    • Clitellate worms (Annelida) in late-glacial and Holocene sedimentary DNA records from the Polar Urals and northern Norway 

      Lammers, Youri; Clarke, Charlotte; Erséus, Christer; Brown, Antony Gavin; Edwards, Mary Elizabeth; Gielly, Ludovic; Haflidason, Haflidi; Mangerud, Jan; Rota, E; Svendsen, John-Inge; Alsos, Inger Greve (Peer reviewed; Journal article, 2018-11-26)
      While there are extensive macro‐ and microfossil records of a range of plants and animals from the Quaternary, earthworms and their close relatives amongst annelids are not preserved as fossils and therefore the knowledge ...

    • How well can near infrared reflectance spectroscopy (NIRS) measure sediment organic matter in multiple lakes? 

      Ancin Murguzur, Francisco Javier; Brown, Antony; Clarke, Charlotte; Sjøgren, Per Johan E; Svendsen, John-Inge; Alsos, Inger Greve (Journal article; Peer reviewed, 2020)
      Loss-on-ignition (LOI) is the most widely used measure of organic matter in lake sediments, a variable related to both climate and land-use change. The main drawback for conventional measurement methods is the processing ...

    • Late Quaternary dynamics of Arctic biota from ancient environmental genomics 

      Wang, Yucheng; Pedersen, Mikkel W.; Alsos, Inger Greve; De Sanctis, Bianca; Racimo, Fernando; Prohaska, Ana; Coissac, Eric; Owens, Hannah L.; Merkel, Marie Føreid; Fernandez-Guerra, Antonio; Rouillard, Alexandra; Lammers, Youri; Alberti, Adriana; Denoeud, France; Money, Daniel; Ruter, Anthony H.; McColl, Hugh; Larsen, Nicolaj K.; Cherezova, Anna A.; Edwards, Mary E.; Fedorov, Grigory B.; Haile, James; Orlando, Ludovic; Vinner, Lasse; Korneliussen, Thorfinn S.; Beilman, David W.; Bjørk, Anders A.; Cao, Jialu; Dockter, Christoph; Esdale, Julie; Gusarova, Galina; Kjeldsen, Kristian K.; Mangerud, Jan; Rasic, Jeffrey T.; Skadhauge, Birgitte; Svendsen, John Inge; Tikhonov, Alexei N.; Wincker, Patrick; Xing, Yingchun; Zhang, Yubin; Froese, Duane G.; Rahbek, Carsten; Nogues, David B; Holden, Philip B.; Edwards, Neil R.; Durbin, Richard; Meltzer, David J.; Kjær, Kurt H.; Moller, Per; Willerslev, Eske (Journal article; Peer reviewed, 2021)
      During the last glacial–interglacial cycle, Arctic biotas experienced substantial climatic changes, yet the nature, extent and rate of their responses are not fully understood1,2,3,4,5,6,7,8. Here we report a large-scale ...

    • Persistence of arctic-alpine flora during 24,000 years of environmental change in the Polar Urals 

      Clarke, Charlotte, L.; Edwards, Mary, E.; Gielly, L; Ehrich, Dorothee; Hughes, P.D.M.; Morozova, L.M.; Haflidason, Haflidi; Mangerud, Jan; Svendsen, John-Inge; Alsos, Inger Greve (Peer reviewed; Journal article, 2019-12-23)
      Plants adapted to extreme conditions can be at high risk from climate change; arctic-alpine plants, in particular, could “run out of space” as they are out-competed by expansion of woody vegetation. Mountain regions could ...

    • 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 reveals local vegetation changes driven by glacial activity and climate 

      Elliott, Lucas Dane; Rijal, Dilli Prasad; Brown, Antony; Bakke, Jostein; Topstad, Lasse; Heintzman, Peter D.; Alsos, Inger Greve (Journal article; Peer reviewed, 2023)
      Disentangling the effects of glaciers and climate on vegetation is complicated by the confounding role that climate plays in both systems. We reconstructed changes in vegetation occurring over the Holocene at Jøkelvatnet, ...

    • 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 ...
