Persistent high temperature and low precipitation reduce peat carbon accumulation

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Constant Signarbieux, Bjorn Jozef Maria Robroek, Remy Jean Henry Albrecht

Extreme climate events are predicted to become more frequent and intense. Their ecological impacts, particularly on carbon cycling, can differ in relation to ecosystem sensitivity. Peatlands, being characterized by peat accumulation under waterlogged condi ...

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 ...

Experimental 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 ...

An 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 ...

Experimental warming interacts with soil moisture to discriminate plant responses in an ombrotrophic peatland

Alexandre Buttler, Pierre Rémi Mariotte, Edward Mitchell, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Cédric Pochelon

QuestionA better understanding of the response of Sphagnum mosses and associated vascular plants to climate warming is relevant for predicting the carbon balance of peatlands in a warmer world. Open-top chambers (OTCs) have been used to investigate the eff ...

Peatland vascular plant functional types affect methane dynamics by altering microbial community structure

Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Robert Thomas Edmund Mills

Peatlands are natural sources of atmospheric methane (CH4), an important greenhouse gas. It is established that peatland methane dynamics are controlled by both biotic and abiotic conditions, yet the interactive effect of these drivers is less studied and ...

Linking soil microbial communities to vascular plant abundance along a climate gradient

Alexandre Buttler, Edward Mitchell, Luca Bragazza, Richard David Bardgett

The ongoing expansion of shrub cover in response to climate change represents a unique opportunity to explore the link between soil microbial communities and vegetation changes. This link is particularly important in peatlands where shrub expansion is expe ...

Reconstructing climate change and ombrotrophic bog development during the last 4000 years in northern Poland using biotic proxies, stable isotopes and trait-based approach

Vincent Eric Jules Jassey, Mariusz Lamentowicz

In this study, we present a record spanning the last 4000 years from a Baltic bog (Kusowskie Bagno) in northern Poland. Using numerous biotic and abiotic proxies, such as testate amoebae (depth to water table reconstructions), stable carbon isotopes (C-13) ...

Climate change, vegetation dynamics and carbon cycling in peatlands: the role of vascular plants in CO2 sequestration

Konstantin Svetlozarov Gavazov, Robert Matthew Mills, Luca Bragazza, Bjorn Jozef Maria Robroek

The project VeganPeat is described in this poster. IN particular, the workpackage oncerning the quantification of 14C in soil respired CO2 to detect the role of vascular plant abundance in promoting the decomposition of old organic matter in two peatlands ...
