An Experimental Evolution Test of the Relationship between Melanism and Desiccation Survival in Insects
Fig 3
Pigmentation status (as gray scale score) in D and F populations after ~140 generations of laboratory natural selection.
Upper panel, females; lower panel, males. Open bars, fed (F) controls; filled bars, desiccation-selected (D) populations. Data are means (±s.e.). For each sex, n = 15–20 per replicate population.
