Sažetak
Biodiversity and ecology of organisms living in karst subterranean habitats of Dinaric arc are poorly known. Data gaps are especially pronounced regarding species interactions and habitat variability. The main goal of this research was to enhance our knowledge of environmental conditions and communities present in habitats of Natura 2000 endemic species of subterranean bivalve Congeria jalzici, in order to better understand its ecology. Preliminary research of protists and other present microorganisms in eight speleological objects of wider area of Lipovo polje (Lika, Croatia) was performed during 2016 and 2018. It included microhabitats characterized by complete darkness. Biodiversity and abundance of protozoa was recorded, while presence of other microorganisms was recorded only at the higher taxonomical level. Focus was given to hygropetric habitats, which are of crucial importance for C. jalzici during the months characterized with hydrological minimums. Protozoa assemblages from hygropetric habitats in three speleological objects inhabited by C. jalzici formed separate clusters compared to other five caves where C. jalzici was not found. Especially diverse was polyphyletic group testate amoebas with 26 species, including some very rare species. Algae and cyanobacteria, transported probably by floods, were detected in some caves indicating specific hydrological connectivity. During this research, for the first time epibiotic ciliates on C. jalzici were registered and histologically confirmed. These findings show that assemblages of protists and other microorganisms in subterranean habitats, even though often neglected, should be considered in context of Congeria ecology especially because of their potential as bioindicators of environmental conditions.
