Environmental drivers of carbon and nitrogen isotopic signatures in peatland vascular plants along an altitude gradient

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Luca Bragazza

Peatlands are important sinks of atmospheric carbon (C) that, in response to climate warming, are undergoing dynamic vegetation succession. Here we examined the hypothesis that the uptake of nutrients by different plant growth forms (PGFs) is one key mecha ...

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

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

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, ...

Transplantation of subalpine wood-pasture turfs along a natural climatic gradient reveals lower resistance of unwooded pastures to climate change compared to wooded ones

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Thomas Spiegelberger

Climate change could impact strongly on cold-adapted mountain ecosystems, but little is known about its interaction with traditional land-use practices. We used an altitudinal gradient to simulate a year-round warmer and drier climate for semi-natural suba ...

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

Alexandre Buttler, Konstantin Svetlozarov Gavazov, Thomas Spiegelberger, 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, Konstantin Svetlozarov Gavazov, Thomas Spiegelberger, 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 ...

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

Alexandre Buttler, Konstantin Svetlozarov Gavazov, François Gillet, Thomas Spiegelberger, 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 ...

Subalpine Pasture-Woodlands in a Changing Climate : the Role of Land Use Type in Ecosystem Resistance to Simulated Climate Change

Konstantin Svetlozarov Gavazov

Climate change in temperate mountain systems and associated increase in temperature and decrease in precipitation are expected to have strong implications for vegetation productivity, species diversity and carbon turnover in subalpine grasslands. Little is ...

Preservation of Wooded pastures in the Jura: climatic and agricultural Policy challenges

Alexandre Buttler, Pierre Rémi Mariotte, Konstantin Svetlozarov Gavazov, François Gillet, Thomas Spiegelberger, Joël Chételat, Alexander Ludwig Johannes Peringer

Isotopic analysis of cyanobacterial nitrogen fixation associated with subarctic lichen and bryophyte species

Konstantin Svetlozarov Gavazov

Dinitrogen fixation by cyanobacteria is of particular importance for the nutrient economy of cold biomes, constituting the main pathway for new N supplies to tundra ecosystems. It is prevalent in cyanobacterial colonies on bryophytes and in obligate associ ...
