Summary: Wetlands provide essential ecosystem services and are sensitive to changes in wetland hydrology. The study in west-central Florida investigated the sources of variation in wetland inundation and found that water levels and hydroperiods were affected by factors such as precipitation, groundwater extraction, and land development. Water conservation policies led to an increase in wetland water depths and longer hydroperiods, but some wetlands did not show signs of hydrological recovery. The study highlights the importance of recognizing the sensitivity of wetland inundation to groundwater extraction during periods of low precipitation.

Summary: Hydrologic processes play a critical role in the carbon processing and export in wetland ecosystems, especially in the transport and transformation of soil-derived dissolved organic matter (DOM). This study found that different soil horizons have distinct contributions to DOM transport in wetlands, with organic horizons being the most significant source. Understanding the behavior and impacts of DOM in wetland ecosystems, particularly in the context of climate change, is of great importance.

Summary: According to the research, it is predicted that global soil temperature will rise by the end of this century, affecting temperate forest regions. Increased soil temperature may lead to higher carbon dioxide release from these soils, causing positive feedback on climate change. However, there is limited research on the impact of temperature on dark carbon fixation rates.

Summary: Soil organic carbon sequestration is a promising method for mitigating climate change, and the formation of mineral-associated organic carbon (MAOC) plays a crucial role. Previous studies have suggested that the ability of soils to accumulate MAOC is limited by the amount of clay and silt particles. However, our analysis of soil samples from different land uses found that there was no detectable upper limit of MAOC content, challenging the notion that soil texture is the main limiting factor. Additionally, we observed a negative correlation between C content in the fine fraction and fine fraction content, further questioning the existing understanding of MAOC accumulation.

Summary: The rising atmospheric methane burden and the uncertainty surrounding its causes are the focus of this study. The researchers present a collection of new delta C-13(CH4) signatures for tropical wetlands and rice fields, which provide insights into isotopic variation and potential seasonal shifts. Long-term monitoring at two observatories in Bolivia and Botswana shows that biogenic methane sources, particularly wetlands, dominate the records. The findings suggest significant seasonal variation in tropical wetland delta C-13(CH4) signatures, highlighting the need to incorporate this variability into future global and regional models.

Summary: Mexican wetlands, which are important carbon stores in tropical wetland soils, are not included in global Earth system models. This review focuses on studying the carbon pools and sequestration in different types of wetlands in Mexico. It is found that swamps sequester more carbon in the soil compared to other wetland types, but they are not given sufficient attention in Mexican protection laws compared to mangroves. The carbon pools detected in mangroves, marshes, and flooded grasslands are statistically similar. Systematic data on carbon dynamics in tropical wetlands is needed for their incorporation into global carbon budgets.

Summary: Denitrification is an important process mediated by microorganisms that can be influenced by the presence of copper. This study found that adding trace amounts of copper enhanced the reduction rate of nitrous oxide (N2O) to nitrogen gas (N2) in wetland soils and stream sediments. A kinetic model showed that the presence of copper significantly increased the conversion of N2O to N2. The study also suggested that in some cases, the overall denitrification process is driven by abiotic reduction of nitrite (NO2-). These findings highlight the significance of copper in controlling denitrification in natural aquatic systems.

Summary: The role of soil organic carbon (SOC) sequestration as a 'win-win' solution to both climate change and food insecurity is critically examined in this article. The inclusion of SOC saturation in estimations significantly reduces the potential contribution of SOC sequestration to climate change mitigation, and the observed yield effects of increasing SOC are inconsistent. The article argues for a shift towards soil-smart agriculture that takes into account specific local conditions and quantifies multiple soil functions for land sustainability and food security.

Summary: Reduced tillage in organic farming can increase SOC stocks in surface layers, decrease them in intermediate layers, and increase them in deeper soil layers. The cumulative SOC stocks increased by 1.7% or 1.5 Mg ha-1 (0-50 cm, n = 9) and 3.6% or 4.0 Mg ha-1 (0-100 cm, n = 7) compared with ploughing. The estimated mean C sequestration rates were 0.09 and 0.27 Mg ha-1 yr-1, respectively.

Summary: The study found that both LECA and LS mineral aggregates significantly improved orthophosphate removal from water extracted from eutrophic lakes, especially when 75% LS was added to the LECA bed. However, it is not feasible to install a full-scale bed made of these mineral aggregates in real-life conditions due to the large required size.

Summary: The study indicates that shallow urban polluted reservoirs in tropical regions can be hotspot for CO2 and CH4 emissions, with nutrient-rich conditions leading to increased greenhouse gas emission. High concentrations of nutrients in the water column support the production of autotrophic biomass that contribute to CH4 emission. The findings highlight the importance of water quality improvement and eutrophication mitigation in highly urbanized reservoirs in tropical regions.

Summary: This study investigated the impact of hurricane Irma on mangrove functions, finding increased aboveground biomass and decreased soil carbon storage as a result. Mangrove swamps may have a feedback on climate change by losing their ability to store carbon in belowground pools. However, the study also showed that mangrove swamps remain resilient to tropical storms in the long term and can recover their carbon storage capacity in the years following a storm.

Summary: This study investigates the soil carbon dynamics in hydrologically altered mangrove swamps in Puerto Rico and finds that there are different patterns of carbon storage among sites with varying levels of disturbance. The results suggest that mangroves have the potential to retain their carbon storage capacities despite hydrologic alterations, but mass carbon storage within mangrove forests can be spatially variable in hydrologically altered conditions.

Summary: This study examined the long-term phosphorus retention in Stormwater Treatment Areas (STAs) and identified the factors influencing their performance. The results showed that the operational performance of STAs improved over time. There were notable differences among individual STAs, with the co-precipitation of phosphorus with calcium playing a critical role in one of the STAs. This highlights the complexity of phosphorus removal in STAs and the need for site-specific management strategies.

Summary: The biogeochemical response to different flow conditions within two parallel flow-ways in Everglades Stormwater Treatment Area (STA)-2 was studied. It was found that there was a gradual decrease in the total phosphorus (TP) concentration from inflow to outflow for both emergent aquatic vegetation (EAV) and submerged aquatic vegetation (SAV) dominated systems, with EAV showing a higher reduction rate. Significant increase in TP concentration was observed in the SAV system under no flow condition, possibly due to the production of particulate phosphorus (PP) through various mechanisms.
