Figure 1

Geographic variation in locomotor activity among five American D. melanogaster populations. The graph was obtained from the Eduction analysis of FaasX software. The white bar underneath the graph represents the photophase, the black bar the scotophase. The populations are Maine (ME; latitude: 44°37′N), Rhode Island (RI; 41°49′N), Virginia (VA; 37°32′N), Florida (FL, 30°20′N) and Panama City (PC; 8°58′N). The raw locomotor activity profiles are shown on Additional file 1: Figure S2.
