In 2005, a new lizard species, the sharp-snouted rock (Dalmatolacerta oxycephala) appeared on island of Cres, probably due to anthropogenic transfer. Before that, only Dalmatian wall (Podarcis melisellensis) had inhabited town Osor, where species was discovered. areas two live sympatrically, P. melisellensis is competitively superior D. oxycephala; however, in oxycephala parts been present before. Since there has no systematic survey assess how distribution changed Osor and, aim this study investigate far spread and what happened native after appeared. Here we show that 16 years, outcompeted by lizard, observation together at same locations. Despite preferring high stone walls, specimens were also found shorter walls alongside road towards Lošinj. According our findings, further cannot be excluded upcoming years which could negatively affect but research needed reveal causes observations monitor changes species.
