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 ...

Long-term effects of crop succession, soil tillage and climate on wheat yield and soil properties

Mathieu Raymond Santonja, María Paula Sanginés De Cárcer

Climate change is increasing crop losses and yield variability with impacts for global food security. In this context, conservation agriculture appears as a potential solution to maintain crop productivity, soil fertility and environmental sustainability. ...

Integrating models across temporal and spatial scales to simulate landscape patterns and dynamics in mountain pasture-woodlands

Alexander Ludwig Johannes Peringer

Context Pasture-woodlands are semi-natural landscapes that result from the combined influences of climate, management, and intrinsic vegetation dynamics. These landscapes are sensitive to future changes in land use and climate, but our ability to predict t ...

A path to stable low-torque plasma operation in ITER with test blanket modules

Holger Reimerdes

New experiments in the low-torque ITER Q = 10 scenario on DIII-D demonstrate that n = 1 magnetic fields from a single row of ex-vessel control coils enable operation at ITER performance metrics in the presence of applied non-axisymmetric magnetic fields fr ...

Associative interplay of plant growth promoting rhizobacteria (Pseudomonas aeruginosa QS40) with nitrogen fertilizers improves sunflower (Helianthus annuus L.) productivity and fertility of aridisol

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Muhammad Saleem Arif, Muhammad Riaz

The environmental and economic impacts of chemical fertilizer have encouraged farmers to integrate them with organic materials, an important nutrient management strategy for sustainable agriculture production. In the present study, we conducted field exper ...

Drought-induced shifts in plants traits, yields and nutritive value under realistic grazing and mowing managements in a mountain grassland

Alexandre Buttler, Constant Signarbieux, Thomas Spiegelberger, Claire Emilie Deléglise

Extreme drought events can dramatically impact grassland ecosystems, causing potential loss of forage production for livestock in temperate grasslands. However, knowledge of drought effects on forage production, nutritive value and plant community stabilit ...

Cadmium accumulation in six common plant species associated with soils containing high geogenic cadmium concentrations at Le Gurnigel, Swiss Jura Mountains

François Gillet

The uptake of cadmium (Cd) was analyzed for six different perennial plant species growing in a wooded pasture of the Swiss Jura Mountains, where the soils are geogenically enriched in Cd (4.58 mg.kg(-1) on average (n = 36); maximal value: 16.3 mg.kg(-1)). ...

Optimizing Carbon Storage Within a Spatially Heterogeneous Upland Grassland Through Sheep Grazing Management

Charlotte Vandenberghe

Livestock grazing is known to influence carbon (C) storage in vegetation and soil. Yet, for grazing management to be used to optimize C storage, large scale investigations that take into account the typically heterogeneous distribution of grazers and C acr ...

Hydrologic Variability Affects Invertebrate Grazing on Phototrophic Biofilms in Stream Microcosms

Andrea Rinaldo, Enrico Bertuzzo, Tom Ian Battin, Lorenzo Mari, Serena Ceola, Gianluca Botter

The temporal variability of streamflow is known to be a key feature structuring and controlling fluvial ecological communities and ecosystem processes. Although alterations of streamflow regime due to habitat fragmentation or other anthropogenic factors ar ...

Dynamics of Forage Production in Pasture-woodlands of the Swiss Jura Mountains under Projected Climate Change Scenarios

Alexandre Buttler, Konstantin Svetlozarov Gavazov, François Gillet, Thomas Spiegelberger, Alexander Ludwig Johannes Peringer

Silvopastoral systems of the Swiss Jura Mountains serve as a traditional source of forage and timber in the subalpine vegetation belt, but their vulnerability to land use and climate change puts their future sustainability at stake. We coupled experimental ...

Hydrologic Drivers and Controls of Stream Ecological Processes

Serena Ceola

The temporal variability of streamflows is a key feature structuring and controlling ecological communities and ecosystem processes. The magnitude, frequency and predictability of streamflows, and thus of velocity and near-bed shear stress fields, control ...

Effect of dung deposition on small-scale patch structure and seasonal vegetation dynamics in mountain pastures

Alexandre Buttler, Charlotte Vandenberghe, François Gillet

Cattle activity greatly influences plant species composition and biomass production of grassland ecosystems. Dung deposition by cattle together with grazing and trampling can be considered as one of the important factors driving vegetation dynamics in past ...

Short-term effects of cattle browsing on tree sapling growth in mountain wooded pastures

Alexandre Buttler, Charlotte Vandenberghe, François Frelechoux

Browsing by livestock has been identified as an important factor preventing tree regeneration in wooded pastures. Two field experiments were performed to investigate the effects of cattle browsing on tree sapling growth in a mountainwooded pasture. Two siz ...

Nurse plants, tree saplings and grazing pressure: decreasing facilitation along a biotic environmental gradient

Charlotte Vandenberghe

Current conceptual models predict that an increase in stress shifts interactions between plants from competitive to facilitative; hence, facilitation is expected to gain in ecological importance with increasing stress. Little is known about how facilitativ ...

Modern pollen assemblages from grazed vegetation in the western Pyrenees, France: a numerical tool for more precise reconstruction of past cultural landscapes

Alexandre Buttler

Modern pollen assemblages from grazed vegetation in the Pyrenees Mountains (France) were studied with the aim of providing a calibrated model for reconstructing past pastoral activities. The modern analogues were selected to cover the major gradients of gr ...

The influence of cattle activity on tree regeneration in wood-pastures

Charlotte Vandenberghe

Wood-pastures are semi-natural, highly biodiverse systems maintained by traditional extensive agriculture. They are used for grazing and timber. The shifting mosaics of grassland, shrub thickets and woodland patches in these systems are driven by large her ...

Spatial and seasonal patterns of cattle habitat use in a mountain wooded pasture

Alexandre Buttler, François Gillet, Jean-Michel Gobat

Management-oriented models of cattle habitat use often treat grazing pressure as a single variable summarizing all cattle activities. This paper addresses the following questions: How does the spatial pattern of cattle effects vary between cattle activitie ...
