DNA obtained from invertebrates (iDNA) can be metabarcoded in order to survey vertebrate communities. Here, we tested for specialization by sampling the dung and carrion fly community of a swamp forest remnant along a disturbance gradient (10 sites: 80–310 m from a road). This dataset contains Illumina and MinION datasets corresponding to metabarcoding experiments on 435 fly faecal samples. This involved the amplification of 3 genes (COI 244-bp fragment, COI 313-bp fragment, and 16S) from...
