Abstract
U Nacionalnom parku Krka zamijećeno je izraţeno širenje invazivne vrste pajasena (Ailanthus altissima) koje je uzrokovalo mjestimiĉnu izmjenu sporednih tokova rijeke Krke. U sklopu projekta za suzbijanje pajasena, jedinke invazivne flore su uklonjene na pokusnoj plohi i obnovljeni su presušeni tokovi. Time je poĉela i rekolonizacija akvatiĉkih zajednica. Tijekom 2017. i 2018. godine provela sam istraţivanje u trajanju 13 mjeseci o oporavku makrozoobentosa te fizikalno-kemijskom stanju vode na pokusnoj plohi. Istraţivaĉke postaje su bile: kontrolna lokacija u neprekinutom toku i ĉetiri lokacije u nanovo naplavljenim tokovima. Uzorke bentala uzimala sam kruţnim jezgrilom. Fizikalno-kemijski parametri vode mjereni su na licu mjesta ili u laboratoriju. Sveukupno je izolirano 17 taksonomskih skupina makrozoobentosa u kojima su dominirale liĉinke vodenih kukaca. Mjerenja fizikalnokemijskih parametara vode pokazala su oĉekivane sezonske promjene i podjednake uvjete na svim postajama. Izraĉunom Sørensenovog indeksa sliĉnosti, dokazana je velika sliĉnost sastava zajednica kontrolne i ostalih lokacija. Najveća gustoća makrozoobentosa bila je na lokacijama 2 i 3 koje su najbliţe kontrolnoj lokaciji. Raznolikost makrozoobentosa sliĉna kontrolnoj lokaciji uspostavljena je otprilike 3 mjeseca nakon obnove tokova. Primarno su obnovljene tokove kolonizirali maloĉetinaši, mušice svrbljivice i trzalci. Vodencvjetovi, tulari i komarĉići kolonizirali su nanovo naplavljene tokove mjesecima nakon prethodno navedenih skupina.
Abstract (english)
Spread of the invasive species Ailanthus altissima was observed in the Krka National Park causing local changes in the Krka River side-streams. As part of the spreading control project, invasive plants were removed from the experimental plot, dried streams were restored and recolonization of aquatic communities started. I conducted a research on the recovery of macroinvertebrate community and the physico-chemical state of water in that area lasting for 13 months in 2017-2018. The research stations were: control location in uninterrupted stream and four locations in newly flooded streams. I took benthal samples with a circular corer. Physico-chemical parameters of water were measured on site or in the laboratory. In total, 17 taxonomic groups of macroinvertebrates were isolated, mostly larvae of aquatic insects. Water physico-chemical parameters measurements showed expected seasonal changes and same conditions at all locations. Sørensen's index of similarity calculation proved similar composition of the communities among all tested locations. Locations 2 and 3 (closest to the control location) showed the highest density of macroinvertebrates. Macroinvertebrate diversity similar to the control site was established after approximately 3 months. Newly flooded streams were firstly colonized by worms, non-biting midges and blackflies. Mayflies, caddisflies and biting midges colonized them months after.
