Winter post-droughts amplify extreme nitrate concentrations in German rivers

Hydrological extremes can affect nutrient export from catchments to streams, posing a threat to aquatic ecosystems. In this study, we investigated the effects of hydrological drought on nitrate concentrations in the streamflow of 182 German catchments from ...

Soil warming alters tree water use and canopy stomatal conductance in a mixed subtropical forest

Charlotte Grossiord, Christoph Bachofen

As air temperature and vapor pressure deficit (VPD) increase continuously, forests are losing more water through evapotranspiration, with large consequences for local and global hydrological cycles. In regions with high vegetation cover, soil warming can b ...

Linking Soil Structure, Hydraulic Properties, and Organic Carbon Dynamics: A Holistic Framework to Study the Impact of Climate Change and Land Management

Sara Bonetti

Climate change and unsustainable land management practices have resulted in extensive soil degradation, including alteration of soil structure (i.e., aggregate and pore size distributions), loss of soil organic carbon, and reduction of water and nutrient h ...

Accounting for foliar gradients in Vc(max) and J(max) improves estimates of net CO2 exchange of forests

Christoph Bachofen

Vertical gradients in the canopy represent a major challenge for scaling from foliar photosynthesis to ecosystem-level CO2 fluxes. We tested whether accounting for independent gradients of carboxylation capacity (Vc(max)) and photosynthetic electron transp ...

Vegetation Drastically Reduces Wind Erosion: An Implementation of the RWEQ in the Mongolian Gobi Steppe

Charlotte Gisèle Weil

Soil loss prevention is an important ecosystem service for protecting human and environmental health. Using spatiotemporal climate and environmental data of the Eastern Gobi Steppe, a region missing from previous studies of Mongolian wind-based soil erosio ...

Life cycle environmental assessment of retaining walls in unsaturated soils

Alessio Ferrari, Gianluca Speranza

Retaining structures above groundwater level support soils that are usually in a state of partial saturation and subject to the actions of atmospheric agents. The current design approach considers the possible extremes of soil conditions - either totally d ...

Microbes support enhanced nitrogen requirements of coral holobionts in a high CO 2 environment

Nils Rädecker, Gabriela Hannah Holligan Perna

Ocean acidification is posing a threat to calcifying organisms due to the increased energy requirements of calcification under high CO2 conditions. The ability of scleractinian corals to cope with future ocean conditions will thus depend on their ability t ...

Highly Variable and Non-complex Diazotroph Communities in Corals From Ambient and High CO2 Environments

Nils Rädecker, Gabriela Hannah Holligan Perna

The ecological success of corals depends on their association with microalgae and a diverse bacterial assemblage. Ocean acidification (OA), among other stressors, threatens to impair host-microbial metabolic interactions that underlie coral holobiont funct ...

Dion-Jacobson and Ruddlesden-Popper double-phase 2D perovskites for solar cells

Bowen Yang, Yang Liu, Chen Li, Xin Guo, Sajjad Ahmad

Dion-Jacobson (DJ) phase and Ruddlesden-Popper phase 2D perovskites have been, individually, demonstrated to be more stable than 3D counterparts for perovskite solar cells (PSCs). In order to further improve the efficiency and stability of 2D PSCs, we here ...

Shift in plant-soil interactions along a lakeshore hydrological gradient

Alexandre Buttler, Luca Bragazza, Mathieu Raymond Santonja, Wenjuan Feng

Wetlands occupy the transitional zone between aquatic and terrestrial systems. Hydrological conditions have significant influence on wetland plant communities and soil biogeochemistry. However, our knowledge about plant-soil interactions in wetlands along ...

Greater Contribution From Agricultural Sources to Future Reactive Nitrogen Deposition in the United States

Athanasios Nenes, Shuai Shao

Many sensitive ecosystems in areas protected for biodiversity conservation in the United States suffer from exposure to excess reactive nitrogen (Nr) released by fossil fuel combustion and agricultural practices and deposited onto the land surface and wate ...

High‐resolution spatial sampling identifies groundwater as driver of CO 2 dynamics in an Alpine stream network

Tom Ian Battin, Amber Joy Ulseth, Asa Lovisa Viktoria Horgby, Marta Boix Canadell

Inland waters are major sources of CO2 to the atmosphere. The origin of this CO2 is often elusive, especially in high‐altitude streams that remain poorly studied at present. Here we study the spatial and seasonal variations in streamwater CO2, its potentia ...

Model of crop growth, water flow, and solute transport in layered soil

David Andrew Barry, Jiancheng Yang

Agro-ecohydrological models are essential for managing scarce water resources and ensuring crop productivity. Here, a one-dimensional agro-ecohydrological model, LAWSTAC, capable of simulating water and solute transport in layered soil coupled with crop gr ...

Dynamics and potential drivers of CO2 concentration and evasion across temporal scales in high-alpine streams

Tom Ian Battin, Asa Lovisa Viktoria Horgby, Nicolas Thomas Georges Escoffier, Luis Gómez Gener

Carbon dioxide (CO2) evasion from streams greatly contributes to global carbon fluxes. Despite this, the temporal dynamics of CO2 and its drivers remain poorly understood to date. This is particularly true for high-altitude streams. Using high-resolution t ...

Spatiotemporal Drivers of CO2 Dynamics and Evasion Fluxes from Mountain Streams

Asa Lovisa Viktoria Horgby

Inland waters are key components of the global carbon cycle, emitting a substantial amount of carbon dioxide (CO2) to the atmosphere. Climate change and global warming affect mountain catchments significantly, leading to glacier retreat and changing precip ...

Full-scale in-situ tests on energy piles: Head and base-restraining effects on the structural behaviour of three energy piles

Melis Sütman

Energy piles, due to their dual roles, are exposed to temperature change throughout their life time, which may cause axial displacements, additional axial stresses and changes in the shaft resistance along their lengths. The extent of these effects highly ...
