Sažetak
Dry riverbeds are, in addition to lotic and lentic habitats, a phase of the intermittent river cycle. These hydrologically dynamic ecosystems are defined by flow intermittence and characterized by the variability of aquatic, semi-aquatic, and terrestrial communities. This study aimed to identify dispersal patterns of flying invertebrates during the dry riverbed colonisation. The study was conducted at the intermittent Krčić River, located at the foot of the Dinara Mountain, using cross-vaned windowtraps set in two main habitat types: dry riverbed and riparian habitats. Samples were collected continuously for eight days in July, every 12 hours. Since wind potentially affects the colonization of the dry riverbed, wind speed and direction were also measured continuously. The order Diptera, primarily Phoridae family, prevailed in abundance in both studied habitat types, followed by the orders Coleoptera, Thysanoptera, and Hymenoptera. The activity patterns of flying invertebrates differed significantly between day and night, abundance being positively correlated with wind speed during daytime. Furthermore, statistically significant differences were recorded for Coleoptera and Thysanoptera abundances between the studied habitat types. Dry riverbed colonization trend from the riparian habitat (lateral effect) was detected, while the colonization along
