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 ...

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 ...

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

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

The Legacy Effects of Winter Climate on Microbial Functioning After Snowmelt in a Subarctic Tundra

Konstantin Svetlozarov Gavazov

Warming-induced increases in microbial CO2 release in northern tundra may positively feedback to climate change. However, shifts in microbial extracellular enzyme activities (EEAs) may alter the impacts of warming over the longer term. We investigated the ...

Vascular plant-mediated controls on atmospheric carbon assimilation and peat carbon decomposition under climate change

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Luca Bragazza, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills, Remy Jean Henry Albrecht

Seasonality alters drivers of soil enzyme activity in subalpine grassland soil undergoing climate change

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Thomas Spiegelberger, Robert Thomas Edmund Mills

In mountain ecosystems with marked seasonality, climate change can affect various processes in soils, potentially modifying long-term key soil services via change in soil organic carbon (C) storage. Based on a four-year soil transplantation experiment in S ...

Long-term in situ permafrost thaw effects on bacterial communities and potential aerobic respiration

Konstantin Svetlozarov Gavazov, Vincent Eric Jules Jassey

2018

Climate change effects on the stability and chemistry of soil organic carbon pools in a subalpine grassland

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

Mountain soils stock large quantities of carbon as particulate organic matter that may be highly vulnerable to climate change. To explore potential shifts in soil organic matter (SOM) form and stability under climate change (warming and reduced precipitati ...

Springer2017

Winter ecology of a subalpine grassland: Effects of snow removal on soil respiration, microbial structure and function

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Robert Thomas Edmund Mills, Michael Bahn

Seasonal snow cover provides essential insulation for mountain ecosystems, but expected changes in precipitation patterns and snow cover duration due to global warming can influence the activity of soil microbial communities. In turn, these changes have th ...

Responses of soil properties and crop yields to different inorganic and organic amendments in a Swiss conventional farming system

Konstantin Svetlozarov Gavazov, Luca Bragazza, Guillaume Blanchet

In agro-ecosystems, fertilization practices are crucial for sustaining crop productivity. Here, based on a 50-year long-term experiment, we studied the influence of fertilization practices (inorganic and/or organic) and nitrogen (N) application rates on (i ...
