Biotic and Abiotic Constraints on the Decomposition of Fagus sylvatica Leaf Litter Along an Altitudinal Gradient in Contrasting Land-Use Types

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Thomas Spiegelberger, Robert Thomas Edmund Mills

Climate change can affect the process of carbon cycling and leaf litter decomposition in multiple ways, both directly and indirectly, though the strength and direction of this relationship is often context dependent. In this experiment, we followed decompo ...

Spatial variability of soil phosphorus in the Fribourg canton, Switzerland

Stéphane Joost, Nicolas Rossier

Phosphorus (P) is the second essential nutrient for plant growth but can become an ecological and economical concern in case of over-fertilization. Soil P dynamic is influenced by many parameters like soil physical-chemical properties and farming practices ...

No evidence of aquatic priming effects in hyporheic zone microcosms

Tom Ian Battin

The priming effect refers to quantitative changes in microbial decomposition of recalcitrant organic matter upon addition of labile organic matter and is a phenomenon that mainly has been reported and debated in soil science. Recently, priming effects have ...

Farm-Scale Tradeoffs Between Legume Use as Forage versus Green Manure: The Case of Canavalia brasiliensis

Claudia Rebeca Binder Signer

To support a sustainable increase in agricultural productivity, the multipurpose legume Canavalia brasiliensis was integrated as forage and green manure into the smallholder crop-livestock system of the Nicaraguan hillsides. Through on-farm trials, sur- ve ...

Influence of root characteristics and soil variables on the uprooting mechanics of Avena sativa and Medicago sativa seedlings

Paolo Perona, Benoît Crouzy, Katharina Maria Edmaier, Paolo Burlando

The success of seedlings and rejuvenated woody debris growing on river bedforms depends on the resistance to uprooting by flow provided by their simple root architecture. Avena sativa and Medicago sativa seedlings were used in flume experiments as prototyp ...

Raindrop Impact on Saturated Soil

David Andrew Barry, Mohsen Cheraghi

Soil erosion is an important environmental phenomenon that causes many side effects such as reduction of soil productivity in the fields and transportation of pollutants to non-contaminated areas. Extensive well designed and controlled flume experiments in ...

Tidal influence on soil conditions in an intertidal creek-marsh system

David Andrew Barry

To understand better how tides affect the soil conditions of salt marshes, pore-water flow in a modeled 3-D creek-marsh system was simulated under the influence of both monochromatic and spring-neap tides. In analyzing the simulation results, we examined s ...

Mobile uranium(IV)-bearing colloids in a mining-impacted wetland

Rizlan Bernier-Latmani, Manon Frutschi, Elena Suvorova Buffat, Yuheng Wang

Tetravalent uranium is commonly assumed to form insoluble species, resulting in the immobilization of uranium under reducing conditions. Here we present the first report of mobile U(IV)-bearing colloids in the environment, bringing into question this commo ...

Modelling of groundwater-vegetation interactions in a tidal marsh

David Andrew Barry

Wetting and drying due to tidal fluctuations affect soil conditions and hence plant growth in tidal marshes. Here, a coupled one-dimensional model was developed to simulate interacting groundwater flow and plant growth in these wetlands. The simulation res ...

Light Availability Prevails Over Soil Fertility and Structure in the Performance of Asian Knotweeds on Riverbanks: New Management Perspectives

Thomas Spiegelberger

Asian knotweeds (Fallopia spp.) are considered one of the world's most invasive species. Restoring habitats dominated by these exotic species requires a better understanding of the importance of abiotic factors controlling the invasive knotweeds performanc ...
