Body size, trophic position, and the coupling of different energy pathways across a saltmarsh landscape

Here, we listed the bulk stable isotope values (δ13C and δ15N) and body
size measurements of organisms that were analyzed in the manuscript
"Body size, trophic position, and the coupling of different energy
pathways across a saltmarsh landscape", published in Limnology and
Oceanography Letters. Our dataset is a compilation of samplings obtained
by the Southern Louisiana marsh food webs project within the Coastal
Waters Consortium (CWC) II (Lopez-Duarte et al. 2017a
[https://doi.org/10.7266/N7XS5SGD], Lopez-Duarte et al. 2017b
[https://doi.org/10.7266/N79W0CJW], Polito et al. 2019
[https://doi.org/10.7266/n7-6277-1216]). The dataset consists of 1563
individual samples from 77 taxa, including basal sources (plants,
phytoplankton, detritus, and microphytobenthos), fishes, invertebrates
(insects, crustaceans, and spiders), infauna, seaside sparrows (Ammospiza
maritima), and marsh rice rats (Oryzomys palustris). Samplings were
conducted in three sites, Bay Sansbois, Bay Batiste, and West Pointe à la
Hache, located in northeastern Barataria Bay. Bay Sansbois and Bay Batiste
were sampled in May and October 2015, and May 2016, whereas West Pointe à
la Hache was sampled only in May 2016. Body size measurements are
available for 59% of all samples (52 taxa) while δ13C and δ15N are
available for all samples.
