Environmental and taxonomic controls of carbon and oxygen stable isotope composition in Sphagnum across broad climatic and geographic ranges

Luca Bragazza, Mariusz Lamentowicz, Bjorn Jozef Maria Robroek

Rain-fed peatlands are dominated by peat mosses (Sphagnum sp.), which for their growth depend on nutrients, water and CO2 uptake from the atmosphere. As the isotopic composition of carbon (C-12(,)13) and oxygen (O-16(,)18) of these Sphagnum mosses are affe ...

Combining short-term manipulative experiments with long-term palaeoecological investigations at high resolution to assess the response of Sphagnum peatlands to drought, fire and warming

Alexandre Buttler, Vincent Eric Jules Jassey, Mariusz Lamentowicz

Northern hemisphere peatlands are substantial carbon stores. However, recent climate change and human impacts (e.g., drainage and atmospheric nutrient deposition) may trigger the emission of their stored carbon to the atmosphere. Biodiversity losses are al ...

Peatland vascular plant functional types affect dissolved organic matter chemistry

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Adrian Pulgarin, Remy Jean Henry Albrecht, Samuel Thomas Gabriel Hamard

Northern peatlands are large repositories of carbon. Peatland vascular plant community composition has been functionally associated to a set of biogeochemical processes such as carbon cycling. Yet, we do not fully understand to what extent vascular plant f ...

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 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 ...

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 ...

Do peatlands hibernate?

Alexandre Buttler, Vincent Eric Jules Jassey, Constant Signarbieux, Robert Thomas Edmund Mills

Winter seasonality with low amounts of incoming radiation, frost and snow cover characterize large areas at mid- and high latitudes, especially in the arctic and in mountain ranges. Because of these adverse conditions, it is often assumed that ecosystem pr ...

Plant functional diversity drives niche-size-structure of dominant microbial consumers along a poor to extremely rich fen gradient

Vincent Eric Jules Jassey, Mariusz Lamentowicz, Bjorn Jozef Maria Robroek

Plant community composition is recognized more and more for playing an important role in ecosystem processes, such as C cycling. In particular, plant functional type (PFT) composition seems to have a key regulatory role, yet the underlying mechanisms in ...

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 ...
