    A continuous biomass‐burning record based on the fire biomarker levoglucosan of sediment core GeoB9528-3 (2019)
    PANGAEA
    In:  Supplement to: Schreuder, Laura T; Hopmans, Ellen C; Castañeda, Isla S; Schefuß, Enno; Mulitza, Stefan; Sinninghe Damsté, Jaap S; Schouten, Stefan (2019): Late Quaternary biomass burning in Northwest Africa and interactions with climate, vegetation, and humans.

    Description: Biomass burning on the African continent is widespread and interactions with climate, vegetation dynamics and biogeochemical cycling are complex. To obtain a better understanding of these complex relationships, African fire history has been widely studied, although mostly on relatively short time-scales (i.e. yrs to kyrs) and less commonly on long-term scales. Here, we present a 192-kyr, continuous biomass-burning record from sub-Saharan Northwest Africa based on the fire biomarker levoglucosan in a marine sediment core offshore Guinea. Notable features of our record include an increase in levoglucosan accumulation at 80 ka and two peaks at 50-60 ka. The event at 80 ka is likely related to an overall increase in sedimentation rates rather than an increase in biomass burning in the Northwest African savanna region. Our record indicates that glacial/interglacial changes in regional climate and vegetation composition (C3 vs. C4 plants) were not a major influence on biomass burning over the last 192 kyrs. However, we suggest that the burning events at 50-60 ka might be caused by increased occurrence of C3 vegetation and human settlement in this region. At this time, the savanna region became wetter and fuel loads likely increased. Therefore, the region was more hospitable for humans, who likely used fire for hunting activities. Collectively, we hypothesize that on longer (glacial/interglacial) timescales, biomass burning, regional climate and African vegetation are not necessarily coupled, while around 50-60 ka, higher fuel loads and human fire-use may have influenced fire occurrence in sub-Saharan Northwest Africa.

    d15N of lipids in marine animals of the Dutch Wadden Sea (2015)
    PANGAEA
    In:  Supplement to: Svensson, Elisabeth; Schouten, Stefan; Hopmans, Ellen C; Middelburg, Jack J; Sinninghe Damsté, Jaap S (2016): Factors Controlling the Stable Nitrogen Isotopic Composition (d15N) of Lipids in Marine Animals. PLoS ONE, 11(1), e0146321, https://doi.org/10.1371/journal.pone.0146321

    Description: Lipid extraction of biomass prior to stable isotope analysis is known to cause variable changes in the stable nitrogen isotopic composition (d15N) of residual biomass. However, the underlying factors causing these changes are not yet clear. Here we address this issue by comparing the d15N of bulk and residual biomass of several marine animal tissues (fish, crab, cockle, oyster, and polychaete), as well as the d15N of the extracted lipids. As observed previously, lipid extraction led to a variable offset in d15N of biomass (differences ranging from -2.3 to +1.8 per mil). Importantly, the total lipid extract (TLE) was highly depleted in 15N compared to bulk biomass, and also highly variable (differences ranging from -14 to +0.7 per mil). The TLE consisted mainly of phosphatidylcholines, a group of lipids with one nitrogen atom in the headgroup. To elucidate the cause for the 15N-depletion in the TLE, the d15N of amino acids was determined, including serine because it is one of the main sources of nitrogen to N-containing lipids. Serine d15N values differed by -7 to +2 per mil from bulk biomass d15N, and correlated well with the 15N depletion in TLEs. On average, serine was less depleted (-3 per mil) than the TLE (-7 per mil), possibly due to fractionation during biosynthesis of N-containing headgroups, or that other nitrogen-containing compounds, such as urea and choline, or recycled nitrogen contribute to the nitrogen isotopic composition of the TLE. The depletion in 15N of the TLE relative to biomass increased with the trophic level of the organisms.
