In the first review of potentially toxic elements (PTEs) in fish in water ecosystems in Serbia, 40 studies related to fish contamination with PTEs were identified and evaluated. Studies of concentrations of PTEs in fish tissues covered 28 ecosystems (108 localities). The main studied river ecosystems were the Danube and the Sava, and the Međuvršje...

Uniform Manifold Approximation and Projection (UMAP) is a nonlinear dimension reduction technique based on manifold learning. It is specifically designed to achieve a balance between the global and local structure when embedding data points. We applied this method to morphometric features in populations of the noble crayfish, a freshwater species r...

This paper reports the accumulation of potentially toxic elements (PTEs) in trout (Salmo trutta L.) sampled from rivers Raška and Studenica in Serbia, which are assumed to be free of pollutants. The presence of PTEs, essential elements and heavy metals, in aquatic ecosystems is usually a consequence of anthropogenic activities such as mining, agric...

This paper presents the feeding habits of specimens of the fish Alburnus alburnus (L.) that inhabit the Gruža and Gazivode reservoirs. The diets of 37 specimens from Gruža reservoir and 44 specimens from Gazivode reservoir were analyzed. The common bleak from Gazivode reservoir fed more diversely on eight different prey items, while six different p...

Concentrations of Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sn, and Zn were detected in the muscle and gills of Prussian carp from three different freshwater ecosystems: isolated ponds and the South Morava River in Serbia, and Kopačko Lake in complex wetland ecosystem of the Kopački Rit Nature Reserve in Croatia. The main goals of the present...

European perch, Perca fluviatilis Linnaeus, 1758 and roach, Rutilus rutilus (Linnaeus, 1758) are the most common species present in mesotrophic and eutrophic lakes throughout Europe. Their biomass, especially in juvenile stages, contributes the most to the fish production of these ecosystems. In Bovan Reservoir, these two species constitute the bul...

Small lakes and ponds are among the most sensitive ecosystems, vulnerable to changes that have little or no effect on larger water bodies. Therefore this topic should be given more attention around the world. Anthropogenic impacts, which have been extensively researched in larger water bodies, have been barely examined in small lakes and ponds. Con...

The presence of microplastics (MPs) in the gastrointestinal tract, muscle, and whole-body samples of common bleak Alburnus alburnus L. from Gruža Reservoir (Central Serbia) was studied for the first time. Different protocols for MPs extraction were applied to determine the most efficient one. The study aimed to modify existing protocols to be cost-...

The extinction of species and the decline of biodiversity are the most severe global consequences of environmental threats. The decline of biodiversity is far greater in freshwater ecosystems than in the most threatened terrestrial ecosystems, and the most vulnerable are invertebrates, such as freshwater crayfish. Even one-third of freshwater crayf...

Concentrations of Al, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, Sn, and Zn were detected in the muscle and gills of Prussian carp from three different freshwater ecosystems: isolated ponds and the South Morava River in Serbia, and Kopačko Lake in complex wetland ecosystem of the Kopački Rit Nature Reserve in Croatia. The main goals of the paper w...

The aim of this study was to investigate the diet of adult predatory fish (pikeperch, perch, pike, and catfish) that inhabit the Bovan reservoir and determine their impact on the ecological stability of the reservoir. The results showed that predators most often used planktivorous fish species in their diet, including bleak, roach, and perch. These...

The utilization of fish bioindicators has become of crucial importance for ecosystem contamination assessment. Bleak (Alburnus alburnus) is a widely distributed epipelagic fish species characterized as very active with fast metabolism which can lead to a high accumulation of pollutants in tissues. Bleak is easy to sample, identify in the field by m...

The noble crayfish is one of the three autochthonous species that inhabit the freshwater ecosystems of Serbia, along with stone and Danube crayfish. The noble crayfish has a complex historical and genetic status shaped by geological events, habitat loss, pollution, translocations, and reintroductions of both autochthonous and allochthonous crayfish...

Western vairone Telestes souffia (Risso, 1827) is a small-sized leuciscine species inhabiting rivers in Mediterranean, North and Black Sea drainages. Due to the lack of information on its occurrence in the waters of Serbia, there is a need for renewing knowledge about its geographical range. The new record of a population of T. souffia in Gračanica...

The objective of this study was to develop a successful freezing protocol for cryopreservation of Danube barbel sperm, and to identify the presence of different spermatozoa subpopulations. By testing different concentrations of different cryoprotectants, we determined that the use of 5% dimethyl sulfoxide (DMSO) yielded the highest total motility o...

The concentrations of 14 potentially toxic elements in freshwater and marine sardines from the Western Balkan Peninsula were determined. In Prespa Lake, a natural lake, the concentrations of toxic Pb and Cd were above the maximum permissible concentrations in freshwater sardines. The As concentrations were elevated in sardines from Boka Kotorska Ba...

In the present study, landmark-based geometric morphometrics was applied to compare and visualize the overall size and shape variation, sexual size and shape dimorphism of the species Barbus balcanicus Kotlík, Tsigenopoulos, Ráb & Berrebi from different fragmented localities. The body shape of the fish was significantly different both for sex and l...

The Velika Morava River is the greatest national Serbian river and the significant tributary of the Danube River. The major problems in the Velika Morava River Basin (VMRB) represent untreated industrial and municipal wastewaters. In this study, the level of genotoxic potential at the sites along the VMRB was evaluated by parallel in vitro and in s...

The morphometric variation among several populations of Astacus astacus from different regions of the Balkan Peninsula was studied based on a large set of morphometric parameters per crayfish. Differences in morphometry among populations from ten water bodies in Serbia, Slovenia and Albania were tested using a multiple discriminant analysis. Analys...

In this manuscript we investigated the ability of stem, leaf and whole plant species Polygonum amphibium L. to absorb and accumulate some elements (Fe, Pb, Cd, Cu, Mn, Hg, As). Concentrations of the investigated elements in the sediment and plant material were higher than their concentrations in water, while the content of the studied elements in p...

In this study we have performed a comprehensive genotoxicological survey along the 900 rkm of the Sava River. In total, 12 sites were chosen in compliance with the goals of GLOBAQUA project dealing with the effects of multiple stressors on biodiversity and functioning of aquatic ecosystems. The genotoxic potential was assessed using a complex batte...

The performance of both adsorption and heterogeneous photo-Fenton processes, combined for the first time for the treatment of a real winery wastewater (WW), was evaluated under different operational conditions. A Portuguese natural Ca-smectite (Ca-Sm) was applied in both processes, however, with different purposes: (1) as an adsorbent, which reveal...

The main objectives of study were to determine the concentrations of As and other trace elements (Al, Co, Fe, Ni, Sn, Se) in the muscle, liver and gills of pikeperch (Sander lucioperca), catfish (Silurus glanis) and pike (Esox lucius) and in the muscle of Prussian carp (Carassius gibelio) and freshwater bream (Abramis brama), to identify relationsh...

Pikeperch (Sander lucioperca), catfish (Silurus glanis) and pike (Esox lucius) were collected from the Bovan Reservoir (Southeast Serbia), and samples of muscle, liver and gills were analyzed for Cu, Zn, Pb, Cd, Hg, Cr and Mn using inductively coupled plasma optical emission spectrometry (ICP-OES) and inductively coupled plasma mass spectrometry (I...

The concentrations of iron, lead, cadmium, copper, manganese, mercury and arsenic were measured in water, sediment, five macrophytes (Typha angustifolia, Iris pseudacorus, Polygonum amphybium, Myriophyllum spicatum and Lemna gibba) and five fish species (Sander lucioperca, Abramis brama, Carassius gibelio, Silurus glanis and Arystichtys nobilis) in...
