Increasing pollution of aquatic ecosystems due to anthropogenic activities underscores the urgent need for effective water quality monitoring. This study evaluates use fish scales from chub (Squalius cephalus) and nase (Chondrostoma nasus) as non-invasive bioindicators trace macroelement in Maros/Mureș River. We conducted qualitative quantitative elemental analyses using X-ray fluorescence (XRF) inductively coupled plasma optical emission spectrometry (ICP-OES). Scanning electron microscopy...
Studying contemporary and subfossil Cladocera (Crustacea) communities, we explored the effect of top-down stressors on cladoceran communities; are also interested in coherence communities. The studied Cibakháza oxbow lake is E Hungary, left-floodplain River Tisza; it a large, long, shallow lake. Three areas were distinguished based strength stress: protected area with low stress, biomanipulated high recreational moderate stress. Altogether, identified 28 taxa communities We found that...
We investigated the effect of land use based on dominant phytoplankton and physical-chemical variables in different areas Tigris River, within city Mosul. Agricultural urban activities have a significant impact water quality river. Regardless physical chemical variables, act as bio-indicator due to their fast sensitive response changes environment. Our research was conducted River Mosul by examining species at 16 sites during each vegetation period. Point non-point source pollutants affected...
During our work, we investigated the physical and chemical variables of a small surface watercourse to investigate how different anthropogenic effects affect its water quality. Along this watercourse, there are well-separated areas that affected by various effects. In addition origin branches, in many places it is surrounded agricultural land with insufficient buffer zones, which burdens nitrogen phosphorus forms. lower stages, artificial damming inhibits natural flow Tócó Canal, thereby...
Cladocerans are biological indicators of environmental changes. Their remains provide information on past changes in lake environments. We studied the correspondence between contemporary Cladocera assemblages and their subfossil from an oxbow lake. sought to demonstrate that there were differences among various sites with different utilization based physical–chemical variables. The lake’s two sides used as fishing sites, where angling is main activity. middle site under nature protection...
The life cycle of diatoms and dinoflagellates enables them to produce interannually varying dominances.This variability results from life-cycle interactions, physical conditions, inter-species competition for nutrients light.In particular, the overall dominant species year can be linked abundances resting stages temperature in spring.The aim this study was investigate effects as biotic factors on spring phytoplankton blooms caused by Stephanodiscus minutulus (Kützing) Cleve & Möller...
In our work, we sought to answer whether find differences among the various zones of an oxbow lake with different land uses based on physico-chemical variables and dominant algal plankton species. The two ends are bordered by settlements, near them there open water areas where fishing is major utilization form. Between a protected area large aquatic plant coverage transition towards areas. receives periodic replenishment only at one end from During summer—due lack rain—the used for...
Mediation of aquatic species has become an increasing problem for the last few decades. With commercial import, species' direct or indirect spread can gain more space. There are several ways them to land in their new home and through country. Most by waterways, boats, vehicles, even with help humans. Cladocerans have a good dispersal ability, thanks small size, additionally they possess adaptation, mechanisms develop resting eggs. Benthic littoral be mediated much easily due living space,...
Here we report the results of our decades-long study on epiphytic communities from two tributary systems Szigetköz section Danube River. The main goal investigation was to detect changes in at structural (core species, relative abundance common species) and functional (trait changes) levels as a result most important anthropogenic effects Szigetköz, i.e., hydro-morphological modifications. We also examined impact rehabilitation terms ecological potential. discovered that mainly motile diatom...
One of the main threats our time is increasing water demand not only globally, but also locally. These are often met at expense ecological demand, jeopardizing structural and operational conditions necessary to maintain good status in aquatic wetland habitats. This why it great importance explore possible retention options. In 2019, based on long-term data series level River Tisza, we studied frequency extent flooding floodplain between Tiszabercel Gávavencsellő, where there valuable...
