    • Cold acclimation in warmer extended autumns impairs freezing tolerance of perennial ryegrass (Lolium perenne) and timothy (Phleum pratense) 

      Dalmannsdottir, Sigridur; Jørgensen, Marit; Rapacz, Marcin; Østrem, Liv; Larsen, Arild; Rødven, Rolf; Rognli, Odd Arne (Journal article; Peer reviewed, 2017-02-01)
      The effect of variable autumn temperatures in combination with decreasing irradiance and daylength on photosynthesis, growth cessation and freezing tolerance was investigated in northern- and southern-adapted populations ...

    • Influence of Arctic light conditions on crop production and quality 

      Mølmann, Jørgen A; Dalmannsdottir, Sigridur; Hykkerud, Anne Linn; Hytönen, Timo; Samkumar, Amos; Jaakola, Laura (Peer reviewed; Journal article, 2021-04-10)
      The natural light conditions above the Arctic Circle are unique in terms of annual variation creating special growth conditions for crop production. These include low solar elevations, very long daily photosynthetic light ...

    • Major shifts in species' relative abundance in grassland mixtures alongside positive effects of species diversity in yield: a continental-scale experiment 

      Brophy, Caroline; Finn, John A.; Lüscher, Andreas; Suter, Matthias; Kirwan, Laura; Sebastià, Maria-Teresa; Helgadóttir, Áslaug; Baadshaug, Ole Hans; Bélanger, Gilles; Black, Alistair; Collins, Rosemary P.; Čop, Jure; Dalmannsdottir, Sigridur; Delgado, Ignacio; Elgersma, Anjo; Fothergill, Michael; Frankow-Lindberg, Bodil E.; Ghesquiere, An; Golinska, Barbara; Golinski, Piotr; Grieu, Philippe; Gustavsson, Anne-Maj; Höglind, Mats; Huguenin-Elie, Olivier; Jørgensen, Marit; Kadziuliene, Zydre; Kurki, Päivi; Llurba, Rosa; Lunnan, Tor; Porqueddu, Claudio; Thumm, Ulrich; Connolly, John (Journal article, 2017)
      1. Increased species diversity promotes ecosystem function; however, the dynamics of multi-speciesgrassland systems over time and their role in sustaining higher yields generated by increased diver-sity are still poorly ...

    • Recent warming across the North Atlantic region may be contributing to an expansion in barley cultivation 

      Martin, Peter; Dalmannsdottir, Sigridur; Gerdinum, Jens Ivan í; Halland, Hilde; Hermannsson, Jonatan; Kavanagh, Vanessa; MacKenzie, Katrin; Reykdal, Olafur; Russell, Joanne; Sveinsson, Saemundur; Thomsen, Mette; Wishart, John (Journal article; Peer reviewed, 2017-12)
      Although grass dominates most agricultural systems in the North Atlantic region (NAR), spring barley is the most important cereal and is used for animal feed and food and drink products. Recent changes in climate have ...

    • Weed suppression greatly increased by plant diversity in intensively managed grasslands: A continental-scale experiment 

      Connolly, John; Sebastià, Maria-Teresa; Kirwan, Laura; Finn, John Anthony; Llurba, Rosa; Suter, Matthias; Collins, Rosemary P.; Porqueddu, Claudio; Helgadóttir, Áslaug; Baadshaug, Ole Hans; Bélanger, Gilles; Black, Alistair; Brophy, Caroline; Čop, Jure; Dalmannsdottir, Sigridur; Ignacio, Delgado; Elgersma, Anjo; Fothergill, Michael; Frankow-Lindberg, Bodil E.; An, Ghesquiere; Piotr, Golinski; Grieu, Philippe; Anne-Maj, Gustavsson; Höglind, Mats; Olivier, Huguenin-Elie; Jørgensen, Marit; Kadziuliene, Zydre; Lunnan, Tor; Nykanen-Kurki, Paivi; Ribas, Angela; Taube, Friedhelm; Thumm, Ulrich; De Vliegher, Alex; Lüscher, Andreas (Journal article; Peer reviewed, 2018-03)
      1. Grassland diversity can support sustainable intensification of grassland production through increased yields, reduced inputs and limited weed invasion. We report the effects of diversity on weed suppression from 3 years ...

    • Yield predictions of timothy (Phleum pratense L.) in Norway under future climate scenarios 

      Hellton, Kristoffer Herland; Amdahl, Helga; Thorarinsdottir, Thordis; Alsheikh, Muath K; Aamlid, Trygve S.; Jørgensen, Marit; Dalmannsdottir, Sigridur; Rognli, Odd Arne (Peer reviewed; Journal article, 2023-07-26)
      The perennial forage grass timothy (Phleum pratense L.) is the most important forage crop in Norway. Future changes in the climate will affect growing conditions and hence the yield output. We used data from the Norwegian ...
