Fish stable isotope dataset.
Description
A dataset containing values for three stable isotopes measured in the muscle tissue of four species of arctic fish. For use in examples.
Usage
fish
Format
A data frame with 278 rows (observations) and 4 columns (species, \delta^{15}N, \delta^{13}C, and \delta^{34}S).
Details
This dataset contains \delta^{15}N, \delta^{13}C, and delta^{34}S values for the following fish species:
ARCS - Arctic Cisco (Coregonus autumnalis), n = 69.
BDWF - Broad Whitefish (Coregonus nasus), n = 71.
LKWF - Lake Whitefish (Coregonus clupeaformis), n = 67.
LSCS - Least Cisco (Coregonus sardinella), n = 70
Source
Fish were collected between 2007 and 2008 from an estuarine area of the Beaufort Sea, North and West of the Mackenzie Delta at Phillips Bay, Yukon Territory, Canada (69.28 N, 138.49 W).
