    • Circum-Arctic distribution of chemical anti-herbivore compounds suggests biome-wide trade-off in defence strategies in Arctic shrubs 

      Lindén, Elin; te Beest, Mariska; Aubreu, Ilka; Moritz, Thomas; Sundqvist, Maja K.; Barrio, Isabel C.; Boike, Julia; Bryant, John P.; Bråthen, Kari Anne; Buchwal, Agata; Bueno, C. Guillermo; Currier, Alain; Egelkraut, Dagmar Dorothea; Forbes, Bruce C.; Hallinger, Martin; Heijmans, Monique; Hermanutz, Luise; Hik, David S.; Hofgaard, Annika; Holmgren, Milena; Huebner, Diane C.; Høye, Toke T.; Jónsdóttir, Ingibjörg S.; Kaarlejärvi, Elina; Kissler, Emilie; Kumpula, Timo; Limpens, Juul; Myers-Smith, Isla H.; Normand, Signe; Post, Eric; Rocha, Adrian V.; Schmidt, Niels Martin; Skarin, Anna; Soininen, Eeva M; Sokolov, Aleksandr; Sokolova, Natalia; Speed, James David Mervyn; Street, Lorna E.; Tananaev, Nikita; Tremblay, Jean-Pierre; Urbanowicz, Christine; Watts, David A.; Zimmermann, Heike H.; Olofsson, Johan (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-08-30)
      Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top–down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, non-resinous shrubs could be more influenced by herbivores than more defended, resinous shrubs. However, sparse field measurements limit our current understanding of how much of the ...

    • Estimating the cumulative impact and zone of influence of anthropogenic features on biodiversity 

      Niebuhr, Bernardo Brandão; Van Moorter, Bram; Stien, Audun; Tveraa, Torkild; Strand, Olav; Langeland, Knut; Sandstrom, Per; Alam, Moudud; Skarin, Anna; Panzacchi, Manuela (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-02)
      1. The concept of cumulative impacts is widespread in policy documents, regu-lations and ecological studies, but quantification methods are still evolving. Infrastructure development usually takes place in landscapes with preexist-ing anthropogenic features. Typically, their impact is determined by computing the distance to the nearest feature only, thus ignoring the potential cumulative impacts of ...

    • Reindeer behavioural ecology and use of pastures in pastoral livelihoods 

      Skarin, Anna; Kumpula, Jouko; Tveraa, Torkild; Åhman, Birgitta (Chapter; Bokkapittel, 2022)
      Reindeer pastoralists have, for centuries, followed free-roaming animals throughout the Eurasian Arctic. The closing of national borders about a century ago forced the reindeer pastoralists to adapt to new conditions. Today, environmental conditions are changing rapidly with climate and land use change. Local history, migration and pasture use strategies of reindeer herding, and also the biogeography ...

    • Trophic interactions and abiotic factors drive functional and phylogenetic structure of vertebrate herbivore communities across the Arctic tundra biome 

      Speed, James David Mervyn; Skjelbred, Ina Åsnes; Barrio, Isabel C.; Martin, Michael David; Berteaux, Dominique; Bueno, Guillermo; Christie, Katie; Forbes, Bruce C.; Forbey, Jennifer; Fortin, Daniel; Grytnes, John-Arvid; Hoset, Katrine Skamfer; Lecomte, Nicolas; Marteinsdottir, Bryndis; Mosbacher, Jesper Bruun; Pedersen, Åshild Ø.; Ravolainen, Virve; Rees, Eileen C.; Skarin, Anna; Sokolova, Natalya; Thornhill, Andrew H; Tombre, Ingunn; Soininen, Eeva M (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-29)
      Communities are assembled from species that evolve or colonise a given geographic region, and persist in the face of abiotic conditions and interactions with other species. The evolutionary and colonisation histories of communities are characterised by phylogenetic diversity, while functional diversity is indicative of abiotic and biotic conditions. The relationship between functional and phylogenetic ...
