Summary: The study reveals that subtropical mangrove estuaries in southern Texas play a crucial role in methane cycling, influenced by tidal processes, amplitude, and topographic characteristics. Normally, these mangroves are a weak source of methane emissions, but after a severe cold-freezing event, the mangrove dieback resulted in significantly elevated methane emissions. This study highlights the importance of management considerations for blue carbon projects in vulnerable areas.

Summary: The study investigates the mobility and behavior of tellurium (Te) in the environment by comparing two Te-enriched mining sites in Mexico. The findings suggest that Te is released to the environment through the dissolution of primary Te minerals and undergoes dynamic cycling. The study also reveals the presence of secondary Te minerals and their association with microbial processes.

Summary: Climate change may increase future atmosphere evaporative demand and intensify local water stress. The study shows that the future change in agricultural irrigation water use is determined by both climate change and crop responses to atmospheric CO2 concentration. Adjusting crop patterns can potentially alleviate local water stress.

Summary: This study found that the death of mangrove forests after extreme weather events led to a significant decrease in soil carbon stock and a substantial loss of iron. These impacts can have long-term effects on the ability of mangrove forests to immobilize pollutants and sequester carbon.

Summary: This study investigates potassium isotope fractionation within a soil-plant system in humid and arid environments on Kohala Mountain, Hawai‘i. The results show that within the same plant, different tissues have varying potassium isotopic compositions, and isotopic differences are observed between soils of different moisture levels. The study suggests that processes such as K redistribution during intra-plant circulation and K uptake at the root-soil interface contribute to potassium isotope fractionation.

Summary: This study suggests that by increasing the marginal value of groundwater extraction for irrigation, groundwater extraction volumes can be reduced in semi-arid regions under different climate scenarios, with a resulting decrease in regional net benefits of agricultural production.

Summary: Plant roots are the primary source of soil organic carbon and play a crucial role in supporting microbial growth in the rhizosphere. Climate change factors can affect root-microbial interactions and impact carbon dynamics in the soil. Experimental evidence shows that warming and precipitation changes strengthen root controls over litter decomposition in semi-arid grasslands, with precipitation having a significant impact on microbial activities.

Summary: Understanding the impacts of climate change and human activities on ecosystems is crucial. This study investigated the effects of climate variation and human activities on major indicators of ecosystem functions and conditions in Xinjiang, a typical arid and semi-arid region in China. The results show that human activities have a significant influence on ecosystem indicators in arid and semi-arid zones.

Summary: This study focuses on the replenishment of groundwater in a semi-arid region in Tanzania, showing that focused recharge from ephemeral stream discharges is critical. Groundwater level rises correspond better to pulses of stream discharge from intensive rainfall than from seasonal rainfall. Stable isotope ratios of O and H indicate similarities between groundwater and ephemeral streamflow, both linked to intensive daily rainfall.

Summary: Empirical soybean breeding has improved yield in arid and semi-arid areas of China. This study identified key traits in successful commercial soybean cultivars, such as shortened time to flowering and extended seed filling period, fewer pods but increased seed weight and number per pod, increased harvest index, and reduced water use.

Summary: This study investigates the variations of dissolved inorganic carbon (DIC), water partial pressure of CO2 (pCO(2)), and water-air CO2 fluxes in a tidal creek of a temperate coastal lagoon. The results show that the surface water of the lagoon is slightly oversaturated in CO2 compared to the atmosphere, and the subsurface water pCO(2) values are controlled by temperature and biological/tidal advection effects. High-resolution pCO(2) records reveal that biological activity, tidal flat advection, and porewater pumping contribute to the variations of water pCO(2) and carbonate chemistry. The alkalinity-salinity relationship suggests a net production of alkalinity in the lagoon due to benthic carbonate dissolution and anaerobic degradation of organic matter. During flooding, daytime pCO(2) values are lower than nighttime pCO(2) values due to photosynthesis, while during ebbing, daytime pCO(2) values are higher than nighttime pCO(2) values due to heating. The lagoon waters are a relatively weak CO2 source to the atmosphere compared to other estuarine and lagoon waters.

Summary: Total and dissolved concentrations of inorganic mercury (IHg) and methylmercury (MeHg) in water were analyzed in Adour Estuary. Factors such as sampling time and sample type were considered, and the results showed that the estuary has experienced historical anthropogenic contamination, but decreased emissions have led to reduced Hg concentrations. The concentrations of IHg and MeHg were influenced by suspended particulate matter and particulate organic carbon, with higher concentrations detected near specific discharge points.

Summary: The fluctuation of environmental conditions in estuaries drives the structure of microbial communities, which play a key role in ecosystem functioning. In this study, the microbial communities in the Adour Estuary were investigated using gene sequencing and chemical analysis. The results showed a strong seasonal organization and spatial distribution of microbial communities, influenced by biogeochemical parameters and micropollutants. Network analysis revealed specific modules linked to pollutant types, providing important insights into estuarine microbial ecology.
