Fig. 3From: Species abundance, composition, and nocturnal activity of female Anopheles (Diptera: Culicidae) in malaria-endemic villages of Papua New Guinea: assessment with barrier screen samplingPCoA biplot based on Bray–Curtis index matrix of five villages (black) with projected weighted average scores of six Anopheles species (blue). The importance of the two orthogonal axes labelled PC1 and PC2 was determined by their eigenvalues and the percentage represents the proportion of variation explained by each axis. The species An. hinesorum was excluded from the analysis due to very low sample sizeBack to article page
