Abstract

Faunistička istraživanja mrava u Mediteranu, posebice u poljoprivrednim sustavima, kod nas su vrlo rijetka. Budući da je mediteransko područje bogato vrstama, a način gospodarenja u poljoprivredi može dodatno utjecati na raznolikost vrsta, istražena je fauna mrava u maslinicima i vinogradima na području Zadarske županije. Uspoređeni su indeksi raznolikosti između područja s različitim načinima upravljanja; u maslinicima i vinogradima s integriranom i ekološkom zaštitom bilja u kojima se koriste različite skupine pesticida, te prirodnom staništu bez gospodarenja, gdje nije bilo uporabe pesticida. Mravi su uzorkovani tijekom vegetacijske sezone u 2018. godini koristeći metodu stresanja, Tullgrenove lijevke i lovne zamke. Vrste su određene morfološki i metodom barkodiranja DNA te je utvrđeno 14 vrsta mrava. Pronađene vrste Aphaenogaster picena i Aphaenogaster balcanica su endemske, te su rijetki nalazi za Hrvatsku. Sve sekvence mravljih vrsta koje su određene u ovom istraživanju bile su prisutne u bazi podataka Nacionalnog centra za biotehnološke informacije (NCBI). Metode lova su utjecale na sastav i brojnost vrsta. Prema prikupljenim podacima, maslinici s integriranom zaštitom bilja u usporedbi s ekološkim maslinicima, imali su manju raznolikost. Stoga bi se utjecaj različitih načina gospodarenja u maslinicima na bioraznolikost mrava mogao detaljnije istražiti proučavanjem zajednica mrava na većem broju ploha.

Abstract (english)

Faunal research on ants in the Mediterranean area of our country, especially in agricultural systems, is very rare. Since the Mediterranean area has high species richness, and the way of management in agriculture can further affect the diversity of species, the ant fauna in olive groves and vineyards in the Zadar County was investigated. Diversity indices were compared between areas with different management modes; in olive and vineyard crops with integrated and ecologically based plant managements in which different groups of pesticides are used, and in natural habitat without management, where there was no use of pesticides. Ants were sampled during the 2018 growing season by using beating branch method, Tullgren funnels, and pitfall traps. Species were identified morphologically and by DNA barcoding, compiling the final list of 14 ant species. The found species of Aphaenogaster picena and Aphaenogaster balcanica are endemic, and are rare finds for Croatia. All sequences of determined ant species were present at the National Biotechnology Information Center (NCBI) database. Sampling methods influenced the composition and abundance of species. According to the collected data, olive groves with integrated plant management, compared to organic olive groves, had less diversity. Therefore, the impact of different management practices in olive groves on ant biodiversity could be investigated in more detail by studying ant communities on a larger number of plots.
