Multi-year time series of daily solute and isotope measurements from three Swiss pre-Alpine catchments
Time series analyses of solute concentrations in streamwater and precipitation are powerful tools for unraveling the interplay of hydrological and biogeochemical processes at the catchment scale. While such datasets are available for many sites around the ...
Nature Portfolio2024X-ray chemical imaging for assessing redox microsites within soils and sediments
Redox reactions underlie several biogeochemical processes and are typically spatiotemporally heterogeneous in soils and sediments. However, redox heterogeneity has yet to be incorporated into mainstream conceptualizations and modeling of soil biogeochemist ...
Frontiers Media Sa2024Treeline displacement may affect lake dissolved organic matter processing at high latitudes and altitudes
Climate change induced shifts in treeline position, both towards higher altitudes and latitudes induce changes in soil organic matter. Eventually, soil organic matter is transported to alpine and subarctic lakes with yet unknown consequences for dissolved ...
Nature Portfolio2024Towards a metabolic theory of catchments: scaling of water and carbon fluxes with size
Sara Bonetti, Francesca Bassani
Allometric scaling relations are widely used to link biological processes in nature. They are typically expressed as power laws, postulating that the metabolic rate of an organism scales as its mass to the power of an allometric exponent, which ranges betw ...
2024Consider the Anoxic Microsite: Acknowledging and Appreciating Spatiotemporal Redox Heterogeneity in Soils and Sediments
Reduction-oxidation (redox) reactions underlie essentially all biogeochemical cycles. Like most soil properties and processes, redox is spatiotemporally heterogeneous. However, unlike other soil features, redox heterogeneity has yet to be incorporated into ...
AMER CHEMICAL SOC2023Surface water and groundwater interactions in salt marshes and their impact on plant ecology and coastal biogeochemistry
Salt marshes are highly productive intertidal wetlands providing important ecological services for maintaining coastal biodiversity, buffering against oceanic storms, and acting as efficient carbon sinks. However, about half of these wetlands have been los ...
2022Soil protist function varies with elevation in the Swiss Alps
Nicolas Jean Philippe Guex, Edward Mitchell, Enrique Lara, Aline Buri
Protists are abundant and play key trophic functions in soil. Documenting how their trophic contributions vary across large environmental gradients is essential to understand and predict how biogeochemical cycles will be impacted by global changes. Here, u ...
2022The Biogeochemical Legacy of Arctic Subglacial Sediments Exposed by Glacier Retreat
During past periods of advance, Arctic glaciers and ice sheets overrode soil, sediments, and vegetation and buried significant stores of organic matter (OM); these glaciers are now shrinking rapidly due to climate warming. Little is known about the biogeoc ...
2022Towards an improved understanding of biogeochemical processes across surface-groundwater interactions in intermittent rivers and ephemeral streams
Luis Gómez Gener, Oleksandra Shumilova
Surface-groundwater interactions in intermittent rivers and ephemeral streams (IRES), waterways which do not flow year-round, are spatially and temporally dynamic because of alternations between flowing, non-flowing and dry hydrological states. Interaction ...
