AB  - Charophyte research in SNR Zasavica started in 1998, and by 2010 a total of 9 species were recorded, most of which are categorized as critically endangered in Serbia. Charophytes was recorded primarily in small and ephemeral water bodies - puddles, ponds, even ruts, emphasizing significance of those for biodiversity. After the extraordinary results recorded in this period, the research continued in 2014 and in this paper we will present the results of the research until 2020. The results of this study confirmed two new taxa in the territory of Zasavica, Nitella gracilis and N. opaca, both critically endangered species in Serbia, but also the absence of one previously recorded taxon - N. capillaris. A shift in the representation of charophyte taxa was also noted, increased presence of the genus Chara representatives, and a decreased presence of the genus Nitella representatives was noted. The continuation of research, primarily in the direction of regular monitoring, will contribute to detailed mapping of the distribution of charophytes in Zasavica, but also to general knowledge of the ecology of rare and endangered species and their specific habitats. Finally, continuous monitoring will guide managers towards the selection of adequate protection measures in order to preserve the sensitive habitats and charophytes diversity in Zasavica.

AB  - According to the latest checklist, updated in December 2022, 25 species of charophyte algae are registered on the territory of Serbia. These data are gathered in a number of projects and finally integrated within the project related to the production of Red books and Red Lists of flora, fauna and fungi on the territory of the Republic of Serbia. The crown results of this work are preliminary Red Lists for all organism groups, including charophyte algae. The lists were produced in accordance with IUCN criteria, using an application especially created for the purpose of this project. According to IUCN criteria, all charophyte species registered on the territory of Serbia are Red Listed, that is, belong to one of the three categories – Critically Endangered (CR) – ten species, Endangered (EN) – seven species, and Vulnerable (VU) – seven species, except one species which is Data Deficient. The main factors endangering the flora of charophytes in Serbia are habitat fragmentation and desiccation, which were accordingly used as the main criteria to assess charophyte species status. Here we present the process as well as the results of the assessment and discuss the main factors of endangerment.

saline ecosystems are characterized by very specific and unique biodiversity Still,
biodiversity studies of saline habitats are mostly focused on lakes and ponds of natural
origin We investigated the biodiversity of submerged macrophytes, phytoplankton and
phytobenthos in the saline pond near Kikinda city (in Vojvodina, the northern province of
Serbia) that was artificially made by commercial clay digging and abandoned in the
landscape of the city suburban over time Collecting samples and field measurements
were conducted in July 2018 The dense cover of macrophytes in the litoral area consisted
of a carpet of Chara canescens with sparse specimens of Zannichellia palustris This is the
second currently known locality of C canescens in Serbia which was recently
rediscovered Despite the relatively wide range of this typically brackish species,
populations of C canescens are isolated, and it is worldwide considered
threatened/endangered and rare A total number of 27 algal taxa were detected in
phytoplankton A few taxa characteristic for saline or brackish water were detected
Oocystis submarina Merismopedia warmingiana Euglena proxima However, the majority
of detected taxa can be characterized as halotolerant In the phytobenthic community 15
diatom taxa were recorded The most dominant genus was Nitzschia 4 species) Brackish
water species were also recorded (e g Tryblionella hungarica T apiculata Navicymbula
pusilla first recorded in Serbian flora in 2018 was also discovered here Generally low
diversity, typical for saline habitats, was observed in relation to all communities, however
typically brackish, rare/endangered species were recorded Since our preliminary results
(obtained after one sampling occasion) indicate the potential for detecting specific
biodiversity in macrophyte, phytoplankton, and phytobenthic communities in one artificial
saline pond, we propose conducting a detailed study of this and other ponds of similar
origin.

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 importance of biofilms in caves, the diversity of microorganisms
in them, their mutual relationship and relationship with the substratum are among the advancing research topics in microbial biospeleology. This research is making contribution to the
knowledge about biofilms at cave entrances and phototrophic communities in them. In that
manner, biofilms from the entrance zone of the Petnica Cave were examined. Light microscopy showed that cyanobacteria were exclusively dominant phototrophs (34 taxa out of 39
total taxa recorded) with coccoid forms prevailing (28 taxa); simple trichal forms were present to a lesser extent, while heterocytous ones were completely absent. Genera Gloeocapsa,
Chroococcus,Gloeothece and Leptolyngbya were the most diverse. Four green algal genera
characteristic for aerophytic habitats (Apatococcus, Desmococcus, Haematococcus and
Trentepohlia) were also recorded, while Bacillariophyta were observed sporadically. Three
groups of sampling sites were distinguished based on recorded taxa, their richness and similarity, using non-metric multidimensional scaling (NMDS). Quantitative biofilm characteristics were also assessed – the content of chlorophyll a (Chl a) was determined, as well
as the contents of water, organic and inorganic matter. Chl a had a significant positive correlation with the content of organic matter (r=0.904, P=0.013).

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  - Phototrophic microorganisms from two caves in Serbia (Podpeć and Stopić) were examined. Samples were taken from the entrances where natural light was present, as well as from the inside caves near artificial light (lampenflora community). Cyanobacteria, Chlorophyta, Bacillariophyta and Xanthophyta were documented, with 51 taxa in total. The highest number of taxa recorded in the Cyanobacteria were coccoid cyanobacteria; Gleocapsa and Chroococcus were dominant. According to the redundancy analysis (RDA), Cyanobacteria were dominant at cave entrances while other groups (Chlorophyta, Bacillariophyta and Xanthophyta) were documented in lampenflora samples. Temperature, relative humidity, and light intensity were measured, as well as chlorophyll a concentrations and biofilm parameters (water, organic and inorganic matter content). Ecological parameters did not show significant variation, while light intensity de-pended on the position of sampling sites. RDA showed that the water content was higher in biofilm samples from cave entrances, while levels of inorganic matter were increased in lampenflora samples. The concentration of chlorophyll a did not show significant correlations with any of the measured ecological or biofilm parameters. Although the ecological parameters inside the cave did not show significant variation, they should be monitored because of the potential influence on the development of the lampenflora community that has a negative aesthetic impact on cave formations.

Temperature, relative humidity, and light intensity were measured, as well as chlorophyll a concentrations and biofilm parameters (water, organic and inorganic matter content). Ecological parameters did not show significant variation, while light intensity de-pended on the position of sampling sites. RDA showed that the water content was higher in biofilm samples from cave entrances, while levels of inorganic matter were increased in lampenflora samples. The concentration of chlorophyll a did not show significant correlations with any of the measured ecological or biofilm parameters. Although the ecological parameters inside the cave did not show significant variation, they should be monitored because of the potential influence on the development of the lampenflora community that has a negative aesthetic impact on cave formations.",

AB  - Charophyte species delineation is regularly based on a set of thallus morphological character- istics, but considering pronounced phenotypic plasticity, difficulties and doubts commonly occur in Chara species determination. DNA barcoding may contribute to solving these chal- lenges. Here we characterize Chara contraria with an unusual set of morphological character- istics, and specimens morphologically resembling Chara connivens collected in Serbia, by describing their morphological traits and analysing matK barcoding results. Our results indi- cated that dioecious Chara specimens, tentatively determined as Chara “connivens” based on morphological traits, were genetically more closely related to C. globularis. These Chara
“connivens” specimens formed a sister group to a monophyletic C. globularis cluster, suggesting that it may be neither C. connivens nor C. globularis. We strongly encourage further barcoding of C. “connivens” samples from freshwater, in order to find out if there are consistent genetic differences between the dioecious freshwater C. “connivens” and monoecious C. globularis. Barcoding of matK placed the monoecious Chara specimens, which based on morphological characteristics initially were determined as C. virgata, into the C. contraria group. This indicates that the microscopic traits which commonly are used for Chara species determination some- times are misleading. In general, our study challenges the commonly used phenetic species concept in Charophyte taxonomy and illustrates the importance of molecular approaches to evaluate the validity of morphological characteristics of the plant thallus in species delineation.

AB  - Phosphorus overenrichment of shallow ponds prevailing in wetlands leads to their eutrophication causing the collapse of those vulnerable habitats. The potential of phosphorus accumulation by periphyton developed on artificial substrata has been investigated in two shallow ponds (Baračka and Široki Rit) in northwest Serbia and compared to the same ability of plankton and metaphyton. The periphyton substrate carrier has been submerged from May to October. Both continuously (CS) and monthly developed (MS) periphyton were sampled. Autotrophic component of all investigated communities has been qualitatively assessed. Maximum accumulation of only 14.7 mg TP/m2 was recorded in three-month exposed periphyton CS. MS exposed from July to August reached maximal 12.7 mg TP/m2. Plankton community that was characterized by more diverse and abundantly developed algal component was more effective in phosphorus accumulation (0.7 mg/g dry weight) in comparison with dominantly inorganic and diatom-dominated periphyton in Baračka. Unstable conditions caused by recent revitalization (dredging organic matter and mud from pond basin—redigging) as well as rapid desiccation of Široki Rit disabled making an unambiguous conclusion about the efficiency of phosphorus accumulation among different communities, but suggested slight potential of phosphorus harvesting by metaphyton in this pond. Due to the shorter exposure time that brings the reduced risk of unpredictable changes in the ecosystem, as well as the considerable amount of accumulated phosphorus, large-scale application of one-month exposed periphyton developed on artificial substrates would be more advisable for phosphorus harvesting in nutrient affected shallow ponds.

AB  - Cyanobacterial blooms have become common all over the world, negatively affecting various ecosystem components. Planktothrix rubescens is a planktonic cyanobacterium that frequently causes blooms in temperate (mostly mesotrophic) lakes in Europe and, unlike other cyanobacteria, it is usually associated with ecosystem re-oligotrophication. The potential effects of P. rubescens on periphyton development have not been estimated in any recently published studies. The objective of the present paper was to assess how a Planktohrix rubescens bloom affects periphyton development in a temperate freshwater reservoir. A field study was performed in the Vrutci reservoir (western Serbia), where P. rubescens blooms have occurred since December of 2013. Periphyton was grown on glass slides that were incubated following lake stratification and sampled monthly from July to October of 2015. Dry mass, ash free dry mass and content of chlorophyll a, as well as composition of the community of developed periphyton, were estimated, together with P. rubescens biomass in the water column at the particular depths where substrates for periphyton were incubated. The metalimnetic bloom of P. rubescens induced calcite precipitation on the incubated substrates, which was reflected in obstructed colonization. The periphyton community composition was mainly determined by the depth gradient, which was potentially related to reduced light availability driven by shading effects caused by the P.rubescens bloom. Our results provide a significant update on periphyton ecology in relation to cyanobacterial blooms, elucidating complex interactions in the ecosystem. They also represent a stimulus for further studies on the capacity of P. rubescens for induction of calcium carbonate precipitation in lakes.

AB  - Due to life in extreme environments, cyanobacteria and algae from cave biofilms that form at the entrances or deep inside the cave around artificial lights are of increasing interest to many scientists. It is well-known that many phototrophic microorganisms are first to colonize exposed substrata and produce the organic matter on which other biofilm constituents relly. Many studies dealing with phototrophic microorganisms from biofilms focus on the diversity and community composition of cyanobacteria and algae, while quantitative assessments are rarely implemented. Biofilm sampling was conducted in Degurić and Vernjikica Cave located in Western and Eastern Serbia, respectively. Ecological parameters (temperature, relative humidity, light intensity) and distance from the entrance were measured. Additionally, chlorophyll content, as well as biofilm parameters (water content, organic and inorganic matter) were determined. The abundance of phototrophic microorganisms was assessed on microscope slides which contained 1 mg of biofilm that was dehydrated for a short period of time and homogenized prior to slide preparation, and then rehydratated. The biomass of recorded cyanobacterial and algal taxa was calculated by applying geometric approximations and standard mathematical formulas. In Degurić Cave, at the sampling site where the highest biomass was documented, the higher diversity, water content and chlorophyll values were also recorded, while in Vernjikica Cave a high content of organic matter was documented. According to the multivariate analyses performed, the biomass of simple trichal Cyanobacteria, Bacillariophyta, and Xanthophyta was positively correlated with the content of organic matter in biofilm and light intensity, while coccoid and heterocytous Cyanobacteria and Chlorophyta showed a positive correlation with water content in the biofilm, relative humidity and distance from the entrance. The total biomass was positively correlated with the chlorophyll content, organic matter and light intensity, and negatively with the distance from the entrance.

AB  - Most field charophytologists have experienced that the morphology of Chara specimen can be intermediate” between two different species. We collected a Chara sample in lake Sava, close to Belgrade, Serbia. The habitus of this specimen resembled C. contraria, but the microscopic details (“spines”, stipulodes) resembled C. virgata. Preliminary analysis of the matK gene, however, clearly place the sample into C. contraria. This means that C. contraria sometimes may have stipulodes where only the upper row is elongated. We also collected a sample which orphologically resembled C. connivens in Dulin pond (44°51’11.5” N 21°17’52.2” E), Serbia. The sample was clearly dioecious, and we analysed male and female samples. Preliminary analyses of the matK gene placed this sample into a separate sub-cluster of C. globularis (i.e. not together with C. connivens, but an own sub-group within C. globularis). We will present the most recent results on these specimens.

abstract = "Most field charophytologists have experienced that the morphology of Chara specimen can be intermediate” between two different species. We collected a Chara sample in lake Sava, close to Belgrade, Serbia. The habitus of this specimen resembled C. contraria, but the microscopic details (“spines”, stipulodes) resembled C. virgata. Preliminary analysis of the matK gene, however, clearly place the sample into C. contraria. This means that C. contraria sometimes may have stipulodes where only the upper row is elongated. We also collected a sample which orphologically resembled C. connivens in Dulin pond (44°51’11.5” N 21°17’52.2” E), Serbia. The sample was clearly dioecious, and we analysed male and female samples. Preliminary analyses of the matK gene placed this sample into a separate sub-cluster of C. globularis (i.e. not together with C. connivens, but an own sub-group within C. globularis). We will present the most recent results on these specimens.",

AB  - The aim of this study was to assess the effect of substrate type and incubation depth on periphyton that had developed on artificial substrates. Uniform rectangular tiles made out of artificial substrates: glass, ceramic, willow tree and yew tree, were fixed on a floating buoy and deployed at three different depths in a photic zone of the Sava Lake (Belgrade, Serbia). Non-taxonomic attributes in the developed biofilm were estimated week-by-week from the start of the experiment in July, until its end in September 2014. Through assessment of substrate type and depth of incubation effect we concluded that these parameters for the fact influence periphyton development and composition. Glass was preferred by autotrophic component over ceramic and wooden substrates. In general, substrate type effect was diminished by increasing incubation depth. When non-taxonomic parameters are to be used in biomonitoring studies, our results suggest that glass substrate and shallow layer of water column (up to 50 cm) for incubation should be preferred.

AB  - The summer phytoplankton community was studied across both vertical and temporal scales in relation to environmental factors in the shallowrecreational Sava Lake. The sampling was conducted weekly at four depths from mid-July until mid-September 2014, in order to detect short-term changes within the assemblages. Besides physical and chemical parameters, meteorological data was also included in the investigation, as that year was characterized with extreme rainfall, which caused serious flooding in the region. The community succession was characterized by a reverse in the cyanobacteria (Codon M) and chlorococcal green algae (Coda F and J). Statistical analyses (RDA) indicated that changes in the community composition and successional pattern could have been due to the mixing regime variations in the reservoir, most likely induced by weather disturbances, especially high precipitation and wind events. These events did not permit massive cyanobacterial development, although they most likely caused resuspension of dissolved phosphorus from the sediment. When observing functional groups, three groups could be distinguished by their response to the above-mentioned parameters: the first prefers high temperature and insolation(Lm, Y, Lo, Xph, W2andM), the second is correlated with precipitation and wind (Td, C, K, MP and X2), while the third group tolerates cloudiness (H1, F, N, X1, D, J and P).

AB  - Substrate specificity of the periphyton community is usually underestimated in both periphyton ecology and biomonitoring studies, thus different kinds of both natural and artificial substrates (of organic and inorganic origin) are employed. Periphyton colonization and successional trajectories are particularly debatable processes when different kinds of substrates are considered. In our field experiment, we deployed four kinds of artificial substrates (two inorganic ones - glass and ceramic, and two organic ones - willow and yew wooden tiles) for the development of periphyton in an urban reservoir referred to as Lake Savsko (Belgrade, Serbia). We comparatively investigated the structure, colonization process, diversity and successional trajectories of periphyton. We also assessed the relationship between the dynamics of algae growth forms (ecological groups) on different substrates and selected abiotic limnological factors. Our objective was to determine whether the type of substrate affects periphyton characteristics at various levels and whether an artificial substrate potentially affects the bioindication capacity of ecological groups. We concluded that all substrates behave similarly at the level of structure and colonization phases, but when considering diversity and successional trajectories, the substrate specificity was demonstrated. Our results suggest that communities developed on inert substrates (glass and ceramic) could provide more realistic insight into complex environmental changes.

AB  - The Đetinja River is located in western Serbia and it was dammed for creating an artificial Lake Vrutci. Epilithic samples were collected during 11 season (September, October and December 2014, March, April, May, June, July, August, September and October 2015) and were scraped from the stones by brush. Permanent slides were observed by Zeiss AxioImagerM.1 microscope with DIC optics and AxioVision 4.8 software. The relative abundance of diatoms were estimated by counting 400 valves of each taxa present at every permanent slide. The biological assessment of water quality was performed using diatom indices calculating by OMNIDIA 5.3 software.
Total of 113 diatom taxa have been recorded in the studied samples. Achnanthidum minutissimum was abundantly developing in mass and predominating over the other diatoms in almost all season. Next to A. minutissimum Amphora inariensis, A. pediculus, Cocconeis placentula var. lineata, Gomphonema olivaceum, Nitzsschia amphibia and N. fonticola were dominant or subdominant in the community. The results of a diatom indices analysis show the good to very good ecological status of the Đetinja River in the investigated period. Organic pollution was absence as opposed to anthropogenic eutrophication. In almost all season anthropogenic eutrophication was low except in March where anthropogenic eutrophication was moderate. In March Gomphonema olivaceum was dominant taxa in the community. G. olivaceum is β-mesosaprobous, eutraphentic species.
The Đetinja River was characterized by high species diversity and good to very good ecological status which matches with the literature data, rivers and streams with low level of pollution are characterized by high species richness.

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.
