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 ... -
Stable Southern Hemisphere westerly winds throughout the Holocene until intensification in the last two millennia
van der Bilt, Willem Godert Maria; D’Andrea, William J.; Oppedal, Lea Toska; Bakke, Jostein; Bjune, Anne Elisabeth; Zwier, Maaike (Journal article; Peer reviewed, 2022)The Southern Hemisphere westerly winds sustain the Southern Ocean’s role as one of Earth’s main carbon sinks, and have helped sequester nearly half the anthropogenic CO2 stored in the ocean. Observations show shifts in the ... -
Using microcomputed tomography (μCT) to count varves in lake sediment sequences: Application to Lake Sagtjernet, Eastern Norway
Ballo, Eirik Gottschalk; Bajard, Manon Juliette Andree; Støren, Eivind; Bakke, Jostein (Journal article; Peer reviewed, 2023)Varved lake sediments are one of the most important natural archives that allow annual resolution paleoclimate reconstructions. Conventional varve counting techniques use thin sections to manually identify lamina. However, ...
