Sažetak
Planktonic ciliates, as well as the entire microzooplankton size-fraction represent the important components of the planktonic food webs, characterised by high biomass and intensive population dynamics. Due to their ability to adapt rapidly to ecosystem changes, small-sized zooplankton can act as good indicators of the marine ecosystems trophic state. After the activation of new modern sewage system in the eastern part of Kaštela Bay in November 2004, the potential changes in microzooplankton community composition, quantitative structure and seasonal variability were studied for more than a decade. Samples were collected seasonally during three periods: before (2001-2004), after (2005-2008) and ten years after the activation of new sewage system (2015-2017). The changes were best reflected in nonloricate and tintinnid ciliates, evident in the considerably reduced variability of their abundances and increased tintinnid biodiversity in the period after 2004. However, the absence of ciliate summer peaks and reduction of average abundances were statistically significant only at the larger time scale (ten years after). This indicated that apart from the changed trophic state, other environmental parameters affected the microzooplankton community in the period 2015-2017. Changes in seasonal dynamics of the target microzooplankton groups, particularly of ciliates, were confirmed by the Self Organising Map analysis. Further multi-annual investigations (from 2001 onwards) of the trophic relationships within the planktonic food web and the assessment of importance of abiotic parameters are needed for better understanding of the small-sized zooplankton response to environmental changes in this enclosed coastal location.
