Brevicoryne brassicae food web structure in native (UK) and invaded (NZ) ranges, and connectedness descriptors (see Bersier et al. 2002 and Thompson et al. 2012), based on the molecular study of aphid mummies (N=99). Full circles represent trophic levels identified to species level based on COI DNA sequences (>98% BLAST similarity) and full circles with disrupted borders represent MOTUs which could not be identified down to species based on the Genbank and BOLD databases.
