Sažetak
Impact of climate change on freshwater ecosystems is one of the main scopes in current limnology. Such studies are focused on the recovery of affected areas where the dynamic of recolonization by benthic community has a key role. Nevertheless, knowledge about this process is still scarce. With the aim to get a basic insight into the recolonization process, a comprehensive study in freshwater habitat with stable environmental conditions without anthropogenic disturbance was conducted in Jankovac spring area in Papuk Nature Park. Preliminary study was done in June 2013, and later repeated in June 2018, when the methodology was greatly improved, as: i) it was conducted for longer period (every 12 hours for six days) ; ii) diverse artificial substrates were used (differing in colour, structure and stability) by replicate procedure ; iii) physical and chemical parameters of water were studied in detail, and iv) the canopy coverage of the habitat was analysed. Composition of benthic invertebrate community was similar in both studies with the most numerous organisms of 1 – 2 mm body size, such as insect larvae of Ephemeroptera and Diptera (Chironomidae and Simuliidae). The higher abundance of benthic invertebrates occurred in uncovered, light area of the habitat, regardless to the substrate type. Unfixed substrates were more actively colonized than the fixed ones. Current velocity was proven to be the key parameter influencing colonization dynamics. Many results of this study help in better understanding of the benthic invertebrate colonization, which will serve as a basis for future more specific studies.
