“…It is an early colonizing species (Falasco et al, 2012) reported to successfully recolonize and develop dense populations in the fast water substrata after repeated annual dry phases (Della Bella et al, 2017). The properties of Krčić Spring corresponded to water associated with high abundance and frequency of A. minutissimum, like streamflow variability and slighty alkaline conditions (Noga et al, 2014;Della Bella et al, 2017;Jakovljević et al, 2016). A. minutissimum is reported as a pioneering species during the initial processes of biofilm formation (Sekar et al, 2004;Leinweber and Kroth, 2015).…”

-Microbial mats represent complex communities where cyanobacteria and diatoms as key organisms provide shelter for diverse assemblages of aquatic invertebrates, like the small stygophilous amphipod Synurella ambulans. Studies addressing such communities in the karst springs have rarely examined springheads, and have ignored intermittent springs. During high flow conditions the stygophilic crustaceans are flushed to the surface of a temporary stream Krčić where microbial mats prevent their drift and enables their successful retreat into underground in the periods of drought. The objective of this study was to characterize the microbial mat community of the Krčić Spring as a shelter for S. ambulans during strong current and high water level. Representative samples for diatom and cyanobacterial species identification and composition, as well as the fresh mat material for potential animal activity and cyanobacterial phylogenetic analysis were collected. The most dominant diatom was Achnanthidium minutissimum, whilst Fragilaria capucina, Meridion circulare, Navicula cryptocephala and Nitzschia palea had abundance greater than 0.5%. Morphological observations of cyanobacteria revealed that Phormidium favosum was the most dominant, with Hydrocoleum muscicola as a subdominant. Cyanobacterial phylogenetic relationship revealed two distinct clusters: (i) "Phormidium cluster", confirming morphological observations in both winter and spring samples, and (ii) "Wilmottia cluster", a first report for Croatia and found exclusively in the winter sample. Laboratory observations revealed a small stygophilic amphipod S. ambulans, hiding and feeding inside the pockets of fresh microbial mat. The intermittent Krčić Spring as a predator-free and competitor-free ecosystem provides a spatiotemporal conformity between microbial mat and stygophilous amphipod.Keywords: Microbial mat / cyanobacteria / diatoms / amphipods / karstic spring Résumé -Le tapis microbien comme microhabitat refuge pour les amphipodes dans une source karstique intermittente.

“…Having in consideration the highest percentage of indicator taxa, the most applicable in our study was the IPS index. Jakovljević et al (2016) also gave the recommendation for use of the IPS index in the research of benthic diatoms in water quality assessment of the Mlava River in Serbia. The index developed for littoral diatoms, TDIL, had the lowest percentage of indicator taxa.…”

Biodiversity of diatoms and applicability of diatom indices in biomonitoring based on littoral epiphytic samples of Lake Modrac were investigated. Diatoms were taken mostly from Phragmites australis stems in 2017, during which physical and chemical parameters of the water were measured. A total of 85 diatom taxa were identified. Gomphonema (13 spp.), Navicula (11 spp.), and Nitzschia (8 spp.) were the most abundant genera. Obtained values of trophic indices (TID, TvD, and TDIL) pointed to meso-to eutrophic status for most localities, while values of the IBD, EPI, -D, and IPS indices indicated good ecological status, except for localities at the mouth of 2 main tributaries which had moderate or poor ecological status. Based on the hierarchical group average clustering and nonmetric multidimensional scaling, 4 groups were identified, mainly related to the sampling period, with higher spatial variation in species composition during summer. Since environmental legislation in Bosnia and Herzegovina still does not provide detailed instructions on using diatoms in biological assessment, results of this study can be useful for the development of biomonitoring tools for lakes in Bosnia and Herzegovina.

“…For the second data set, basic descriptive statistics were calculated using STATISTICA 6.0. Since the recommended class limits exist only for IPS and CEE in the Serbian legislation, for the EPI-D and TDI indices we used the boundaries from some EU countries as an illustration of their applicability to our river systems [3].…”

“…The species recorded in the Lasovačka and Lenovačka streams are widely distributed in freshwater ecosystems [15]. The most numerous taxa of Gomphonema and Navicula are common in streams of Europe and Serbia [3,19]. During the study, C. budensis was recorded in the Lasovačka River, and in the diatom flora of Serbia for the first time [20].…”

The development and improvement of the monitoring system of rivers according to the requirements of the Water Framework Directive (WFD) is essential for all European states because assigning a wrong ecological status class (misclassification) to a water body can have significant economic consequences. In order to point out some of the key issues of WFD implementation in Serbia, we conducted a one-year study of the composition and abundance of diatoms in the phytobenthos in two streams, the Lasovačka and Lenovačka, in eastern Serbia. The physicochemical quality elements were also used in the assessment of their ecological status. The diatom community exhibited a higher species richness in the Lasovačka (88 taxa) than in the Lenovačka stream (63 taxa). Such a detailed study enabled us to record some of the rare taxa, e.g. Caloneis budensis in the Lasovačka, which was the first finding of this species in Serbia. The Lasovačka and Lenovačka streams were downgraded to moderate and poor ecological status, respectively, because of the high nitrogen load. Since the monitoring results based on the diatom indices resulted in the assignment of two streams to a good ecological status, the possible reason for the mismatch between the biological and physicochemical quality elements could be due to the lack of analysis of benthic invertebrate fauna or the application of diatom indices that are insufficiently sensitive to the specific environmental pressure. The results of this study show that conducting a comprehensive ecological investigation of rivers within the framework of the WFD in Serbia is urgently needed.
