RCP2.6 represents low emissions scenario and RCP8.5 represents high emissions scenario.

(a) baseline climate 1960–1990, (b) low emissions scenario (RCP2.6) 2041–2060, (c) low emissions scenario (RCP2.6) 2061–2080, (d) high emissions scenario (RCP8.5) 2041–2060 and (e) high emissions scenario (RCP8.5) 2061–2080.

Mean distribution density of An. gambiae species in each Nigerian state under baseline climates 1960–1990 and low emissions scenario (RCP2.6) / high emissions scenario (RCP8.5) in 2041–2060 (2050s) and 2061–2080 (2070s).
Note: red boundary line on the graph defines presence and absence conditions for each Anopheles species from zonal statistics; if 1 ≡ 0 (species does not occur), >1 = species occur, and 2 = maximum species prevalence [38].
