Field course in stable isotope methods in ecology with University of Bayreuth

We just got back from the Hakalau Forest National Wildlife Refuge on Hawaii Island where Nicole, Chris and Sean were leading a field course in stable isotopes in ecology with students from the University of Bayreuth Germany taught by Prof. Gerhard Gebauer. Using carbon and nitrogen stable isotope analysis we’ll be examining how nitrogen fixation by the native tree Acacia koa differs between remnant and restored forest habitats.
