AB  - Ponds, the most numerous freshwater habitats globally, are becoming increasingly recognized as being important for rare, endemic and endangered species, owing to the high levels of biodiversity they support and their role in ecosystem services. However, they remain largely overlooked and widely excluded from policies that might protect them. Even though their size and permanence are highly important for their legal protection, these two characteristics are not precisely and universally defined in theory and in international legal documents. International legislative frameworks do not seem to provide global, comprehensive, or detailed protection of ponds as significant and widespread habitats. On the contrary, they safeguard only fragmentary small water bodies – either by protecting certain types or only those that are parts of larger protected areas. Also, pondscapes are not specifically recognized as forms in need of legal protection. In this paper, the complexity of the legal protection of ponds is presented, followed by recommendations. These should be transformed into legal norms, and given their number and complexity be presented within a single, unique convention that would specifically address the protection of ponds globally. This type of protection would be the most effective legal tool.

AB  - In Serbia, almost all charophyte species belong to one of the IUCN categories. This study aimed to gather more knowledge about their floristic richness, distribution and ecology. During the survey, 262 localities were investigated in the Vojvodina province, northern Serbia. Seventeen charophyte species were found, out of which 16 were included in the analyses. The environmental matrix included 38 localities, each characterized by habitat type and 35 environmental parameters. The canonical correspondence analysis (CCA) showed six parameters as being statistically significant: substrate, altitude, depth, water temperature, temperature annual range and precipitation of the driest month. Together, these explain the 32.34% variability in the species composition and abundance data. Altitude and substrate contributed the most to this. Two main types of habitats were outlined by the analysis. Small and shallow temporary habitats in the river floodplains, at lower altitudes, with muddy and clayish substrate, belong to one type. These areas are inhabited by either very tolerant species, such as Chara vulgaris and C. globularis, or the so-called “spring” species of the genera Tolypella and Nitella. Habitats which are located at higher altitudes, when deeper and more permanent with a sandy substrate, such as sandpits and river habitats, belong to the second one. These areas are inhabited by species like Chara papillosa, C. hispida, and Nitellopsis obtusa.

AB  - Combining morphological and molecular approaches, a new diatom species is described in the genus Mayamaea from a Special Nature Reserve, Okanj bara in Serbia, an alkaline and subsaline soda pan with pronounced seasonal drying. Mayamaea pannonica sp. nov. possesses typical characteristics of the genus Mayamaea, such as uniseriate striae and hymenes that cover the areolae from the outside. It can easily be distinguished from similar species by the valve outline and shape of the central area.
Although presently no culture of the species is available, we identified in an amplicon data set from the
same sample a partial 18S rRNA gene sequence that is thought to represent the new species, with high
probability. A comparison of our sequence to those present in the Diat.barcode and NCBI databases
showed that the sequence is closely related to, but significantly different from, that of Mayamaea
terrestris. Natural saline habitats in Serbia and neighbouring countries are under anthropogenic threat
and climate change, so knowing which species live here is the first step in preserving these unique
habitats.

AB  - During a survey of diatoms in the artificial sandpit lake “Peskara” in the protected zone of the Rusanda Nature Park, a large number of brackish taxa at epipsamic and epiphytic communities were recorded (e.g. Bacillaria paxillifera, Caloneis permagna, Ctenophora pulchella, Entomoneis costata. Haslea duerrenbergiana, Navicula salinarum, Nitzschia agnita, N. filiformis, Staurophora brantii, Seminavis strigosa, Tryblionella apiculata). One new genus Seminavis and 15 diatom species were noted for the first time for the diatom flora of Serbia. Dominant taxa changed over seasons without any regularity. In spring 2021, we have observed an increased abundance of centric species Thalassiosira pseudonana and Stephanodiscus parvus while in other seasons it was difficult to discern a pattern of dominance among benthic diatoms. Metabarcoding analysis of the same sample using 18S rRNA as a gene marker confirmed the dominance of centric diatoms. This study contributes to a better understanding of brackish diatom taxa found in inland habitats, many of which can be utilized as useful tools for the ecological status assessment.

AB  - In this study we have reported the chemical composition of the essential oils obtained from the needles of twelve Pinus taxa, belonging to the subgenera Pinus (sections Pinus and Trifoliae) and Strobus (sect. Quinquefoliae). Monoterpenes dominated over sesquiterpenes in most of the investigated taxa of both subgenera, except in representatives of the subsection Pinaster, subgenus Pinus. α-Pinene was the most abundant terpene in eight pines, but other dominant terpenes were found in some taxa - trans-caryophyllene, germacrene D, abietadiene and β-pinene. In the subsect. Pinaster, the most dominant compounds varied from species to species. In addition, P. halepensis and P. pinaster had the highest percentage of diterpenes, while P. heldreichii was the richest in germacrene D. In the PCA and cluster analyses, three species from the subsect. Pinaster emerged as the most distant: P. halepensis, P. pinaster, and P. heldreichii. In addition, the possible taxonomic implications of the terpene profile in the analysed Pinus taxa were also discussed.

AB  - The mobility of chemical elements in the soil-orchid system has been poorly studied. The aim of this study is to evaluate the uptake and mobility of several trace (Li, Ba, Sr, Ag, Hg, and B) and macronutrients (Ca, Mg, and K) in the orchid Anacamptis morio (L.) R.M.Bateman, Pridgeon & M.W.Chase from soils in western Serbia. The sampling sites are characterized by three different bedrock types—cherts, limestones, and serpentines, which are the source of the significant chemical differences in the elemental status of the soil and plant tissues. The four-step Community Bureau of Reference sequential extraction procedure was used to determine the distribution of fractions and predict their potential phytoavailability. The orchid and soil samples were analyzed for total elemental content analysis using ICP-OES. The greatest potential for plant availability was determined for Ba and Sr, representing about 80% of the total soil content. More than 40% of Li in the soils was found to be potentially phytoavailable. Significant correlations were found between the total content of Li, B, and Sr in soils. Between 38 and 60% of Li content and more than 80% of Ba and Sr content were determined to be potentially phytoavailable by sequential analysis. The highest bioconcentration factor (> 1) was determined in the case of B and Sr for all orchid organs, while translocation factor for Li was highest in tubers and leaves. The studied elements were mainly stored in tubers and roots, indicating the exclusion strategy of A. morio as a metal tolerance mechanism. The data obtained showed significant differences in metal content in soils and plants originating from sites with different parent materials, suggesting that bedrock type and associated soil properties are important factors that determine chemical element mobility and uptake.

AB  - Hydrogels are promising materials for biomedical applications due to highly hydrated, porous, permeable structure with possibility to accommodate living cells, drugs, or bioactive factors. In this paper, we reported poly(methacrylic acid) (PMAA)/gelatin IPN hydrogels, synthesized by free-radical polymerization, with adjustable mechanical, structural, physicochemical, and biological characteristics. The influence of methacrylic acid (MAA), gelatin, and cross-linker in the precursor solution on hydrogels properties was investigated. The increasing concentration of MAA, gelatin, and cross-linker led to better mechanical properties, lower porosity, and water content. The compressive mechanical properties of hydrogels were significantly better in comparison to a single-network PMAA hydrogel, while the obtained compressive strength values up to 16 MPa were comparable with tough hydrogels. The increasing concentration of MAA and cross-linker reduced fatigue resistance and degradability, while the increase in gelatin content acted in the opposite way. Swelling tests in different pH conditions demonstrated strong pH-sensibility of the hydrogels, which was more pronounced as MAA concentration was higher, and gelatin and cross-linker concentrations were lower. In addition, the hydrogels strongly promoted the proliferation of human periodontal ligament stem cells and MRC-5 cells as assayed by MTT assay.

AB  - Aims Because the Staphylococcus aureus is one of the most well‐known pathogens associated with medical devices and nosocomial infections, the aim of the study was to examine antibiofilm potential of emodin against it.  Methods and Results Antibacterial activity was examined through microdilution assay. Antibiofilm testing included crystal violet staining of biofilm biomass and morphology analysis by Atomic force microscopy (AFM). Furthermore, aerobic respiration was monitored using the Micro‐Oxymax respirometer. For investigation of gene expression qRT‐PCR was performed. Emodin demonstrated strong antibacterial activity and ability to inhibit biofilm formation of all tested strains. The effect on preformed biofilms was spotted in few strains. AFM revealed that emodin affects biofilm structure and roughness. Monitoring of respiration under emodin treatment in planktonic and biofilm form revealed that emodin influenced aerobic respiration. Moreover, qRT‐PCR showed that emodin modulates expression of icaA, icaD, srrA and srrB genes, as well as RNAIII, and that this activity was strain‐specific.  Conclusion The results obtained in this study indicate the novel antibiofilm activity of emodin and its multiple pathways of action.  Significance and Impact of Study This is the first study that examined pathways through which emodin expressed its antibiofilm activity

AB  - Biological activity of 2-tert-butyl-1,4-benzoquinone (TBQ) and its derivatives, 2-tert-butyl-5-(2-propylthio)-1,4-benzoquinone, 2-tert-butyl-5- -(propylthio)-1,4-benzoquinone, 2-tert-butyl-5,6-(ethylenedithio)-1,4-benzoquinone, 2-tert-butyl-5-(phenylthio)-1,4-benzoquinone and 2-tert-butyl-6-(phenylthio)- 1,4-benzoquinone, were tested for their antioxidant, antibacterial, toxic, cytotoxic and genotoxic potential. Using the DPPH test, all derivatives showed good antioxidant activity, better than ascorbic acid, and the 2-tert- -butyl-5-(propylthio)-1,4-benzoquinone derivative showed the strongest effect. Better antibacterial potential was observed against Gram-positive bacteria in the broth microdilution method in which the 2-tert-butyl-5-(phenylthio)-1,4- -benzoquinone derivative showed the strongest activity (MIC = 15.6 μM). The results of toxicity tests, using the Brine shrimp test, indicated that the derivatives lose their toxic potential compared to TBQ, except for 2-tert-butyl-6- -(phenylthio)-1,4-benzoquinone, which showed a 3 times stronger effect. Cytotoxicity was assessed by the MTT assay in 24 and 72 h treatments in MRC-5, HS 294T and A549 cell lines in threefold decreasing gradient (11, 33 and 100 μM). Modifications potentiate the cytotoxic effect, and the strongest effect was observed with the 2-tert-butyl-5,6-(ethylendithio)-1,4-benzoquinone derivative. In addition, the genotoxic potential was examined in the MRC-5 cell line using the comet assay. All tested derivatives of TBQ showed a genotoxic effect at all applied subtoxic concentrations. In general, the chemical modifications of TBQ enhanced its biological activity.

Применом DPPH теста, сви деривати су показали добру антиоксидативну активност, бољу од аскорбинске киселине, а најјаче дејство показао је дериват 2-терц-бутил-5-(пропилтио)-1,4-бензохинон. Бољи антимикробни потенцијал је примећен против Грам-позитивних бактерија методом микродилуције у бујону, где је дериват 2-терц-бутил-5-(фенилтио)-1,4-бензохинон показао најјачу активност (MIC = 15,6  μМ). Резултати испитивања токсичности, применом теста на Artemia salina, показују да деривати губе токсични потенцијал у односу на TBQ, осим 2-терц-бутил-6-(фенилтио)-  -1,4-бензохинона, који је показао 3 пута јачи ефекат.

AB  - In the present study, a new species, Nitzschia haloserbica Vidaković, Ector, C.E.Wetzel & Krizmanić, sp. nov., is described from alkaline saline ponds and channels from Vojvodina Province (Serbia). In 2019 the new species was found in four saline ponds: Bela Bara, Čoka Kopovo, Velika Rusanda and Slatina. The same species was recorded four years ago in saline lakes in Hungary, but the authors listed it as Nitzschia sp. 2. The sigmoid valve outline of the new Nitzschia Hassall species is similar to N. austriaca Hust. but differs in striae density and fibulae distribution. In N. haloserbica sp. nov. the transapical striae are so dense that they are not visible in light microscopy. Both species have fibulae that are quite regularly distributed along the raphe canal, but in N. austriaca the central two fibulae are more widely spaced, reflecting the presence of central raphe endings, which are absent in N. haloserbica sp. nov. At the type locality (Bela Bara) both species were found with relative abundances of 94.93 % for N. haloserbica sp. nov. and 1.21 % for N. austriaca (of the 400 valves counting per slide). The valve morphology, ultrastructure and autecology of the new species are discussed and compared with morphologically similar taxa.

Chez N. haloserbica sp. nov., les stries transapicales sont si denses qu’elles ne sont pas visibles en microscopie optique. Les deux espèces ont des fibules 
assez régulièrement réparties le long du canal du raphé, mais chez N. austriaca les fibules centrales sont plus espacées, reflétant la présence de terminaisons centrales du raphé, qui sont absentes chez N. haloserbica sp. nov.

Chez N. haloserbica sp. nov., les stries transapicales sont si denses qu’elles ne sont pas visibles en microscopie optique. Les deux espèces ont des fibules 
assez régulièrement réparties le long du canal du raphé, mais chez N. austriaca les fibules centrales sont plus espacées, reflétant la présence de terminaisons centrales du raphé, qui sont absentes chez N. haloserbica sp. nov. Dans la localité type (Bela Bara), nous avons trouvé les deux espèces avec des abondances relatives de 94,93% pour N. haloserbica sp. nov. et de 1,21% pour N. austriaca (estimation à partir des 400 valves comptées par lame). La morphologie de la valve, l’ultrastructure et l’autécologie de la nouvelle espèce sont discutées et comparées à des taxons morphologiquement apparentés.",

AB  - In order to improve the performance of theoretical UV–Vis spectra predictions, a theoretical and experimental study of solvatochromic properties of ten azo pyridone dyes has been performed. For quantitative estimation of intermolecular solvent–solute interactions, a concept of the linear solvation energy relationships has been applied using Kamlet-Taft and Catalán models. Theoretical UV–Vis spectra for all dyes have been calculated using four TD-DFT methods in nine different solvents with the aim to define the most reliable model. Finally, new polylinear equations for more accurate theoretical prediction of UV–Vis maxima are developed using empirical Kamlet-Taft and Catalán solvent parameters as additive corrections for specific and nonspecific solvent–solute interactions.

AB  - Introduction
Ramonda serbica and R. nathaliae are resurrection plants that have the remarkable ability to survive the complete desiccation of their vegetative organs (i.e. leaves, stem, roots) during periods of drought and rapidly revive when rewatered and rehydrated.

Objective
To investigate metabolic changes in R. serbica and R. nathaliae during their desiccation and recovery process

Methods
Proton nuclear magnetic resonance (1H-NMR) and gas chromatography–mass spectrometry (GC–MS)-based metabolomics approach coupled with multivariate data analysis was utilised to identify the metabolomes of the plants from 90 biological replicates.

Results
Sucrose and the polyphenolic glycoside myconoside were predominant in almost equal amounts in all samples studied, regardless of their water content at sampling. During the dehydration process, a decrease in the relative content of fructose, galactose, and galactinol was observed while the contents of those metabolites were preserved in the partially rehydrated plants. Raffinose and myo-inositol were accumulated in dry samples.

Conclusion
Using 1H-NMR and GC–MS as two complementary analytical platforms provided a more complete picture of the metabolite composition for investigation of the desiccation and recovery process in resurrection plants.

performed, which resulted in eight principal components (PCs) in both models,
explaining 77.0% of the total data variance in the model with R. serbica samples,
and 79.5% of the variance in the model with R. nathaliae samples. Using NMR
experiments, the content of the two most dominant polar components found in the
leaves of these two plants was determined. Sucrose and the polyphenolic glycoside
myconoside were predominant in almost equal amounts in all samples studied,
regardless of their water content at sampling. Using of 1D and 2D NMR
experiments the main components have been successfully identified. Also, it was
necessary to isolate and purify the myconoside to confirm the structure.

AB  - Thirteen undescribed 24-methylene lanostane triterpenoids, named polyporenic acids E-M and fomitosides L-O, as well as seventeen known analogues, were isolated from the fruiting bodies of the mushroom Fomitopsis betulina. Their structures were determined using 1D, 2D NMR, IR, and HRESIMS. Fomitoside L and fomitoside N exhibited cytotoxicity against HL60 leukemia cells (IC50 = 15.8 and 23.7 μM, respectively). Among the known compounds, notable cytotoxicities against HL60 leukemia cells and selectivity with respect to MRC-5 healthy cells were noticed for dehydropachymic acid (IC50 = 10.9 μM, SI 8.6), pachymic acid (IC50 = 11.0 μM, SI 9.8), 3-epi-dehydrotumulosic acid (IC50 = 19.9 μM, SI 5.8) and 12α-hydroxy-3α-(3′-hydroxy-4′-methoxycarbonyl-3′-methylbutyryloxy)-24-methyllanosta-8,24 (31)-dien-26-oic acid (IC50 = 19.2 μM, SI 2.2).

AB  - Eleven 31-methylenlanostane triterpenoids, i.e., seven 21- and four 26-oic acids, as well as a lupane triterpenoid betulin, isolated from the fruiting bodies of the mushroom Fomitopsis betulina, were tested for in vitro protective effect on chromosome aberrations in peripheral human lymphocytes using cytochalasin-B blocked micronucleus (CBMN) assay. Most of the tested compounds showed a beneficial effect by reducing DNA damage of human lymphocytes more effectively than amifostine, a radioprotective agent, used as a positive control. All the tested compounds decreased MN frequency in the concentration dependent manner, with the concentration of 2.0 µg mL-1 being the most effective – with increase of the concentration the activity slightly decreases. The structure–activity relationship (SAR) studies indicated that the lanostanes containing a conjugated 7,9 (11)-diene system exhibit lower activity than Δ8-analogues. It was also demonstrated that the DNA protective activities within the Δ8-lanostane-26-oic acid group are affected by the substitution in position 3 pattern. In the Δ8 series the oxygenation at C-12 or 16 as well as 21- or 26-oic acid functionality proved beneficial for in vitro protective effect on chromosomal aberrations. Betulin exhibited the lowest protective activity, but it is still comparable to that of amifostine.

агенс аминофостин. У опсегу концентрација 1, 2 и 4 μg mL-1 сва испитивана једињења су
смањивала учесталост микронуклеуса (MN), при чему је најефиканија била концентра-
ција од 2,0 μg mL-1. Са повећањем концентрације (4 μg mL-1) активност се благо смањује.
Студије односа структуре и активности (SAR) показале су да ланостани који садрже кон-
југовани 7,9-(11)-диенски систем имају нижу активност од _8-аналога. Такође је пока-
зано да на заштитне активности ДНК унутар групе _8-ланостан-26-киселина утиче суп-
ституција у положају 3. У _8-серији присуство кисеоничних функција на C-12 или C-16,
као и C-21 или C-26 карбоксилних група повећава in vitro протективни ефекат на на
ДНК хуманих лимфоцита. Међу испитиваним једињењима тритерпен бетулин (лупанска

AB  - Duckweed (L. minor) is a cosmopolitan aquatic plant of simplified morphology and rapid vegetative reproduction. In this study, an H. paralvei bacterial strain and its influence on the antioxida-tive response of the duckweeds to phenol, a recalcitrant environmental pollutant, were investigated. Sterile duckweed cultures were inoculated with H. paralvei in vitro and cultivated in the presence or absence of phenol (500 mg L−1 ), in order to investigate bacterial effects on plant oxidative stress during 5 days. Total soluble proteins, guaiacol peroxidase expression, concentration of hydrogen peroxide and malondialdehyde as well as the total ascorbic acid of the plants were monitored. Moreover, bacterial production of indole-3-acetic acid (IAA) was measured in order to investigate H. paralvei’s influence on plant growth. In general, the addition of phenol elevated all biochemical parameters in L. minor except AsA and total soluble proteins. Phenol as well as bacteria influenced the expression of guaiacol peroxidase. Different isoforms were associated with phenol compared to isoforms expressed in phenol-free medium. Considering that duckweeds showed increased antioxidative parameters in the presence of phenol, it can be assumed that the measured parameters might be involved in the plant’s defense system. H. paralvei is an IAA producer and its presence in the rhizosphere of duckweeds decreased the oxidative stress of the plants, which can be taken as evidence that this bacterial strain acts protectively on the plants during phenol exposure.

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  - 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  - 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  - Lampenflora communities of bacteria, cyanobacteria, algae, mosses and lichens colonize illuminated show-caves as a consequence of disturbances to the caves’ ecological equilibrium. These communities have unesthetic impacts and can cause the biodeterioration of limestone. A 15% hydrogen peroxide solution was proposed for use as an ecological agent for the safe removal of these microorganisms. This study tested the effects of three different biocides (hydrogen peroxide, a commercial solution containing salicylic acid and a product containing chlorine dioxide as the active component), on the growth of green algae (Chlorella sp.), which are frequently encountered in lampenflora communities. Chlorella sp. was treated with the biocides under laboratory condition, and chlorophyll a (Chl a) concentrations were measured 1 h, 3 days, 7 days and 10 days after treatment. The change in Chl a concentration was compared to the untreated control group at each time point. All three biocides prevented the growth of green algae and the product containing chlorine dioxide appeared to be the most effective growth inhibitor. Hydrogen peroxide is known to suppress lampenflora growth in caves, and further studies on other biocides remain necessary to identify a solution that is both ecologically safe and economically feasible.

AB  - The synthesis of novel triphenyltin(IV) compounds, Ph3SnLn (n = 1–3), with oxaprozin (3-(4,5-diphenyloxazol-2-yl)propanoic acid), HL1, and the new propanoic acid derivatives 3-(4,5bis(4-methoxylphenyl)oxazol-2-yl)propanoic acid, HL2, and 3-(2,5-dioxo-4,4-diphenylimidazolidin1-yl)propanoic acid, HL3, has been performed. The ligands represent commercial drugs or their derivatives and the tin complexes have been characterized by standard analytical methods. The in vitro antiproliferative activity of both ligands and organotin(IV) compounds has been evaluated on the following tumour cell lines: human prostate cancer (PC-3), human colorectal adenocarcinoma (HT29), breast cancer (MCF-7), and hepatocellular cancer (HepG2), as well as on normal mouse embryonic fibroblast cells (NIH3T3) with the aid of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-12 diphenyltetrazolium bromide) and CV (crystal violet) assays. Contrary to the inactive ligand precursors, all organotin(IV) carboxylates showed very good activity with IC50 values ranging from 0.100 to 0.758 µM. According to the CV assay (IC50 = 0.218 ± 0.025 µM), complex Ph3SnL1 demonstrated the highest cytotoxicity against the caspase 3 deficient MCF-7 cell line. Inductively coupled plasma mass spectrometry (ICP-MS) analysis indicated a two-fold lower concentration of tin in MCF-7 cells in comparison to platinum. To investigate the mechanism of action of the compound Ph3SnL1 on MCF-7 cells, morphological, autophagy and cell cycle analysis, as well as the activation of caspase and ROS/RNS and NO production, has been performed. Results suggest that Ph3SnL1 induces caspase-independent apoptosis in MCF-7 cells.

AB  - Alkaline saline ponds and lakes are habitats with unique biodiversity. The green alga of the genus Botryococcus was accidentally discovered during a micro-algal survey of these habitats in Serbia. Species B. terribilis was found and identified for the first time in Serbia in the small sandpit lake of the Rusanda Nature Park. The first sampling was incomplete due to the unknown origin of the orange-red surface scum. After the identity of the species had been confirmed, three additional samplings were conducted aiming to collect phytoplankton and water samples for physical and chemical analyses. Major anions and cations were analysed in order to characterize the chemical type of sandpit lake, as well as nutrient content. Sandpit lake is an alkaline water body that belongs to sodium bicarbonate chemical type. Morphometric analysis of B. terribilis was performed using light and transmission electron microscopy. B. terribilis was found to be numerous in the phytoplankton community in late autumn and winter. Species from the genus Botryococcus are known as a rich source of different lipids and this discovery can be the first step in the further biotechnological application of this species in sustainable biofuel production.

AB  - Soda pans are protected in the European
Union as Natura 2000 areas in the category of
‘‘Pannonic saline steppes and marshes’’. There are at
least six soda pans of reference status in Serbia and
only a half have strict legal protection. The number of
similar, but disturbed (modified) habitats that could be
reconstructed is still unknown. We conducted sampling
in five natural and two disturbed soda pans
aiming to compare a difference in physical and
chemical water properties and benthic diatom communities.
In addition, we tried to apply recently
developed Diatom Index for Soda Pans (DISP) and
Trait-based index (TBI) to test the applicability of
taxonomic and trait-based approaches in ecological
status assessment of soda pans in the southern part of the Carpathian Basin. In contrast to natural soda pans,
lower pH and nutrients levels were recorded in
disturbed pans. A total of 86 taxa of benthic diatoms,
including 11 new for diatom flora of Serbia, were
identified. A lower species richness and Shannon
index was recorded in natural soda pans. Nitzschia
austriaca, N. supralitorea, Navicula veneta and N.
wiesneri were dominant diatoms in soda pans of the
reference status. Both diatom indices were in average
lower in disturbed pans, and this difference was
statistically significant for DISP index. We concluded
that two indices, supplemented with indicator values
for some local diatom species, can be a promising tool
for soda pan conservation in this part of the Carpathian
Basin.
