Diminished soil functions occur under simulated climate change in a sup-alpine pasture, but heterotrophic temperature sensitivity indicates microbial resilience

Alexandre Buttler, Thomas Spiegelberger, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills

The pressure of climate change is disproportionately high in mountainous regions, and small changes may push ecosystem processes beyond sensitivity thresholds, creating new dynamics of carbon and nutrient cycling. Given that the rate of organic matter deco ...

Biotic and Abiotic Constraints on the Decomposition of Fagus sylvatica Leaf Litter Along an Altitudinal Gradient in Contrasting Land-Use Types

Alexandre Buttler, Thomas Spiegelberger, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills

Climate change can affect the process of carbon cycling and leaf litter decomposition in multiple ways, both directly and indirectly, though the strength and direction of this relationship is often context dependent. In this experiment, we followed decompo ...

Seasonal patterns of testate amoeba diversity, community structure and species-environment relationships in four Sphagnum-dominated peatlands along a 1300 m altitudinal gradient in Switzerland

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Mariusz Lamentowicz, Vincent Eric Jules Jassey

Altitudinal gradients are useful to study the potential effects of climate change on ecosystems. Historically, studies on elevation gradients have primarily focused on macro-organisms and ecosystem processes, while microorganisms have been mostly ignored d ...

Sustainable Land-use Practices in European Mountain Regions under Global Change: an Integrated Research Approach

Alexandre Buttler

This Special Feature on sustainable land-use practices in European mountain regions presents results from the inter- and transdisciplinary research project MOUNTLAND. The goal was to investigate the sensitivity of the provision of ecosystem services to bot ...

How do subordinate and dominant species in semi-natural mountain grasslands relate to productivity and land-use change?

Alexandre Buttler, Pierre Rémi Mariotte, Thomas Spiegelberger

Changes in agricultural practices of semi-natural mountain grasslands are expected to modify plant community structure and shift dominance patterns. Using vegetation surveys of 11 sites in semi-natural grasslands of the Swiss Jura and Swiss and French Alps ...

Biogeochemical plant-soil microbe feedback in response to climate warming in peatlands

Alexandre Buttler, Luca Bragazza, Julien Parisod, Richard David Bardgett

Peatlands act as global sinks of atmospheric carbon (C) through the accumulation of organic matter(1), primarily made up of decay-resistant litter of peat mosses(2). However, climate warming has been shown to promote vascular plant growth in peatlands, esp ...

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

Alexandre Buttler, Edward Mitchell, 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 ...

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 ...

Dynamics of Forage Production in Pasture-woodlands of the Swiss Jura Mountains under Projected Climate Change Scenarios

Alexandre Buttler, François Gillet, Thomas Spiegelberger, Konstantin Svetlozarov Gavazov, Alexander Ludwig Johannes Peringer

Silvopastoral systems of the Swiss Jura Mountains serve as a traditional source of forage and timber in the subalpine vegetation belt, but their vulnerability to land use and climate change puts their future sustainability at stake. We coupled experimental ...

Factors modulating cottongrass seedling growth stimulation to enhanced nitrogen and carbon dioxide: compensatory tradeoffs in leaf dynamics and allocation to meet potassium-limited growth

Alexandre Buttler, Andy Siegenthaler, Edward Mitchell, Jean-Michel Gobat

Eriophorum vaginatum is a characteristic species of northern peatlands and a keystone plant for cutover bog restoration. Understanding the factors affecting E. vaginatum seedling establishment (i.e. growth dynamics and allocation) under global change has p ...

Snow cover manipulation effects on microbial community structure and soil chemistry in a mountain bog

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek

Alterations in snow cover driven by climate change may impact ecosystem functioning, including biogeochemistry and soil (microbial) processes. We elucidated the effects of snow cover manipulation (SCM) on above-and belowground processes in a temperate peat ...

A Contextual Analysis of Land-Use and Vegetation Changes in Two Wooded Pastures in the Swiss Jura Mountains

Joël Chételat, Michaël Kalbermatten, Alexandre Buttler, François Gillet, Thomas Spiegelberger, Kathryn Lannas, Alexander Ludwig Johannes Peringer

This study examines the effects of land-use policies and natural events on the evolution of two wooded pastures in the Jura Mountains in Switzerland between 1934 and 2000. The socioeconomic context and the local conditions were seen as major driving forces ...

The Response of the Mediterranean Gorgonian Eunicella singularis to Thermal Stress Is Independent of Its Nutritional Regime

Alexandre Buttler, Leïla Ezzat

Over the last few decades, sessile benthic organisms from the Mediterranean Sea have suffered from the global warming of the world's oceans, and several mass mortality events were observed during warm summers. It has been hypothesized that mortality could ...

Sustainable Land Use in Mountain Regions Under Global Change: Synthesis Across Scales and Disciplines

Alexandre Buttler, François Gillet, Thomas Spiegelberger, Heike Lischke, Adrienne Grêt-Regamey

Mountain regions provide essential ecosystem goods and services (EGS) for both mountain dwellers and people living outside these areas. Global change endangers the capacity of mountain ecosystems to provide key services. The Mountland project focused on th ...

Subordinate plant species impact on soil microbial communities and ecosystem functioning in grasslands: Findings from a removal experiment

Alexandre Buttler, Charlotte Vandenberghe, Pierre Rossi, Claire Meugnier, Pierre Rémi Mariotte, Richard David Bardgett

Despite their low relative abundance, subordinate plant species may have larger impacts on ecosystem functioning than expected, but their role in plant communities remains poorly understood. The aim of this study was to test how subordinate plant species i ...

Past and future landscape dynamics in pasture-woodlands of the Swiss Jura Mountains under climate change

Joël Chételat, Alexandre Buttler, François Gillet, Thomas Spiegelberger, Alexander Ludwig Johannes Peringer

Silvopastoral systems are traditional components of the landscape in the Swiss Jura Mountains, and are promising approaches for the sustainable management of mountain areas worldwide. Due to complex vegetation dynamics, pasture-woodlands are very vulnerabl ...

Subordinate plant species enhance community resistance against drought in semi-natural grasslands

Alexandre Buttler, Charlotte Vandenberghe, Pierre Rémi Mariotte

According to the insurance hypothesis, more diverse plant communities are more likely to be resistant to drought. Whilst many experiments have been carried out to determine the effects of plant diversity on plant community insurance, the results are still ...

The relationship between plant species richness and soil aggregate stability can depend on disturbance

Alexandre Buttler

Plant diversity has been shown to significantly increase topsoil aggregate stability of machine-graded ski slopes. We hypothesise that this effect is specific for these disturbed sites and that at sites of low and no disturbance the effect decreases. ...

Glasshouse vs field experiments: do they yield ecologically similar results for assessing N impacts on peat mosses?

Alexandre Buttler, Edward Mitchell, Luca Bragazza

Peat bogs have accumulated more atmospheric carbon (C) than any other terrestrial ecosystem today. Most of this C is associated with peat moss (Sphagnum) litter. Atmospheric nitrogen (N) deposition can decrease Sphagnum production, compromising the C seque ...
