Isotope shifts during processing and freezing

Data in the KBS LTER core database may not be published without written permission of the lead investigator or project director Full terms of use

To evaluate the effect of ethanol preservation and freezing on stable isotope values, Ants were collected from a gravel road near the site and preserved with ethanol or freezing as described in Jackson et.al. 2020. Bioenergy landscapes drive trophic shifts in generalist ants. Journal of Animal Ecology.

Ants were collected on 2018-09-12.

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.
