Eyes and ears: a comparative approach linking the chemical composition of cod otoliths and eye lenses.
Abstract Fish eye lenses are a protein-based chronological recorder of microchemical constituents that is a potentially useful tool for interpretations of environmental, ecological, and life-history experienced by fish. Here, we present the first study with data of the chemical composition of eye le...
