In the present study, the heavy metal concentration in different organs (skin, tissue, liver, kidney, gill, intestine, and ovary) and muscle proximate composition were studied in marine edible puffer fishes Takifugu oblongus, Lagocephalus guentheri, Arothron hispidus, Chelonodon patoca and Arothron immaculatus collected from Mandapam fish landing centre, South east coast of India. Heavy metals ...

Endothelial nitric oxide synthase (eNOS or NOS3) is the main responsible for nitric oxide (NO) production in vascular system and different polymorphisms have been identified in epidemiological studies. Trying to test the eNOS genetic variation in general populations we studied the 27-bp VNTR in intron 4 and G894T substitution in exon 7 markers in 6 Western Mediterranean populations (3 from Iber...

New three-dimensional (3-D) Vp and Vp/Vs models are determined for southern California using P and S-P travel times from local earthquakes and controlled sources. These models confirm existing tectonic interpretations and provide new insights into the configuration of geological structures at the Pacific-North America plate boundary. The models extend from the U.S.-Mexico border in the south to...

the fouling barnacle amphibalanus improvisus is a cosmopolitan biomonitor of trace metal bioavailability in coastal waters of reduced salinity such as estuaries or the baltic sea. bioavailability of ag, as, cd, co, cr, cu, fe, mn, ni, pb, v and zn to a. improvisus was investigated in july 2014 at 15 sites along the iranian coast of the understudied, yet biologically unique, caspian sea. in gene...

Although pairs of species often interact over broad geographic ranges, few studies have explored how interactions vary across these large spatial scales. Surveys along 1500 kilometers of the Pacific coast of North America documented marked variation in the frequency of predation by the snail Nucella canaliculata on the intertidal mussel Mytilus californianus. Laboratory rearing experiments sugg...

Seasonal variations of physico-chemical parameters such as rainfall, temperature, salinity, pH, dissolved oxygen and nutrients like nitrate, nitrite, inorganic phosphate and reactive silicate were studied from two different stations in Uppanar estuary, Cuddalore, southeast coast of India from April 2000 to March 2002. Atmospheric and surface water temperatures (°C) varied from 28 to 40.5 and 26...

The spreading and movement of oil slicks is strongly influenced by surface water movement. On the Gest coast, surface water movement is affected by weather systems and storms from the north Pacific, which have a high incidence of gale force winds and high seastates. It is also affected by large tidal ranges. strong tidal currents and irregular coastlines. Air and water temperatures, water salin...

The Lake Warden wetland system (LWWS), on the south coast of Western Australia (WA), is a wetland of international importance for waterbirds. It occurs at the bottom of a heavily cleared agricultural catchment. Rising water levels associated with clearing have been identified as a threat to waterbird diversity. Different species of waterbird are typically found in specific ranges of water depth...

Surface exposure ages of glacial deposits in the Ford Ranges of western Marie Byrd Land indicate continuous thinning of the West Antarctic Ice Sheet by more than 700 meters near the coast throughout the past 10,000 years. Deglaciation lagged the disappearance of ice sheets in the Northern Hemisphere by thousands of years and may still be under way. These results provide further evidence that pa...
