Data for: Hudson River juvenile Blueback herring avoid consuming microplastics

Each fish in this dataset was captured in the summer of 2016 in the Hudson River near Coxsackie, NY via beach seine.

PrelimFish: spec #, total length (mm), weight (g), species, and comments of all fish

FishDietData: zooplankton counts and microplastic counts within the gut of all fish, zooplankton counts and microplastic counts within the stream sample, zooplankton counts and microplastics counts within each lab control; microplastics are subdivided by both color and type

CompData: compilation of zooplankton/plastic counts and relevant PrelimFish data into one chart, removal of data points that had been compromised (dropped, spilled, mislabelled, etc), includes calculated totals per type and color

Cor&calc: CompData + calculations for the proportion of each diet/stream sample made up of each color/type of plastic, proportion of each diet/stream sample made up of zooplankton, proportion of each diet/stream sample made up of plastic as a whole, Jacob's Modified Electivity (JME) Index for each color/type of plastic in each gut, JME for zooplankton in each gut, repeats of final row of data for ease of computation; all diet samples were adjusted based on the lab control and the stream sample was adjusted based on the stream control

FishFinaltxt: Cor&calc data but only the columns needed for statistical analysis (totals, proportions, and JME's... no individual counts, excludes stream samples and controls)

UsedForStats: subset of the data that was used for statistical analysis (only includes the portion of the cor&calc data that was analyzed by the same individual who analyzed the stream sample, only includes blueback herring)

Rresults: summary of results obtained by analyzing UsedForStats in R
