| Abstract |
Stable carbon and nitrogen isotope ratios have been determined on 41 strains of Artemia sp. from different geographic regions around the world. The delta 13C and delta 15N values ranged between -13.7 to -25.0 per mil and -0.7 to 21.2 per mil respectively. Artemia delta 13C values from coastal environments are consistent with a marine origin for the food source. Artemia from inland salt lakes have a range of carbon isotope values suggesting C3, C4 and CAM based organic matter could form the base of the Artemia food chain. These data indicate that Artemia having a wide range of carbon and nitrogen isotope values are available for trophodynamic research studies that quantify the effect of respired CO2 on tissue and CaCO3 shell 13C/12C ratios. Such stable isotope variation also suggests that stable isotope fingerprinting remains a viable technique for identifying specific Artemia collection sites. |
