Figure 2From: Living at the edge: biogeographic patterns of habitat segregation conform to speciation by niche expansion in Anopheles gambiaeInterpolated relative abundance of members of the Anopheles gambiae complex in Burkina Faso. Maps of the kriged relative frequency of members of the Anopheles gambiae complex across Burkina Faso: A) An. arabiensis (vs. An. gambiae); B) An. gambiae molecular form S (vs. form M). The figure also shows major populated places (>10,000 inhabitants; labelled dots), and sampled locations used as interpolators (stars). Continuous lines denote mean annual rainfall isohyets for the period 1970–2000.Back to article page
