| from puffins to plankton: a dna-based analysis of a seabird food chain in the northern gulf of maine. | the predator-prey interactions within food chains are used to both characterize and understand ecosystems. conventional methods of constructing food chains from visual identification of prey in predator diet can suffer from poor taxonomic resolution, misidentification, and bias against small or completely digestible prey. next-generation sequencing (ngs) technology has become a powerful tool for diet reconstruction through barcoding of dna in stomach content or fecal samples. here we use multi-l ... | 2013 | 24358258 |
