Two-dimensional ordinations (plots A and B) of the 3-dimensional correspondence analysis showing the collected Anopheles species (i.e. raw categories, blue) and the village-collection sites (i.e. column categories, red). The dimensions in the ordination plot show the metric distances. The smaller the distances between points, the "stronger" their associate i.e. points of a certain category positioned close to each other are similar with regard to the pattern of relative frequencies across the other category. Village-collection sites; Phuoc-village: village in Phuoc Binh, Phuoc-forest: forest in Phuoc Binh, Manoi-village: village in Ma Noi, Manoi-forest: forest in Ma Noi.
