A novel testate amoebae trait-based approach to infer environmental disturbance in Sphagnum peatlands
Vincent Eric Jules Jassey, Mariusz Lamentowicz
Species' functional traits are closely related to ecosystem processes through evolutionary adaptation, and are thus directly connected to environmental changes. Species' traits are not commonly used in palaeoecology, even though they offer powerful advanta ...
Nature Publishing Group2016Experimental warming differentially affects microbial structure and activity in two contrasted moisture sites in a Sphagnum-dominated peatland
Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey
Several studies on the impact of climate warming have indicated that peat decomposition/mineralization will be enhanced. Most of these studies deal with the impact of experimental warming during summer when prevalent abiotic conditions are favorable to dec ...
Elsevier2015An unexpected role for mixotrophs in the response of peatland carbon cycling to climate warming
Alexandre Buttler, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Constant Signarbieux, Bjorn Jozef Maria Robroek, Enrique Lara, Robert Thomas Edmund Mills, Bertrand Fournier
Mixotrophic protists are increasingly recognized for their significant contribution to carbon (C) cycling. As phototrophs they contribute to photosynthetic C fixation, whilst as predators of decomposers, they indirectly influence organic matter decompositi ...
Nature Publishing Group2015Indirect effects of experimental warming on dissolved organic carbon content in subsurface peat
Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey
The peatland carbon store is threatened by climate change and is expected to provide positive feedback on air temperature. Most studies indicate that enhanced temperature and microbial activities result in a rise of dissolved organic carbon (DOC) as a cons ...
Springer Heidelberg2014Characterization of structural disturbances in peats by X-ray CT-based density determinations
Alexandre Buttler, Pascal Turberg, Fränz Zeimetz
Bulk densitywas determined indirectly in peat samples by X-ray computed tomography (X-ray CT) and compared with density values obtained by standard laboratory methods. Five Histosols were collected in the same cut-over peatland, representing various degree ...
Wiley-Blackwell2014Snow 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 ...
Springer Netherlands2013Biogeochemical plant-soil microbe feedback in response to climate warming in peatlands
Alexandre Buttler, Luca Bragazza, Richard David Bardgett, Julien Parisod
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 ...
Nature Publishing Group2013Summer methane fluxes from a boreal bog in northern Quebec, Canada, using eddy covariance measurements
A boreal bog located in the James Bay lowlands, Canada, was instrumented with an open-path gas analyzer to monitor the turbulent fluxes of methane throughout the summer of 2012. The mostly continuous eddy covariance measurements permitted the study of meth ...
Pergamon-Elsevier Science Ltd2013High nitrogen deposition alters the decomposition of bog plant litter and reduces carbon accumulation
Alexandre Buttler, Luca Bragazza, Jonathan Habermacher
Bogs are globally important sinks of atmospheric carbon (C) due to the accumulation of partially decomposed litter that forms peat. Because bogs receive their nutrients from the atmosphere, the world-wide increase of nitrogen (N) deposition is expected to ...
2012Glasshouse 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 ...
