Summary: The content, isotopes, and budget of particulate lead (Pb) in the Changjiang Estuary and adjacent East China Sea were investigated to study the biogeochemical cycling of Pb in coastal seas. Particulate Pb originated from the Changjiang River, with higher concentrations in winter due to atmospheric deposition. The budget analysis revealed the significant input and export of Pb by the river and coastal currents, indicating the impact of pollution on Pb distribution in the study area.

Summary: This research investigates the influence of sea level rise (SLR) on riverine flooding in estuaries by simulating the morphodynamic evolution of an idealized estuary under different SLR scenarios. The results show that the estuarine response to SLR is affected by both morphological changes and changes in channel hydrodynamics. Interestingly, more severe SLR scenarios lead to a decrease in flood extent in upstream areas due to tidal energy penetration and erosion, which increases the channel capacity locally.

Summary: The Pearl River Delta has experienced significant changes in its hydro-morphology, with a reduction in water area by 21% and an increase in average water depth by 2.24 m. This study investigates the response of stratification in the Pearl River Estuary to morphological change and external forcing using three-dimensional numerical modeling. The results show that stratification exhibits distinct spatial and temporal variabilities, with human-induced morphological change enhancing stratification by up to four times. Future sea level rise would further enhance stratification, but to a lesser extent than past human impacts. Stratification in different areas of the estuary also responds differently to driving factors.

Summary: This study examined the cycling of dissolved organic nitrogen (DON) in the Bohai Sea and Yellow Sea in northern China. The results showed that the Yellow Sea had a stronger exchange with the open ocean, resulting in lower DON concentrations, while the Bohai Sea had a weaker exchange, leading to higher DON concentrations. Furthermore, this study discovered the molecular modifications in DON cycling.

Summary: The study aimed to assess the impacts of reduced river flow, rising sea levels, and increased nutrient discharge from anthropogenic sources on the estuarine environment. Results from seven different scenarios showed that both reduced river flow and rising sea levels led to increased salinities and decreased nutrient and chlorophyll-a concentrations in the middle and upper areas of the estuary. In the future, nutrients from anthropogenic sources may play a more significant role in shaping the spatial variability of phytoplankton communities.

Summary: A pioneering study using the HPLC-CHEMTAX analytical approach was conducted to investigate the dynamics of phytoplankton functional groups (PFGs) in the Ashtamudi estuary and its adjacent nearshore waters. The study found that the estuary exhibited high temperature, salinity, and ammonium levels during the non-monsoon seasons, while the summer monsoon resulted in low salinity and increased nitrate and phosphate concentrations. Cyanobacteria were the dominant phytoplankton community during the non-monsoon season, while diatoms dominated the nearshore waters. The study also revealed that the estuary was phosphorus-limited for phytoplankton growth during the non-monsoon seasons.

Summary: This study reconstructs the Holocene environmental evolution of the Oka estuary in northern Spain using sedimentary cores and a multi-proxy approach. The analysis of sediment and benthic foraminifera shows the transition from near-marine to brackish intertidal to salt-marsh environments. The relative sea-level record indicates a gradual shallowing of the estuary in the late Holocene, consistent with previous studies in northern Spain but with an earlier onset of the Highstand Systems Tract.

Summary: This study compared stable isotope evidence from British fossil wolves, carnivore competitors, and potential prey species from three different time periods. The results showed clear patterns of changing wolf prey choice over time, with the diet of wolves shifting from small and large prey during MIS 7c-a to large prey only during MIS 5a and a broader range of large prey during MIS 3. The study also revealed a lag between changing predatory behavior and morphological response in wolves.

Summary: Stable isotope analysis of animal tissue samples is used to study trophic ecology and shows that isotopic signatures respond to diet type and environmental conditions. In this study, brown bear hair samples from four populations in southwest Europe were analyzed, considering geographical and climatic differences. The study found inter-population differences in isotopic values that suggest differences in food consumption, with higher altitude populations showing a greater consumption of animal foods. The quantification of isotopic niche space identified significant similarities between two populations and highlighted the need for conservation measures for southern isolated populations.

Summary: By analyzing lake sediment deposits from the Ioannina basin in NW Greece, this study examines millennial-scale climate instability in southern Europe during Marine Isotope Stage 6 (MIS 6) around 185-130 ka. The data reveals warm/wet and cool/dry intervals associated with Asian Monsoon events and North Atlantic interstadials. The presence of high-amplitude oscillations in diatom species assemblages suggests sensitivity to environmental thresholds during this period of frequent and persistent climate instability.
