    • Abrupt high-latitude climate events and decoupled seasonal trends during the Eemian 

      Salonen, J. Sakari; Helmens, Karin F.; Brendryen, Jo; Kuosmanen, Niina; Väliranta, Minna; Goring, Simon; Korpela, Mikko; Kylander, Malin; Philip, Annemarie; Plikk, Anna; Renssen, Hans; Luoto, Miska (Peer reviewed; Journal article, 2018-07-20)
      The Eemian (the Last Interglacial; ca. 129–116 thousand years ago) presents a testbed for assessing environmental responses and climate feedbacks under warmer-than-present boundary conditions. However, climate syntheses ...

    • Compositional turnover and variation in Eemian pollen sequences in Europe 

      Felde, Vivian Astrup; Flantua, Suzette; Jenks, Cathy; Benito De Pando, Blas Manuel; de Beaulieu, Jacques Louis; Kuneš, Petr; Magri, Donatella; Nalepka, Dorota; Risebrobakken, Bjørg; ter Braak, Cajo J.F.; Allen, Judy R.

Sakari; Šeirienė, Vaida; Winter, Hanna; Tzedakis, P. Chronis; Birks, Harry John Betteley (Peer reviewed; Journal article, 2019)
      The Eemian interglacial represents a natural experiment on how past vegetation with negligible human impact responded to amplified temperature changes compared to the Holocene. Here, we assemble 47 carefully selected Eemian ...

    • 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 ...
