“…This includes scenarios that: (i) placed a specific amount of uncertainty on one location while uniformly distributing the remaining amount across all other candidate locations (correspondingly labeled 10, 30, and 50); (ii) assigned the remaining uncertainty to just one other location; thus ‘splitting’ the uncertainty among two locations (i.e. 10/90, 30/70, and 50/50); and (iii) eliminated uncertainty via two predefined heuristic approaches: assignment to a centroid location (CNTR) or the largest population in the country (POP). We compared all scenarios to a reference standard (RS) in which all taxa had known (absolutely certain) locations. …”

“…METHODS: Insect samples, belonging to six orders (Orthoptera, Coleoptera, Lepidoptera, Hemiptera, Odonata, Hymenoptera) were purchased from five European and three Asian countries. POPs and halogenated FRs were analyzed by gas chromatography–mass spectrometry (GC/MS) and organophosphorus FRs and plasticizers were quantified by liquid chromatography–MS/MS, according to validated protocols. …”
