Sažetak
Peat bogs are generally characterised by great internal diversity that provides a plethora of various aquatic and semiaquatic habitats. Data on microdistribution and ecology of aquatic macroinvertebrates from the Southern Europe, including the Western Balkan peat bogs, are very scarce. The current study was conducted at the largest peat bog in Croatia influenced by the rapid successional changes causing its area to decrease significantly. Aquatic macroinvertebrates were sampled at four main habitat types: lake, hollow, ditch and pool. Sampling was conducted monthly during one vegetation season, from April to October 2015, using a 25x25 cm benthos net. In total, we recorded taxa from 18 different taxonomic groups, with aquatic insect orders and Crustaceans having the highest richness. Crustaceans, Diptera and Coleoptera were the groups recorded in the highest densities. However, our study shows that the aquatic macroinvertebrate assemblages in the Đon močvar peat bog differ between studied microhabitats, most probably related to differences in physicochemical water properties of studied habitats. Among the environmental variables analysed, physical water properties (such as temperature, depth and habitat size) were the most important in affecting the spatial distribution of aquatic macroinvertebrates at this peat bog. Our study supports the view that the peat bogs in Croatia are extremely endangered habitats. With the current trends of decreasing traditional agricultural activities, it is of a crucial importance to protect Croatian largest remaining peat bog from rapid successional changes.
