Dear Marmamers, We are pleased to announce the recent publication of our paper in Rapid Communications in Mass Spectrometry. Our approach will be useful to anyone considering stable isotope analysis of skin and blubber biopsies of fin, humpback and minke whales (or indeed other cetacean species) Click here<http://onlinelibrary.wiley.com/doi/10.1002/rcm.6394/abstract;jsessionid=E50C23B3991017ED21DCC0E3E9AF4186.d01t01?deniedAccessCustomisedMessage=&userIsAuthenticated=true>for link. Ryan, C., McHugh, B., Trueman, C. N., Harrod, C., Berrow, S. D., & O'Connor, I. (2012). Accounting for the effects of lipids in stable isotope (δ13C and δ15N values) analysis of skin and blubber of balaenopterid whales. *Rapid Communications in Mass Spectrometry*, *26*(23), 2745-2754. I will be happy to provide pdf copies upon request. -- Dr Conor Ryan Marine Biodiversity Research Group, Marine & Freshwater Research Centre, Galway-Mayo Institute of Technology, Dublin Road, Galway, Ireland ________________________________ Cape Verde Humpback Whale Research Blog http://cvihumpbacks.blogspot.com/
