Abstract

Dalmatinski buhač (Tanacetum cinerariifolium /Trevir./Sch.Bip.) endemska je biljna vrsta istočnog Jadrana iz porodice Asteraceae koja sintetizira prirodni insekticid i repelent piretrin. Cilj rada bio je utvrditi najprikladnija staništa za dalmatinski buhač na području Hrvatske te odrediti potencijalne lokalitete za budući uzgoj izradom modela ekološke niše. Za modeliranje su korištene geografske koordinate lokacija na kojima je vrsta zabilježena i bioklimatske varijable za područje Jadrana. Najveća prikladnost staništa na području Hrvatske utvrđena je na priobalnim područjima i otocima Dalmacije i Hrvatskog Primorja. Prosječna vrijednost AUC (area under the curve) za 100 ponavljanja modela iznosila je 0.980 uz standardnu devijaciju od 0.004 ukazujući na visoku prediktivnu snagu modela. U svrhu dodatne procjene kvalitete dobivenog modela on je projiciran na područje Tasmanije kao jednog od većih komercijalnih proizvođača buhača. Prema modelu prikladna su samo sjeverna i sjeverozapadna obalna područja Tasmanije sa prikladnošću staništa većom od 50 %. Analiza prikladnosti staništa po hrvatskim županijama pokazala je da je najprikladnija županija za uzgoj buhača dubrovačko-neretvanska.

Abstract (english)

Dalmatian pyrethrum (Tanacetum cinerariifolium /Trevir./Sch.Bip.) is an endemic plant species of the eastern Adriatic from the family Asteraceae, which synthesizes natural insecticide and repellent pyrethrin. The aim of this thesis was to determine the most suitable habitats for Dalmatian pyrethrum on the territory of Croatia and to determine potential locations for future cultivation by. Suitable habitats were determined by constructing an ecological niche model using geographical coordinates of recorded locations for species and bioclimate variables for Adriatic area. The greatest habitat suitability on the territory of Croatia was determined on the coastal areas and islands of Dalmatia and in the region of Hrvatsko Primorje. The average AUC score (area under the curve) for 100 replicates of the model was 0.980 with standard deviation of 0.004 which indicates a highly predictive model. To further assess the quality of the obtained habitat suitability model, it was projected on the territory of Tasmania which represents one of the largest commercial producers of pyrethrum. According to the model, only the northern coastal areas of Tasmania are suitable with habitat suitability higher than 50 %. The analysis of habitat suitability of Croatian counties revealed that the most suitable county for pyrethrum cultivation is Dubrovnik-Neretva County.
