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

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 ...

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, 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 ...

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

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

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, Pierre Rémi Mariotte, Amarante Vitra, Richard Splivallo

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, Amarante Vitra, Claire Emilie Deléglise, 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, 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 ...
