AB  - Urban waters are often neglected in biodiversity research; nonetheless, the number of
aquatic microhabitats present in a city and the surrounding urban area is impressive. Twenty-two
waterbodies in the Belgrade functional urban area (FUA) were investigated for faunistic and diversity
patterns and to assess the effects of environmental factors on the differentiation of Chironomidae
assemblages. A total of 66 chironomid taxa within four subfamilies was identified. Water quality
at the studied sites, expressed by the water pollution index (WPI), varied significantly. K-means
clustering gave four homogenous groups of chironomid assemblages, which showed clear preferences
to specific habitat conditions and tolerance to anthropogenic pressures. These groups had high values
of alpha and beta diversity components. The main component of beta diversity was species turnover.
Waterbody type, water temperature, pH, nutrients and overall pollution were the most important
factors influencing the distribution and composition of chironomid assemblages, which revealed
clear preferences of each assemblage type to the category of waterbody type and tolerances to
environmental pressures.

AB  - The Danube is an outstanding river: It links more countries than any other river in the world. The Danube River Basin (DRB) collects waters from the territories of 19 European nations and it forms the international boundaries for eight of these. The river's largely eastward course has served as a corridor for both migration and trade, and a boundary between east and west strongly guarded for thousands of years. The multi-cultural setting makes transboundary issues extremely challenging. In this chapter we characterize and synthesize the natural features of the main river, its 10 major tributaries and the Danube Delta. We present extensive information and data on biodiversity, climate, topography and hydrology. We also describe in detail stressors like land use, sediment regime and (hydro-)morphology alteration, pollution, non-native species introduction or fragmentation by dams and also socio-economic properties. We reflect about their major, adverse consequences for the functioning of river ecosystems in the entire basin. We also introduce river basin authorities such as the International Commission for the Protection of the Danube River (ICPDR) identified as important and useful platforms for dialogue and debate of appropriate goals and their implementation, involvement of stakeholders and the public, but also as "translators" of scientific results.

Additionally, the chapter contains maps, photographs and data tables that allow in depth analyses of and comparison between physical and biological features of the Danube River Basin and other rivers in Europe.

AB  - Water bodies in Belgrade sub-urban area are under considerable anthropogenic pressure. Rivers
and channels discussed in this study pass through industrial zones, agricultural and urban areas,
and play an important role in draining atmospheric water and wastewater. Reservoirs in
Belgrade vicinity are also under diverse anthropogenic influence. Macroinvertebrate samples
were collected in June and September 2018 from 21 water bodies (9 rivers, 8 canals, and 4
reservoirs), following MHS sampling procedure. Chironomids were dominant in all samples
and as such, they were analyzed independently. A total of 69 chironomid taxa (48 – rivers, 29
– reservoirs and 25 – channels) were recorded, within 4 subfamilies (Prodiamesinae,
Orthocladinae, Tanypodinae and Chironominae). The most abundant species altogether was
Chironomus riparius, with highest abundance in Barička reka. In reservoirs, the most abundant
non-biting midges belong to genus Procladius and Ablabesmyia monilis agg. while in the
channels the most abundant were Parachironomus arcuatus agg. and Cricotopus sylvestris
group. High dominance of chironomids in macroinvertebrate communities, as well as the
chironomid community structure itself, suggest that they could be efficiently used for
assessment of anthropogenic pressure in sub-urban areas.

AB  - Many morphologically similar species of the simuliid (Diptera: Simuliidae) subgenus Wilhelmia, Enderlein are difficult to distinguish. Thus, the revision of the subgenus using various morphological, cytogenetic, and genetic analyses has been attempted. Neglected until now, the Balkan Peninsula, a crossroad between Europe and Anatolia, provides insight which could resolve problematic interrelationships of the taxa within this subgenus. To uncover the status and relations within the subgenus Wilhelmia, mtDNA was extracted from 47 individuals of six morphospecies: Simulium balcanicum (Enderlein, 1924), Simulium turgaicum Rubtsov, 1940, Simulium lineatum (Meigen, 1804), Simulium pseudequinum Séguy, 1921, Simulium equinum (Linnaeus, 1758), and Simulium paraequinum Puri, 1933 from 21 sites throughout the Balkan Peninsula. Phylogenetic analysis of the Wilhelmia species using mitochondrial DNA barcoding (COI) gene showed two major branches, the lineatum branch, which includes the lineages sergenti, paraequinum, and lineatum, and the equinum branch. In the equinum branch, the mtDNA sequences formed six clades, with high genetic distances, suggesting the existence of different species. Historically, the clades of the equinum branch appeared at numerous islands, perhaps as a result of allopatric speciation. The paraequinum lineage (lineatum branch) is composed of two species. However, six clades of the lineatum lineage overlapped with intra- and interspecific genetic distances. Our results revealed that the species S. balcanicum, S. pseudequinum B, and S. equinum were omnipresent in the Balkans. The results point to not only the fair diversity of Wilhelmia species in the Balkans, but also indicate that most Wilhelmia species live in sympatry.

AB  - The chironomid community in non-wadeable lotic systems was tested as a source of information in the construction of biological metrics which could be used into the bioassessment protocols of large rivers. In order to achieve this, we simultaneously patterned the chironomid community structure and environmental factors along the catchment of the Danube and Sava River. The Self organizing map (SOM) recognized and visualized three different structural types of chironomid community for different environmental properties, described by means of 7 significant abiotic factors (a multi-stressor gradient). Indicator species analysis revealed that the chironomid taxa most responsible for structural changes significantly varied in their abundance and frequency along the established environmental gradients. Out of 40 biological metrics based on the chironomid community, the multilayer perceptron (MLP), an supervised type of artificial neural network, derived 5 models in which the abundance of Paratrichocladius rufiventis, Orthocladiinae, Cricotopus spp., Cricotopus triannulatus agg. and Cricotopus/Orthocladius ratio achieved a significant relationship (the r Pearson's linear correlation coefficient > 0.7) with the multi stressor environment. The sensitivity analysis “partial derivatives” (PaD) method showed that all 5 biological metrics within the multi-stressor gradient were mostly influenced by dissolved organic carbon (DOC). Despite short and monotonous environmental gradients and the absence of reference conditions, the chironomid community structure and biological metrics predictably changed along the multistress range, showing a great potential for the bioassessment of large rivers.

AB  - Multimetric indices based on the aquatic macroinvertebrates are used in many bioassessment programs of freshwater ecosystems worldwide, simplifying complex biological data, but keeping a sufficient amount of information regarding the ecosystem health. Majority of them do not rely on data of the chironomid community due to the complicated identification and great natural variability which they show along the longitudinal gradient. In addition, all these routine monitoring programs are defined for smaller streams but not for large, non-wadeable rivers. Thus, we conducted the survey on two large rivers, the Danube and Sava River, forming a network of 96 sampling sites. The main goal of the study was to model the variability of chironomid-based metrics on the spatial gradients, and the environmental gradients which indicate different types of pollution. To realize this, macroinvertebrates, including Chironomidae larvae, were sampled applying multihabitat approach and simultaneously 16 environmental parameters were measured. Chironomid community structure was patterned using the Self-organizing map (SOM). This multivariate visualization technique constructed two dimensional neural networks where all sampling sites were ordinated and clustered into the three groups of neurons. Passively, not influencing previous ordination, we introduced 15 biotic metrics based on proportion of sensitive and tolerant chironomid taxa, and 17 environmental parameters, into the SOM. Component planes as an output of SOM analysis present a variability pattern for each passive parameter distributed on the SOM network, and a clearly formed gradient indicates a high influence of the parameter on the community pattern. In this study, natural variability (distance to source), conductivity, water elements from natural (nitrates, dissolved oxygen) and anthropogenic sources (orthophosphate and ammonium) and heavy metal pollution (Zn, Cu, As and Cd), formed clear gradients, indicating their important contribution to the chironomid community pattern. This was confirmed by the Kruskal–Wallis test, since the values of visualized parameters significantly differed (P<0.01) between groups of neurons obtained by SOM. The same analysis revealed 6 biotic metrics which concordantly changed together with significant environmental parameters on the SOM network. The variability of chironomid community was driven by longitudinal gradient and multiple stressors. The proportion of sensitive taxa regularly alternated along longitudinal gradient and became dominant in the community, indicating particular complex of stressors. Chironomid-based metrics showed promising variability pattern since they predictably changed along the both natural and stressors gradients. After the scoring system is established, this type of metrics could be included in the routine monitoring programs and provide useful information regarding the ecosystem health.

AB  - Community concordance within aquatic biota could provide useful information for improving the methods used in bioassessment and biodiversity conservation management. The main goal of the study was to investigate the mechanism of community concordance between macroinvertebrates and fish in a single river basin (South Morava river Basin, Serbia). In order to achieve this, a Self organizing map (SOM) ordinated and classified sampling sites based on the community structures of five different taxa groups (macroinveretbrates (MIB), fish (FSH), Chironomidae (CHI), Macroinvertebrates without Chironomidae (MWC) and the Ephemeroptera Plecoptera Trichioptera group (EPT)). SOM also revealed 6 environmental gradients along the groups tested that significantly changed their community structures. Using the results of the SOM analysis as the input, the Mantel test quantified the highest community concordance between FSH and MIB (r = 0.42) followed by FSH and CHI (r = 0.29). The lowest concordance was recorded between FSH and EPT (r = 0.14). The indicator species analysis (IndVal) revealed 39 species to be responsible for the community patterns obtained. The Geo-SOM visualized the spatial distribution of the IndVal taxa, revealing the generators of community concordance. The strength of community concordance depends on the variability of the data on the aquatic biota. Thus, having an appropriate sampling and statistical design as well as high taxonomic resolution, as some of the factors which increase the variability in the data set, could present community concordance between fish and macroinvertebrates in an unbiased way.

AB  - One of the main challenges in selecting suitable biological indicators of environmental degradation is to recognize the stressor-specific response signal and to separate it from the natural background variability, which can be accomplished by setting an appropriate statistical design, with an output that enables understanding of the recorded indicator signal. In this study we used artificial neural networks (self organizing map (SOM) and geo-self-organizing map (Geo-SOM)) to model and visualize the variability in the chironomid community of the Danube basin, as a model for large non-wadeable rivers. Geo-SOM analysis visualized the longitudinal distribution of significant parameters defining different spatial-distributional types of anthropogenic disturbance. Chironomidae larvae, sampled in both shallow (river bank) and deep (middle) parts of the river, emphasized hydromorphological degradation and zinc as the most important stressing factors, with chlorophyll-a and suspended solids as accompanying variables influencing the community structure. Substrate specificity was shown to be a relevant factor influencing the variability within chironomid community structure bound to natural causes. Geo-SOM analysis also visualized the longitudinal distribution of chironomid taxa, following the distribution patterns of significant disturbance factors. The Kruskal–Wallis test validated 25 potential indicators for the shore area and 11 for the deep water area, which significantly changed their frequencies and abundances between classes with different extents of degradation. Due to its high taxonomical and ecological diversity, the Chironomidae family is a significant source of potential stress-specific indicators, which should be recognized and included in the future in relevant bioassessment methods. The artificial neural network could be a powerful tool for selecting reliable indicators to explain the variability found in the ecosystem and enable it to be specified and patterned together with environmental degradation.
