The vegetation is typically Mediterranean, dominated by pines (Pinus pinea) and ilexes (Quercus ilex). As expected, the most abundant species was D. subobscura, because it presents a peak of expansion in autumn . D.simulans was at a fairly high frequency, due to its autumnal expansion period in Mediterranean populations. The invasive species D. suzukii was also found, and it seems that it has established a rather stable way in this place1 p.application/pdfeng(c) Rojo, E. et al., 2019DrosòfilaCollserola (Catalunya : Serra)DrosophilaCollserola Mountains (Catalonia)info:eu-repo/semantics/article6949052020-02-03info:eu-repo/semantics/openAccess
