    • 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 ...

      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 ...
