• Atmospheric circulation over Europe during the Younger Dryas 

      Rea, B.R.; Pellitero, R.; Spagnolo, M.; Hughes, P.D.; Ivy-Ochs, S.; Renssen, Hans; Ribolini, A.; Bakke, Jostein; Lukas, S.; Braithwaite, R.J. (Journal article; Peer reviewed, 2020)
      The Younger Dryas (YD) was a period of rapid climate cooling that occurred at the end of the last glaciation. Here, we present the first palaeoglacier-derived reconstruction of YD precipitation across Europe, determined ...
    • Chlamydial contribution to anaerobic metabolism during eukaryotic evolution 

      Stairs, Courtney W.; Sharamshi, Jennah E.; Tamarit, Daniel; Eme, Laura; Jørgensen, Steffen Leth; Spang, Anja; Ettema, Thijs J.G. (Journal article; Peer reviewed, 2020)
      The origin of eukaryotes is a major open question in evolutionary biology. Multiple hypotheses posit that eukaryotes likely evolved from a syntrophic relationship between an archaeon and an alphaproteobacterium based on ...
    • Earthquakes track subduction fluids from slab source to mantle wedge sink 

      Halpaap, Felix; Rondenay, Stéphane; Perrin, Alexander; Goes, Saskia; Ottemöller, Lars; Austrheim, Håkon; Shaw, Robert; Eeken, Thomas (Peer reviewed; Journal article, 2019)
      Subducting plates release fluids as they plunge into Earth’s mantle and occasionally rupture to produce intraslab earthquakes. It is debated whether fluids and earthquakes are directly related. By combining seismic ...
    • How is a turbidite actually deposited? 

      Ge, Zhiyuan; Nemec, Wojciech; Vellinga, Age; Gawthorpe, Robert Leslie (Journal article; Peer reviewed, 2022)
      The deposition of a classic turbidite by a surge-type turbidity current, as envisaged by conceptual models, is widely considered a discrete event of continuous sediment accumulation at a falling rate by the gradually waning ...
    • Lake sediments with Azorean tephra reveal ice-free conditions on coastal northwest Spitsbergen during the Last Glacial Maximum 

      Bilt, Willem van der; Lane, Christine S. (Peer reviewed; Journal article, 2019-10-23)
      Lake sediments retrieved from the beds of former nonerosive ice sheets offer unique possibilities to constrain changes in the extent and style of past glaciation, and place them in an absolutely dated context. We present ...
    • North Atlantic surface ocean warming and salinization in response to middle Eocene greenhouse warming 

      van der Ploeg, Robin; Cramwinckel, Margot J.; Kocken, Ilja J.; Leutert, Thomas Jan; Bohaty, Steven M.; Fokkema, Chris D.; Hull, Pincelli M.; Meckler, Anna Nele; Middelburg, Jack J.; Müller, Inigo A.; Penman, Donald E.; Peterse, Francien; Reichart, Gert-Jan; Sexton, Philip F.; Vahlenkamp, Maximilian; De Vleeschouwer, David; Wilson, Paul A.; Ziegler, Martin; Sluijs, Appy (Journal article; Peer reviewed, 2023)
      Quantitative reconstructions of hydrological change during ancient greenhouse warming events provide valuable insight into warmer-than-modern hydrological cycles but are limited by paleoclimate proxy uncertainties. We ...
    • Postglacial species arrival and diversity buildup of northern ecosystems took millennia 

      Alsos, Inger Greve; Rijal, Dilli Prasad; Ehrich, Dorothee; Karger, Dirk Nikolaus; Yoccoz, Nigel; Heintzman, Peter D.; Brown, Antony; Lammers, Youri; Pellissier, Loïc; Alm, Torbjørn; Bråthen, Kari Anne; Coissac, Eric; Merkel, Marie Føreid; Alberti, Adriana; Denoeud, France; Bakke, Jostein (Journal article; Peer reviewed, 2022)
      What drives ecosystem buildup, diversity, and stability? We assess species arrival and ecosystem changes across 16 millennia by combining regional-scale plant sedimentary ancient DNA from Fennoscandia with near-complete ...
    • Sedimentary ancient DNA shows terrestrial plant richness continuously increased over the Holocene in northern Fennoscandia 

      Rijal, Dilli Prasad; Heintzman, Peter D.; Lammers, Youri; Yoccoz, Nigel; Lorberau, Kelsey; Pitelkova, Iva; Goslar, Tomasz; Murguzur, Francisco Javier Ancin; Salonen, J. Sakari; Helmens, Karin F.; Bakke, Jostein; Edwards, Mary E.; Alm, Torbjørn; Bråthen, Kari Anne; Brown, Antony; Alsos, Inger Greve (Journal article; Peer reviewed, 2021)
      The effects of climate change on species richness are debated but can be informed by the past. Here, we generated a sedimentary ancient DNA dataset covering 10 lakes and applied novel methods for data harmonization. We ...
