Abstract

U proljeće i jesen 2016. godine provela sam istraživanje makrozoobentosa sedrene barijere Labudovac i izvora Bijele rijeke. Cilj istraživanja bio je utvrditi dominantne svojte makrozoobentosa, odrediti i usporediti uzrasnu strukturu obalčara s dva funkcionalno i geografski razdvojena lokaliteta Plitvičkih jezera (izvor i sedrena barijera) te eventualne razlike objasniti učincima različitih ekoloških čimbenika. Fizikalno-kemijski pokazatelji vode ukazuju na konstantne uvjete na izvoru Bijele rijeke te na vrlo oscilirajuće uvjete na barijeri Labudovac. U makrozoobentosu barijere Labudovac dominiraju trzalci (Chironomidae), dok su na izvoru Bijele rijeke najbrojniji obalčari (Plecoptera). Obalčari s oba lokaliteta dominantno pripadaju rodu Protonemura. Mjerenjem širina njihovih glava, svrstala sam ih u 10 veličinskih razreda i načinila ukupnu sezonsku sliku uzrasne strukture obalčara iz roda Protonemura. Sezonske razlike u veličinskim razredima odgovaraju opisanom univoltnom životnom ciklusu obalčara.

Abstract (english)

The aim of this study was to determine the dominant taxes of macroinvertebrates, seasonal size structure of stoneflies and explain prospective differences by environmental factors at two different sites (spring and tufa barrier). The study was carried out in spring and autumn of 2006 at the Plitvice Lakes National Park, at the tufa barrier Labudovac and at the spring of Bijela rijeka. The physical and chemical parameters of water indicate constant conditions at the spring of Bijela rijeka and very variable at the barrier Labudovac. Dipteran family Chironomidae was the dominant taxon at the barrier Labudovac and stoneflies (Plecoptera) were dominant at the spring of Bijela rijeka. Stoneflies from both sites predominantly belong to Protonemura genus. After measuring the width of head capsules, I aligned them into the 10 size classes and made the total seasonal size structure of Protonemura genus. Seasonal differences in size classes are according to described univoltine life cycle of stoneflies.
