Description

Raw data for: Feiner, Z.S., C.J. Foley, H. Bootsma, S. Czesny, J. Janssen, J. Rinchard, and T.O. Hook. Species identity matters when interpreting trophic markers in aquatic food webs. Manuscript submitted to PLOS ONE.

Description: Diet content, stable isotope, and fatty acid data taken from 3 fish species (yellow perch Perca flavescens, spottail shiner Notropis hudsonius, and round goby Neogobius melanostomus) sampled around Lake Michigan in 2010. Diet content and fatty acid data are expressed as proportions of total diet by biomass and proportional abundance of all fatty acids measured, respectively. Stable isotope data are expressed in ratios per mille (‰). Three datasets, using each pairwise combination of trophic markers, were used in the analysis (each tab). Definitions for column names found in "Metadata" tab.
