AB  - Various studies report contrasting results on the substrate-type effect on diatom community composition, but the particularly important question is whether or not it affects diatom-based assessments of water quality. We investigated whether the substrate type is a significant predictor of the diatom community composition and if it affects lake water quality assessment based on diatom indices. This study took place in Sava Lake (Serbia). We used glass, ceramic, willow and yew tree tiles as artificial substrates for periphyton development, and pebbles from the lake littoral as natural substrate. Results revealed differences in both the diatom community composition and diatom indices values related to the substrates. A distinction was recognized between natural, artificial wooden, and artificial inert substrates. However, the final lake quality assessment based on diatom indices was more or less similar in all substrate types in our study, and depended on value ranges associated with water quality classification and on diatom index choices. Artificial substrates in our study did show potential as an alternative for natural substrate, but further studies are required, particularly in various types of lentic ecosystems to confirm our findings and support artificial substrate employment in lake water quality assessment.
AB  - Diverses études rapportent des résultats contrastés sur l'effet du type de substrat sur la composition de la communauté de diatomées, mais la question particulièrement importante est de savoir si cela affecte ou non les évaluations de la qualité de l'eau basées sur les diatomées. Nous avons cherché à savoir si le type de substrat est un prédicteur significatif de la composition de la communauté de diatomées et s'il affecte l'évaluation de la qualité de l'eau des lacs basée sur les indices de diatomées. Cette étude a eu lieu dans le lac Sava (Serbie). Nous avons utilisé des carreaux de verre, de céramique, de saule et d'if comme substrats artificiels pour le développement du périphyton, et des galets du littoral du lac comme substrat naturel. Les résultats ont révélé des différences dans la composition de la communauté de diatomées et dans les valeurs des indices de diatomées liées aux substrats. Une distinction a été reconnue entre les substrats naturels, artificiels en bois et artificiels inertes. Cependant, l'évaluation finale de la qualité du lac basée sur les indices de diatomées était plus ou moins similaire dans tous les types de substrats de notre étude, et dépendait des plages de valeurs associées à la classification de la qualité de l'eau et des choix d'indices de diatomées.

AB  - The main aim of this study was to investigate the application of benthic diatoms and the efficiency of diatom
indices in water ecological assessment of rivers in Serbia, as well as the influence of trout farms on rivers water
quality. Research was conducted in one year period along the Crnica and Radovanska rivers (Eastern Serbia), in
11 sampling sites (taking into account the position of trout fish farms that are built on both rivers). Results
showed that fish farms affect the physical and chemical parameters, as well as diversity of the epilithic diatom
assemblage along the rivers. Canonical correspondence analysis (CCA) indicated that among tested physical and
chemical parameters, conductivity “EC”, water hardness “WH”, sulfates “SO42-”, ionized ammonia fraction “NH4+”,
nitrates “NO3–
“, “pH”, mud, stone and depth were the most important variables affecting the distribution of
diatom species. A total of 206 epilithic diatom taxa were recorded in the Radovanska and 170 in the Crnica River.
Based on diatom indices, trout fish farms have no significant negative impact on the water quality of the
investigated rivers (indices are not enough sensitive). Redundancy analysis (RDA) showed a high degree of
correlation between the majority of indices which mostly indicated to good water quality of studied rivers. TID
and TDI were the only two indices indicating moderate and poor water quality of both rivers. Water quality based
on the TIDRS, the first proposed diatom index for Serbia was differ in two classes in most sites compairing with
TID.

AB  - Aerophytic phototrophs, colonizers of different substrates exposed to air, among which are rock substrates in cave habitats, are in general not sufficiently investigated and studied. From the ecological point of view, seasonal/temporal variations and parameters that influence aerophytic phototrophic communities through seasons still remain largely unknown. Seasonal analysis of phototrophic microorganisms from biofilms developed at entrances of Samar and Jezava caves in Eastern Serbia was performed four times a year. All identified phototrophic representatives were assigned to a certain division or group. The relationship between documented groups and different measured, determined and observed ecological parameters was illustrated using principal component analysis (PCA). A high diversity of cyanobacteria and algae was observed as a result of seasonal sampling: 141 taxa in Samar and 61 taxa in Jezava Cave. Cyanobacteria were dominant in both caves (coccoid forms prevailing) and were followed by Bacillariophyta. Bacillariophyta were positively correlated with light intensity and sites where seeping water was present, and cyanobacteria with water content in biofilm, Chl a and relative air humidity. Higher diversity of phototrophs was documented in December and March, and lower in May and August in both caves with Chl a values having the same trend as the diversity of phototrophic microorganisms. This was especially the case with biofilms in which diversity was more prone to seasonal changes and where Cyanobacteria dominated. Only 24 taxa were documented during all four seasons in Samar Cave (Cyanobacteria, Bacillariophyta and Chlorophyta representatives) and three in Jezava Cave (Cyanobacteria only).

AB  - A total of 15 Navicula taxa were recorded in epilithic
communities occurring in seven rivers of Serbia, all of
which are new to the diatom flora of Serbia. The most
interesting of them are N. splendicula and N. moskalii. When
observing N. splendicula specimens under SEM, we noticed
a characteristic silicate tongue in the center of raphe ends,
which had not been previously reported in the available
literature. The insufficiently researched distribution of
N. moskalii and scarce autecological information on the
taxon prompted us to provide new details about the species
in this study. These findings clearly indicate the need for
further comprehensive research that would provide new
information on rare taxa.

AB  - Rod Navicula 1822. godine je opisao Bory de St. Vincent obuhvativši birafidne izopolarne taksone vretenastog oblika. Vrste roda Navicula karakterišu poprečne pruge izgrađene od jednog niza pora (lineola), filiformna rafa i dva krupna hromatofora. Prema podacima iz Algaebase (Guiry i Guiry 2018) rod Navicula obuhvata 1264 taksona.
Tokom 2011. i 2012. godine sakupljeni su epilitski uzorci silikatnih algi iz sedam reka Srbije (Rasina, Rača, Raška, Studenica, Mlava, Vrla i Radovanska reka). Rezultati su pokazali da je rod Navicula jedan od najzastupljenijih u istraživanim rekama. Od ukupnog broja identifikovanih taksona zabeleženo je 15 novih za floru silikatnih algi Srbije. Svi ovi taksoni preferiraju karbonatne, oligo- do eutrofne vode, sa pH većom od 7 i umerenom koncentracijom elektrolita. Nijedan od ovih taksona nije zabeležen sa značajnom brojnošću, ali je njihovo prisustvo važano sa aspekta biodiverziteta. N. moskalii se izdvaja kao retko zabeležen takson u Evropi (Cantontati i sar. 2017). Rezultati naših istraživanja šire njen areal, kao i opseg dimenzija valve, pružajući nove detalje o autekološkim karakteristikama taksona.
Ovi rezultati ukazuju na neophodnost detaljnijih i intenzivnijih istraživanja u cilju proširenja znanja o silikatnim algama Srbije.

AB  - Diatoms are a widespread group of organisms with well-known ecological preferences. Knowledge of their diversity is of great importance for assessing the environmental status of different aquatic ecosystems. The present study was
based on 55 different localities that included rivers, streams, channels, accumulations and salt marshes throughout Serbia. The results of this study expanded the diatom checklist by 80 taxa, including two new recorded genera (Fistulifera and Microfissurata) for Serbia. The data were obtained by combining light microscopy (LM) and scanning electron microscopy
(SEM) that provided reliable identification, which is very important in diatom diversity studies.

AB  - The main objective of this paper is to report new
information about the distribution and ecology of a
recently described diatom species, Geissleria gereckei.
The opportunity for updating the information on the
distribution and ecology of the species was provided by
the finding of well-developed G. gereckei populations on
the lithic material and bryophytes in the Raška and Mlava
rivers (Serbia). For several years after the first description,
G. gereckei has been known only from the type locality
and from another spring in the Dolomiti Bellunesi National
Park (the south-eastern Alps). After accurate LM and SEM
observations, we provide evidence for the occurrence
of the species also in the two above-mentioned rivers in
Serbia, as well as in the south-western and south-eastern
Alps. After an extensive literature search, it appears that the
species is known with certainty only from these sites. Our
observations and details from the literature suggest that
the species is able to occupy a much broader ecological
niche than the very-specific one observed at the time of
discovery. The two main determinants for the species’
occurrence appear to be the carbonate nature of the
catchments or aquifers, and the ability of the species to
be competitive in habitats or microhabitats exposed to
seasonal desiccation.

AB  - Epilithic diatoms from the Vrla River (Serbia) have been used to assess the ecological status of water. A total of 227 diatom taxa belonging to 50 genera were identified in the Vrla River during six research seasons with 13 dominant species recorded. Gomphonema (30 species), Navicula (28) and Nitzschia (26) were the most species-rich genera, followed by Pinnularia (12) and Encyonema (11). One taxa was recorded as new to Serbia - Geissleria acceptata. CCA grouped the diatom taxa into three main groups. The first group included taxa found at most of the sampling sites, the second group involved diatom taxa significantly positively correlated with the oxygen, while the third group showed positive correlation with temperature. RDA showed that some diatom taxa, including: Cocconeis placentula var. placentula, C. placentula var. lineata, C. pseudolineata and Mayamaea atomus var. permitis, are significantly positively correlated with temperature, while others, for example Achnanthidium minutissimum, Hannaea arcus, Nitzschia pura are mostly correlated with total phosphorus, alkalinity and water hardness. The ecological status of the Vrla River ranged from moderate, good to high. It was shown that according to the diatom indices, the ecological status of water downstream and upstream of a trout fish pond was slightly different.

AB  - The main objective of this study was to assess the ecological status of the Mlava River based on
epilithic diatoms and to test the use of diatom indices as a tool for estimating the quality of fl owing waters in
Serbia. Quantitative analysis showed that in April Achnanthidium minutissimum was dominant at each site,
except at the fi fth site, where Amphora pediculus was dominant. In July and September, Achnanthidium
minutissimum, Achnanthidium pyrenaicum, Amphora pediculus, Denticula tenuis, Diatoma vulgaris, Gomphonema
elegantissimum, Cocconeis pseudolineata and Cocconeis placentula var. lineata dominated. Detrended
correspondence analysis (DCA) was used to detect the major patterns of variation in species composition.
The fi rst DCA axis summarizes the distribution of the diatom community, mainly through temperature,
conductivity, oxygen and water hardness gradient. The second DCA axis was weakly correlated with few
variables. Based on the average values of the pollution sensitivity index (IPS), commission for economical
community metric (CEE) and biological diatom index (IBD), the water of the Mlava River belonged to water
class I during all three seasons. Values of the diatom-based eutrophication/pollution index (EPI-D) indicated
class II water quality. According to calculated trophic diatom index (TDI) values, water of the Mlava River
was characterized by intermediate nutrient concentrations during three seasons. Principal components analysis
was used to represent the correlation between diatom indices, and the highest correlation among the selected
diatom indices is seen between EPI-D, IPS and IBD.

AB  - The genus Navicula was originally described in 1822 by Bory de St. Vincent. The concept of Navicula has changed from extremely heterogeneous collective genus to a narrowly defined, apparently homogeneous genus. The group Navicula sensu stricto involves 250-300 species and the great majority of them live in fresh, inland waters, and few inhabit brackish waters (Lange-Bertalot 2001).
Knowledge about diatom biodiversity increase as a result of a more detail morphometric analysis of the frustula by light (LM) and scanning electron microscopy (SEM).
Navicula splendicula was described by Van Landingham (1975). According to Lange-Bertalot (2001) it is known to inhabit southern and central Europe, with certainty. Distribution of N. splendicula from 2001 till today become wider, but in published papers SEM micrographs, as well as the dimensions of frustula, were not given and specified. LM and SEM observation of species from Serbia (Rasina and Vrla rivers) showed a variation from literature data regarding dimensions of frustula and variability of the ultrastructure of the central raphe ends.
The poster illustrates all differentiating characters with brief notes on the ecology of the N. splendicula from two rivers in Serbia.

AB  - The aim of this paper is to present the distribution of Decussata hexagona, a new species in diatom
flora of Serbia. Seventy-two diatom samples were collected from six localities along the Vrla and
Rasina Rivers during 2011 and 2012. Decussata hexagona was recorded with single specimens or
low relative abundance (0.3%) from epilithic communities in seven samples from the Vrla River
and in one sample from the Rasina River. It was recorded in unusual epilithic habitats of running
neutral to low-alkaline waters with low ion content.

AB  - For the first time in Serbia, the presence of Didymosphenia geminata was recorded in lakes of the Šar Planina mountain (Urošević, 1994). Subsequently, it was observed in the rivers Danube, Tisa, Sava. Detailed range of D. geminata spreading in the waters of Serbia was given by Subakov-Simić et al. (2006). Throughout monitiring rivers and channels in Serbia we recorded expand of this species in norther part of Serbia, Vojvodina, in the channel Novi Sad-Savino Selo.
Diadesmis confervacea is diatom with a mainly tropical distribution. Majority of the findings in Europe originate from quiescent waters of botanical gardens and it is common in power plant discharges (Coste and Ector, 2000). They suggest it is invasive species that may spread further if global warming persists. While monitoring rivers and channels of Serbia from 2002 till 2013 we noticed the rapid expansion of distribution of D. confervacea. It occupied new habitats and nowadays can be found in the rivers Jegrička and Zasavica, as well in the channals Bački Petrovac-Karavukovo, Bečej-Bogojevo and Kikindski kanal in Vojvodina.

AB  - We compared epiphytic and epilithic diatom communities in the Raška River, and their use in river biomonitoring. The material was collected in April, June, August and November 2011, and March 2012 from 5 localities along the Raška River. The result showed high variation of the diatom species composition between this two micro-habitats. The most abundant genera were Navicula, Gomphonema and Nitzschia, but with higher diversity in epiphytic diatom community. During first season, Achnanthidium minutissimum and Gomphonema tergestinum were dominant taxa in epilithic, while A. minutissimum and Diatoma vulgaris in epiphytic diatom community. Epilithic diatoms are the favoured community for monitoring water quality. However, at any river, diatom species are located on various substrates at the same sampling site. For diatom diversity assessment it is necessary to investigate all micro-habitats. Our results point to a difference in values of TDI diatom index between macrophytes and stone samples. Is it necessary to investigate all micro-habitats, or is the type of substratum independent for water quality monitoring?
