dc.description.abstractIstraživanje je urađeno u cilju utvrđivanja obrazaca distribucije rodova Merodon Meigen, 1802 i Cheilosia Meigen, 1822 na području jugoistočne Evrope. Rodovi Cheilosia i Merodon su najbrojniji fitofagni rodovi osolikih muva, a jugoistočna Evropa je izabrana kao posebno interesantno područje analiziranja distribucije vrsta zbog specifične kombinacije istorijskih, abiotičkih i biotičkih faktora koji određuju distribuciju. Na području jugoistočne Evrope registrovano je ukupno 202 vrste istraživanih rodova; 121 vrsta pripada rodu Merodon, a 81 vrsta pripada rodu Cheilosia. Broj od preko 200 vrsta pokazuje da je jugoistočna Evropa područje od izuzetnog bogatstva vrsta rodova Merodon i Cheilosia. Ovakav zaključak dopunjen je postojanjem čak 79 (39%) endemskih vrsta za područje jugoistočne Evrope. Prema gradijentu geografske širine, rodovi Merodon i Cheilosia pokazuju različit distributivni obrazac; uočava se da broj vrsta roda Merodon opada od juga ka severu, dok je distributivni obrazac obrnut za rod Cheilosia. U cilju analiziranja uticaja koje predeona struktura i promene u načinu korišćenja zemljišta imaju na vrste rodova Merodon i Cheilosia, sprovedena je predeono - ekološka analiza, uz pomoć GIS i odgovarajućih ekoloških softvera. Istraživanje pokazuje da postoji specifičan odnos između predeonih parametara i kompozicije vrsta istraživanih rodova - sa različitom osetljivošću rodova Merodon i Cheilosia na povezanost staništa i promene u načinu korišćenja zemljišta. Vrste roda Cheilosia su pozitivno korelisane sa poveznošću staništa a negativno korelisane sa svim ostalim predeonim parametrima, dok najveći broj vrsta roda Merodon pokazuje veću otpornost pri antropogenim promenama u ekosistemima. Ovakvi rezultati upućuju na diferenciraniji pristup pri upravljanju područjima, fokusiran na intenzitet korišćenja zemljišta (ispaše) i povezanost staništa. Istraživanje je obuhvatilo i evaluaciju staništa u okviru predela različitih karakteristika (prostorno i vremenski), primenom analize SyrphTheNet bazom podataka, koja uključuje vrste rodova Merodon i Cheilosia kao bioindikatore. Vrste rodova Merodon i Cheilosia su se pokazale kao veoma dobri indikatori koji mogu da ukažu na trenutni kvalitet istraživanog područja, kao i promene tokom dužeg vremenskog perioda. Analizom korelacije utvrđeno je da postoji povezanost između promena predeonih parametra u periodu od 25 godina i gubitka vrsta i kvaliteta makrostaništa na 17 istraživanih lokaliteta.sr
dc.description.abstractThe research has been carried out with the main aim to determine distributional patterns of two genera, Merodon Meigen 1802, and Cheilosia Meigen, 1822, in Southeast Europe region. Cheilosia and Merodon are the most numerous phytophagous hoverflies genera. Southeast Europe has been chosen as the specific region of interest to analyze species distribution due to its specific combinations of historical, abiotic and biotic factors that determine the species distribution. In the area of Southeast Europe, a total of 202 species of Merodon and Cheilosia have been recorded; 121 species belonging to the genus Merodon, and 81 species belonging to the genus Cheilosia, being a region exceptionally rich in species of the two genera. This conclusion has been supported by the fact that 79 (39%) endemic species has been found in the region. With regard to the gradient latitude, species of Merodon and Cheilosia genera show a different distribution pattern. More precisely, it has been shown that the number of Merodon species decreases from the south to the north, while the opposite pattern is true for the species of Cheilosia genus. In order to analyze the responses of hoverfly species to landscape structure, land cover analyses were performed using GIS tools and related ecological software. Merodon and Cheilosia species differ in their responses to land-use change and connectivity, with the latter genus being positively correlated with connectivity and negatively correlated with all other variables. Connectivity is the primary factor affecting Cheilosia, while most Merodon species demonstrated greater resistance to changes in human-modified ecosystems. These results suggest that different management efforts, focused on land-use intensity (grazing) or connectivity, seem to be appropriate when trying to conserve these taxa. In addition, the study examined the quality of habitats in landscapes of different characteristics (spatial and temporal), using SyrphTheNet database, in which species of the Merodon and Cheilosia genera were   used as bioindicators. Species of the two genera proved to be very good indicators of the current quality of the study area, as well as changes over a longer period of time. Correlation analysis has found a significant relationship between the changes of landscape parameters for a period of 25 years and the loss of species and quality macrohabitats on 17 investigated study sites.en
