AB  - The black bullhead is an invasive species that forms dense populations and has a negative impact on the native ichthyofauna. Recent studies indicate that it is one of the most dominant invasive fish species in Serbian waters. Feeding habits based on stomach contents of individuals caught in Lake Sava were analyzed as a first step towards evaluating its possible negative impact on the native fish fauna of the lake. The following indices for diet analysis were applied: vacuity index, frequency of occurrence, numerical abundance and prominence value. Trophic niche breadth and seasonal trophic diversity were calculated using the Shannon's index. The diet spectrum comprised 16 different prey categories from five groups: Mollusca, Crustacea, Insecta, Teleostei and plants. Fish were the main prey in all seasons, followed by aquatic invertebrates. Plant material and terrestrial insects were used as food in relatively small quantities. Predation on fish eggs was also detected. Our research confirmed that this species is an opportunistic generalist. An ontogenetic diet shift was also detected. The lowest value of trophic diversity was found in age 1+ individuals (H=1.39), while the highest was found in age 3+ individuals (H=2.00). The widest niche breadth was recorded in spring 2011 (H=2.12).

AB  - Gobioids (Gobiiformes: Gobioidei) are a large group of vocal fishes with four sound types documented during aggressive or reproductive interactions in 23 species. Most attention has been dedicated to sound production in Gobiidae and Gobionellidae, while acoustic communications in other phylogenetically distant gobioid groups have been neglected. Odontobutidae, a basal family within the gobioids, is a poorly studied fish assemblage, with sounds documented in only a single species. The goal of this study was to record and describe the acoustic signals produced by Perccottus glenii (Odontobutidae) under laboratory conditions, with particular focus on the reproductive phase (courtship and pre-spawning), and to provide insight into the anatomical basis of the sound emission mechanism. We recorded two acoustically different call types, thumps and tonal sounds. Thumps were low-frequency sounds (similar to 95 Hz) with an irregular waveform, produced by males during both the courtship and pre-spawning phases. Thumps were frequently organized in long trains, a thump burst, composed from approximately five thumps and lasting over 10 s. Tonal sounds were short vocalizations (similar to 90 ms) produced only during courtship interactions, characterized by a sinusoidal oscillogram and a single frequency peak (similar to 120 Hz). Additionally, anatomical examination focusing on the pectoral girdle identified the muscles that could be responsible for sound emission. The levator pectoralis muscle, originating on the neurocranium and attaching to the cleithral bone, is separated into three bundles: a pars lateralis superficialis, a pars lateralis profundus and a pars medialis. These results expand the knowledge about gobioid vocal behaviour and underline the importance of acoustic communication within this group of fish. Odontobutidae is a sister group to rest of the gobioids, and therefore, our results have significant impact for future comparative studies dealing with sound production.

AB  - Istraživanje je sprovedeno tokom leta 2017. godine na šest veštačkih jezera u Srbiji izgrađenih sa različitom namenom – vodosnabdevanje (Garaši), proizvodnja električne energije (Vlasina, Perućac, Zaovine i Međuvršje) i rekreacija (Savsko jezero), različitih karakteristika i stupnjeva eutrofikacije. Analiza Ag, Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Se, Si, Sr i Zn u mišiću, škrgama i jetri grgeča, kao i u uzorcima vode i sedimenta, izvršena je optičkom emisionom spektroskopijom sa induktivno spregnutom plazmom (ICP-OES). Histopatološke (HP) analize škrga i jetre i Fultonov faktor kondicije (CF) upotrebljeni su kao biomarkeri. Ispitana je korelacija između CF i koncentracije elemenata u tkivima, kao i između HP indeksa škrga i jetre. Takođe, izračunate su vrednosti indeksa opterećenja zagađenjem (PLI), stepena kontaminacije (Cd), potencijalnog ekološkog rizika (RI) i rizika po zdravlje ljudi (THQ i TR). Akumulacija elemenata varirala je značajno između tkiva, kao i između ispitivanih veštačkih jezera. Škrge su bile najviše zahvaćene zagađenjem. Zabeležen je nizak nivo HP promena, bez značajnih razlika između ispitivanih jezera. Nisu pronađene značajne korelacije između CF i koncentracije elemenata u tkivima, kao i između HP indeksa. Prema vrednosti PLI, sediment svih ispitivanih jezera bio je kontaminiran, ali su niske vrednosti zabeležene za Cd i RI. Veštačka jezera za proizvodnju električne energije imala su veće vrednosti PLI, Cd, RI, i TR. THQ i TR bili su veći za ribare u poređenju sa opštom populacijom. Rezultati su ukazali na to da su veštačka jezera za proizvodnju električne energije pod najvećim antropogenim pritiskom i/ili imaju lošiju politiku upravljanja zagađenjem u poređenju sa ostalim tipovima veštačkih jezera.
AB  - This study was conducted during the summer of 2017 in six reservoirs in Serbia used for different purposes – water supply (Garaši), electricity generation (Vlasina, Perućac, Zaovine and Medjuvršje) and recreation (Lake Sava), with different characteristics and degrees of eutrophication . Analysis of Ag, Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Se, Si, Sr, and Zn in muscle, gills and liver of the European perch, as well as in water and sediment samples, was performed by inductively-coupled plasma optical emission spectroscopy (ICP-OES). Histopathological (HP) analysis of gills and liver and Fulton's condition factor (CF) were used as biomarkers. The correlations between the elemental accumulation and CF, as well as between HP indices for gills and liver were assessed. Also, the values of pollution load index (PLI), degree of contamination (Cd), potential environmental risk (RI), and human health risk (THQ and TR) were assessed. Elemental accumulation varied considerably both among tissues and reservoirs. The gills were most affected by pollution. Low levels of HP changes were observed, with no significant differences between the reservoirs. No significant correlations between the elemental accumulation and CF, as well as between HP indices were observed. The PLI indicated that sediments in all six reservoirs were contaminated, but Cd and RI were low. Higher values of PLI, Cd, RI, and TR were observed in electricity generation reservoirs. Results indicated that this type of reservoirs suffer from higher anthropogenic pressure and/or have a worse pollution management policy compared with other types of reservoirs included in this study, especially the drinking water supply reservoir.

AB  - Proteins and phenols are minor, but important components of honey. Phenols originate from nectar and proteins from nectar/pollen and bees themselves. These two types of compounds are important for growth and development of bee colonies, and also for their defense capacity. Their quantity in honey depends on food accessibility and forage during the year. In this preliminary study, we aimed to see yearly dynamics of ratio of phenols and proteins in honey for a bee colony, and to observe the possible effects of extended oxalic acid antivarroa treatment on honey composition regarding proteins and phenols. Since proteins and phenols are fluorescently active, for measurement of phenol/protein ratio in honey we applied steady-state fluorescence spectroscopy as a rapid and non-destructive method. We determined the ratio of the spectral components related to these two main fluorophores in honey, proteins and phenolic compounds, as a ratiometric indicator of variability in honey samples collected in different seasons. We found that oxalic acid does not influence proteins' and phenolics' composition of honey, based on the spectral analysis. Since proteins in honey originate mainly from bees colony, this result indicates that oxalic acid did not change bee synthesis of proteins, indicating that oxalic acid, as a protective agent, is not harmful to the bees.

AB  - This study was conducted on individuals of European perch from six reservoirs in Serbia with different properties, used for different purposes, and situated at different altitudes. Samples of muscle, gills, and liver, as well as water samples, were used for analysis of elemental accumulation.

Analysis of Ag, Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Se, Si, Sr, and Zn was conducted by inductively-coupled plasma optical emission spectrometry (ICP-OES), and accordingly, metal pollution index and bioaccumulation factor (BAF) were calculated. Elemental accumulation varied considerably both among tissues and reservoirs. Reservoirs located on large low-altitude rivers were the most heavily polluted with metals (Meduvrgje, on the Zapadna Morava River, and Lake Sava, on the Sava River). Of three tissues analyzed, the gills were most affected by pollution. The levels of Hg in muscle decreased with an increase in reservoir altitude. Specimens sampled from the highest altitude reservoir were the least affected by HP alterations; however, HP differences between the reservoirs were not statistically significant, and the severity of HP changes was generally low. No significant correlations between the elemental accumulation or HP indices with CF were observed.

AB  - Fish erythrocytes released from erythropoietic sites are immature. During circulation, they increase their own surface, while the cell body and nuclei begin to become more elliptical and less spherical during maturation. The relative abundance of different developmental stages represents an erythron profile which could be a more sensitive indicator of contamination than classic hematological indices. In this study, we analyzed blood smears of the common nase (Chondrostoma nasus) and vimba bream (Vimba vimba) with the main goal to identify the determinants of the developmental stage of erythrocytes. Based on parameters developmental stages, erythrocytes are categorized into immature, intermediate or mature. In this investigation we have used four classification methods: the Two Step Cluster analysis, the K-Means Cluster analysis, and Neural Networks-Multilayer Perceptron and an Ordinal Regression model. Our findings clearly justify that Multilayers Perceptron and OLR models are appropriate to classify the developmental stage of fish erythrocytes in both species.

AB  - Many species are poorly known, with the sum of our knowledge represented by specimens in museums. For assessment of conservation status the most enigmatic and challenging species are probably those known only from a single specimen. We examine the potential persistence of such species using the orchid flora of Madagascar as a case study. We apply a statistical method that tests the likelihood of species presence in relation to the time when a species was collected and a measure of annual collection effort, calculated in three ways based on specimen collection over time. The results suggest that as of 2000 up to nine of the 236 orchid species known from a single specimen may be inferred to be extinct under at least one of the three methods of estimating collection effort and extinction. In addition, up to two additional species are likely to be extinct by 2018 assuming no new collections were made by that time. Substantial collection effort and/or additional evidence will be needed to reach a decision on the persistence of more recently observed species known only from a single collection. This represents a challenge for conservation practitioners.

AB  - Aims: Electroencephalography (EEG) measures could be a potential markers for prediction of repetitive transcranial magnetic stimulation (rTMS) outcomes in depression. The aim of this study was to investigate the value of alpha asymmetric index (AAI) in predicting treatment response in two different protocols of rTMS in patients with intractable major depression. 
Methods: Patients with intractable major depression (n=34) were divided into two treatment groups underwent two different rTMS protocols. The first group  received ten sessions 20 Hz rTMS  The second group received 10 Hz rTMS . The EEGs were recorded in all subjects pre- and post-intervention using a 19-channel, 10-20 electrodes placement protocol. Hamilton depression rating scale-17 items (HDRS-17) was used to divide the patients into responders and non-responder. The AAI in prefrontal (Fp1-Fp2), frontal (F3-F4 and F7-F8), and temporal (T3-T4) regions were calculated and compared between pre- and post-intervention in each group and between the responder and non-responder groups.
Results: In the 20 Hz rTMS group responders, 6 patients responded to the treatment, whereas 10 Hz rTMS showed 8 responders. In the responders of 20 Hz rTMS, the AAI at Fp1-Fp2, F3-F4, and T3-T4significantly decreased after the intervention (P=0.011, P=0.042, and P=0.035). The responders of 10 Hz rTMS showed significant reduction in the AAI at Fp1-Fp2 and T3-T4 regions after intervention (P= 0.023 and P=0.044). 
Conclusions: It seems AAI at prefrontal and temporal region scould be used for prediction of treatment response, regardless of rTMS protocol.

AB  - The aim of this study was to describe biometric and feeding characteristics of highly in-vasive species Perccottus glenii in the investigated locality. A total of 85 fish were elec-trofished in the drainage channel located at the vicinity of Veliko Gradište (northeastern Serbia) and preserved in the alcohol solution. In the laboratory, fish were measured (TL, ± 0.01 mm; W, ± 0.01 g), otholits and digestive tracts were removed for age determination and dietary analysis (stereomicroscope). Biometric analysis included length-frequency distribution using 10 mm class intervals; determination of average length and weight for each age group; lenght-weigth relationship; Fulton’s condition factor. Ingested organisms were identified to the lowest reliable taxonomic level (mainly order) and counted. The respective ranges of TL and W of examined fish were 35-140.7 mm and 0.5-40 g. Length class 70.1-80.0 mm clearly dominated (24%). Four age groups were determined (0+-3+), and their descriptive statistics is presented. The value of allometric coefficient for the length-weight relationship (b= 3.068) indicated isometric growth. Fulton’s condition fac-tor did not differ between age groups. Empty digestive tract was found in 2 specimens. A total of 12 prey categories representing Ephemeroptera, Trichoptera, Odonata, Hemiptera, Chironomidae, Coleoptera, Gastropoda, Hirudinea, Oligochaeta, Gammaraidae, uniden-tified and terrestrial insects were identified in the diet. Generally, the diet is entirely com-posed of aquatic invertebrates, as only one terrestrial insect was found. Obtained results did not show clear difference in diet composition between age groups. However, analysis have shown that the most diverse diet characterize 2+ age. By frequency, the insect larvae were categories with highest participation regardless of age.

AB  - Background and Aims: Neurofeedback treatment (NFT) may enhance attention performance in healthy individuals. This study investigated the effects of single session NFT on attention in healthy individuals performing a visual attention task. 
Methods: This was an open-label single-blinded trial conducted on 14 healthy university students (n=14; mean=23.35±0.58 years) of a major medical university in Iran. The subjects underwent a single session NFT while performing attentional network task (ANT). The NFT protocol was theta suppression/beta-1enhancement applied at Cz for 20 min. Before and immediately after NFT, EEG signals were recorded in subjects while performing ANT. EEGs were recorded using a 19 channel device and 10-20 placement protocol.
Results: The single session NFT increased the theta/beta-1 ratio in most of the electrode sites and the increase was statistically significant compared to the pre-intervention in the T6 site (p=0.011). The ratio decreased in just three sites of C3, Fz, and Cz, of them Fz showed a significant reduction (p=0.026). Contrary, the theta/alpha ratio decreased in most of the electrodes where the reductions were statistically significant in P3, P4, Cz, Pz (p<0.05), and C3 (p<0.01). The F7, F8, T3, and T4 showed no significant increased theta/alpha ratio. The central, temporal and occipital regions were involved in the NFT induced changes. Single NFT did not significantly change alerting, executive, or orienting networks of ANT.
Conclusions: Theta/beta-1 and theta/alpha ratios can be reliably used to assess NFT induced attention enhancement. However, single NFT did not induce clinical outcomes and repeated sessions seem necessary to modulate alerting, executive, or orienting networks of ANT.

AB  - Reports about the influence of cerium-oxide nanoparticles (nCeO(2)) on plants are contradictory due to their positive and negative effects on plants. Surface modification may affect the interaction of nCeO(2) with the environment, and hence its availability to plants. In this study, the uncoated and glucose-, levan-, and pullulan-coated nCeO(2) were synthesized and characterized. The aim was to determine whether nontoxic carbohydrates alter the effect of nCeO(2) on the seed germination, plant growth, and metabolism of wheat and pea. We applied 200 mgL(-1) of nCeO(2) on plants during germination (Ger treatment) or three week-growth (Gro treatment) in hydroponics. The plant response to nCeO(2) was studied by measuring changes in Ce concentration, total antioxidative activity (TAA), total phenolic content (TPC), and phenolic profile. Our results generally revealed higher Ce concentration in plants after the treatment with coated nanoparticles compared to uncoated ones. Considering all obtained results, Ger treatment had a stronger impact on the later stages of plant development than Gro treatment. The Ger treatment had a stronger impact on TPC and plant elongation, whereas Gro treatment affected more TAA and phenolic profile. Among nanoparticles, levan-coated nCeO(2) had the strongest and positive impact on tested plants. Wheat showed higher sensitivity to all treatments.

In this study, the uncoated and glucose-, levan-, and pullulan-coated nCeO(2) were synthesized and characterized. The aim was to determine whether nontoxic carbohydrates alter the effect of nCeO(2) on the seed germination, plant growth, and metabolism of wheat and pea. We applied 200 mgL(-1) of nCeO(2) on plants during germination (Ger treatment) or three week-growth (Gro treatment) in hydroponics. The plant response to nCeO(2) was studied by measuring changes in Ce concentration, total antioxidative activity (TAA), total phenolic content (TPC), and phenolic profile. Our results generally revealed higher Ce concentration in plants after the treatment with coated nanoparticles compared to uncoated ones. Considering all obtained results, Ger treatment had a stronger impact on the later stages of plant development than Gro treatment. The Ger treatment had a stronger impact on TPC and plant elongation, whereas Gro treatment affected more TAA and phenolic profile. Among nanoparticles, levan-coated nCeO(2) had the strongest and positive impact on tested plants. Wheat showed higher sensitivity to all treatments.",

AB  - The life-history traits and population dynamics of the black bullhead Ameiurus melas (Rafinesque) were studied monthly from August 2009 to December 2012 in Lake Sava in Belgrade (Serbia). This period included a mass mortality event in May 2011 and subsequent population recovery during 2012. Available evidence suggests the mass mortality was caused by European catfish virus that only affected the black bullhead. Changes in key life-history traits and the recovery potential (increase in catch-per-unit-effort, doubling of young-of-the-year to adult ratio, earlier maturation and increased fecundity) following the mass mortality event suggest population resilience typical of a recurring boom-bust pattern and demonstrate the species' capacity to recover rapidly and re-establish following disturbance. Repeated systematic mass removals of both juveniles and adults (using fyke nets) will be required if future fishery management measures aimed at limiting the population size are to be effective.

AB  - Fish communities are excellent indicators of biological and ecological integrity due to 
their continuous exposure to water conditions. Freshwater biodiversity constitute a valu able natural resource but extensive pollution of freshwater can result in biodiversity de cline. For that reason it is important to employ bioassays for purpose of detecting these 
conditions. In this work we monitored chub and bream species in 2 reservoirs, Uvac and 
Garasi, and 4 rivers: Dunav, Sava, Pestan and Beljanica. For assessment of metal and 
metalloid in fish tissues (liver, gills, gonads and muscle) we have used ICP-OES. The 
comet assay or single cell gel electrophoresis (SCGE) was selected as an in vivo geno toxicity assay, for measuring DNA damage in blood, liver and gills. Histopathological 
alterations were monitored in liver and gills.The high quality of Uvac water was con firmed by low values of DNA damage in all tissues compared to other sites. An analysis 
metals in tissues showed a high degree of their differentiation, as well as significant dif ferences in the distribution of tissue elements between the sites tested. The highest con centrations of most of the analyzed metals were found in gills, liver and gonads, and the 
lowest in muscles at all sites. In chub, blood showed the lowest DNA damage compared 
to liver and gills, while in all breams DNA damage was the highest in blood cells, follow ing gills and liver. Histopathological analysis performed on bream specimens on the Sava

AB  - Pontic shad (Alosa immaculata) is a migratory fish species, which undergoes long migrations along the Danube River, from Black Sea to the first obstacle that stops the migration the Iron Gate II dam.
Individuals used in this study were caught using drift nets, in 2018 (n=11) and 2019 (n=11), few kilometres down stream of the Iron Gate II Dam, near village of Prahovo, Serbia. Blood samples were taken from live individuals and two blood smears were prepared, on microscopic slides, for each individual. Slides were stained with Bio-Diff kit (Bio Optica, Milano, Italy) and observed and photographed under DM RB photomicroscope (Leica, Wetzlar, Germany). Pictures were analysed using the Digimizer image analysis software which automatically calculated celular and nuclear parameters of red blood cells.
The proportion of immature, intermediate, and mature erythrocytes were calculated and the differences in cellular and nuclear parameters were tested using the Mann-Whitney U test. Average length of the fish caught at 2018 was 31.9±3.9 cm, with the average weight of 188.9±48.9 g. Individuals from 2019 sampling had an average length of 29.6±2.7 cm, and the average weight of 147.2±57.5 g. Average value of Fulton’s condition factor did not differ between sampling seasons (K=0.57). Overall, in both years, immature erythrocytes constitute the majority (>57%) of analysed red blood cells. Individuals caught at 2018 had higher proportion of immature and intermediate cells, while fish caught at 2019 had higher proportion of mature cells- Man-Whitney U test showed no statistically significant differences in cell area, parameter and length between fish caught at different years.
The same morphometirc parameters, observed for nuceus, showed statistically significant differences. Our study shows that anadromous fish, such as pontic shad, which undergoes long migrations, have 2-2.5 times higher proportion of immature erytrocytes then potamodromous vimba bream (Vimba vimba), a medium distance migratory fish species.

AB  - Concentrations of As, Cr, Fe, Hg, Mn, Se and Zn were assessed by ICP-OES in muscle, gills, liver and gonads of ruffe and European perch of different age classes. Fish were caughtwith portablefish nets at the confluence of the Danube river and the Sava River, in Belgrade. Age-related differences in element concentration were assessed by ANOVA  and Tukeys (HSD) tests. In ruffe, liver is the main tissue for accumulation of Cu, Fe and Se in all age classes. Gills are the main tissue for accumalation of Mn, while gonads had a higher concentrations of all elements in liver (exept for Cr), while individuals aged 4+ had the highest element concentration in gonads (again, with the exception of Cr). However, these age-related differences in ruffe were not statistically significant. In European perch, the highest concentrations of As, Cu, Fe, Se and Zn in majority of age classes were found in the liver. Individuals aged 1+ and 2+ had the highest concentration of Hg in gills. In subsequent age classes, muscle was the main tissue for accumulation of this element. Contrary to ruffe, age-related differences were observed for Se in liver, where age classes 4+ and 5+ had higher concentrations than age-class 1+, as well as for Zn in gonads, where age classes 4+ and 5+ had higher concentrations than age-class 1+, as well as for zn in gonads, where age class 1+ had higher concentration than age class 3+.

AB  - Water pollution represents one of the main threats of global freshwater diversity. Untreated urban wastewaters are the source of both microbiological and chemical pollution. In exposed organisms, pollution affects different levels of biological organisation, from molecular to community level. Due to their role in aquatic ecosystems and vulnerability to pollution fish represent one of the key elements of ecosystem monitoring programs. Microbiological indicators of faecal pollution such as total coliforms, E. coli and enterococci are reliable indicators of the untreated urban wastewaters. They may be detected and quantified by fast and reliable enzymatic methods and most probable number (MPN) approach. Analysis of metals and metalloids concentrations in fish tissues indicate the exposure of fish to specific elements and can be used as a biomarker of accumulation. The single cell gel electrophoresis or comet assay is widely used in ecogenotoxicological studies for the assessment of the DNA damage as a biomarker of exposure to pollution. Histopathological alterations in fish tissues reveal changes at the middle level of biological organisation and are used as a biomarker of effect. Since each fish tissue responds differently to pollution it is recommended to perform these bioassays on multiple types of tissues, i.e.: blood, gills, liver, gonads, skin and muscle.
Analysis of different biomarkers response can give information about the early response of biota to pollution, before the changes in population structure and a decrease of individuals occur.

Due to their role in aquatic ecosystems and vulnerability to pollution fish represent one of the key elements of ecosystem monitoring programs. Microbiological indicators of faecal pollution such as total coliforms, E. coli and enterococci are reliable indicators of the untreated urban wastewaters. They may be detected and quantified by fast and reliable enzymatic methods and most probable number (MPN) approach. Analysis of metals and metalloids concentrations in fish tissues indicate the exposure of fish to specific elements and can be used as a biomarker of accumulation. The single cell gel electrophoresis or comet assay is widely used in ecogenotoxicological studies for the assessment of the DNA damage as a biomarker of exposure to pollution. Histopathological alterations in fish tissues reveal changes at the middle level of biological organisation and are used as a biomarker of effect. Since each fish tissue responds differently to pollution it is recommended to perform these bioassays on multiple types of tissues, i.e.: blood, gills, liver, gonads, skin and muscle.
Analysis of different biomarkers response can give information about the early response of biota to pollution, before the changes in population structure and a decrease of individuals occur.",

AB  - Due to the increasing industrialization, metals are discharged into all spheres of the environment, in particular, in river courses, which leads to the need for constant monitoring. Metals do not degrade into harmless end products; they are very persistent and have high potential for accumulation in biota. Metals in the fish body are accumulated in different amounts in the tissue specific matter. In relation to the biotic conditions and fish metabolism, the load of food, or the stage of the reproductive cycle, the seasonal variation of metal levels can be expected. Because of that, the objective of our present study was to analyze 15 metals and metalloids in liver, gills, muscle, and gonads of European chub (Squalius cephalus) throughout the 4 seasons, autumn, winter, spring, and summer. The specimens were collected from two rivers, Pestan and Beljanica at the Kolubara basin, and their concentrations were determined with inductively coupled plasma optical emission spectrometry (ICP-OES). Specimens from both rivers have shown similarities in metal accumulation like the highest accumulation of majority of elements in gills, lowest accumulation of majority of elements in muscle (except for Hg), and higher accumulation of some elements in summer (Cu, Fe, Zn). In addition, Cu and Fe showed affinity for liver, while Ba, Cr, Sr, and Zn were specific for gills. Also, Al, B, Fe, Ni, and Pb did not show significant differences in concentrations among different seasons in all investigated tissues.

AB  - Accumulation of 17 elements in muscle and liver of common nase and vimba bream, caught between February and May 2016 in the Danube River (1173 river kilometer), were assessed by ICP-OES. The principal component analysis grouped muscle and liver samples based on element concentrations (muscle grouped by higher Ba and Sr values, and liver grouped by higher Al, B, Cd, Cr, Cu, Fe, Mn, and Zn values), but no grouping between the two species was observed. Concentrations of Ba, Cu, Fe, and Zn were significantly higher in muscle, and concentrations of Ba, Cd, Cu, and Mn in liver of common nase, while vimba bream had significantly higher concentrations of Cr and Fe in liver. Common nase has a higher affinity for bioaccumulation of Cu, Fe, and Zn in muscle, while vimba bream has a higher affinity for Al, Cd, and Cr in muscle.

AB  - The paddlefish (Polyodon spathula) was first introduced to Europe in 1974, mainly due to its potential for rearing in natural polyculture ponds and large temperate reservoirs. The information on the history of paddlefish aquaculture efforts in Europe is scarce, as well as data on current paddlefish aquaculture status and trends. In addition, there is a lack of data on its presence and potential establishment in the wild, while its invasive potential and associated risks and impacts are largely unknown. In order to evaluate its current status in Europe, we conducted a survey among scientists, aquaculture producers and other stakeholders, and reviewed literature and data on the Internet. Based on the results obtained, we discuss the potential and the challenges in European paddlefish aquaculture development, and analyze paddlefish invasive potential and risks associated with its naturalization. Paddlefish aquaculture is well established only regionally in Europe, but offers relatively high potential for further development in pond farms. Nevertheless, future development will require careful planning, especially regarding market development and improved marketing strategies. While paddlefish likely represents a low-risk invader, improved control and reporting on trade and intentional and unintentional releases will be required. Given the lack of knowledge on potential impacts following its introduction, due caution seems highly advisable.

AB  - A four-parameter model of spectral sensitivity curves was developed. Empirical equations were designed for A(1)- and A(2)-based visual pigments with the main a-band maximum absorptions (lambda(max)) from 350 nm, near the ultraviolet, up to 635 nm in the far-red part of the spectrum. Subtraction of the alpha-band from the full absorbance spectrum left a "beta-band" described by a lambda(max)-dependent Gaussian equation. Compatibility of our templates with A(1)- and A(2)-based spectra was tested on the electroretinographic (ERG-derived) scotopic action spectra recorded in dogfish shark, eel, Prussian carp and perch. To more precisely estimate the accuracy of our model, we compared it with widely used templates for visual pigments. There was almost no difference between the tested models in fitting the above-mentioned spectral data. One of the advantages of our model is that in the fitting of spectral sensitivity data it uses non-transformed wavelengths and the shape of the curve remains the same for a broad range of lambda(max) values. Compared to multiparameter templates of other authors, our model was designed with fewer (four) parameters, which we believe can bring us closer to understanding the true nature of the absorption curve.

AB  - Climate change is expected to strongly affect freshwater fish communities. Combined with other anthropogenic drivers, the impacts may alter species spatio-temporal distributions and contribute to population declines and local extinctions. To provide timely management and conservation of fishes, it is relevant to identify species that will be most impacted by climate change and those that will be resilient. Species traits are considered a promising source of information on characteristics that influence resilience to various environmental conditions and impacts. To this end, we collated life-history traits and climatic niches of 443 European freshwater fish species and compared those identified as susceptible to climate change to those that are considered to be resilient. Significant differences were observed between the two groups in their distribution, life history, and climatic niche, with climate-change-susceptible species being distributed within the Mediterranean region, and being characterized by greater threat levels, lesser commercial relevance, lower vulnerability to fishing, smaller body and range size, and warmer thermal envelopes. Based on our results, we establish a list of species of highest priority for further research and monitoring regarding climate-change susceptibility within Europe. The presented approach represents a promising tool to efficiently assess large groups of species regarding their susceptibility to climate change and other threats, and to identify research and management priorities.

Significant differences were observed between the two groups in their distribution, life history, and climatic niche, with climate-change-susceptible species being distributed within the Mediterranean region, and being characterized by greater threat levels, lesser commercial relevance, lower vulnerability to fishing, smaller body and range size, and warmer thermal envelopes. Based on our results, we establish a list of species of highest priority for further research and monitoring regarding climate-change susceptibility within Europe. The presented approach represents a promising tool to efficiently assess large groups of species regarding their susceptibility to climate change and other threats, and to identify research and management priorities.",

AB  - Prey preference and seasonal variation in the diet of the Eurasian otter, Lutra lutra (Linnaeus, 1758), were examined by the analysis of 789 spraint samples collected along a 10-km section of a small lowland salmonid river in Serbia, with a trout farm situated in its lower part, from June 2009 to March 2012. Of particular interest was any possible impact of the otter on brown trout, which is important to investigate for preventing and managing any potential conflicts with fishers and fish farmers. Fish were by far the most important otter prey, followed by crayfish. Cottus gobio Linnaeus, 1758 (the European bullhead) was the most common prey species, probably because of the combination of its abundance and easy catchability. Other prey contributed very little to the diet of the otters. Of 11 fish species present in the river, five were found in the otter diet: the European bullhead, Salmo trutta Linnaeus, 1758 (brown trout), Squalius cephalus (Linnaeus, 1758) (chub), Barbus balcanicus Kotlik, Tsigenopoulos, Rab & Berrebi, 2002 (the Danube barbel), and Phoxinus phoxinus (Linnaeus, 1758) (the Eurasian minnow). The bullhead was the only positively selected species, however. The share of fish prey in the otter diet was stable throughout the year, except for a decrease noticed during the summer. The results suggest that otters on the River Gradac target smaller, sedentary, and less nutritious prey. Owing to a small percentage of brown trout in otter spraints, we surmise that otters do not represent a major biological or economic threat, either to the native trout population in the river or to the trout from the nearby fish farm. Although there are no reports of otters causing damage to the trout population in the local fish farm, it is advisable to establish mechanisms for the compensation of fish farmers in case such damage does occur. The data presented in this paper can be used to contribute to the conservation of the otter in stream habitats, especially because there are no published studies on the dietary requirements of otter in Serbia.
