Sažetak
Karstic lake ecosystems are specific and have great ecological significance. They provide unique habitats to numerous organisms, macroinvertebrates as well as planktonic organisms, the latter representing the reasons why it is important to understand how those complex and diverse ecosystems function. Dinoflagellates are an important part of phytoplankton community as they sometimes contribute significantly to the total phytoplankton biomass. Results in this paper were obtained during phytoplankton ecology research with the objective to document armored dinoflagellate species. The taxonomic interest for dinoflagellates started during project of comparative studies on centric diatoms and dinoflagellates of Hungarian and Croatian large rivers, reservoirs and lakes and continued with project of taxonomical comparative studies on dinoflagellates species on the same area. During the projects, phytoplankton samples collected in period from 1995 to 2006 on 21 localities in Croatia were reviewed. Preliminary results of first project were presented on Croatian Biological Congress in 2006 as first annotated check list of 20 free-living armored dinoflagellates of the Croatian freshwater systems. A main goal of the paper was to present detailed taxonomic morphological features of armored dinoflagellate taxa assigned to the genera Ceratium, Peridinum and Peridiniopsis in Croatian freshwater karstic systems. Taxonomical observations and general morphological structures are based on SEM and light micrographs. Results present data from scanning electron microscopy, sketchy drawings of main distinguishing features and species-specific ecological preferences and/or tolerance in karstic systems. Also, taxonomical issues of problematic species, such as Peridinium umbonatum/incospicuum group, are shortly discussed.
