C13 and N15 isotope values of selected invertebrates and plants

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

Stable Isotopes were used to eludicate shifts in arthopod food webs in Bioenergy crop landscapes.

This datatable is part of the Ant Isotope ratios dataset. This is data supporting the publication: Jackson A. Helms IV et.al 2020. “Bioenergy landscapes drive trophic shifts in generalist ants” in the Journal of Animal Ecology.

These data document tissue stable isotope ratios of C and N in plants and invertebrates collected by hand or in pitfall traps during the 2018 growing season from the Biofuel Cropping System Experiment (BCSE) plots and the GLBRC Scale-Up Experiment.
