Invasive palms have more efficient and prolonged CO2 assimilation compared to native sub-Mediterranean vegetation

Charlotte Grossiord, Christoph Bachofen, Thibaut Michel Georges Juillard, Janisse Deluigi, Marco Conedera

In sub-Mediterranean ecosystems, shade-tolerant broadleaf evergreens, especially the invasive Trachycarpus fortunei, are spreading uncontrollably in the forest understorey, impeding the regeneration of the native deciduous woody vegetation. Most invasive s ...

Persistent decay of fresh xylem hydraulic conductivity varies with pressure gradient and marks plant responses to injury

Sara Bonetti, Dani Or

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 ...

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 ...

Herbaceous Angiosperms Are Not More Vulnerable to Drought-Induced Embolism Than Angiosperm Trees

Alexandre Buttler, Hervé Cochard, Constant Signarbieux

The water transport pipeline in herbs is assumed to be more vulnerable to drought than in trees due to the formation of frequent embolisms (gas bubbles), which could be removed by the occurrence of root pressure, especially in grasses. Here, we studied hyd ...

Combining UAV-imagery and machine learning for wildlife conservation

Semi-arid savannas are endangered by changes in the fragile equilibrium between rainfalls, fires and grazing pressure exerted by wildlife or cattle. To avoid bush encroachment and the decline of perennial grass, land managers must pay attention to keep the ...

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)). ...

Seasonal small-scale spatial variability in alpine snowfall and snow accumulation

Michael Lehning, Alexis Berne, Marc Schneebeli Zeugin, Danny Eddy Scipion Castillo

[1] In mountainous regions, snow accumulation on the ground is crucial for mountain hydrology and water resources. The present study investigates the link between the spatial variability in snowfall and in snow accumulation in the Swiss Alps. A mobile pola ...

Evaluating Ecohydrological Theories of Woody Root Distribution in the Kalahari

Paolo d'Odorico

The contribution of savannas to global carbon storage is poorly understood, in part due to lack of knowledge of the amount of belowground biomass. In these ecosystems, the coexistence of woody and herbaceous life forms is often explained on the basis of be ...

Spatial effects on species persistence and implications for biodiversity

Andrea Rinaldo, Enrico Bertuzzo, Lorenzo Mari, Samir Suweis, Amos Maritan

Natural ecosystems are characterized by striking diversity of form and functions and yet exhibit deep symmetries emerging across scales of space, time, and organizational complexity. Species-area relationships and species-abundance distributions are exampl ...

Metabolism of sulphonated anthraquinones in rhubarb, maize and celery: the role of cytochromes P450 and peroxidases

Jean-Paul Schwitzguebel

Sulphonated anthraquinones are precursors of many synthetic dyes and pigments, recalcitrant to biodegradation, and thus contaminating many industrial effluents and rivers. In the development of a phytotreatment to remove sulphonated aromatic compounds, rhu ...
