Benthic communities contain some of the most threatened organisms in aquatic habitats due to different anthropogenic pressures. The high abundance microplastics sediments will continue increase future, further increasing probability interactions between macroinvertebrates and microplastics. In present study, a benthic community relatively pristine shallow pond was exposed either an environmentally relevant concentration microplastic mixture 80 g m-2 sediment, or control without addition...

This study was carried out at the Danube River and its tributaries during Joint Survey 4 (JDS4) expedition. Three freshwater benthic species were used to estimate quantity of microplastics (MPs): Corbicula spp., Limnodrilus hoffmeisteri (Claparede, 1862), Polypedilum nubeculosum (Meigen, 1804). Following kick sweep technique, individuals sampled using a hand net or dredge. In order number MP particles/individual particles/g wet body mass, mass total length all specimens measured. Alkaline...

The aim of this study was to reveal faunistic and diversity patterns assess the effects environmental factors on differentiation leech communities. This covers investigations 82 karst springs in Montenegro from 2009–2017. communities were analyzed respect five wellspring types – caves, sublacustrine, limnocrene, rheo-limnocrene rheocrene. percentage substrate aquatic vegetation cover recorded alongside water parameters. In total, 18 species identified, which two recently described as new for...

Urban waters are often neglected in biodiversity research; nonetheless, the number of aquatic microhabitats present a city and surrounding urban area is impressive. Twenty-two waterbodies Belgrade functional (FUA) were investigated for faunistic diversity patterns to assess effects environmental factors on differentiation Chironomidae assemblages. A total 66 chironomid taxa within four subfamilies was identified. Water quality at studied sites, expressed by water pollution index (WPI),...

Many morphologically similar species of the simuliid (Diptera: Simuliidae) subgenus Wilhelmia, Enderlein are difficult to distinguish. Thus, revision using various morphological, cytogenetic, and genetic analyses has been attempted. Neglected until now, Balkan Peninsula, a crossroad between Europe Anatolia, provides insight which could resolve problematic interrelationships taxa within this subgenus. To uncover status relations mtDNA was extracted from 47 individuals six morphospecies:...

The objective of this work is to analyze the effectiveness two widely used methods for collecting aquatic macroinvertebrate samples: semiquantitative kick and sweep (K&S) quantitative Surber net (SN) techniques. Based on our data, were fully comparable as regards analysis metrics most often in ecological status assessment (sensitivity/tolerance parameters), while K&S was found be more successful evaluation biodiversity. Thus, both could routine monitoring water bodies, according...

The genus Physa (= Physella) includes the most abundant and diverse freshwater gastropods native to North America. Due their invasive nature many species occur throughout world. species, acuta, has been introduced Europe, Africa, Asia Australia by human commerce migrating birds. This is widely distributed Serbia. aim of this study was explore genetic diversity P. acuta from Serbia, determine evolutionary relationships among Physidae populations America, Mexico Cuba Europe using sequences...

First detailed limnological study was performed from April 2003 to June 2008 in a 396.6 km long section of the Serbian Danube (divided three parts; 1260 r-km 863.4 r-km) examine community composition and spatial distribution Mollusca with special attention expansion Ponto-Caspian species, propagation invasive introduced species occurrence endemic species. samples were collected at 15 sites April, June, September November. We investigated distributions calculated faunistic similarity...

Chironomid larvae respond rapidly to environmental changes in aquatic ecosystems, with different species possessing degrees of tolerance. Consequently, this group is considered an effective and reliable indicator the ecological status. In study, relation between larval chironomid assemblages variables was examined at two sites on Kolubara River. The nonparametric Mann-Whitney U test did not confirm significant seasonal differences samples. Correspondence analysis indicated that study are...

Abstract Detailed limnological study of the Lake Srebrno (Serbia) bottom fauna was performed in March 2007. Investigations included qualitative, quantitative, and saprobiological analysis communities, physical chemical sediments determination chlorophyll a concentration, as well saprobic trophic status analyses. Samples were collected at eighteen sites distributed along shoreline deeper sections lake. Twenty taxa from nine macroinvertebrate groups recorded. Family Chironomidae had biggest...

This study is the result of extensive investigations leeches on Balkan Peninsula. Our aim was to detect actual and potential (modeled) distributions common Erpobdellidae species, identify their ecological differentiation with respect altitudinal waterbody type gradient. Although widespread, these species rarely live together. Intense competition avoided by preferences for different types habitats. confirmed Pearson correlation analyses that yielded negative results. Differentiation clarified...

The study was conducted on the Danube River, within project Joint Survey 3 (JDS3). main aim to estimate quantity of microplastics in aquatic ecosystems through passive biological monitoring. Three freshwater species were used for microplastic (MP) isolation from different taxonomic groups organisms: Mollusca, Oligochaeta, and Chironomidae (Diptera), with following species: Lithoglyphus naticoides (C. Pfeiffer, 1828), Limnodrilus hoffmeisteri (Claparede, 1862), Chironomus acutiventris...

<title>Abstract</title> The Danube flows through densely populated areas and is exposed to numerous stress factors such as dams, canalisation, agriculture, urbanisation, which cause most of the changes in catchment area. This paper highlights benefits using cutting-edge Machine Learning (ML) models on data gathered from Joint Survey 3 (JDS 3) dataset detect xenobiotics rivers reliable biomarkers. Recognized key indicators under Water Framework Directive, macroinvertebrate communities...

Aquatic plants include a complex group of different adaptable plant species that inhabit water basins. They are the primary producers, first link in food chain, and all other life forms aquatic environment depend on them. On hand, overgrowth canal network with vegetation, especially new, allochthonous species, has major impact functionality system. The pumping stations sewer as system for protecting agricultural urban units cannot respond adequately to new challenges. Hydromorphological...

The research area of Pančevačka Ada represents a protected habitat the third category. aim this work is to determine biodiversity studied and assess water quality based on macroinvertebrate community. samples were taken at four sites in 2023. At each site, collected three five transects using benthic dredge from boat. A total 61 taxa aquatic macroinvertebrates 15 taxonomic groups recorded study area. When analyzing entire community surveyed sites, greatest diversity was found Bela Stena site...

Within this study, the microbiological impact of wastewater on surface watercourses in territory city Belgrade was investigated. The presence Escherichia coli analyzed samples indicates a significant fecal contamination locations directly affected by wastewater. However, negative water quality also observed areas not close proximity to sewers. construction treatment plants could be great importance for preserving and maintaining ecological status waters Serbia.

The aim of the study is to assess effects six weirs towards macroinvertebrates and establish methodology for selection priority removal. Macroinvertebrates were collected from 12 sampling sites on rivers Kriva Reka (2), Pcinja (8) Kumanovska (2) upstream downstream selected weirs. degree similarity above below was used as ecological criteria participate in determining which could be subject removal or remain unchanged. Results showed that only weir city Palanka

Sponges in the large rivers within Danube River Basin (DRB) have not been adequately studied. Hence, aim of this work was to undertake an investigation on distribution sponge species and Sava rivers. Out 88 localities covered by study, sponges were found at 25 sites only (46 samples total). By using morphological (light scanning electron microscopy) genetic (28S rDNA sequencing) analysis, four determined: Ephydatia fluviatilis (Linnaeus, 1759), Spongilla lacustris Eunapius fragilis (Leidy,...
