Analysis of Drosophila species distribution
The Diva-GIS 5.2 software (Hijmans et al. 2005) was used for plotting in maps the geographic coordinates where host species have already been
collected. The information about the species distribution was obtained in TaxoDros database (Bächli, 2008/12). This software not only positions the
coordinates but also makes a prediction of where else this species is probably able to inhabit. The figures S1 to S10 show the current and predicted
geographic distribution of Drosophila simulans, D. ananassae, D. yakuba, D. erecta, D. teissieri, D. malerkotliana, D. kikkawai, D. mojavensis, D. virilis,
Zaprionus indianus, respectively. The figure S11 shows the geographic distribution of all studied species displaying a large range of geographic overlapping.
The distribution of D. melanogaster, a known cosmopolitan species, was not included in the maps because the high number of collected points. For D.
mauritiana and D. sechellia, which are endemic from Mauritius and Seychelles Islands, respectively, no prediction of distribution could be conducted since
there is not available climate data for these geographic regions.
