Shellfish farming contributes to nutrient removal in coastal and estuarine systems, as bivalves incorporate nutrients into their tissues and shells, which is removed from the marine system on harvest. Fourteen locations around the UK were surveyed to explore geographic variation in carbon, nitrogen and phosphorus content of tissue and shell in blue mussels. Phosphorus in tissue had a significant negative relationship with mean annual seawater temperature for both rope and bottom cultured sites. Per tonne of live mussel, rope culture removed significantly more nitrogen (8.50 ± 0.59 kg) and phosphorus (0.95 ± 0.07 kg) than bottom cultured (5.00 ± 0.013 kg nitrogen and 0.43 ± 0.01 kg phosphorus). Bottom culture, however, provides significantly more C removal in shell (60.15 ± 0.77 kg) than in rope cultured (46.12 ± 1.69 kg). Further studies are required to examine the effect of growth rate, on the nitrogen and phosphorus remediation, and carbon stored in shell, of rope culture and bottom cultured mussel aquaculture.

Long-term data are essential for decision-making in the operation of constructed wetlands; however, such data are scarce. In the present study, a subsurface flow CW system was monitored over a 10-year period for the treatment of wastewater from the dairy industry. Prior to the CW, an aerated facultative lagoon was operated, and its data were also included in the study.

The combined impact of multiple human activities is the primary driver of coastal ecosystem degradation, and comprehending its mechanisms is essential for developing adaptive management strategies. A coastal ecosystem model coupling multiple human activities, including runoff discharge, reclamation, mariculture, and atmospheric deposition, was developed using the Regional Ocean Modeling System (ROMS) coupled with the Carbon, Silicate, and Nitrogen Ecosystem (CoSiNE) model. The model performance was rigorously evaluated in the Bohai Sea as the study area.

Tobacco bacterial wilt (TBW), caused by Ralstonia solanacearum, significantly impacts tobacco yield and quality, leading to substantial economic losses. This study investigated the effects of the microbial agents JX (Pichia sp. J1 and Klebsiella oxytoca ZS4) on the soil properties, rhizospheric microbial community, tobacco agronomic traits, and TBW incidence through field experiments.

Bacteria and Archaea are microorganisms that play key roles in the biogeochemical transformations that control water quality in freshwater ecosystems, such as in reservoirs. In this study, we characterize the prokaryotic community of a high-relevance tropical eutrophic reservoir using a 16S rRNA gene survey during a low-water level fluctuation period mainly used for storage, associating the distribution of these microorganisms with the hydrogeochemical conditions of the water column. Our findings revealed that diversity and structure of the prokaryotic community exhibited spatio-temporal variations driven by the annual circulation-stratification hydrodynamic cycle and are significantly correlated with the concentrations of dissolved oxygen (DO), soluble reactive phosphorus (SRP), and dissolved inorganic nitrogen (DIN).
