20.500.12556/RUL-170192 Združba migetalkarjev v majhnem vodnem telesu Ciliate community in a small water body Raziskovali smo združbo prostoživečih migetalkarjev (Ciliophora) v zadrževalniku Podutik, ki je majhno vodno telo na obrobju Ljubljane. Z raziskavo smo želeli pridobiti prve podatke o vrstah migetalkarjev na tem območju in ovrednotiti njihovo pestrost v povezavi z okoljskimi dejavniki v zadrževalniku. Pridobili smo podatke o temperaturi vode, raztopljenem kisiku, pH, prevodnosti, skupnih raztopljenih snoveh, Secchijevi globini, globini vode, biokemijski porabi kisika, koncentraciji nitratnih in ortofosfatnih ionov, ter o pretoku vode in velikosti zadrževalnika. Poleg tega smo z uporabo svetlobne mikroskopije in tehnike DIC, glede na morfologijo določili vrste migetalkarjev, ki smo jih našli v naših vzorcih, in v literaturi poiskali informacije o njihovih ekoloških značilnostih. Rezultati so pokazali, da vrste, ki so v spomladansko-poletnem času prisotne v zadrževalniku, lahko pripišemo različnim združbam migetalkarjev. Ob pregledovanju literature smo opazili povezavo med vrstno sestavo in številom vrst migetalkarjev ter značilnostmi ekosistema. Lastnosti ekosistema, ki imajo največji vpliv so velikost, globina vode, prosojnost vode, vodno rastje in količina raztopljenega kisika. Pestrost migetalkarjev v zadrževalniku Podutik je primerljiva z drugimi vodnimi telesi po svetu, ki imajo podobne značilnosti. Poleg tega smo ugotovili pozitivne spremembe v obrežnem rastju, kot rezultat naravne sukcesije po sanacijskih delih. Naši rezultati prispevajo k poznavanju migetalkarjev v celinskih vodnih ekosistemih in podajajo osnovo za nadaljnje raziskave migetalkarjev v Sloveniji. We investigated the community of free-living ciliates (Ciliophora) in the Podutik reservoir, a small water body on the outskirts of Ljubljana. The aim of the study was to obtain the first data on the ciliate species in this area and to evaluate their diversity in relation to the environmental factors of the reservoir. We obtained data on water temperature, dissolved oxygen, pH, conductivity, total dissolved solids, Secchi depth, water depth, biochemical oxygen demand, nitrate and orthophosphate ion concentrations, and flow and reservoir size. In addition, we used light microscopy and DIC technique to determine the species of ciliates found in our samples according to their morphology and we searched the literature for information on their ecological characteristics. The results showed that the species present in the reservoir during the spring-summer time can be attributed to different communities. While reviewing the literature we observed a correlation between the species composition and abundance of species and ecosystem characteristics. The ecosystem characteristics that have the greatest influence are water body size, water depth, water transparency, aquatic vegetation, and dissolved oxygen. The diversity of ciliates in the Podutik reservoir is comparable to other water bodies around the world that have similar characteristics. In addition, positive changes in the riparian vegetation have been observed as a result of natural succession following maintenance works. Our results contribute to the knowledge of ciliates in inland aquatic ecosystems and provide a basis for further research on ciliates in Slovenia. migetalkarji biodiverziteta ekološki dejavniki majhno vodno telo zadrževalnik Podutik Slovenija ciliates biodiversity ecological factors small water body Podutik reservoir Slovenia true false false [D.
