Contribution to characterisation of biochar to estimate the labile fraction of carbon
Abstract Different analytical techniques were used to find the most reliable and economic method for determining the labile fraction of C in biochar. Biochar was produced from pine, poplar and willowExpand
Can pyrolysis-GC/MS be used to estimate the degree of thermal alteration of black carbon?
Abstract Very little is known about the macromolecular properties of biomass combustion residues referred to as black carbon (BC). Pyrolysis-gas chromatography–mass spectrometry (Py-GC/MS) wasExpand
Long-term deforestation in NW Spain: linking the Holocene fire history to vegetation change and human activities
Abstract The Holocene fire regime is thought to have had a key role in deforestation and shrubland expansion in Galicia (NW Spain) but the contribution of past societies to vegetation burning remainsExpand
Epidemiology of flea infestation of ruminants in Libya.
A significantly higher proportion of intensive farms had animals with flea infestation compared to semi-intensive farms, and four stockmen were found infested with a total of 176 C. felis strongylus, which suggests that this subspecies is also a potential zoonosis. Expand
Thermally assisted hydrolysis and methylation of purified tannins from plants.
A collection of tannins extracted from various plant species was subjected to thermally assisted hydrolysis and methylation (THM) using tetramethylammonium hydroxide. The products obtained includedExpand
Evaluating pyrolysis–GC/MS and 13C CPMAS NMR in conjunction with a molecular mixing model of the Penido Vello peat deposit, NW Spain
Abstract We performed solid state 13 C cross-polarization magic angle spinning (CPMAS) nuclear magnetic resonance (NMR) spectroscopy and pyrolysis–gas chromatography/mass spectrometry (Py–GC/MS) onExpand
Characterisation of aged charcoal using a coil probe pyrolysis-GC/MS method optimised for black carbon
Abstract Molecular identification of aged black carbon (BC) is problematic owing to potential interference of non-charred aromatic organic matter and to a general lack of techniques that are capableExpand
Fate of biochar in chemically- and physically-defined soil organic carbon pools
Abstract The objective was to elucidate the fate of biochar in physically- and chemically-defined fractions of organic carbon (OC) in soil after 510 days of laboratory incubation. Fresh corn stoverExpand
Post-disturbance vegetation dynamics during the Late Pleistocene and the Holocene: An example from NW Iberia
This is the post-print version of the final paper published in Global and Planetary Change. The published article is available from the link below. Changes resulting from the publishing process, suchExpand
Holocene vegetation changes in NW Iberia revealed by anthracological and palynological records from a colluvial soil
Macroscopic charcoal, pollen and non-pollen palynomorphs were isolated from a colluvial soil located on a small hill in Campo Lameiro (NW Spain) in order to elucidate the vegetation history of theExpand
