Age determination of minke whales (Balaenoptera acutorostrata) using the aspartic acid racemization technique
@article{Olsen2002AgeDO, title={Age determination of minke whales (Balaenoptera acutorostrata) using the aspartic acid racemization technique}, author={Erik Olsen and Jan Sunde}, journal={Sarsia}, year={2002}, volume={87}, pages={1 - 8} }
Eyeballs were collected from 31 female minke whales caught in the North Sea, Norwegian Sea and Barents Sea. The eye-lens nucleus was dissected out and the relative amount of D- and L- enantiomers of aspartic acid measured using high-performance liquid chromatography (HPLC). A racemization reaction changes the D/L aspartic acid relationship in the nucleus over time. The age of each whale was estimated using the racemization rate for fin whales along with the measured D/L ratio. The minimum age…
