Summary: The study found that phosphate and ammonium levels were lower during the dry season, while there was enrichment of ammonium, phosphate, and chlorophyll a during the rainy season. The research showed that the overall water quality in the Gulf of Papagayo was adequate, but specific areas like Culebra Bay could potentially experience deterioration in water quality.

Summary: This study evaluated the behavior of three pomegranate cultivars under increased salt concentrations, showing diverse responses in nutrient accumulation, chlorophyll and carotenoid concentrations, photosynthetic rate and stomatal conductance. 'Wonderful' and 'Ermioni' cultivars exhibited higher salt tolerance potential and could be cultivated under marginal saline conditions.

Summary: The study showed that extreme salinity transients are the key factor triggering total destruction of activated sludge. The new waste management strategy proved that a stable microbial community could be maintained even when continuously exposed to a salinity level of around 10,000 mu S cm(-1) in the reactor, as long as variations remained limited to +/- 500 mu S cm(-1), ensuring satisfactory effluent quality.

Summary: This study compared environmental conditions and phytoplankton biomass/composition in three Texas estuaries with different freshwater inflow regimes to understand the impact of freshwater inflow on phytoplankton communities. The results showed that despite differences in freshwater inflow, salinity, and nutrient regimes, differences in phytoplankton community composition were relatively small, indicating the influence of other factors.

Summary: This article introduces an industrial production method for purifying high salinity brine and conducting evaporative crystallization, which can effectively reduce the concentration of Ca2+ and Mg2+, extend the production cycle and inhibit the accumulation of deposits, and produce NaCl and Na2SO4 crystals with good performance. This method is of great significance to the treatment of saline wastewater in the chemical and metallurgical fields.

Summary: This study investigates riverine nutrient and total suspended solids (TSS) flux in six major Arctic rivers, showing significant variations in component concentrations and fluxes between seasons. The active layer thickness is positively correlated with annual riverine exports, suggesting that permafrost degradation accelerates the transport of carbonate, nitrogen, and phosphorus into rivers. Riverine exports play a crucial role in both Arctic terrestrial and marine ecosystems, and are expected to increase with permafrost degradation.

Summary: This study investigated the effects of environmental conditions on the presence and abundance of naturally occurring histamine-producing bacteria in the northern Gulf of Mexico. The results showed that HPB abundance and species composition are influenced by ambient temperature and salinity, with variations among different HPB species.

Summary: Using data collected in two cruises in summer 2019 and winter 2020, this study examines the variability in nutrients and chlorophyll concentrations in the southern-central Arabian Gulf and identifies the driving mechanisms. The results reveal differences in nutrient and chlorophyll concentrations between seasons, with higher concentrations in summer. Summer thermal stratification and intrusion of fresher surface water from the Arabian Sea contribute to the development of a hypoxic zone and increased nutrient concentrations. Winter cooling results in lower chlorophyll concentrations due to nutrient depletion caused by downwelling of dense water.

Summary: Brine seeps are extreme marine ecosystems that provide insights into the behavior of trace elements and rare earth elements, which are essential for microbial life. The study of carbonates formed at these sites reveals the involvement of deep brine fluids and mineral-water reactions in the precipitation process, impacting the distribution of trace metals and their role in microbial metabolisms.

Summary: This study investigated the temporal and spatial patterns of microphytobenthos (MPB) in a Pacific Northwest estuary with complex environmental gradients. The research found that MPB biomass and diatom assemblage composition varied between sites and seasons, with different relationships with environmental variables. Despite the complexity in understanding these relationships, the study suggests that tidal flat diatoms can serve as indicators of estuarine environmental conditions.

Summary: Groundwater discharge rates and nutrient input were quantified using the 222Rn mass balance model in ten lakes in the Badain Jaran Desert. The results showed a positive correlation between 222Rn activity and lake water depth, indicating the presence of groundwater discharge areas. The annual mean groundwater discharge amount received by lakes in the entire BJD was estimated to be (5.6 +/- 0.7) x 107 m3/a, with significant inputs of dissolved inorganic nitrogen, phosphorus, and silicon.

Summary: This paper reviews the application of salinity thresholds in Environmental Impact Statements (EIS) in Spanish desalination plants. It found that earlier thresholds were lower than scientific recommendations, leading to increased energy consumption and dilution ratios. The paper recommends unifying thresholds based on the best available scientific evidence to reduce energy-economic costs.

Summary: In Mexico, the discharge of 16 rivers into the Gulf of Mexico contributes to the seasonal variations in phytoplanktonic primary production. This study used new simulated flow and nutrient data to model the impact of these rivers on the Gulf's ecosystem. The model successfully reproduced the seasonal dynamics of primary production in the Gulf based on satellite images and previous studies.

Summary: This study quantified the impacts of tropical cyclones on water discharge and suspended sediment discharge in two small mountainous rivers in South China. The results showed that tropical cyclones significantly increased both water discharge and suspended sediment discharge in July and August. The findings suggest that with increasing tropical cyclone events due to global climate change, the mountainous rivers in South China will experience greater impacts on sediment discharge and water discharge.

Summary: Microplastics in marine ecosystems serve as microhabitats for diverse toxic plankton species, including viable resting cysts of dinoflagellates. The diversity of plankton communities on the plastisphere is influenced by anthropogenic factors. This study highlights the importance of plastics as vectors for the transport of harmful opportunistic species in the marine environment.

Summary: The Barents Sea, as the largest Arctic shelf region, plays a vital role in supporting commercial fisheries. The ecosystem of this region is significantly influenced by both warm Atlantic Water (AW) and cold Arctic Water (ARW), resulting in distinct frontal zones. This study found that copepod populations, particularly herbivorous copepods, were most abundant and productive in the Polar Front, as well as in the eastern frontal zones. The geographic positions of sampling stations, depth, and chlorophyll a concentration were identified as the main factors influencing copepod biomass and production.
