Sažetak
Lakes and ponds increased habitat heterogeneity and, in particular, invertebrate biodiversity. These ecosystems are particularly sensitive to diverse anthropogenic impacts (leaching of soil and fertilizers, wastewater inflow). Eutrophication (increased input of nutrients, nitrates and phosphates) is one of the most pronounced detorioration in standing waters and led to the degradation of waterbody. Besides chemical water quality factors, biological water quality factors are very importan din consideration of ecosystem functioning. Zooplankton plays important and pivotal role in the matter cycling and energy transfer through the foodwebs in the deep and shallow waterbodies. Three main groups of zooplankton: Rotifera, Cladocera and Copepoda, are often underestimated in the studies and are not equally represented among themselves and in comparison to phytoplankton, macroinvertebrates and fish. These microaquatic organisms are reliable indicators of the water quality, according to their main traits: diversity, density, biomass and feeding structure, and could indicate the increase or decrease system productivity, i.e. nutrients input. In this survery we will present main zooplankton traits in three types of threatened ecosystem: (i) karst lakes (Visovac Lake, Croatia ; Shkodra Lake, Albania ; Ohrid Lake, Macedonia) ; (ii) permanent shallow waterbodies in temperate climate (inland Croatia) and (iii) ephemeral waterbodies in Mediterranean climate (Adriatic Sea, Croatia). Overall trends of detoriated water quality were exhibited across studied ecosystem: decreased biodiversity, increased abundance of few species, decrease in the specimen body size and transition of feeding preferences, from algivorous to detritivorous. In deep karst lakes prevailed algivorous, large-sized zooplankton, while with increaded water quality parameters small-sized detridivores overtook domination. Fish and macrophytes presence was revealed as important drivers in the biocoenosis structuring. This study highlights importance of zooplankton in the ecosystem functioning, to sustain good water quality and in lake restoration.
