China has experienced rapid agricultural development over recent decades, accompanied by increased fertilizer consumption in croplands; yet, the trend and drivers of associated nitrous oxide (N2 O) emissions remain uncertain. The primary sources this uncertainty are coarse spatial variation activity data incomplete model representation N2 O response to management. Here, we provide new data-driven estimates cropland-N2 across 1990-2014, compiled using a global flux observation dataset,...
Abstract Unintended reactive nitrogen (N) losses from agriculture, energy and transportation pose significant environmental hazards, including eutrophication, acidification, water air pollution, biodiversity loss, human health risks climate change. The concept of a footprint (NF) emerges as pivotal metric, reflecting potential N in the entire production-consumption chain goods services used by an individual within defined timeframe. In pioneering assessment per capita NF Ukraine, key...
PERSEUS project aims to identify the most relevant pressures exerted on ecosystems of Southern European Seas (SES), highlighting knowledge and data gaps that endanger achievement SES Good Environmental Status (GES) as mandated by Marine Strategy Framework Directive (MSFD). A complementary approach has been adopted, a meta-analysis existing literature pressure/impact/knowledge summarized in tables related MSFD descriptors, discriminating open waters from coastal areas. comparative assessment...
Between 2004 and 2012, populations of Mediterranean mussel (Mytilus galloprovincialis) rapa whelk (Rapana venosa) from the coastal waters Zmiinyi Island (Black Sea) were assessed for distribution, abundance, size, age characteristics. Compared to 2004–2005, bed cover in 2012 decreased by 75.6%, maximum depth occurrence reduced 22–25 m 10–12 m, total biomass declined 44.6%. There was a concurrent decrease abundance demersal fishes dependent upon mussels as prey. We concluded that invasive has...
Burning of fossil fuels, application fertilisers, and livestock farming have greatly increased emissions reactive nitrogen (N). The consequent increase in atmospheric deposition N compounds has compromised air, soil water quality, ecosystems, human health wellbeing. Sulphate aerosols also affect climate dynamics by scattering solar radiation, leading to surface cooling and, indirectly, cloud formation precipitation. During 2021 (the pre-war year), the rates total over lower, middle upper...
The Black Sea ecosystem has three main sources of nutrient pollution: coastal, riverine and atmospheric inputs.Anthropogenically produced N transported to the coastal open sea zones is closely connected with excess nutrients supply that can result at acidification, eutrophication, excessive oxygen consumption hypoxia.The aim our work was estimate quantities tendencies wet dry depositions (N P) different origin Zmiinyi Island surface during 2004 -2010.Our study confirmed previous findings...
On the basis of chlorophyll "a", dissolved oxygen, total nitrogen and phosphorus concentrations measurements values Trophic index TRIX for 2004-2010 in Zmiinyi Island area Black Sea were calculated.Inter-annual dynamics is analysed.It has been shown that varied wide range between 3.1 6.9 corresponded to trophicity categories from low very high.Results seasonal analysis showed minimal monthly average most often found during winter summer period maximal spring autumn connected with intensity...
Summary Purpose of the work. To determine long-term shoreline dynamics in area from Danube Delta (DD) to Great Adzhalyk Estuary North-Western Black Sea (NWBS) over 1980–2020. Methodology. Space images LANDSAT and SENTINEL were processed semi-automatically using software QGIS, ArcMap10.5 DSAS. Conclusions. It was shown that statistic characteristics movement (NSM, SCE, WLR) NWBS characterised by high spatial variability. The maximal accretion accumulation depositions took place areas DD sand...
Purpose. To study the state of macrozoobenthos in Zmiinyi Island coastal zone 2016-2017. Methods. Standard methods sampling, determination, number and biomass estimation. Results. Results analysis biodiversity, structural characteristics taxonomic composition have been presented. Seasonal dynamics its has studied. Assessment marine environment quality performed based on metrics macrozoobenthos. Conclusions. Altogether, 132 taxa benthic invertebrates belonging to 10 biggest groups identified...
Summary Purpose of the work was to quantify and compare rates atmospheric bulk nitrogen (N) deposition natural wetland two managed areas within Lower Dniester catchment in 2011–2019. Methodology. To collect (dry wet) we used custom-made accumulative samplers. We determined dissolved inorganic N (DIN) compounds samples with ion chromatography water soluble total (TN) routine wet chemistry. Results Conclusions. Croplands basin have been recognized as a highly polluted being both local sink...
Abstract Monitoring aquatic vegetation, including both floating and emergent types, plays a crucial role in understanding the dynamics of freshwater ecosystems. Our research focused on Lower Dniester Basin Southern Ukraine, covering approximately 1800 square kilometers steppe plains wetlands. We applied traditional machine learning algorithms, specifically random forest boosting trees, to analyze Sentinel-2 satellite imagery for segmenting vegetation into types. methodology was validated...
Summary In the Dniester River catchment, human activities are causing excess nutrient loads and eutrophication in vital ecosystems. This study assesses annual changes aquatic vegetation cover accumulation (N, K, P) Delta region to aid targeted management. Delta, our reveals notable trends implications. Emergent has remained stable, with less than 1% variation, mouth adjacent during period of 2000–2021. However, this area often faced challenges from overgrowing floating summer time. Floating...
Summary Purpose of the work was to quantify riverine nitrogen (N) and phosphorus (P) loads Dniester Estuary estimate their contributions Black Sea over 2010–2019. Methodology. The data on monthly water discharge N P compounds concentrations in surface monitored in-situ were used. Results Discussion. Mean annual estuary 7.9±0.2 km3 (range: 5.6–14.2 km3). Higher variation discharges found Turunchuk River (variation coefficient 38%), 1.7 times higher than before confluence. Annual TN varied...
Results of the study bacterioplankton Dniester River estuary (liman) carried out in 2003-2018 have been generalized paper. The trophic status was determined terms numbers. It has found that 2011-2018 numbers bacteria were higher than those registered 2003-2010. Relationship established between and electrical conductivity, water transparency, chlorophyll a pheophytin concentration, total content phosphorus. microbiological regime Liman is formed under influence natural processes organic...
Purpose. To study hydrodynamic prerequisites of forming and to assess the volume subaqueous discharge Upper-Sarmatian aquifer into Kuyalnyk Estuary. Objects methods. Hydrodynamic model determining changes in direction exchange between groundwater surface water estuary based on ratio levels (pressures) has been taken as methodological basis. Results. It established many years’ hydrogeological hydrological observations (1950 - 2016) that estuary, depending hydrogeodynamic conditions with time,...
