Abstract:

This dataset lists the bulk stable isotope values (delta-13C and delta-15N) for invertebrate species tissue samples collected in 2014 as a component of the Seaside Sparrow project within the Coastal Waters Consortium. These samples were analyzed at the University of Windsor (Windsor, ON, Canada). Information gathered at the time of collection for each sample in this dataset can be found in the 2014 Invertebrate Sample Key (GRIIDC dataset R4.x264.000:0068) by referencing the DATABASE ID.

Purpose:

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

Methods:

The standards used to correct for bulk stable isotopes were NIST bovine liver (NIST 1577C) and an internal fish standard
