Indicative ecological status assessment of the Despotovica river

Kragujevac Journal of Science (2018)

B. Šimić Ana Petrović Nevena B. Đorđević Božica Vasiljević Nataša Radojković

The investigation of the Despotovica River was carried out in April 2017 with the aim to provide an indicative ecological status assessment. Phytobenthos and aquatic macroinvertebrate communities were followed as well as physico-chemical parameters of water. Ecological status assessment is given based on biological (epilithic diatoms and macroinvertebrates) and supporting physico-chemical water quality elements, according to the Serbian National regulation on parameters of ecological and chemical status of surface waters and parameters of chemical and quantitative status of ground waters. The ecological status was determined by the worst evaluated water quality element. Based on the analysis of investigated parameters of biological and physico-chemical water quality elements, the indicative ecological status of the Despotovica River could be assessed as bad (class V), which is the result of the river's load of organic and inorganic origin but also of heavy metals.

First record of the species Encyonema bonapartei Heudre, C.E.Wetzel & Ector (Cymbellales, Bacillariophyceae) in Serbia

Oceanological and Hydrobiological Studies (2024)

Božica Vasiljević Olga Jakovljević Jelena Krizmanić David Heudre Katarina Zorić

Encyonema bonapartei Heudre, C.E.Wetzel & Ector is a diatom species originally documented in 2016, following its discovery in three canals in the eastern region of France. In 2021, an extensive hydrobiological survey in a mountainous part of southwestern Serbia led to the first finding of this taxon outside of France, i.e. in the Uvac Special Nature Reserve – in Lake Zlatar (Zlatarsko jezero) and in the Marić River (Marića reka). Detailed light microscopy and scanning electron microscopy observations of a large population recorded in Lake Zlatar confirmed the unique morphological characteristics of E. bonapartei, which is also the first record for the diatom flora of Serbia. The present work provides new information on the distribution and ecological preferences of E. bonapartei, taking into account physical and chemical characteristics of its habitats in Serbia.

Trends in rainfall intensity for stormwater designs in Ontario

Journal of Water and Climate Change (2012)

Božica Vasiljević Edward A. McBean Bahram Gharabaghi

The intensities of short-duration rainfall events are fundamental inputs to the design of stormwater management infrastructure. However, since stormwater infrastructure must function as designed for many decades, if there are long-term trends in rainfall intensities, design storms need to be modified. Evidence demonstrates, using data from 13 rain gauges in Ontario, that storm intensities relevant to urban stormwater (5 year) appear to have changed over the last 30 years. The results show, for example, statistical significance at 80% confidence that the 5-year storm has increased, and 85% that the 2-year storm has increased, for the 1 h storm in Waterloo, using partial duration series (PDS) data. The PDS data indicate intensities are increasing at a rate of 1–3% per year. Results show, for example, that a 5-year recurrence storm for PDS for the period 1970–1984 is now very close in magnitude to a 2-year recurrence storm for the period 1985–2003 for Waterloo, Ontario. The implications for a case study demonstrate that 5 out of 12 storm sewer pipes in a subdivision would need to be increased in diameter to obtain the same level of stormwater performance.

Aquatic Insects (Ephemeroptera, Plecoptera and Trichoptera) metric as important tool in Water Quality Assessment in hilly and mountain streams

Bojana Tubić Стефан Анђус Katarina Zorić Božica Vasiljević Katarina Jovičić

The aim of the study was to test the significance of the EPT index in the water quality assessment of three types of water bodies in hilly and mountainous region of Serbia. The aquatic macroinvertebrate community was dominated by the group of insects, of which 95 taxa represent the EPT group. We compared the obtained values of biological indices used for the assessment of water quality according to the national legislation with the overall status assessment represented by the ecological quality classes (EQC). The results of the Spearman correlation test showed a negative correlation of EQC with the EPT index, BMWP score, H', total number of taxa and number of sensitive taxa, while a positive correlation was observed for the values of SI and Tubificinae %. The values of EQC and biological indices were subjected to principal component analysis (PCA). The results showed that the parameters that contributed most to the differences were the EPT index, the BMWP score and the number of sensitive taxa. The results indicate that the EPT index is an excellent indicator of changes in water quality and an important tool for the ecological categorization of water bodies in mountain regions.

Seasonal variations of microbiological parameters of water quality of the Velika Morava river Serbia

Archives of Biological Sciences (2012)

Stoimir Kolarević Jelena Knežević‐Vukčević Momír Paunović Božica Vasiljević Margareta Kračun‐Kolarević

In this study, we investigated the level of sanitary pollution and organic contamination of the Velika Morava River, the largest river in central Serbia. Samples of water for microbiological analysis were collected at 5 sites, monthly, from April 2010 to February 2011. Sanitary analysis, i.e. enumeration of total and fecal coliforms and intestinal enterococci, indicated moderate to critical fecal contamination, while organic load assessment (oligotroph to heterotroph ratio, index of phosphatase activity) revealed the category of moderately polluted water. We also investigated seasonal variations of these groups of bacteria and the factors that could contribute to these differences. Our results showed that the micro- biological quality of the water in the Velika Morava River during different seasons is affected by numerous factors such as unequal loading of wastewaters, solar irradiation, and relations of flow/dilution and rainfall/runoff.

The response of diatom community to small hydropower plant and fish farm

International Journal of Limnology (2024)

Olga Jakovljević Jelena Krizmanić Božica Vasiljević Slađana Popović

Some of the direct and indirect environmental impacts are related to the construction of fish farms (FFs) and small hydropower plants (SHPs) around the world. Diatom communities are one of the best bioindicators of various pressures like eutrophication, chemical and organic pollution. The main objective of this study was to examine the influence of SHP and FF on diatom community and water quality of the Prištavica River in Serbia. A total of 184 epilithic diatom taxa from 55 genera were identified. Sites after the FF and SHP are distinguished by the same dominant species in each season. Compared to the other sites, species diversity in summer was lower at site after SHP. In terms of spatial dynamics, four groups of taxa are distinguished. Some centric taxa were associated with sites downstream the FF and SHP. Altered physical and chemical parameters were documented at sites downstream of constructions. Water quality of the Prištavica River ranged from high to bad depending on diatom index, season, and sampling site. A greater difference in diatom index values was found at sites upstream and downstream of the FF, than at sites upstream and downstream of the SHP.

Diversity of Alien Macroinvertebrate Species in Serbian Waters

Water (2020)

Katarina Zorić Ana Atanacković Jelena Tomović Božica Vasiljević Bojana Tubić

This article provides the first comprehensive list of alien macroinvertebrate species registered and/or established in aquatic ecosystems in Serbia as a potential threat to native biodiversity. The list comprised field investigations, articles, grey literature, and unpublished data. Twenty-nine species of macroinvertebrates have been recorded since 1942, with a domination of the Ponto-Caspian faunistic elements. The majority of recorded species have broad distribution and are naturalized in the waters of Serbia, while occasional or single findings of seven taxa indicate that these species have failed to form populations. Presented results clearly show that the Danube is the main corridor for the introduction and spread of non-native species into Serbia.

A Water Quality Assessment Based on Benthic Diatoms of the Timok River Basin (Eastern Serbia) under Multiple Anthropogenic Pressures

N. Djukic Božica Vasiljević Djuradj Milošević Aleksandar Valjarević Tatjana Jakšić

The study is focused on diatom communities as indicators of the water quality of aquatic ecosystems.The study included watercourses of the Timok River Basin in eastern Serbia.Sampling of algological material and physicochemical measurements were conducted at 30 locations in September 2016.Non-metric multidimensional scaling (NMDS) showed that conductivity had an effect on the spatial variability of the diatom communities.At locations under influence of acid mine drainage along the Borska river, its tributaries and the Timok river, the diversity of benthic diatoms decreased and the abundance of metal tolerant taxa Achnanthidium minutissimum, Nitzschia capitellata and Nitzschia palea increased.Our study revealed that the combined effect of different pollutants significantly impacted on diatom assemblages; diatoms are good bioindicators of multiple pressures; and diatom indices with different types of pollution, may show an unreliable picture of the actual state, therefore, biological and physico-chemical parameters should also be observed when interpreting the results of a solely diatom-based assessment of the ecological condition of freshwaters.
