Abstract

Ciljevi ove disertacije bili su doprinijeti boljem poznavanju faune trčaka naše zemlje s posebnim naglaskom na biologiju i ekologiju endemskih vrsta, kombinacijom morfoloških i molekularnih metoda doprinijeti razrješavanju taksonomskih odnosa između odabranih endemskih vrsta roda Carabus te otkriti eventualne promjene u sastavu zajednica trčaka na području Nacionalnoga parka Risnjak nakon 25 godina. U ovom istraživanju po prvi puta smo koristili mitohondrijske sekvence dviju endemskih vrsta Carabus (Platycarabus) creutzeri, Carabus (Eucarabus) parreyssi te vrste Carabus (Eucarabus) ulrichii u rekonstrukciji filogenetskog stablo roda Carabus. Kombinacijom linijske morfometrije, geometrijske morfometrije i molekularnih analiza pokušali smo utvrditi filogenetske odnose unutar dviju sestrinskih endemskih vrsta roda Carabus – C. croaticus i C. caelatus te utvrditi stvaran broj podvrsta i fenotipskih varijanti. Predložen je značajno manji broj podvrsta, a metode geometrijske morfometrije i u ovom su se primjeru pokazale korisnima za intraspecijsko razdvajanje vrsta nadilazeći probleme linijske morfometrije. Analiza sastava zajednica trčaka u razmaku od 25 godina ukazala je na smanjenje broja planinskih specijalista i širenje generalista unutar Nacionalnoga parka Risnjak. Izostanak endemskih vrsta Molops alpestris, Pterostichus unctulatus i Trechus croaticus u ulovu naglašava važnost daljnjeg kontinuiranog praćenja stanja zajednica kornjaša s ciljem poduzimanja ispravnih i pravovremenih konzervacijskih mjera.

Abstract (english)

Aims of this dissertation were to contribute to a better knowledge of the entomofauna of our
country with special emphasis on the biology and ecology of endemic species, a combination
of morphological and molecular methods to contribute to the resolution of taxonomic
relationships between selected endemic species of the genus Carabus and to recognise possible
changes in the composition of the carabids' assemblages in the Risnjak National Park after
period of 25 years. For the first time, in this study, we used the mitochondrial sequences of two
endemic species Carabus (Platycarabus) creutzeri, Carabus (Eucarabus) parreyssi and
another Eucarabus species Carabus ulrichii in the reconstruction of the Carabus phylogenetic
tree. Combining traditional morphometry, geometric morphometry and molecular analyses, we
attempted to determine the phylogenetic relationships within two sister endemic species of the
genus Carabus - C. croaticus and C. caelatus and to determine the true number of subspecies
and phenotypic variants. A significantly smaller number of subspecies have been suggested,
and geometric morphometric methods have also proved to be useful for intraspecific
delimitation, overcoming traditional linear morphometry problems. An analysis of the carabids'
assemblages after 25-years indicated a decrease in the number of mountain specialists and the
spread of generalists within the Risnjak National Park. The absence of endemic species Molops
alpestris, Pterostichus unctulatus and Trechus croaticus in the catch highlight the importance
of further continuous monitoring of carabids' assemblages to take accurate and well-timed
conservation measures.
