On the use of leaf water to determine plant water source: A proof of concept
Source water apportionment studies using the dual isotopes of oxygen and hydrogen have revolutionized our understanding of ecohydrology. But despite these developments-mostly over the past decade-many technical problems still exist in terms of linking xyle ...
WILEY2021Species identity, rather than species mixtures, drives cover crop effects on nutrient partitioning in unfertilized agricultural soil
Alexandre Buttler, Pierre Rémi Mariotte, Mathieu Raymond Santonja, Lucas Georges Jean-Paul Freund
Aims Previous cover crop studies mainly focused on the links between plant uptake and soil fertility, and there is a clear knowledge gap regarding the role of microbes in these processes. Our aim was then to better understand the effects of plant mixtures ...
SPRINGER2020Regional investigation of spatial-temporal variability of soil magnesium - a case study from Switzerland
Stéphane Joost, Luca Bragazza, Clément Levasseur
Magnesium (Mg) is an essential element for plant growth and human health. Its availability and spatial distribution in soils depends on a wide variety of intrinsic and extrinsic factors. Understanding how Mg availability changes in space and time is crucia ...
2020Shift 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 ...
ELSEVIER2020Methylation of arsenic by single-species and soil-derived microbial cultures
Arsenic (As) is simultaneously a ubiquitous and a toxic element. Arsenic is subject to bio-transformations catalyzed by microorganisms constituting the As biogeochemical cycle. The primordial Earth was devoid of oxygen, exposing life to the highly mobile a ...
EPFL2020Genetic variation and evolutionary history of a mycorrhizal fungus regulate the currency of exchange in symbiosis with the food security crop cassava
Most land plants form symbioses with arbuscular mycorrhizal fungi (AMF). Diversity of AMF increases plant community productivity and plant diversity. For decades, it was known that plants trade carbohydrates for phosphate with their fungal symbionts. Howev ...
2020Persistent decay of fresh xylem hydraulic conductivity varies with pressure gradient and marks plant responses to injury
Defining plant hydraulic traits is central to the quantification of ecohydrological processes ranging from land-atmosphere interactions, to tree mortality and water-carbon budgets. A key plant trait is the xylem specific hydraulic conductivity (Kx), that d ...
2020Genetically Different Isolates of the Arbuscular Mycorrhizal Fungus Rhizophagus irregularis Induce Differential Responses to Stress in Cassava
Water scarcity negatively impacts global crop yields and climate change is expected to greatly increase the severity of future droughts. The use of arbuscular mycorrhizal fungi (AMF) can potentially mitigate the effects of water stress in plants. Cassava i ...
FRONTIERS MEDIA SA2020Composition and superposition of alluvial deposits drive macro-biological soil engineering and organic matter dynamics in floodplains
Claire Guenat, Pascal Turberg, Rodolphe Schlaepfer, Renée-Claire Le Bayon, Andreas Cedric Schomburg
Soil structure formation in alluvial soils is a fundamental process in near-natural floodplains. A stable soil structure is essential for many ecosystem services and helps to prevent river bank erosion. Plants and earthworms are successful soil engineering ...
2019Nutrient limitations induced by drought affect forage N and P differently in two permanent grasslands
Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra, Claire Emilie Deléglise
Drought events can strongly affect ecosystem functioning by modifying relationship between plants, microbes and soil chemistry, with consequent impacts on nutrient cycling. However, the potential impacts of a soil moisture reduction on the nitrogen (N) and ...
