      Bjorkman, Anne D.; Myers-Smith, Isla H.; Elmendorf, Sarah C.; Normand, Signe; Rüger, Nadja; Beck, Pieter S. A.; Blach-Overgaard, Anne; Blok, Daan; Cornelissen, J. Hans C.; Forbes, Bruce C.; Georges, Damien; Goetz, Scott J.; Guay, Kevin C.; Henry, Gregory H.R.; HilleRisLambers, Janneke; Hollister, Robert D.; Karger, Dirk N.; Kattge, Jens; Manning, Peter; Prevéy, Janet S.; Rixen, Christian; Schaepman-Strub, Gabriela; Thomas, Haydn J.D.; Vellend, Mark; Wilmking, Martin; Wipf, Sonja; Carbognani, Michele; Hermanutz, Luise; Lévesque, Esther; Molau, Ulf; Petraglia, Alessandro; Soudzilovskaia, Nadejda A.; Spasojevic, Marko J.; Tomaselli, Marcello; Vowles, Tage; Alatalo, Juha M.; Alexander, Heather D.; Anadon-Rosell, Alba; Angers-Blondin, Sandra; te Beest, Mariska; Berner, Logan; Björk, Robert G.; Buchwal, Agata; Buras, Allan; Christie, Katherine; Cooper, Elisabeth J.; Dullinger, Stefan; Elberling, Bo; Eskelinen, Anu; Frei, Esther R.; Grau, Oriol; Grogan, Paul; Hallinger, Martin; Semenschuk, Philipp; Speed, James David Mervyn; Hofgaard, Annika (Journal article; Peer reviewed, 2018)
      The tundra is warming more rapidly than any other biome on Earth, and the potential ramifications are far-reaching because of global feedback effects between vegetation and climate. A better understanding of how environmental ...

    • Post-1980 shifts in the sensitivity of boreal tree growth to North Atlantic Ocean dynamics and seasonal climate 

      Ols, Clementine; Trouet, Valerie; Girardin, Martin P.; Hofgaard, Annika; Bergeron, Yves; Drobyshev, Igor (Journal article; Peer reviewed, 2018)
      The mid-20th century changes in North Atlantic Ocean dynamics, e.g. slow-down of the Atlantic meridional overturning thermohaline circulation (AMOC), have been considered as early signs of tipping points in the Earth climate ...

    • Reproduction as a bottleneck to treeline advance across the circumarctic forest tundra ecotone 

      Brown, Carissa D.; Dufour-Tremblay, Geneviève; Jameson, Ryan G.; Mamet, Steven D.; Trant, Andrew J.; Walker, Xanthe J.; Boudreau, Stephane; Harper, Karen A.; Henry, Grepory H.R.; Hermanutz, Luise; Hofgaard, Annika; Isaeva, Ludmila; Kershaw, G. Peter; Johnstone, Jill F. (Journal article; Peer reviewed, 2018)
      The fundamental niche of many species is shifting with climate change, especially in sub-arctic ecosystems with pronounced recent warming. Ongoing warming in sub-arctic regions should lessen environmental constraints on ...

    • Sensitivity to environmental change of the treeline ecotone and its associated biodiversity in European mountains 

      Wielgolaski, Frans Emil; Hofgaard, Annika; Holtmeier, Friedrich-Karl (Journal article; Peer reviewed, 2017)
      Transition zones between mountain forests and treeless tundra, i.e. treeline ecotones, are characterized by great regional variety. In this paper, we discuss the biodiversity in various trophic levels in treeline ecotones ...

    • Spatiotemporal variation in the relationship between boreal forest productivity proxies and climate data 

      Ols, Clémentine; Kålås, Ingvil Henden; Drobyshev, Igor; Söderström, Lars; Hofgaard, Annika (Peer reviewed; Journal article, 2019)
      The impacts of climate change on high-latitude forest ecosystems are still uncertain. Divergent forest productivity trends have recently been reported both at the local and regional level challenging the projections of ...

    • Stand structure, recruitment and growth dynamics in mixed subalpine spruce and Swiss stone pine forests in the Eastern Carpathians 

      Popa, Ionel; Nechita, Constantin; Hofgaard, Annika (Journal article; Peer reviewed, 2017)
      Natural subalpine forests are considered to be sensitive to climate change, and forest characteristics are assumed to reflect the prevalent disturbance regime. We hypothesize that stand history determines different stand ...

    • Tilpasninger til klimaendringer i Nord-Norge og på Svalbard. Vurdering av vernebehovet og terrestriske økosystemers evne til å binde karbon
