Summary: We investigated the succession of soil microbial communities in newly constructed salt marshes using 16S rRNA amplicon sequences. The alpha diversity of subsurface horizons recovered to reference levels within 3 years, while alpha diversity in surface soils remained unchanged. Microbial community succession was faster in surface soils and slower in subsurface horizons. We found important taxa driving the trajectories towards reference conditions and observed co-development of sulfide and methane removal metabolisms in marsh soils.

Summary: The resilience of communities has become a major goal in policy and practice, with laws requiring climate-related hazard vulnerability assessments in master plan updates. Quantifying community resilience is crucial to measure preparedness and enhance capacity to endure disasters. Two approaches, community and infrastructure resilience, are being pursued, and a hybrid approach combining both is proposed.

Summary: Permafrost-affected soils in the Arctic store a significant amount of soil organic carbon, which becomes vulnerable to microbial decomposition with PF warming. This study showed that long-term warming led to continuous greenhouse gas production, along with a decrease in major metabolic pathway genes and an increase in carbohydrate-active enzyme classes, indicating a shift in organic matter degradation processes.

Summary: Coastal marshes in the Northeastern U.S. are converting to open water due to accelerated sea level rise and historic impacts. The installation of tidal channel extension features, or runnels, has shown promise in promoting vegetation recolonization and reducing water levels. However, there is limited data available to support its advisability.

Summary: Climate change and erosion from agricultural areas can cause increased drying periods and bedform migration of riverbeds. Sediment drying and bedform migration can independently stress the microbial community residing in the riverbed. The recovery process of the microbial community after exposure to these stressors varies in terms of function and structure, with different recovery times for community respiration and gross primary production. The impacts of sediment drying and bedform migration on microbial function and structure can persist for several months, and consecutive stress events combined with seasonal effects may hinder the recovery process, causing severe alterations to the microbial community.

Summary: This study shows that tidal freshwater marsh plant and animal communities are vulnerable to long-term salinity changes but resilient to short saline pulses. While saline pulses did not impair most ecosystem functions, the decline of a single species in the pulse treatment was associated with reduced marsh accretion and no elevation gain, which are crucial for wetland survival in an era of rising seas.

Summary: Climate change and land-use intensification pose increasing threats to biodiversity. In a field-scale grassland experiment, we tested the combined effects of climate change and land-use intensification on arthropod biodiversity. We found that climate change reduced arthropod abundance, while land-use intensification reduced overall community abundance and altered species composition. These changes will have profound consequences for ecosystem functioning under future environmental conditions.

Summary: Global environmental change, including increases in soil temperatures and alterations in precipitation patterns, affects soil biota in natural and managed systems. In arable systems, interactions of soil warming and altered precipitation amount and frequency impact soil conditions and health, with warming increasing nematode density and reduced precipitation frequency decreasing it. Different nematode groups respond differently to warming and precipitation changes, highlighting the importance of considering these interactions in agroecosystem management under climate change.

Summary: The study found that restored salt marshes had lower elevation but greater plant biomass, ecosystem production, respiration, and CO2 exchange compared to natural references. Respiration rates in aboveground biomass and soil were also higher in restored marshes. This suggests that well-restored salt marshes may enhance carbon sequestration rates and extend marsh survival.

Summary: Nitrogen pollution poses a significant threat to coastal water quality globally, leading to an increasing demand for governmental regulations and marine policy to address nitrogen pollution. In situ nitrogen reduction practices, including the potential contributions of coastal bivalve shellfish to enhanced denitrification, are being considered as complementary management approaches. However, the incorporation of bivalve-enhanced denitrification into water quality policy remains limited, despite evidence suggesting its effectiveness in nitrogen removal.

Summary: Over the past two decades, the importance of terrestrial plants in regulating silicon cycling has been recognized. Despite low silicon concentrations, mangroves, as highly productive tropical coastal ecosystems, appear to play a crucial role in silicon cycling. The findings suggest that mangroves could be considered as hot spots for silicon cycling in tropical coastal systems.

Summary: The productivity and life-supporting capacity of ecosystems depend on access to reactive nitrogen. However, long-term records show that nitrogen availability is declining in many regions of the world. Global changes, such as elevated atmospheric carbon dioxide levels and rising temperatures, are affecting the balance between ecosystem nitrogen supply and demand. This decline in nitrogen availability is limiting primary productivity and reducing the quality of herbivore diets in many ecosystems. We outline the current state of knowledge about declining nitrogen availability and propose actions to address this emerging challenge.

Summary: Seagrasses are important for mitigating climate change, but their actual carbon sequestration capacity also depends on methane and nitrous oxide fluxes. This study observed methane and nitrous oxide fluxes in seagrass meadows and found that the systems were small net sources of these gases to the atmosphere. The sediments were not likely the source of these gases emitted to the atmosphere.

Summary: The impact of coastal acidification on sediment N2O and CH4 fluxes is still unclear. This study exposed temperate estuarine sediments to moderate and extreme acidification and found that low pH had a strong effect on greenhouse gas fluxes, but the response varied depending on the site and nitrogen loading. Sediments from high-nitrogen loading site showed increased N2O fluxes and decreased CH4 fluxes under acidification, while sediments from low-nitrogen loading site exhibited decreased N2O fluxes and both decreased and increased CH4 fluxes. This study highlights the dynamic response of sediment N2O and CH4 fluxes to low pH and emphasizes the need for a deeper understanding of coastal acidification impacts on sediment biogeochemistry.

Summary: Nitrogen fixation is a crucial process that links the atmospheric nitrogen pool to the biosphere. Despite the prevailing belief that nitrogen fixation only occurs to meet nitrogen demands, recent research has shown that sediment nitrogen fixation can take place even in nitrogen-rich coastal environments. This challenges the traditional view of nitrogen fixation as solely a relief mechanism for nitrogen limitation. In this article, the author proposes that coastal sediments are actually ideal environments for nitrogen fixation and presents ideas on why this is the case. The goal is to encourage further research on the dynamics and composition of sediment nitrogen fixation.
