This paper develops a method to infer bird migration from bone isotopes and histology, showing a correlation between δ18Op and migratory behavior in extant birds, with potential applications to fossils.

This paper reassesses body temperatures and thermoregulation strategies of Mesozoic marine reptiles using oxygen isotope data, finding ichthyosaurs were homeothermic endotherms, plesiosaurs likely poikilothermic endotherms, and metriorhynchids poikilothermic with limited endothermy.

This study analyzes nitrogen isotope values in Predynastic Egyptian mummies and surrounding materials to suggest localized soil fertilization practices in extreme conditions.
