      Since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to organohalogen compounds (OHCs) in Arctic biota, there has been a considerable number of new Arctic effect studies. Here, we provide an update on the state of the knowledge of OHC, and also include mercury, exposure and/or associated effects in key Arctic marine and terrestrial ...

    • Haematology and clinical blood chemistry in harbour porpoises (Phocoena phocoena) from the inner Danish waters 

      Siebert, Ursula; Blanchet, Marie-Anne; Teilmann, Jonas; Anderson Hansen, Kirstin; Kristensen, Jakob; Bunskoek, Paulien; Dietz, Rune; Desforges, Jean-Pierre; Sonne, Christian; Desportes, Geneviève (Journal article; Tidsskriftartikkel, 2020-07-13)
      Harbour porpoises (<i>Phocoena phocoena</i>) in the Baltic Sea are under increasing pressure from anthropogenic activities, which affect the overall health of populations. Individuals’ haematologic and biochemistry parameters are known to be linked to a population’s health status and are therefore useful tools for cross-population comparisons and to assess health patterns of a population through ...

    • Mandibular shape in farmed Arctic foxes (Vulpes lagopus) exposed to persistent organic pollutants 

      Bradley, Madison M.; Perra, Megan; Ahlstrøm, Øystein; Jenssen, Bjørn Munro; Jørgensen, Even Hjalmar; Fuglei, Eva; Muir, Derek C.G.; Sonne, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-26)
      We investigated if dietary exposure to persistent organic pollutants (POPs) affect mandibular asymmetry and periodontal disease in paired male-siblings of Arctic foxes (<i>Vulpes lagopus</i>). During ontogeny, one group of siblings was exposed to the complexed POP mixture in naturally contaminated minke whale (<i>Balaenoptere acutorostarta</i>) blubber (n = 10), while another group was given wet ...

    • 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 ...

    • Quantitative fatty acid signature analysis reveals a high level of dietary specialization in killer whales across the North Atlantic 

      Remili, Anaïs; Dietz, Rune; Sonne, Christian; Samarra, Filipa I. P.; Rikardsen, Audun H.; Kettemer, Lisa Elena; Ferguson, Steven H.; Watt, Cortney A.; Matthews, Cory J. D.; Kiszka, Jeremy J.; Jourdain, Eve Marie; Borgå, Katrine; Ruus, Anders; Granquist, Sandra M.; Rosing-Asvid, Aqqalu; McKinney, Melissa A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-13)
      Quantifying the diet composition of apex marine predators such as killer whales (Orcinus orca) is critical to assessing their food web impacts. Yet, with few exceptions, the feeding ecology of these apex predators remains poorly understood. <p>Here, we use our newly validated quantitative fatty acid signature analysis (QFASA) approach on nearly 200 killer whales and over 900 potential prey to model ...

    • A risk assessment of the effects of mercury on Baltic Sea, Greater North Sea and North Atlantic wildlife, fish and bivalves 

      Dietz, Rune; Fort, Jérôme; Sonne, Christian; Albert, Céline; Bustnes, Jan Ove; Christensen, Thomas Kjær; Ciesielski, Tomasz Maciej; Danielsen, Jóhannis; Dastnai, Sam; Eens, Marcel; Erikstad, Kjell E; Galatius, Anders; Garbus, Svend-Erik; Gilg, Oliver; Hanssen, Sveinn Are; Helander, Björn; Helberg, Morten; Jaspers, Veerle; Jenssen, Bjørn Munro; Jónsson, Jón Einar; Kauhala, Kaarina; Kolbeinsson, Yann; Kyhn, Line A.; Labansen, Aili Lage; Larsen, Martin M.; Lindstrøm, Ulf; Reiertsen, Tone Kristin; Rigét, Frank F.; Roos, Anna; Strand, Jakob; Strøm, Hallvard; Søndergaard, Jens; Sun, Jiachen; Teilmann, Jonas; Therkildsen, Ole Roland; Thórarinsson, Thorkell Lindberg; Tjørnløv, Rune Skjold; Wilson, Simon; Eulaers, Igor (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-24)
      A wide range of species, including marine mammals, seabirds, birds of prey, fish and bivalves, were investigated for potential population health risks resulting from contemporary (post 2000) mercury (Hg) exposure, using novel risk thresholds based on literature and de novo contamination data. The main geographic focus is on the Baltic Sea, while data from the same species in adjacent waters, such ...

      There has been a considerable number of reports on Hg concentrations in Arctic mammals since the last Arctic Monitoring and Assessment Programme (AMAP) effort to review biological effects of the exposure to mercury (Hg) in Arctic biota in 2010 and 2018. Here, we provide an update on the state of the knowledge of health risk associated with Hg concentrations in Arctic marine and terrestrial mammal ...

      Zoonotic infections transmitted from marine mammals to humans in the Baltic and European Arctic are of unknown significance, despite given considerable potential for transmission due to local hunt. Here we present results of an initial screening for <i>Brucella</i> spp. in Arctic and Baltic seal species. Baltic ringed seals (<i>Pusa hispida</i>, n = 12) sampled in October 2015 and Greenland Sea harp ...
