Journal ArticleDOI
FTIR spectroscopy can be used as a screening tool for organic matter quality in regenerating cutover peatlands
Rebekka R. E. Artz,Stephen J. Chapman,A.H. Jean Robertson,Jacqueline M. Potts,Fatima Laggoun-Défarge,Sébastien Gogo,Laure Comont,Jean-Robert Disnar,André-Jean Francez +8 more
TL;DR: In this paper, Fourier transform infrared (FTIR) spectra were used to predict the organic matter composition in peat samples at various stages of peatland regeneration from five European countries.
Journal ArticleDOI
Above‐ and belowground linkages in Sphagnum peatland: climate warming affects plant‐microbial interactions
Vincent E. J. Jassey,Vincent E. J. Jassey,Vincent E. J. Jassey,Geneviève Chiapusio,Philippe Binet,Alexandre Buttler,Alexandre Buttler,Alexandre Buttler,Fatima Laggoun-Défarge,Fatima Laggoun-Défarge,Frédéric Delarue,Frédéric Delarue,Nadine Bernard,Edward A. D. Mitchell,Marie-Laure Toussaint,André-Jean Francez,Daniel Gilbert +16 more
TL;DR: It is suggested that warming will destabilize C and nutrient recycling of peatlands via changes in above- and belowground linkages, and therefore, the microbial food web associated with mosses will feedback positively to global warming by destabilizing the carbon cycle.
Journal ArticleDOI
Introducing global peat-specific temperature and pH calibrations based on brGDGT bacterial lipids
Bernhard David A Naafs,Gordon N. Inglis,Yanhong Zheng,Matthew J. Amesbury,Harald Biester,Richard Bindler,Jerome Blewett,M. A. Burrows,Dennis Del Castillo Torres,Frank M. Chambers,A. D. Cohen,Richard P. Evershed,Sarah J. Feakins,Mariusz Gałka,Angela V. Gallego-Sala,Laure Gandois,D. M. Gray,Patrick G. Hatcher,E.N. Honorio Coronado,Paul D.M. Hughes,Arnaud Huguet,Mari Könönen,Fatima Laggoun-Défarge,Outi Lähteenoja,Mariusz Lamentowicz,Rob Marchant,Erin L McClymont,Xabier Pontevedra-Pombal,Camilo Ponton,Ali Pourmand,A. M. Rizzuti,Line Rochefort,Judith Schellekens,F. De Vleeschouwer,Richard D. Pancost +34 more
TL;DR: In this article, the authors investigate the distribution of brGDGTs in 470 samples from 96 peatlands around the world with a broad mean annual air temperature (−8 to 27 °C) and pH (3-8) range and present the first peat-specific brGGT-based temperature and pH calibrations.
Journal ArticleDOI
Exploitation of northern peatlands and biodiversity maintenance: a conflict between economy and ecology
Steve Chapman,Alexandre Buttler,André-Jean Francez,Fatima Laggoun-Défarge,Harri Vasander,Michael Schloter,Jean Combe,P. Grosvernier,Hauke Harms,Daniel Epron,Daniel Gilbert,Edward A. D. Mitchell +11 more
TL;DR: In this paper, a close analysis suggests that limited peat extraction may actually increase biodiversity in some cases, and may be sustainable over the long term, and what conditions govern the re-establishment of a diverse community and the ability to sequester carbon.
Journal ArticleDOI
FTIR Study of Pure Vitrains and Associated Coals
TL;DR: In this paper, a semiquantitative analysis of the infrared spectra from 650 to 4000 cm −1 of six vitrains and the coals associated with three of them is presented.
