A set of trophic discrimination factors for brent geese feeding on their sources.

Description

A dataset of estimated trophic discrimination factors for brent geese. The data assume the same TDF for each food source. Intended for use in a Stable Isotope Mixing Model.

Usage

data(correctionsdemo)

Format

A 5 column, 4 row data.frame object containing the trophic discrimination factors for brent geese consumers relative to 4 of their food sources (in Ireland). The first column Source is a factor determining the name of the source. The second and third columns are the mean d13C and mean d15N TDF values for each source respectively. Columns 3 and 5 are the standard deviations of the d13C and d15N TDF values respectively. Note that the order of the isotope data has been swapped since siar in order to present d13C as the first isotope and hence on the x-axis by default.
