• Arctic greening from warming promotes declines in caribou populations 

      Fauchald, Per; Park, Taejin; Tømmervik, Hans; Myneni, Ranga B.; Hausner, Vera Helene (Journal article; Peer reviewed, 2017)
      Themigratory tundra caribou herds in North America follow decadal population cycles, and browsing from abundant caribou could be expected to counteract the current climate-driven expansion of shrubs in the circumpolar ...
    • Effects of human-induced disturbances and weather on herbivore movement 

      Leclerc, Martin; Tarroux, Arnaud; Fauchald, Per; Stien, Audun; Tveraa, Torkild; St-Laurent, Martin-Hugues (Journal article, 2019)
      Human-caused habitat disturbances and climate change are leading threats to biodiversity. Studying the impacts of human activities on wildlife from a behavioral perspective is a relevant starting point to understand the ...
    • Efficient sampling for ecosystem service supply assessment at a landscape scale 

      Murguzur, Francisco Javier Ancin; Munoz, Lorena; Monz, Christopher; Fauchald, Per; Hausner, Vera Helene (Journal article; Peer reviewed, 2019)
      Decision makers and stakeholders need high-quality data to manage ecosystem services (ES) efficiently. Landscape-level data on ES that are of sufficient quality to identify spatial tradeoffs, co-occurrence and hotspots ...
    • Foraging tactics in dynamic sea-ice habitats affect individual state in a long-ranging seabird 

      Tarroux, Arnaud; Cherel, Yves; Fauchald, Per; Kato, Akiko; Love, Oliver P.; Ropert-Coudert, Yan; Spreen, Gunnar; Varpe, Øystein; Weimerskirch, Henri; Yoccoz, Nigel; Zahn, Sandrine; Descamps, Sebastien (Peer reviewed; Journal article, 2020)
      1. Individual heterogeneity in diet and foraging behaviour is common in wild animal populations, and can be a strong determinant of how populations respond to environmental changes. Within populations, variation in ...
    • Light-level geolocators reveal spatial variations in interactions between northern fulmars and fisheries 

      Dupuis, Benjamin; Amélineau, Françoise; Tarroux, Arnaud; Bjørnstad, Oskar; Bråthen, Vegard Sandøy; Danielsen, Jóhannis; Descamps, Sebastien; Fauchald, Per; Hallgrimsson, Gunnar Thor; Hansen, Erpur Snær; Helberg, Morten; Helgason, Halfdan Helgi; Jónsson, Jón Einar; Kolbeinsson, Yann; Lorentzen, Erlend; Thompson, Paul; Thórarinsson, Thorkell Lindberg; Strøm, Hallvard (Peer reviewed; Journal article, 2021)
      Seabird−fishery interactions are a common phenomenon of conservation concern. Here, we highlight how light-level geolocators provide promising opportunities to study these interactions. By examining raw light data, it ...
    • Local land use associated with socio-economic development in six arctic regions 

      Ehrich, Dorothee; Thuestad, Alma Elizabeth; Tømmervik, Hans; Fauchald, Per; Hausner, Vera Helene (Journal article; Peer reviewed, 2018)
      The socioeconomic causes of land use change are complex. They are highly context dependent, but most often studied through case studies. Here, we use a quasi-experimental paired block design to investigate whether better ...
    • Phenology and cover of plant growth forms predict herbivore habitat selection in a high latitude ecosystem 

      Iversen, Marianne; Fauchald, Per; Langeland, Knut; Ims, Rolf Anker; Yoccoz, Nigel Gilles; Bråthen, Kari Anne (Journal article; Peer reviewed, 2014)
      The spatial and temporal distribution of forage quality is among the most central factors affecting herbivore habitat selection. Yet, for high latitude areas, forage quantity has been found to be more important than quality. ...
    • Spring phenology shapes the spatial foraging behavior of Antarctic petrels 

      Fauchald, Per; Tarroux, Arnaud; Tveraa, Torkild; Cherel, Yves; Ropert-Coudert, Yan; Kato, Akiko; Love, Oliver P.; Varpe, Øystein; Descamps, Sébastien (Journal article; Peer reviewed, 2017)
      In polar seas, the seasonal melting of ice triggers the development of an open-water ecosystem characterized by short-lived algal blooms, the grazing and development of zooplankton, and the influx of avian and mammalian ...
    • Temporal changes in the relative abundance of anadromous Arctic charr, brown trout, and Atlantic salmon in northern Europe: Do they reflect changing climates? 

      Svenning, Martin; Falkegård, Morten; Dempson, J. Brian; Power, Michael; Bårdsen, Bård-Jørgen; Guðbergsson, Gudni; Fauchald, Per (Peer reviewed; Journal article, 2021)
      1. Warming temperatures resulting from climate change may alter the distribution and abundance of many freshwater fish species, especially those in northern latitudes. Owing to interspecific differences in temperature ...
    • Transitions of social-ecological subsistence systems in the Arctic 

      Fauchald, Per; Hausner, Vera Helene; Schmidt, Jennifer Irene; Clark, Douglas A. (Journal article; Peer reviewed, 2017)
      Transitions of social-ecological systems (SES) expose governance systems to new challenges. This is particularly so in the Arctic where resource systems are increasingly subjected to global warming, industrial development ...
    • Tundra greenness 

      Epstein, Howard E.; Bhatt, U.S.; Raynolds, M.; Walker, D.; Pinzon, J.; Tucker, C.J.; Forbes, B.C.; Horstkotte, T.; Macias-Fauria, M.; Martin, A.; Phoenix, G.; Bjerke, Jarle W.; Tømmervik, Hans; Fauchald, Per; Vickers, H.; Myneni, R.; Park, T.; Dickerson, C.
