Modern pollen-vegetation relationships in the Champsaur valley (French Alps) and their potential in the interpretation of fossil pollen records of past cultural landscapes

Alexandre Buttler

This study is an attempt to evaluate the relationships between the vegetation and the modem pollen rain as a contribution to palaeoecological research. Pollen analysis of surface moss polsters and floristic records has been undertaken for 51 sampling point ...

Nitrogen-enriched compost application combined with plant growth-promoting rhizobacteria (PGPR) improves seed quality and nutrient use efficiency of sunflower

Alexandre Buttler, Luca Bragazza

Ecological benefits associated with plant growth-promoting rhizobacteria (PGPR) inoculants offer a promising integrated nutrient management option to counteract plant nitrogen (N) deficiency. We performed field experiments to evaluate the effect of integra ...

Subordinate plant species moderate drought effects on earthworm communities in grasslands

Alexandre Buttler, Claire Guenat, 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 ...

Asymmetric effects of cooler and warmer winters on beech phenology last beyond spring

Alexandre Buttler, Rodolphe Schlaepfer, Constant Signarbieux, María Paula Sanginés De Cárcer

In temperate trees, the timings of plant growth onset and cessation affect biogeochemical cycles, water, and energy balance. Currently, phenological studies largely focus on specific phenophases and on their responses to warming. How differently spring phe ...

Modern pollen assemblages from grazed vegetation in the western Pyrenees, France: a numerical tool for more precise reconstruction of past cultural landscapes

Alexandre Buttler

Modern pollen assemblages from grazed vegetation in the Pyrenees Mountains (France) were studied with the aim of providing a calibrated model for reconstructing past pastoral activities. The modern analogues were selected to cover the major gradients of gr ...

Seasonal influence of climate manipulation on microbial community structure and function in mountain soils

Alexandre Buttler, Bjorn Jozef Maria Robroek, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Thomas Spiegelberger

Microbial communities drive soil organic matter (SOM) decomposition through the production of a variety of extracellular enzymes. Climate change impact on soil microbial communities and soil enzymatic activities can therefore strongly affect SOM turnover, ...

Shifts in wind energy potential following land-use driven vegetation dynamics in complex terrain

Alexandre Buttler, Fernando Porté Agel, François Golay, Jiannong Fang, Alexander Ludwig Johannes Peringer

Many mountainous regions with high wind energy potential are characterized by multi-scale variabilities of vegetation in both spatial and time dimensions, which strongly affect the spatial distribution of wind resource and its time evolution. To this end, ...

Soil microbial community changes in wooded mountain pastures due to simulated effects of cattle grazing

Alexandre Buttler, François Gillet

The effect of cattle activity on pastures can be subdivided into three categories of disturbances: herbage removal, dunging and trampling. The objective of this study was to assess separately or in combination the effect of these factors on the potential a ...

Modeling Social-Ecological Feedback Effects in the Implementation of Payments for Environmental Services in Pasture-Woodlands

Alexandre Buttler, François Gillet, Alexander Ludwig Johannes Peringer

An effective implementation of payment for environmental services (PES) must allow for complex interactions of coupled social-ecological systems. We present an integrative study of the pasture-woodland landscape of the Swiss Jura Mountains combining method ...

Carbon balance of a European mountain bog at contrasting stages of regeneration

Alexandre Buttler, Andy Siegenthaler

Carbon dioxide and methane (CH4) fluxes were measured in a cutover bog of the Jura Mountains (France) together with biotic and abiotic variables for two entire vegetation periods in order to compare the carbon balance of the bog at three stages of regenera ...

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

Alexandre Buttler, Pierre Rémi Mariotte, Constant Signarbieux, Konstantin Svetlozarov Gavazov, 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 ...

Carbon neutral expansion of oil palm plantations in the Neotropics

Alexandre Buttler, Thomas Guillaume, Juan Carlos Quezada Rivera

Alternatives to ecologically devastating deforestation land use change trajectories are needed to reduce the carbon footprint of oil palm (OP) plantations in the tropics. Although various land use change options have been proposed, so far, there are no emp ...

Climatic modifiers of the response to nitrogen deposition in peat-forming Sphagnum mosses: a meta-analysis

Alexandre Buttler, Luca Bragazza

Peatlands in the northern hemisphere have accumulated more atmospheric carbon (C) during the Holocene than any other terrestrial ecosystem, making peatlands long-term C sinks of global importance. Projected increases in nitrogen (N) deposition and temperat ...

Above- and belowground linkages in Sphagnum peatland: climate warming affects plant-microbial interactions

Alexandre Buttler, Vincent Eric Jules Jassey

Peatlands contain approximately one third of all soil organic carbon (SOC). Warming can alter above- and belowground linkages that regulate soil organic carbon dynamics and C-balance in peatlands. Here we examine the multiyear impact of in situ experimenta ...

Heuristic-driven Graph Wavelet Modeling of Complex Terrain

Alexandre Buttler, François Golay, Alexander Ludwig Johannes Peringer

We present a novel method for building a multiresolution representation of large digital surface models. The surface points coincide with the nodes of a planar graph which can be processed using a critically sampled, invertible lifting scheme. To drive the ...

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. ...

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

Alexandre Buttler, Pierre Rémi Mariotte, 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 ...

Slash-and-burn agriculture and tropical cyclone activity in Madagascar: Implication for soil fertility dynamics and corn performance

Alexandre Buttler, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Thomas Guillaume, Justine Marie Gay des Combes

On the western coast of Madagascar, the dry tropical forest of Kirindy may disappear in the next 50 years because of its rapid conversion into agricultural land by slash-and-burn cultivation. The slash-and-burn fields are cultivated during 3 years in avera ...

The influence of competition from herbaceous vegetation and shade on simulated browsing tolerance of coniferous and deciduous saplings

Alexandre Buttler, Charlotte Vandenberghe

The ability of saplings to tolerate browsing (i.e. the ability to persist with reduced biomass and to compensate for biomass loss) is influenced by the level of stress and their growth strategies. Ultimately, insight into species-specific responses of sapl ...
