Trophic Relationships and Habitat Preferences of Delphinids from the Southeastern Brazilian Coast Determined by Carbon and Nitrogen Stable Isotope Composition

Abstract W e tested the impacts of most common sample preservation methods used for aquatic sample materials on the stable isotope ratios of carbon and nitrogen

Fifty percent of labile organic carbon is exported by the biological pump and 50% by subduction; 98% of the total carbon flux below the mixed layer is due to carbon

The observation of the Earth by satellite is a source of information on the ocean and the atmosphere thanks to the measures of radiances. As it was said above this data can be

Significance of spatial and temporal variations of stable isotope values (δ 13 C and δ 15 N) of coral host tissues and stable isotope differences between coral host tissues and

(1) upstream of the Rio Negro and the Rio Solimo˜es confluence, almost no seasonal variation was observed around the regional average of –29.2  0.6%; (2) upstream of Itacoatiara

Indeed, osmotic pressure has an important positive effect on the rate of the reaction and from the slope of the variation of the rate constant as a function of
