Short summary
This study presents one of the few studies to simultaneously measure all three major greenhouse gases across multiple shallow coastal bays in the Baltic Sea. Our findings reveal that these bays are highly variable and significant sources of greenhouse gases, with fluxes strongly influenced by bay characteristics and seasonal variation. By linking concentrations to environmental drivers, our work provides novel insights into overlooked but important components of coastal greenhouse gas budgets.

The Soil Warming to Depth Data Integration Effort (SWEDDIE) synthesizes data from deep soil warming experiments around the world (n = 23), offering new insight into warming responses of both surface and subsoils. We demonstrate that variation in soil warming with depth is driven largely by warming methodology, while soil moisture changes due to warming differ by ecosystem. This work serves a foundation for future syntheses with SWEDDIE.

Short summary
Seagrass meadows are hotspots for biodiversity and productivity, and planting seagrass is proposed as a tool for mitigating biodiversity loss and climate change. We assessed seagrass planted in different years and found that benthic oxygen and carbon fluxes increased as the seabed developed from bare sediments to a mature seagrass meadow. This increase was partly linked to the diversity of colonizing algae which increased the light-use efficiency of the seagrass meadow community.

Our research highlights the concerning impact of rising carbon dioxide levels on coastal areas. To better understand these changes, we've established an observation network in France. By deploying pH sensors and other monitoring equipment at key coastal sites, we're gaining valuable insights into how various factors, such as freshwater inputs, tides, temperature, and biological processes, influence ocean pH.

In order to gain the first mechanistic insight into warming effects and litter breakdown dynamics across whole-soil profiles, we used a unique field warming experiment and standardized plant litter to investigate the degree to which rising soil temperatures can accelerate belowground litter breakdown in coastal wetland ecosystems. We found warming strongly increases the initial rate of labile litter decomposition but has less consistent effects on the stabilization of this material.

A dynamic vegetation model, designed to estimate potential impacts of early vascular vegetation, namely, lycopsids, on the biogeochemical cycle at a local scale. Lycopsid Model (LYCOm) estimates the productivity and physiological properties of lycopsids across a broad climatic range along with natural selection, which is then utilized to adjudge their weathering potential. It lays the foundation for estimation of their impacts during their long evolutionary history starting from the Ordovician.

Short summary
We examined if sea-level rise and plant genotype interact to affect soil microbial functioning in a mesocosm experiment using two genotypes of a dominant salt-marsh grass characterized by differences in flooding sensitivity. Larger variability in microbial community structure, enzyme activity, and litter breakdown in soils with the more sensitive genotype supports our hypothesis that effects of climate change on soil microbial functioning can be controlled by plant intraspecific adaptations.

Editorial statement
Coastal marshes play an important role in climate regulation and ecosystem services. This study provides the first large-scale assessment of carbon storage in Nordic coastal marshes, a region currently underrepresented in global blue carbon datasets. It shows how grazing management and environmental conditions jointly influence carbon storage and vegetation structure.
Coastal marshes play an important role in climate regulation and ecosystem services. This study...
Short summary
Coastal marshes store high amounts of carbon but remain understudied in Nordic region. We measured organic carbon stored in plants and soil across grazed and ungrazed marshes along environmental gradients. Livestock grazing limited reed dominance, reduced aboveground carbon and altered roots allocation. Soil carbon was mainly controlled by soil properties rather than grazing at large scale. Our results show how grazing and environmental conditions jointly shape carbon storage in coastal marshes.
Coastal marshes store high amounts of carbon but remain understudied in Nordic region. We...
