Abstract:

This dataset lists the bulk stable isotope values (delta-13C, delta-15N, and delta-34S) for tissue samples collected in 2015 for the food web project within the Coastal Waters Consortium II. It includes tissue samples of multiple consumers (fish, invertebrates, terrestrial vertebrates) as well as primary producers from salt marshes in southern Louisiana. Information gathered at the time of collection for each sample in this dataset can be found in the 2015 Food Web Sample Key (GRIIDC R4.x264.218:0001) by referencing the CWC ID Number. Additional dataset authors are Olaf Jensen, Ken Able, Joel Fodrie, Michael Polito, Jill Olin, Jessica Johnson.

Purpose:

This dataset summarizes the bulk stable isotope values (delta-13C, delta-15N, and delta-34S) of multiple consumers and producers in southern Louisiana salt marshes. For each sample, the delta-13C and delta-34S values are indicators of energy sources, and delta-15N values indicate trophic position. Therefore, these data can be used to understand the food web structure in these salt marshes.

Data Parameters and Units:

CWC ID Number: code assigned by our group to every sample collected Laboratory: where samples were analyzed delta-13C: stable carbon isotope values in ‰ %C: percent carbon delta-15N: stable nitrogen isotope values in ‰ %N: percent nitrogen C:N: the %C value divided by %N delta-34S: stable sulfur isotope values in ‰ %S: percent sulfur
