Hydrological dynamics and fire history of the last 1300 years in western Siberia reconstructed from a high-resolution, ombrotrophic peat archive

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

Siberian peatlands provide records of past changes in the continental climate of Eurasia. We analyzed a core from Mukhrino mire in western Siberia to reconstruct environmental change in this region over the last 1300 years. The pollen analysis revealed lit ...

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 ...

Characterization 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 ...

Microclimatological consequences for plant and microbial composition in Sphagnum-dominated peatlands

Luca Bragazza, Bjorn Jozef Maria Robroek

In three Scandinavian peatlands we studied to what extent plant and microbial community compositions are governed by local-scale microhabitat, with a special interest in the effect of aspect (i.e. exposition of slopes). Despite differences in solar irradia ...

Indirect 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 ...

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 ...

Plant functional types define magnitude of drought response in peatland CO2 exchange

Luca Bragazza, Bjorn Jozef Maria Robroek

Peatlands are important sinks for atmospheric carbon (C), yet the role of plant functional types (PFTs) for C sequestration under climatic perturbations is still unclear. A plant-removal experiment was used to study the importance of vascular PFTs for the ...

Impacts by dams: From water quality modelling to management optimization

Alfred Johny Wüest

Dams are prone to causing negative effects on downstream ecosystems by their potential to alter riverine water quality. In the case of Itezhi-Tezhi Reservoir (Zambia), a nutrient-poor wetland located downstream is affected by low oxygen concentrations owin ...
