Article
Full-text available
Local environmental factors and dispersal-based processes can both influence the structure of metacommunities in freshwater ecosystems. Describing these patterns is especially important for biomonitoring approaches that are based on inferences made from benthic macroinvertebrate assemblages. Here, we examine the metacommunity structure of chironomi...
Article
Full-text available
There is a consensus that human activities affect biodiversity in pond ecosystems. However, the majority of studies have mainly focused on the direct effect of human activities on a single group, despite the fact that anthropogenically induced biodiversity loss in ecosystems occurs across multiple trophic levels and may depend on both altered habit...
Article
Full-text available
This paper shows the suitability of commercial production of the blackthorn (Prunus spinosa) as an generative rootstock for species from Prunus genus (plums, apricots and peaches cultivars). The aim of this study was to determine the germination of blackthorn seeds during outdoor stratification and blackthorn's seedlings transplanting transition. T...
Book
Full-text available
This book presents 67 species of dragonflies that have been recorded on the territory of Serbia. We wish to introduce this insect group to the young biologists and nature enthusiasts and to provide simple guide for their distinction in nature. For each species there is a short description, providing characters that distinguish them from the similar...
Article
Full-text available
This study was conducted in order to formulate a modification of standard substrate for laboratory bioassays (OECD protocol number 218: "Sediment water chironomid toxicity test using spiked sediment"), with as few constituents as possible, yet enabling the highest larval survival of model organism: Chironomus tentans (Chironomidae, Diptera). Labora...
Conference Paper
Full-text available
The potential of two chironomid species: Chironmus riparius and C. tentans in bioindication with the focus on relevant endpoints in assessing nanoparticle ecotoxicity in fresh waters.
Conference Paper
Full-text available
This conference paper presents our research on CeO2 nanoparticle toxicity to freshwater midge C. tentans and points out relevant endpoints that are sensitive detectors of nano-CeO2 presence in the sediments.
Article
Full-text available
While several studies have tested the effects of anthropogenic factors on specific taxa in ponds, the simultaneous effects of the overall anthropogenic pressure along the environmental gradient on the diversity of different groups of pond communities remain unknown. In this study, we evaluated the simultaneous effects of the overall intensity of hu...
Conference Paper
Full-text available
Identifying the anthropogenic drivers of biodiversity loss in ponds is important since ponds serve as biodiversity “hot spots” within regions. Previous studies on ponds biodiversity were mainly focused on the effects of anthropogenic factors on specific community in ponds, leaving the effect of multiple stressors on several trophic levels unknown...
Conference Paper
Different modifications of standard substrate for the OECD test No. 218 (5 different substrates) were tested in order to investigate the influence of substrate components on mentum deformities of C. tentans larvae. Mentum deformities could be good indicators of toxin presence in the environment, so the substrate in standardized tests should cause a...
Article
The present study was carried out in order to assess the influence of environmentally relevant concentrations of TiO2 nanoparticles (E171 human food grade) toxicity on the freshwater midge Chironomus tentans. Tested concentrations were 125, 250, 500, 1000, 2000 and 4000 mg of E171 TiO2 per 1 kg of sediment, for the experiment aiming at life trait t...
Article
The lotic habitats affected by trout farm waste are colonized with a particular invertebrate community of which chironomids are the most abundant group. However, there is little information available regarding how chironomid community structures respond to this type of pollution at the highest taxonomic resolution. Eight fish farms, together with t...

- Chironomus tentans was exposed to food grade E171 TiO2 nanoparticles - Mouthpart deformities of chironomids were analyzed with geometric morphometry - Dietary exposure to TiO2 caused losing the first inner tooth in the mandibles - Mortality and emergence ratio were affected with higher concentrations (>1000 mg/kg)
Conference Paper
Full-text available
Fauna of dragonflies and damselflies (Odonata) has been studied from 2013. to 2016. on the locality of Delijski Vis (near the city of Niš, 43°17'34'' N, 21°56'02'' E, altitude 341 ). Field research was conducted during all four seasons and faunistic lists were made. 30 species were found on this site, which represent 46.15% of Serbian Odonata fau...
Conference Paper

The effect on mouthpart morphological changes was investigated by the geometric morphometric approach.
Conference Paper
Full-text available
This study was conducted on 215 mandibles of 22 species, distributed in four subfamilies (Chironominae, Orthocladiinae, Diamesinae and Prodiamesinae), which are collected in rivers of the Danube basin.
Article
Full-text available
Due to their complex and interesting life cycle and alarming conservation status the Large Blue butterflies have become one of the most studied group of insects in Europe. In Serbia, however, Phengaris teleius has recently been discovered (in the far north of the country) and, since this initial finding, significant efforts have been made to map th...
Conference Paper
Full-text available
The Chironomidae family presents the most divers and abundant group of aquatic insects. At the larval stage, chironomids have very important role in aquatic ecosystems regarding detritus processing, and present an important part food chains. Exhibiting different ecological profiles and feeding types, chironomids belong to all previously defined fun...
Article
Full-text available
The paper provides an overview on the distribution of recently discovered Scarce Large Blue (Phengaris (Maculinea) teleius) in northern Serbia (Selevenj Sands, Ludaš Lake and Su- botica Sands). Mapping of the butterfly and its habitat has shown that most of the suitable habitats are limited to protected areas where at least some of the wet meadows...
Article
Full-text available
Dragonfly fauna of the Ovčar-Kablar Gorge was surveyed during April, May and July 2011. This paper presents the list of recorded species. Previous literature data are marked as questionable and therefore excluded from the final list.

The article presents the results of research of butterfly species at Ženeva pond near the river Nišava (SE Serbia). In all, the total of 45 species was recorded, representing 23% of Serbian butterfly fauna. Among species recorded, 4 are listed in Red data book of Serbian butterflies and are declared strictly protected in the country, while two are...

The main goal of this study is to investigate the differences in qualitative and quantitative structure of fish and macrobenthic fauna within distant, but hydromorphologicaly similar aquatic ecosystems. This research could further revile the trophic relations between fish and macrozoobenthos and the possibilities to apply these results to the development of sustainable aquaculture.
