Abstract

Istraživanje faune mrava provedeno je tijekom ljeta 2018. godine na pokušalištu Maksimir Agronomskog fakulteta Sveučilišta u Zagrebu i poluprirodnim staništima u njegovoj neposrednoj blizini. Mravi su sakupljani pomoću lovnih posuda postavljenih na devet lokacija, a uključivale su po tri jednogodišnje i višegodišnje kulture, te tri poluprirodna staništa kao kontrolu. Ukupno je prikupljeno 367 jedinki mrava, te je identificirano 12 vrsta koje pripadaju u četiri potporodice. Najveća brojnost vrsta (9) utvrđena je na kontrolnim površinama, zatim slijede višegodišnje kulture (8 vrsta), dok je najmanja brojnost vrsta (6) utvrđena kod jednogodišnjih kultura. Brojnost mrava statistički značajno se razlikovala između jednogodišnjih kultura i kontrolnih površina, te između jednogodišnjih i višegodišnjih kultura. Izostanak pojedinih agrotehničkih zahvata u višegodišnjim kulturama, osobito obrade tla, utjecao je na veću brojnost i raznolikost mrava u odnosu na jednogodišnje kulture u kojima je provedena duboka obrada tla, te najveći broj agrotehničkih zahvata u biljnoj proizvodnji. Na području Zagreba determinirano je osam novih vrsta mrava (Formica cunicularia Latreille, 1798; Lasius myops Forel, 1894; Ponera coarctata (Latreille, 1802); Tetramorium semilaeve André, 1883; Aphaenogaster subterranea (Latreille, 1798); Myrmica scabrinodis Nylander, 1846 i Solenopsis fugax (Latreille, 1798)), a pronalazak vrste Tetramorium atratulum (Schenck, 1852) predstavlja prvi nalaz za područje Hrvatske. Fauna mrava po prvi put je proučavana na poljoprivrednim staništima u Hrvatskoj, a rezultati istraživanja pokazali su da mravi mogu biti vrlo dobri bioindikatori u procjeni kvalitete tla i načina gospodarenja tlom.

Abstract (english)

The research of ant fauna was conducted in summer 2018 on experimental field Maksimir of Faculty of Agriculture, University of Zagreb and the surrounding semi-natural habitats. Ants were collected using pitfall traps on nine locations, on three annual and three perennial crops and in three semi-natural habitats as control. A total of 367 specimens were collected, identifying 12 species within four subfamilies. The largest abundance of species (9) was determined in control plots, followed by perennial crops (8 species), while only 6 species were found in annual crops. There was a statistically significant difference in ant abundance between plots with annual crops and control plots, and between plots with annual crops and plots with perennial crops. Absence of certain agrotechnical interventions in perennial crops, particularly cultivation, had an impact on greater abundance of ants compared to annual crops where deep cultivation and the largest number of agrotechnical interventions in crop production were conducted. Eight new ant species were found in Zagreb area ((Formica cunicularia Latreille, 1798; Lasius myops Forel, 1894; Ponera coarctata (Latreille, 1802); Tetramorium semilaeve André, 1883; Aphaenogaster subterranea (Latreille, 1798); Myrmica scabrinodis Nylander, 1846 i Solenopsis fugax (Latreille, 1798)), and species Tetramorium atratulum (Schenck, 1852) was found for the first time in Croatia. Ant fauna was researched for the first time on agricultural habitats in Croatia, and the results show that ants can be very good bioindicators of soil quality and land management.
