Figure 5

Distribution in multivariate ordination space of chromosome-2 karyotypes of the An. gambiae molecular forms. Detrended Correspondence Analysis (DCA) of chromosome-2 karyotypes in the M (blue circles) and S (green squares) molecular forms of An. gambiae on the first two ordination axes. Karyotypes are encoded according to the sequence of inversions on chromosome-2, each digit corresponding to the observed karyotype for inversions 2Rj,b,c,d,u,k and 2La, respectively. Eco-geographical variables (EGVs, see Methods) are passively plotted (unconstrained analysis) in the upper-right diagram to show how they correlate with the two ordination axes. For visualization clarity, only EGVs with significant scores are shown. The lower-right diagram zooms in to show the crowded central part of the main diagram on the left. All three diagrams are intended to be part of the same plot, and are here separated only for visualization purposes. WVP: Water Vapour Pressure; sun-expo: Sunlight exposure; dist-road: Distance to roads; dist-water: Distance to water bodies; Deciduous: Deciduous woodland; Mosaic: Forest-savanna mosaic.
