Population divergence in male mate preferences of Calopteryx splendens (Figure 3B)

Data for C. splendens male population divergence in mate preferences in sympatric (S) and allopatric (A) populations, as shown in Fig. 3B (Svensson et al. 2014). Male mate preferences have been normalized by dividing by the average male response to conspecific C. splendens females (indicated by line at ‘1’ in Fig. 3B). For statistical tests, see legend to Fig. 3B in Svensson et al. (2014).
