This study uses radiocarbon dating of eye lenses in birds and mammals to reconstruct long-term chronological information, finding that mammalian lenses span years of life while avian lenses cover several years to decades.

This study introduces a method to reconstruct brown bear dietary history using eye lens isotopes, showing age-related dietary shifts and corn consumption patterns.

This study uses isotope analysis of bird eye lenses to reconstruct early-life dietary and environmental history, showing that lens isotopes reflect prenatal and postnatal diet changes.
