As promised, I'm only going to assign two papers for discussion next week. They both continue our discussion of stable isotopes from November 17. The first describes spatial patterns of delta 180 in precipitation and shows how latitude, altitude and moisture transport patterns create a 'global fingerprint' in water chemistry. The second paper uses stable isotope records from trees without rings to argue that El Nino was the true culprit responsible for the demise of the Monteverde golden toad.
