Sažetak
Considering macroinvertebrate's inevitable role in energy flow of ecosystem, they are regarded excellent indicator of total ecological condition. Perceiving and researching both the community structure and biology of specific taxa therein, is fundamental for understanding the complex interactions within ecosystem. Accordingly, the aim of our research was to define and compare macroinvertebrate communities at the spring and at the tufa barrier of Plitvice Lakes (Croatia). Both sites are part of the karst landscape: a cool and environmentally stable, rheocrene spring of Bijela rijeka and a dynamic limestone depositing site at the tufa barrier Labudovac. Secondly, we aimed to determine the size structure and the secondary production of the dominant taxa. Physicochemical parameters of water were stable at the spring site and expectedly fluctuated at the tufa barrier. The most abundant taxon at the tufa barrier were non biting midges whilst stoneflies were dominant at the spring site. Since non biting midges are currently identified to family level, further ecological analyses were not advisable so we focused on the stoneflies. Stoneflies from both sites predominantly belong to Protonemura genus. After measuring the width of head capsules, using Scott's formula we found that Protonemura develops over a 14 stage cycle and individual mass 83 times during the life cycle. Secondary production calculated using the Size-frequency method was approximately 5 g per m²/year.
