This study assesses surface water quality along the Sf. Gheorghe Branch of the Danube Delta (km 85-km 15) and adjacent control sectors, in order to assess the influence of both natural processes and anthropogenic pressures on aquatic environmental conditions. In situ measurements were performed at 97 stations during the June and September 2025 campaigns using a YSI EXO2 multiparameter probe. The monitored indicators were temperature, pH, dissolved oxygen, conductivity, total dissolved solids, salinity, turbidity, ...

Generally, water quality involves the water-s physical-chemical and biological attributes that depend on the natural surrounding environment and anthropogenic impacts. Through the years, the river water quality in the Sf. Gheorghe Branch has been subjected to various hydro-sedimentary impacts, due to the anthropogenic meander cut-off plans initiated for navigational objectives. In this study, the Sf. Gheorghe Branch water quality evaluation was performed using in-situ observations, measurements, and datasets provi...

The Danube Delta is a wetland of global importance, providing several ecosystem services. The sustainable development (i.e., economic, social and environmental) in the area depends on the health, quality and quantity of the natural resources. Water is one of the most important resources. Largely, the Danube Delta, which receives the input of water and sediment flux from the Danube River, gathered form its entire basin, may experiences lower water quality due to natural and anthropogenic factors, from basin to loca...

This paper presents the findings of the mapping and evaluation of macrophyte vegetation from Tataru and Uzlina lakes, located within Danube Delta, Romania. Throughout time, the Danube Delta unique ecosystem has endured considerable ecological changes due to natural and anthropogenic stressors. Currently, the potential threats are those related to pollution, agriculture, land use, climate change and subsequently, the proliferation and/or the extinction of many macrophyte species. The excessive development of aquati...

Asellus aquaticus Linnaeus, 1758 is the widespread and common Palearctic freshwater isopod, feeding on detritus. This crustacean, probably, has its ancient evolutionary origins around Siberia and has spread from there to Western Europe and North America. Commonly associated with a temperate climate, it has been recorded as far south as the Mediterranean, and as far north as Scandinavia. The species is primarily associated with the b-mesosaprobic waters of the palearctic realm i.e., high concentrations of dissolved...
