and fifth instar juvenile and adult C. magister were measured, using closed vessel respirometry over 8 h during acute ...

Crassostrea gigas D-shaped larvae were subjected to different conditions of temperature and salinity for 24 h and four biomarkers (acetylcholinesterase (AChE) activity, thiobarbituric acid reactive substances (TBARS) levels, glutathione S-transferase (GST) and catalase (CAT) activities) were measured. AChE activity decreased when salinity increased from 25 to 30 and 35 psu at 20 and 25 degrees ...

Seed heteromorphism observed in many halophytes is an adaptive phenomenon toward high salinity. However, the relationship between heteromorphic seed germination and germination-related hormones under salt stress remains elusive. To gain an insight into this relationship, the roles of gibberellins (GAs) and abscisic acid (ABA) in regulating germination of Suaeda salsa dimorphic brown and black s...

in the recent years, increasing production of waste as a result of population growth, increased food consumption, industrial development and urbanization growth, is regarded as a serious challenge. vermicompost, as an end product of urban waste recycling with proper physicochemical features, can play an effective role in plant growth and development and also in reducing harmful effects of vario...

in order to investigate the effect of mycorrhizal fungi and phosphorus fertilizer on concentration of leaf nutrients and photosynthetic pigments of bean (phaseolus vulgaris l.) in condition of irrigation with saline water, an experiment was conducted based on completely randomized design with three replications in greenhouse of bahonar university of kerman, iran during 2010. the studied factors...

This study reports effect of salinity on some growth attributes of two sugarcane cultivars at grand growth stage, in comparison with the control plants. In view of data presented here for different growth attributes, it is clear that responses of two varieties of sugarcane were different at different salinity levels. However, saline growth medium caused an overall reduction in growth in both th...

Hydrogen isotope ratios in lipids derived frommangroves have the potential to be used for paleohydrologic reconstructions and could serve as a much needed tool for establishing past climate variability in the tropics. We assessed the effect of salinity on the apparent fractionation factor, aa, between mangrove derived n-alkanes and their source water for Avicennia marina (gray mangrove) specime...

salinity is one of the environmental factors that have a critical influence on the germination of seeds and plant establishment. salinity affects imbibition, germination and root elongation. in this study, the germination characteristics of matricaria comomilla and thymus deanensis were studied. the purpose of this study was to investigate the effect of salinity on germination of these species....
