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 ...

Peatland vascular plant functional types affect dissolved organic matter chemistry

Alexandre Buttler, Luca Bragazza, Vincent Eric Jules Jassey, Bjorn Jozef Maria Robroek, Remy Jean Henry Albrecht, Adrian Pulgarin, 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 ...

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

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

Whisking-Related Changes in Neuronal Firing and Membrane Potential Dynamics in the Somatosensory Thalamus of Awake Mice

Carl Petersen

The thalamus transmits sensory information to the neocortex and receives neocortical, subcortical, and neuromodulatory inputs. Despite its obvious importance, surprisingly little is known about thalamic function in awake animals. Here, using intracellular ...

Nitrogen limitation and microbial diversity at the treeline

Alexandre Buttler, Julien Roy, Aurélie Thébault

Tree growth limitation at treeline has mainly been studied in terms of carbon limitation while effects and mechanisms of potential nitrogen (N) limitation are barely known, especially in the southern hemisphere. We investigated how soil abiotic properties ...

Holocene changes in climate and land use drove shifts in the diversity of testate amoebae in a subalpine pond

Mariusz Lamentowicz

Testate amoebae that inhabit peat are sensitive indicators of water table position. In this study, we used testate amoebae in sediments from a mire in the western Alps (Lac du Thyl) to: (1) reconstruct the hydrology of the site over the last 7,000 years, ( ...

Modern pollen rain and fungal spore assemblages from pasture woodlands around Lake Saint-Point (France)

François Gillet

Modern analogs are commonly used to investigate the relationships between modern pollen rain and the surrounding present vegetation and to improve our interpretation of fossil data. We collected modern pollen and spore rain in 18 more or less grazed and/or ...

Community development along a proglacial chronosequence: are above-ground and below-ground community structure controlled more by biotic than abiotic factors?

François Gillet, Edward Mitchell

P>1. We studied vascular plant and soil-dwelling testate amoeba communities in deglaciated sites across a range of substrate ages in Kenai Fjords, Alaska, USA to test four hypotheses. (i) Patterns of community assembly are similar for vascular plants and t ...

Alginate-based microcapsules for mammalian cell culture and other biotechnological applications

Véronique Breguet

Since life began, nature has been using the envelopment of systems for their protection or for providing a particular reaction space, the enveloping wall displaying additional specific membrane functions. The abundance of examples is quite overwhelming and ...
