Abstract (croatian)

Kranjski ljiljan (Lilium carniolicum Bernh. ex Koch) je trajna zeljasta biljka iz porodice ljiljana (Liliaceae). Raste na livadama i rubovima šuma i planinskih područja istočnih alpa: od Italije do Bosne. Zbog ljepote cvjetova (perigon) u Sloveniji je zakonom zaštićena već od 1947 godine. U Crvenoj knjizi vaskularne flore Republike Hrvatske vodi se u kategoriji osjetljivih (VU) biljaka te je zaštićena vrsta. Zbog velikog potencijala kranjskog ljiljana cilj je bio napraviti model potencijalnog rasprostranjenja s obzirom na ekološke čimbenike na području Hrvatske. Područje istraživanja su gorska i planinska područja Hrvatske, a model je napravljen metodom maksimalne entropije koja se pokazala pouzdanom u usporedbi s drugim metodama ekološkog modeliranja. Podaci o rasprostranjenosti kranjskog ljiljana preuzeti su iz baze podataka Flora Croatica (FCD), dok su klimatske podloge u obliku rasterskih slojeva preuzete iz WorldClim baze podataka koje su usklađene na istu rezoluciju, veličinu i WGS86 (World Geodetic System) koordinatni referentni sustav (CRS). Model je napravljen na temelju 12 klimatskih varijabli koje su prikazane u rasterskom obliku s vrijednostima piksela u rezoluciji 1x1 km. Svakoj točki prisutnosti vrste pridružena je vrijednost piksela svake klimatske varijable. Rezultati pokazuju da varijabla Bio18 (oborine najtoplijeg kvartala) ima statistički značajno najveći utjecaj na pogodnost staništa kranjskog ljiljana s 32,2%.

Abstract (english)

Carniolan lily (Lilium carniolicum Bernh. ex Koch) is a perennial herbaceous plant from the Liliaceae family, growing on the meadows and edges of forests and mountainous areas of the eastern alps: from Italy to Bosnia. Because of its beauty habitus and flowers it is often threatened and has been protected in Slovenia since 1947. In the Flora Croatica Red Book it is managed in the category of vunerable (VU) plants. Due to its great potential of Carniolan lily, the aim was to make a model of potential distribution with regard to ecological factors in Croatia. The field research was the mountain regions of Croatia and the model was done by the method of maximum entropy which proved to be reliable compared to other ecological modeling methods. The data of the distribution of Carniolan lily are taken from the Flora Croatica Database (FCD), while climatic layers in the form of raster are used from WorldClim databases, which are aligned to the same resolution, size and WGS86 (World Geodetic System) coordinate reference system (CRS). The model is based on 12 climate variables that are shown in raster form with pixel values at a resolution of 1x1 km. Each pixel point of the species is associated with the pixel value of each climatic variable. The results show that the variable Bio18 (percipitation of warmest quarter) has statistically significant influence on habitat suitability of Carniolan lily with 32.2%.
