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  - 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.

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  - 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.

abstract = "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.

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  - Epilithic diatoms are frequently recommended for river biomonitoring, while much less emphasis is placed on epiphytic communities.
This study considers use of epiphytic and epilithic diatom communities from the Raška River in biomonitoring. A total
of 212 diatom taxa were recorded in both communities. Dominant diatoms were Achnanthidium minutissimum (Kützing)
Czarnecki, A. affine (Grunow) Czarnecki, A. subatomus (Hustedt) Lange-Bertalot, Amphora pediculus (Kützing) Grunow,
Diatoma vulgaris Bory, Gomphonema tergestinum (Grunow) Fricke, Cocconeis placentula var. lineata (Ehrenberg) Van
Heurck, Melosira varians Agardh and Navicula tripunctata (Müller) Bory. Redundancy analysis (RDA) was used to detect
the relationships between diatoms, some environmental factors and sampling sites. Diatoms of the epiphytic community showed
a clearly grouping in relation to the sampling sites as compared with diatoms of the epilithic community. Species common to both
communities showed a similar correlation with some environmental variables (BOD, pH, NH4
+, TP, NO3
− and conductivity),
with three exceptions (Diatoma vulgaris, Cymbella compacta, and Encyonema silesiacum). Pearson’s correlation coefficient
showed correlation between selected environmental variables and diatom indices calculated usingOMNIDIA 6.2 software (TDI,
IPS, CEE, GENRE, TID, SID, SHE and IDSE/5). Diatoms of the epiphytic community are more clearly clustered in relation to
the sampling sites as compared with diatoms of the epilithic community. According to our results there is still Bplace^ in
biomonitoring for epiphytic community. The present study highlights the necessity of sampling both epiphytic and epilithic
communities because substrate specificity could play important role in biomonitoring.

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).

abstract = "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  - 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.
