Based on Scanning Proton Microprobe Analysis of Otolith Strontium Distribution
ABSTRACT. Scanning proton microprobe analysis was used to determine the distribution of strontium (Sr) in otoliths from arctic charr (Salvelinus alpinus) of known non-anadromous, known anadromous, and unknown life histories. Strontium concentration patterns in otoliths of known non-anadromous charr...
