	abstract = {The Chinese sleeper is one of the fastest-spreading invasive fish species in Eurasia. The species’ effects on native biota are largely adverse through competition and direct predation. In this study, we systematically reviewed 240 scientific publications to synthesize current knowledge on the Chinese sleeper’s morphology, invasion history, life-history attributes, habitat use, feeding habits, parasites and genetics. Our review revealed high variability in the diet, growth, and other life-history attributes, which may largely determine the invasion success of the species. We concluded the colonization of Chinese sleeper is expected to lead to declines in native species richness and abundance, particularly in small and vulnerable aquatic habitats. These habitats frequently serve as refuges for rare and protected fish species, including the European mudminnow, whose long-term persistence is uncertain due to the continued spread of Chinese sleeper. We identified significant knowledge gaps regarding the biology and potential impacts of Chinese sleeper. We emphasize the urgent need for stricter policy regulations to prevent further introductions and manage established populations. Additionally, we highlight the importance of more intensive monitoring programs and the adoption of modern, universal detection methods—such as environmental DNA—to facilitate early detection and improve management effectiveness of the Chinese sleeper.},

This study evaluated the acute effects of three widely used pesticides—pirimiphos-methyl (10 and 60 μg/L), propamocarb hydrochloride (40 and 80 μg/L), and 2,4-D (50 and 100 μg/L)—on the liver of common carp (Cyprinus carpio Linnaeus, 1758), a sentinel species in aquaculture, but also a species equally important in risk assessment and environmental monitoring. Fish were exposed for 96 h under controlled conditions, and histopathological, histochemical, and biochemical biomarkers were analyzed. All tested pesticides induced significant histopathological alterations, predominantly circulatory and degenerative changes, with severity increasing at higher concentrations. Propamocarb hydrochloride and 2,4-D caused more pronounced and partly irreversible hepatotoxicity compared to pirimiphos-methyl. The histochemical assessment revealed altered glycogen metabolism, while the biochemical assays showed inhibition of key liver enzymes, including ALAT, ASAT, ChE, and LDH, indicating disrupted metabolic processes. These findings highlight the vulnerability of aquatic organisms to pesticide exposure and support the use of fish liver biomarkers as effective tools in ecotoxicology research. The study also emphasizes the need for stricter regulation and environmental monitoring of pesticide contamination in aquatic ecosystems.},

The honey bee,Apis mellifera(Linnaeus, 1758), has uniquecharacteristics that could be successfully used to improve biomonitoring approaches inassessing environmental interactions.  Three apiaries with different rates of honey beecolony losses were included in the study—Dimovtsi, Plovdiv, and Krasnovo, Bulgaria.Male individuals (immature and mature) were collected from five colonies for each ofthe three apiaries and studied for histopathological changes in the gonads.  The resultsconcerning the rate of honey bee colony losses in the studied apiaries from 2022 and2023 showed honey bee losses in the tested colonies due to queen problems, which werereported for Plovdiv, as well as the death of honey bees or a reduction in their number to afew hundred bees in the colony. The chemical analysis showed the presence of differentorganic substances, such as Coumaphos, DEET (N, N-diethyl-M-toluamide), Fluvalinate,and Piperonyl-butoxide, in the alive and dead honey bee samples and those of food stocks(wax, pollen, and honey) within the hives.  Among the sample types, those of the deadhoney bees contained the greatest variety of pesticide residues, particularly in Plovdivand Dimovtsi, reinforcing the link between pesticide exposure and honey bee mortality.The histopathological alterations were mainly associated with the thinning of the coveringepithelium of the seminiferous tubules and the detachment of the basement membrane ofthe seminiferous tubules. The more severe histopathological lesion, necrosis, was observedin a higher degree of expression in the drones from Plovdiv, indicating a higher pollutionlevel in this region.},

	abstract = {This study evaluated the histopathological impact of three commonly used pesticides—pirimiphos-methyl, propamocarb hydrochloride, and 2,4-dichlorophenoxyacetic acid (2,4-D)—on the kidneys of common carp (Cyprinus carpio Linnaeus, 1758) after 96-h acute exposure. The histopathological analysis demonstrated that all three tested pesticides induced structural changes. The histopathological changes were assessed using a semi-quantitative scoring system and categorised into circulatory, degenerative, proliferative, and inflammatory alterations. While circulatory alterations were absent in all treatments, clear and statistically significant degenerative, proliferative, and inflammatory responses were recorded, which escalated with increasing pesticide concentrations. Additionally, various statistical analyses were conducted to evaluate the lesions in kidney structure and function. Before the statistical analysis, normality and variance homogeneity were assessed using the Shapiro–Wilk and Levene’s tests, respectively. Due to non-normal data distribution, non-parametric methods were applied. Hence, the non-parametric statistical methods showed distinct group-level differences in the kidney damage indices. The Kruskal–Wallis test revealed significant differences across treatments (p < 0.001), and Mann–Whitney U tests identified specific pairwise differences. The degenerative and proliferative lesions were most prominent in fish exposed to 2,4-D at 100 µg/L (IK = 34), followed by pirimiphos-methyl and propamocarb hydrochloride. Inflammatory changes were mainly observed in the pirimiphos-methyl groups. The histopathological lesions were concentration-dependent, with 2,4-D causing irreversible renal damage at higher concentrations. These findings highlight the nephrotoxic risks posed by common pesticides and validate that the use of histopathological indices, combined with robust non-parametric testing, provides a reliable approach to evaluating organ-specific pesticide toxicity. These biomarkers offer sensitive early warning indicators of environmental risk, reinforcing the suitability of common carp as a model species for ecotoxicological assessment.},

Our genetic analysis provided a firm phylogenetic position for this population showing that their nearest relative is Eudontomyzon danfordi which has a center of distribution in the mid-Danube tributary basin, the River Tisza’s catchment area. With the discovery and molecular confirmation of new specimens, this taxon’s known distribution is presented for the first time; and particularly, the southernmost distribution area is located within a Natura 2000 protected area.

This is particularly relevant due to the perceived limitation of fish movement to what is known as active dispersal. Fish migration is often confined to interconnected water bodies, underscoring the significance of dispersal for fish inhabiting isolated aquatic habitats. However, empirical evidence for a natural (i.e. not human‐mediated) mechanism has been limited. Here we explore and provide evidence for waterbird‐mediated endozoochory as a possible dispersal mechanism in various fish species and families. We force‐fed mallards</jats:bold> <jats:italic><jats:bold>Anas plathyrynchos</jats:bold></jats:italic> <jats:bold>with fertilised eggs of nine bony fish species, covering nine taxonomic families. We recovered viable embryos of five fish taxa in the faeces of mallard, proving the ability of fish eggs to survive the passing of the digestive system of waterbirds. Moreover, the recovered eggs successfully hatched into larvae in two fish species. Taking into the flight speed and numerosity of mallards, as well as the high abundance of fish eggs, our results highlight endozoochory of fish eggs by waterbirds as a possible significant, although likely rare natural dispersal mechanism that can occur across more species than previously known in freshwater fish.</jats:bold>},
