    • Actuarial senescence in a long-lived orchid challenges our current understanding of ageing 

      Dahlgren, Johan P.; Colchero, Fernando; Jones, Owen R.; Øien, Dag Inge; Moen, Asbjørn; Sletvold, Nina (Journal article; Peer reviewed, 2016)
      The dominant evolutionary theory of actuarial senescence—an increase in death rate with advancing age—is based on the concept of a germ cell line that is separated from the somatic cells early in life. However, such a ...

    • Actuarial senescence progresses similarly across sites and species in four boreal orchids 

      Tholstrup, Ditte Wiig; Sletvold, Nina; Øien, Dag-Inge; Moen, Asbjørn; Colchero, Fernando; Dahlgren, Johan Petter (Peer reviewed; Journal article, 2024)
      1. Whole-plant senescence, defined as a decrease in individual fitness as an organism grows older, has often been assumed to not occur in plants; however, it has now been detected in a range of plant taxa. Still, reported ...

    • Demographic responses to climate variation depend on spatial- and life history-differentiation at multiple scales 

      Tye, Matthew; Dahlgren, Johan P.; Øien, Dag-Inge; Moen, Asbjørn; Sletvold, Nina (Journal article; Peer reviewed, 2018)
      Long-term demographic data are needed for detailed viability analyses of populations threatened by climate change, but the infeasibility of obtaining such data makes it urgent to assess whether demographic responses to ...

    • Drivers of vegetative dormancy across herbaceous perennial plant species 

      Shefferson, Richard P.; Kull, Tiiu; Hutchings, Michael J.; Selosse, Marc-André; Jacquemyn, Hans; Kellett, Kimberly M.; Menges, Eric S.; Primack, Richard B.; Tuomi, Juha; Alahuhta, Kirsi; Hurskainen, Sonja; Alexander, Helen M.; Anderson, Derek S.; Brys, Rein; Brzosko, Emilia; Dostálik, Slavomir; Gregg, Katharine; Ipser, Zdenek; Jäkäläniemi, Anne; Jersáková, Jana; Kettle, W. Dean; McCormick, Melissa; Mendoza, Ana; Miller, Michael T.; Moen, Asbjørn; Øien, Dag-Inge; Püttsepp, Ülle; Roy, Mélanie; Sather, Nancy; Sletvold, Nina; Stípková, Zuzana; Tali, Kadri; Warren, Robert J. II; Whigham, Dennis F. (Journal article, 2018)
      Vegetative dormancy, that is the temporary absence of aboveground growth for ≥ 1 year, is paradoxical, because plants cannot photosynthesise or flower during dormant periods. We test ecological and evolutionary hypotheses ...
