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 ...

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

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

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 ...

Lowland plant arrival in alpine ecosystems facilitates a decrease in soil carbon content under experimental climate warming

Alexandre Buttler, Pierre Rémi Mariotte, Konstantin Svetlozarov Gavazov, Constant Signarbieux, Thomas Guillaume

Climate warming is releasing carbon from soils around the world, constituting a positive climate feedback. Warming is also causing species to expand their ranges into new ecosystems. Yet, in most ecosystems, whether range expanding species will amplify or ...

Species identity, rather than species mixtures, drives cover crop effects on nutrient partitioning in unfertilized agricultural soil

Alexandre Buttler, Pierre Rémi Mariotte, Lucas Georges Jean-Paul Freund, Mathieu Raymond Santonja

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 ...

Seasonal variability of groundwater level effects on the growth of Carex cinerascens in lake wetlands

Alexandre Buttler, Luca Bragazza, Pierre Rémi Mariotte, Wenjuan Feng, Mathieu Raymond Santonja

Groundwater level is crucial for wetland plant growth and reproduction, but the extent of its effect on plant growth can vary along with changed precipitation and temperature at different seasons. In this context, we investigated the effect of two groundwa ...

Linking soil's volatilome to microbes and plant roots highlights the importance of microbes as emitters of belowground volatile signals

Alexandre Buttler, Richard Splivallo, Pierre Rémi Mariotte, Amarante Vitra

Plants and microbes release a plethora of volatiles that act as signals in plant-microbe interactions. Characterizing soil's volatilome and microbiome might shed light on the nature of relevant volatile signals and on their emitters. This hypothesis was te ...

Responses of plant leaf economic and hydraulic traits mediate the effects of early- and late-season drought on grassland productivity

Alexandre Buttler, Pierre Rémi Mariotte, Constant Signarbieux, Claire Emilie Deléglise, Amarante Vitra, Lia Aimée Marie-Joe Lamacque

Drought can occur at different times during the grassland growing season, likely having contrasting effects on forage production when happening early or later in the season. However, knowledge about the interacting effects of the timing of drought and the ...

Nutrient limitations induced by drought affect forage N and P differently in two permanent grasslands

Alexandre Buttler, Pierre Rémi Mariotte, Claire Emilie Deléglise, Amarante Vitra

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 ...

Drought-induced decline of productivity in the dominant grassland species Lolium perenne L. depends on soil type and prevailing climatic conditions

Alexandre Buttler, Luca Bragazza, Pierre Rémi Mariotte, Konstantin Svetlozarov Gavazov, Géraldine Delphine Mercier, Constant Signarbieux, Amarante Vitra, Juan Carlos Quezada Rivera, Thomas Guillaume

Impact of drought on the functioning of grassland systems

Alexandre Buttler, Pierre Rémi Mariotte, Amarante Vitra

A rainfall manipulation experiment was conducted over a two-year period on two semi-natural grassland sites, in order to determine the effects of drought on both forage production (dry matter and nutritive value) and plant-soil relationships. Water stress ...

Separating sources of density-dependent and density-independent establishment limitation in invading species

Pierre Rémi Mariotte

Successful colonization by invasive species depends on both the ability to disperse seeds to a site and an ability to establish once seeds have arrived. While seed and establishment limitation are known to jointly influence colonization, decomposing establ ...

Positive litter feedbacks of an introduced species reduce native diversity and promote invasion in Californian grasslands

Pierre Rémi Mariotte

Questions: Californian grasslands have a long history of invasion, starting with the introduction of exotic forage species a century ago, and followed by newer waves of invaders. Both exotic and invasive species produce large amounts of litter, but the imp ...

Stoichiometric N:P flexibility and mycorrhizal symbiosis favour plant resistance against drought

Pierre Rémi Mariotte

Drought induces changes in the nitrogen (N) and phosphorus (P) cycle but most plant species have limited flexibility to take up nutrients under such variable or unbalanced N and P availability. Both the degree of flexibility in plant N:P ratio and of ro ...

Effect of crop rotation on mycorrhizal colonization and wheat yield under different fertilizer treatments

Pierre Rémi Mariotte

Break crops are used in agriculture to reduce soil pathogens and improve yield of subsequent cereal crops. However, they can also affect soil microbial communities beneficial to plant growth including arbuscular mycorrhizal fungi (AMF). Two wheat genotypes ...

Subordinate plant species moderate drought effects on earthworm communities in grasslands

Claire Guenat, Alexandre Buttler, Renée-Claire Le Bayon, Pierre Rémi Mariotte

Loss of plant diversity resulting from forecasted drought events is likely to alter soil functioning and affect earthworm communities. Plant-soil interactions are expected to play an important role in mediating climate change effects on soil decomposers. I ...
