Model output and K-fold cross validation output is also included as .rds files. Code for generating figures is contained within the model .rmd file.This data set contains fresh and ethanol fixed zooplankton samples collected from five Minnesota lakes during June 2022. The data were collected with five paired sites at each lake. The samples were filtered to remove detritus, phytoplankton, and predatory invertebrates. After filtering, each sample was split between fresh processing and ethanol storage. Ethanol storage samples remained in storage for approximately one month. Samples were sent to the UC-Davis Stable Isotope Facility for analysis. Stable isotope values in addition to lake name, DOW, and site of collection are included in the data file. Bayesian Hierarchical models were used to establish correction factors for ethanol storage. Statistical analysis was performed using the R package brms and model output can be found in respective .rds files. Details for each file can be found in the readme file.CC0 1.0 Universalhttp://creativecommons.org/publicdomain/zero/1.0/zooplanktonethanol storageisotope correctionDatasethttps://doi.org/10.13020/kw5w-1584
