background and objectives: phytoplanktons are organisms with a very high diversities and global distribution in different habitats. the high distribution of phytoplankton is due to ecological flexibility and their ability to tolerate different climatic conditions and environmental stress. phytoplankton is the most sensitive biological indicators of water resources. the purpose of this study was...

[1] Magnitudes of terrestrial (fresh) and marine (saline) sources of submarine groundwater discharge (SGD) are estimated for a transect across Indian River Lagoon, Florida. Two independent techniques (seepage meters and pore water Cl concentrations) show terrestrial SGD decreases linearly to around 22 m offshore, and these techniques, together with a model based on the width of the outflow face...

BACKGROUND AND OBJECTIVES: The eutrophication process is increased by anthropogenic or aquaculture facilities in marine ecosystems. DNA damage biomarkers for fish species detect genotoxic parameters for ecological risk assessment. The aim of the present study was to determine genotoxic potential induced by marine cage culture in Iskenderun Bay on gilthead sea bream (Sparus ...

Marine environmental monitoring based on wireless sensor networks (WSN) is a challenging area of research due to the instability of the water field. Due to the characteristics of the water environment, there are certain considerations which must be taken into account before the establishment of marine based wireless sensor networks. These include the deployment of wireless nodes (WNs), energy c...

Biotyping and DNA fingerprinting by pulsed-field gel electrophoresis were applied to a collection of enterococci recovered from recreational and drinking water, in order to identify possible genetic relationships. Clinical strains of hospital origin were compared to the environmental isolates. A total of 104 enterococci were isolated from 128 recreational water (94 marine and 34 river water) an...

the qom formation in naragh area, with 185 meter thickness, is exposed about 25 km northeast of delijan. this formation in the studied area, lithologically, consists of shale, gravely limestone, and sandy limestone, with thin, medium to thick bedded and massive limestons. it disconformably covers the lower red formation and is covered by recent alluvium. in this research, the role of large fora...

Nowadays seas and oceans are exposed to serious threats such as land-based sources of marine pollution, the overexploitation of living marine resources, the physical alteration or destruction of the marine habitat and the horizontal transfer of marine species to new environments in ballast water. When marine species are introduced into new environments and the living conditions there are favora...

Structural concrete exposed to marine environment deserves special attention as the diffused sea salts chemically react with harden cement matrix and forms various expansive/leachable compounds leading to loss of material, strength, cracking, spalling etc. This study cover the effect of sea water on the specimens cast from two grades of concrete exposed to simulated marine environment over a ye...

in the homeostatic control of body fluid and ionic balance. In terrestrial mammals, a 1–2 % deficit in cellular fluid volume is sufficient to induce a powerful drinking response, whereas 8–10 % of extracellular fluid loss is required to induce dipsogenesis (Fitzsimons, 1998). As a consequence, an increase in plasma osmolality, or hyperosmoraemia, acts as a more acute trigger for drinking in mam...
