Influence of animal proxy choice on use of carbon, nitrogen and oxygen stable isotope ratios for determining past environmental variables (2017)

DOCUMENT Citation Only Margaret Schoeninger. Corinna Most. James Moore. Andrew Somerville.

The stable isotope ratios of carbon, nitrogen and oxygen (δ13C, δ15N, and δ18O values) in animal tissues show promise as environmental indicators. We evaluated the use of chimpanzee hair and leporid (jackrabbit and cottontail) bones. Chimpanzee hair δ13C values correlate negatively with mean annual precipitation (MAP) as expected based on isotope variation in C3 plants, whereas δ15N values do not because of diet selectivity. Leporid bone δ13C values do not correlate with MAP because of leporid...
