    • High genomic diversity in the endangered East Greenland Svalbard Barents Sea stock of bowhead whales (Balaena mysticetus) 

      Cerca, José; Westbury, Michael V; Heide-Jørgensen, Mads-Peter; Kovacs, Kit M.; Lorenzen, Eline D.; Lydersen, Christian; Shpak, Olga V.; Wiig, Øystein; Bachmann, Lutz (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-12)
      The East Greenland-Svalbard-Barents Sea (EGSB) bowhead whale stock (Balaena mysticetus) was hunted to near extinction and remains Endangered on the International Union of Conservation of Nature Red List. The intense, temporally extensive hunting pressure may have left the population vulnerable to other perturbations, such as environmental change. However, the lack of genomic baseline data renders ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-11)
      Aim: Identify hotspots and areas of high species richness for Arctic marine mammals.<p><p> Location: Circumpolar Arctic. <p>Methods: A total of 2115 biologging devices were deployed on marine mammals from 13 species in the Arctic from 2005 to 2019. Getis-Ord Gi* hotspots were calculated based on the number of individuals in grid cells for each species and for phyloge-netic groups (nine pinnipeds, ...

    • Marine mammal hotspots in the Greenland and Barents Seas 

      Hamilton, Charmain Danielle; Lydersen, Christian; Aars, Jon; Biuw, Martin; Boltunov, Andrei; Born, Erik W.; Dietz, Rune; Folkow, Lars; Glazov, Dmitry M.; Haug, Tore; Heide-Jørgensen, Mads-Peter; Kettemer, Lisa Elena; Laidre, Kristin L.; Øien, Nils Inge; Nordøy, Erling Sverre; Rikardsen, Audun H.; Rosing-Asvid, Aqqalu; Semenova, Varvara; Shpak, Olga V.; Sveegaard, Signe; Ugarte, Fernando; Wiig, Øystein; Kovacs, Kit M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-04)
      Environmental change and increasing levels of human activity are threats to marine mam- mals in the Arctic. Identifying marine mammal hot - spots and areas of high species richness are essential to help guide management and conservation efforts. Herein, space use based on biotelemetric tracking devices deployed on 13 species (ringed seal <i>Pusa hispida</i>, bearded seal <i>Erignathus ...

    • Mitogenomics and the genetic differentiation of contemporary Balaena mysticetus (Cetacea) from Svalbard 

      Bachmann, Lutz; Cabrera, Andrea A.; Heide-Jørgensen, Mads-Peter; Shpak, Olga V.; Lydersen, Christian; Wiig, Øystein; Kovacs, Kit M. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-08-12)
      Full mitochondrial genomes were assembled for 12 recently sampled animals from the Svalbard bowhead whale (Balaena mysticetus) stock via high-throughput sequencing data, facilitating analysis of the demographic history of the population for the first time. The Svalbard population has retained noticeable amounts of mitochondrial genome diversity despite extreme historical harvest levels. Haplotype ...

    • Modeling the demography of species providing extended parental care: A capture–recapture multievent model with a case study on polar bears (Ursus maritimus) 

      Cubaynes, Sarah; Aars, Jon; Yoccoz, Nigel; Pradel, Roger; Wiig, Øystein; Ims, Rolf Anker; Gimenez, Olivier (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-10)
      <ol> <li>In species providing extended parental care, one or both parents care for altricial young over a period including more than one breeding season. We expect large parental investment and long-term dependency within family units to cause high variability in life trajectories among individuals with complex consequences at the population level. So far, models for estimating demographic ...

    • Prevalence of antibodies against Brucella spp. in West Greenland polar bears (Ursus maritimus) and East Greenland muskoxen (Ovibos moschatus) 

      Sonne, Christian; Andersen-Ranberg, Emilie; Rajala, Elisabeth; Agerholm, Jørgen S.; Bonefeld-Jørgensen, Eva; Desforges, Jean-Pierre; Eulaers, Igor; Gustavson, Kim; Jenssen, Bjørn Munro; Koch, Anders; Rosing-Asvid, Aqqalu; Schmidt, Nils Martin; Grøndahl, Carsten; Mosbacher, Jesper Bruun; Siebert, Ursula; Tryland, Morten; Mulvad, Gert; Born, Erik W; Laidre, Kristin; Wiig, Øystein; Dietz, Rune; Magnusson, Ulf (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-19)
      Zoonotic infections transmitted from terrestrial and marine mammals to humans in European Arctic are of unknown significance, despite considerable potential for transmission due to local hunt and a rapidly changing environment. As an example, infection with <i>Brucella</i> bacteria may have significant impact on human health due to consumption of raw meat or otherwise contact with tissues and fluids ...

    • Sea ice reduction drives genetic differentiation among Barents Sea polar bears 

      Maduna, Simo; Aars, Jon; Fløystad, Ida; Klutsch, Cornelya; Fiskebeck, Eve Marie Louise Zeyl; Wiig, Øystein; Ehrich, Dorothee; Andersen, Magnus; Bachmann, Lutz; Derocher, Andrew E.; Nyman, Tommi; Eiken, Hans Geir; Hagen, Snorre (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-08)
      Loss of Arctic sea ice owing to climate change is predicted to reduce both genetic diversity and gene flow in ice-dependent species, with potentially negative consequences for their long-term viability. Here, we tested for the population-genetic impacts of reduced sea ice cover on the polar bear (<i>Ursus maritimus</i>) sampled across two decades (1995–2016) from the Svalbard Archipelago, Norway, ...

(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-02-02)
      Global warming is affecting the population dynamics and trophic interactions across a wide range of ecosystems and habitats. Translating these real-time effects into their long-term consequences remains a challenge. The rapid and extreme warming period that occurred after the Last Glacial Maximum (LGM) during the Pleistocene–Holocene transition (7–12 thousand years ago) provides an opportunity ...
