The secrets of a sea lion’s diet may lie in the chemical composition of its blubber. Scientists hope that analyzing the fatty acids in blubber using a new technique called Quantitative Fatty Acid Signature Analysis (QFASA) will help them describe long-term dietary trends. But is QFASA a reliable means to determine the diets of seals and sea lions? A new Consortium paper looks into this promising approach. April 22, 2013.
