Linking Leaf Economic Traits With Forage Quality Across Temperate Grasslands Under Ambient and Drought Conditions

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra

Increases in droughts may disrupt the life‐supporting services of grasslands, including the forage provision for herbivores. However, less is known about drought impacts on forage quality (i.e., dynamics of the cell characteristics of leaves and stems of h ...

Legacy Effects of Flooding Duration on Growth and Reproductive Traits of Carex cinerascens in the Poyang Lake Wetland

Alexandre Buttler, Pierre Rémi Mariotte, Mathieu Raymond Santonja

Alteration of flooding regimes due to global change may have cascading effects on plant community composition and associated ecosystem services. Here, we experimentally investigated the effects of six flooding regimes with contrasting combinations of flood ...

Spatio-temporal patterns and drivers of CH4 and CO2 fluxes from rivers and lakes in highly urbanized areas

Alexandre Buttler

Gaseous carbon exchange at the water-air interface of rivers and lakes is an essential process for regional and global carbon cycle assessments. Many studies have shown that rivers surrounding urban landscapes can be hotspots for greenhouse gas (GHG) emiss ...

Combining X-ray micro-CT and microscopy-based images of two lianas species to derive structural, mechanical and functional relationships

Alexandre Buttler, Anastasios Vassilopoulos, Pascal Turberg, Claudine Bettina Karlen

This paper presents a biomechanical study of stems of two liana species, Clematis vitalba and Vitis vinifera, investigates the mechanical performance of these two liana species and attempts to enhance the understanding of structure-function relationships. ...

Impacts of snow-farming on alpine soil and vegetation: A case study from the Swiss Alps

Alexandre Buttler, Pierre Rémi Mariotte, Rodolphe Schlaepfer, Juan Carlos Quezada Rivera, Lucas Georges Jean-Paul Freund

Snow-farming is one of the adaptive strategies used to face the snow deficit in ski resorts. We studied the impact of a shifting snow-farming technique on a pasture slope in Adelboden, Switzerland. Specifically, we compared plots covered by a compressed sn ...

Nutrient availability challenges the sustainability of low-input oil palm farming systems

Alexandre Buttler

The social and economic benefits for smallholders cultivating oil palms are usually associated with environmental degradation and high resource consumption inherent to intensive farming systems. Nonetheless, the extensification of agricultural practices by ...

Food web structure and energy flux dynamics, but not taxonomic richness, influence microbial ecosystem functions in a Sphagnum-dominated peatland

Alexandre Buttler, Edward Mitchell, Vincent Eric Jules Jassey

Soil microbial communities are vital for multiple ecosystem processes and services. In particular, soil microbial food webs are key determinants of soil biodiversity, functioning and stability. Unclear, however, is how struc-tural features of food webs, su ...

Ericoid shrub encroachment shifts aboveground-belowground linkages in three peatlands across Europe and Western Siberia

Alexandre Buttler, Rodolphe Schlaepfer

In northern peatlands, reduction of Sphagnum dominance in favour of vascular vegetation is likely to influence biogeochemical processes. Such vegetation changes occur as the water table lowers and temperatures rise. To test which of these factors has a sig ...

Deforestation-free land-use change and organic matter-centered management improve the C footprint of oil palm expansion

Alexandre Buttler

In recent decades, mounting evidence has indicated that the expansion of oil palm (OP) plantations at the expense of tropical forest has had a far pernicious effect on ecosystem aspects. While various deforestation-free strategies have been proposed to enh ...

Above- and below-ground responses to experimental climate forcing in two forb species from montane wooded pastures in Switzerland

Alexandre Buttler, Konstantin Svetlozarov Gavazov

Mountain ecosystems are particularly threatened by ongoing climate change and the species composition of high elevation grasslands is already changing. An open research question is how these ecosystems will adapt to changes in their key environmental const ...
