A field‐derived oxygen isotope fractionation equation for Salvelinus species
Abstract Field‐collected otolith samples of young‐of the‐year Arctic charr ( Salvelinus alpinus ) and brook charr ( Salvelinus fontinalis ) and monitored water temperatures were used to estimate a δ 18 O fractionation equation for the genus Salvelinus . When compared to literature reported equations...
