Since the Industrial Revolution, anthropogenic activities have substantially increased input of nitrogen (N) and phosphorus (P) into river basins, complexity by interplay with climate. This study analyzed characteristics N P inputs within Dawen River Basin from 2000 to 2021 using Net Anthropogenic Nitrogen Input (NANI) Phosphorus (NAPI) methods, explored how those variables respond precipitation temperature variability. We found a generally decreasing trend in NANI over time, an average 17,882.34 kg km-2 yr-1. In contrast, NAPI showed initially increasing then 2021, value 5,151.79 Fertilizer usage emerged as primary source nutrient inputs, accounting for approximately 63.42% 61.88% inputs. Precipitation positively impacted while exerted more influential but opposing effect. Time-lag effects were evident, demonstrated stronger influences preceding year on NAPI. Moreover, climate not only quantity also highly correlated their changes, well dynamics components. Through quantitative analyses, we unveiled key thresholds correlation between variables, cutoffs 14.1℃ 820 mm precipitation. These insights highlight complex relationship variability, underscoring importance sustainable management practices mitigate negative environmental impacts.

This study investigates the long-term trends (1992–2022) of nitrogen and phosphorus loadings exported by River Po to Adriatic Sea, better analyse how changes in hydrology are affecting timing magnitude river nutrient loads. We used 30 years monitoring data order (a) identify main temporal patterns their interactions at a decadal, annual seasonal scale, (b) estimate precipitation effects on load formation evaluate whether which extent hydrological regime affects export across (c) monthly scale transport dynamic N P chemical species (hydrological vs. biogeochemical control).

The Northern Adriatic is a dynamic and the most productive part of Sea. phytoplankton is, as many studies in this area showed, under heavy influence freshwater inputs anthropogenic pressures. Cluster analysis more than 20 year data set across steep spatio-temporal, ecological gradients on longitudinal transect northern Adriatic, allowed us to identify significant reoccurring species assemblages. Those clusters show stable seasonality relation environmental conditions are presumed be cornerstones important ecosystem services provided by phytoplankton.

Coastal areas represent delicate and complex environments due to the interconnection between land sea, where marine, fluvial anthropogenic stressors combine threatening undermining coastal health. Sea level rise increasing storminess, for instance, lead more frequent flooding habitat loss erosion; sediment supply by rivers, on other hand, helps balance restore loss. However, excessive riverine nutrient inputs may eutrophication phenomena, putting ecosystem as well communities at serious risk. Here, we compute high resolution (300 m) Chlorophyll-a (Chl) Total Suspended Matter (TSM, a proxy concentration) trends over Adriatic using single sensors MERIS (from 2003 2012) OLCI 2017–2024) data, study response of marine human and/or environmental pressures, thus detecting likely subject starvation.

Our results reveal Chl TSM northern part basin being positively correlated with during investigated period, both data. Increases/decreases outflow resulted positive/negative trends.

Intensified agricultural and urban activities have exacerbated nitrogen pollution, posing a severe threat to freshwater ecosystems, particularly under intensified urbanization activities. This study systematically examined Baiyangdian Lake (BYD) its principal inflowing rivers, namely Fu River (FH), Baigouyin (BGY), Xiaoyi (XY) characterize the spatio-temporal distribution, primary sources, impact on sediment microbial community structure. Results indicated pronounced seasonal variations in both pollution loads with riverine levels rising markedly from dry season (May) wet (August). Atmospheric deposition accounted for 43.9% of input season, whereas fertilizers sewage contributed 23.3 26.4%, respectively. Additionally, communities exhibited distinct temporal spatial patterns, significantly higher diversity species richness being during season. The, composition shifted, as evidenced by decline Proteobacteria increases Firmicutes Actinobacteriota . River-lake connectivity emerged critical factor, FH displaying notably index compared BGY XY rivers. Structural equation modeling (SEM) analysis further revealed that river-lake was positively correlated negatively α-diversity. These findings demonstrated directly influenced concentrations, which turn indirectly modulated diversity.
