Natural variation in desiccation survival across European natural D. melanogaster populations. A Geographical origin of the nine populations analyzed in this study. The location of the populations is indicated with arrows in a map of Europe colored based on the Köppen-Geiger climate zones, except for Tenerife, which is not shown in the map (Additional file 1. Table S1). B Desiccation survival of European natural populations. LT100 values for the 59 inbred strains (three replicates/strain) that showed less than 10% control mortality are shown (Additional file 3. Table S2A). The Y-axis represents the average hour when the flies in all the replicates were dead, and the X-axis represents the individual strains colored by the climate zone in which they were collected. Data are presented as mean values ± SD. C Boxplot of the distribution of the LT100 values of the strains, grouped by climate zones (Additional file 3. Table S2A). The boxplot shows the median (the horizontal line in the box), 1st and 3rd quartiles (lower and upper bounds of box, respectively), and minimum and maximum (lower and upper whiskers, respectively)
