Abstract Background Examining the effects of pesticides is difficult in regions such as Western Europe because relatively ubiquitous use agrochemicals and lack unaffected areas. To study a wide gradient agrochemical stress, we conducted Central Romania, where traditional agriculture, which assumed to less agrochemicals, exists adjacent intensive agriculture. We investigated potential land related stressors including on aquatic–terrestrial predator–prey relationships using stable isotope...
Ursu Lake is located in the Middle Miocene salt deposit of Central Romania. It stratified, and water column has three distinct masses: an upper freshwater-to-moderately saline stratum (0-3 m), intermediate exhibiting a steep halocline (3-3.5 lower hypersaline (4 m below) that euxinic (i.e. anoxic sulphidic). Recent studies have characterized lake's microbial taxonomy given rise to intriguing ecological questions. Here, we explore whether communities are dynamic or stable relation taxonomic...
The diel vertical migration (DVM) of planktonic cladocerans and copepods was investigated in Lake Ştiucii, a natural shallow lake from north-western Romania. aim this study to test the existence patterns for cladocerans, adult copepod development stages (copepodites nauplii) four sampling seasons: October 2004; January, April July 2005. main abiotic biotic factors influencing microcrustacean day night distributions were also analyzed: water temperature, dissolved oxygen, transparency;...
Abstract The present paper aims to characterize the algal communities from Balta Mică a Brăilei Nature Park in terms of their species richness and ability reflect water quality aquatic ecosystems they live in. Thirteen shallow floodplain lakes, both permanent temporary, were considered for study, with 16 sampling occasions 2012 2013. More than 300 taxa identified, green algae (Chlorophyta) being dominant phyla almost all sites. trophicity organic pollution reached high values 2012, probably...
The present paper investigates the validity of water mite species (Acari, Hydrachnidia) described from Romania by Motaş, Tanasachi and Orghidan. Romanian researchers “Emil Racoviţă” Speleology Institute, Academy, Bucharest, had a prolific activity between 1939 1963: among taxa new to science these authors, 34 3 subspecies their type localities in Romania. More than 50 years later, 23 one subspecie team coordinated Motaş are still valid. 17 were found all over Europe, while 7 not recorded...
Abstract Stream dwelling invertebrate populations are facing an ample array of stressors including the habitat imbalance caused by important floods. In this research we used a novel way to estimate impact floods upon substrate, utilising remote variable named “flash-flood potential” (FFP), which accounts for site slope and average upstream catchment. The results showed that certain groups sensitive influence FFP whereas other not. We propose as surrogate assessing stress imposed sediment...
Springs, as unique ecotonal habitats between surface and hypogean areas, are considered endangered aquatic ecosystems due to direct indirect human impacts climate change issues. They distinctive water that often inhabited by a diverse but mostly stenotypic group of organisms. The present study 31 springs from the Apuseni Mountains (the Romanian Carpathians) were classified rheocrene, helocrene, limnocrene based on their geomorphology hydrology. Samples three substrate types (rocks, sand,...
The amphipod species Pontogammarus maeoticus (Sovinskij, 1894) was identified in two locations from the Danube Delta, Romania (Sfântu Gheorghe and Sulina beaches) July 2019. This is an eurybiont species, able to withstand high salinity variations characteristic mixing fresh sea waters. individuals presented a special character their morphology, depression on basis of pereiopod V. present paper contributes knowledge existing fauna Black Sea coast area.
