As the largest semi-closed marine ecosystem in world, Black Sea has been heavily affected by human activities for a long time. Describing biodiversity of multi-trophic biota pelagic zone and identifying dominant environmental factors are prerequisites protecting sustainability ecosystems. However, up to now, taxonomic distributional information about is not clear. Here, we employed Tree-of-Life metabarcoding analyze eight communities Sea, investigated their biogeographical distribution,...
Environmental DNA (eDNA) metabarcoding is an effective method for studying fish communities but allows only estimation of relative species abundance (density/biomass). Here, we combine with the total eDNA amplified by our universal marker (teleo) using a quantitative (q)PCR approach to infer absolute species. We carried out 2850-km survey within Danube catchment spatial integrative sampling protocol coupled traditional electrofishing biomass and density estimation. Total concentrations were...
Microplastics (<5 mm) are an emerging threat to marine ecosystems and organisms, including fish. Recent studies have ranked the Black Sea as one of most plastic-polluted European seas. Although there is evidence microplastic ingestion in various fish species Sea, data for Romanian sector still lacking. This study presents first assessment abundance, color, shape, size gastrointestinal tract gills Engraulis encrasicolus (European anchovy) collected from different locations along coast (NW...
The NW Black Sea is an area with peculiar hydrological, hydrochemical and biological features (river plume dynamics, coastal upwelling, intense eutrophication, blooms algae). We determined the abundance distribution of two major groups Archaea (Crenarchaeota Euryarchaeota) in three contrasting sites from May to August 2004 estimate contribution non-extremophilic prokaryotic plankton. Using catalyzed reporter deposition-fluorescence situ hybridization, Euryarchaeota were found be particularly...
Abstract The Black Sea is the largest semi‐closed permanently anoxic basin on our planet with long‐term stratification. study aimed at describing microbial community taxonomic and functional composition within range of depths spanning across oxic/anoxic interface, to uncover factors behind both their vertical regional differentiation. 16S rRNA gene MiSeq sequencing was applied get data taxonomy, PICRUSt pipeline used infer profile. normoxic zone mainly inhabited by primary producers...
Plastic pollution is a global concern that has significant impact on marine life. widely used and become pervasive pollutant in environments. contamination been documented both environments biota. cetacean gastro-intestinal tract (GIT) content received limited attention, especially the Black Sea. This study aims to investigate plastic GITs of bottlenose dolphins harbour porpoises, introducing novel methodology. Given exploration this issue Sea, research predominantly focuses microplastic...
Macroalgal cultures are currently of great interest worldwide. Although along the Romanian Black Sea coast, there is no tradition in this sense, currently, a major developing direction exists, taking into consideration that overexploitation wild seaweed resources involves disturbance marine environment, with implications can sometimes be irreversible. Porphyra and Pyropia species (also known as nori algae) considered world’s most valuable mariculture algal products due to their high...
eDNA metabarcoding is an effective method for studying fish communities but allows only estimation of relative species abundance (density / biomass). Here, we combine with the total amplified by our universal marker (teleo) using a qPCR approach to infer absolute species. We carried out 2850 km survey within Danube catchment spatial integrative sampling protocol coupled traditional electrofishing biomass and density estimation. Total concentrations were highly correlated. The correlation...
The ability of bacteria to degrade organic pollutants influences their fate in the environment, impact on other biota and accumulation food web. aim this study was evaluate abundance expression activity catabolic genes targeting widespread pollutants, such as polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) hexachloro-cyclohexane (HCH) Black Sea water column sediments. Concentrations PAHs, PCBs HCH were determined by gas chromatography (GC) coupled mass spectrometry (MS)...
Ephedrine is an illicit drug, classified as precursor for methamphetamine, which also used stimulant, appetite suppressant, decongestant or asthma. In this study, novel molecularly imprinted polymer (MIP) films were prepared by sol-gel derived techniques, using N-(2-aminoethyl)-3-aminopropyltrimethoxysilane functional monomer, to recognize ephedrine from aqueous solutions. The obtained air-spraying the solutions, with various concentrations of monomer and template, on glass supports....
Wood density is an intricate trait that encapsulates water transport, growth, and productivity. It probably the most used parameter to deduce wood quality. In this study, of 81 European provenances Norway spruce tested in three provenance trials from Romanian Carpathians was analysed compared at 49 years after planting. We also correlations between provenances’ geographic coordinates, as well other traits, such diameter breast height, total survival rate. For genetic variance analysis each...
Abstract Plastic and marine litter is one of the current growing issues worldwide, affecting unique Black Sea ecosystem as well. Litter yearly monitored for assessing ecological status across Romanian beaches. We tested aerial drone-inspection or UAV method versus visual census efficiency monitoring on two beaches, located in Danube Delta area. The detection probability varied between size-category items, with 71 – 100% accuracy screening drone images. Our pilot study showed successful...
