A cost‐efficient and simple protocol to enrich prey DNA from extractions of predatory arthropods for large‐scale gut content analysis by Illumina sequencing

Summary Molecular analysis of predator gut content is a popular tool to uncover food web structure and has greatly profited from the emergence of next‐generation sequencing technology. However, the molecular recovery of prey spectra comes with many challenges, particularly the overabundance of predator DNA in extractions. When predator and prey are distantly related, predator‐specific blocking primers can be used to preferentially amplify prey...
