Genetic analysis indicates spatial-dependent patterns of sex-biased dispersal in Eurasian lynx in Finland
Herrero, Annika; Klutsch, Cornelya; Holmala, Katja; Maduna, Simo; Kopatz, Alexander; Eiken, Hans Geir; Hagen, Snorre (Peer reviewed; Journal article, 2021-02-19)Conservation and management of large carnivores requires knowledge of female and male dispersal. Such information is crucial to evaluate the population’s status and thus management actions. This knowledge is challenging ... -
Genetic changes caused by restocking and hydroelectric dams in demographically bottlenecked brown trout in a transnational subarctic riverine system
Klutsch, Cornelya; Maduna, Simo; Polikarpova, Natalia; Forfang, Kristin; Aspholm, Paul Eric; Nyman, Tommi; Eiken, Hans Geir; Amundsen, Per-Arne; Hagen, Snorre (Journal article; Peer reviewed, 2019-04-29)Habitat discontinuity, anthropogenic disturbance, and overharvesting have led to population fragmentation and decline worldwide. Preservation of remaining natural genetic diversity is crucial to avoid continued genetic ... -
Genome- and transcriptome-derived microsatellite loci in lumpfish Cyclopterus lumpus: Molecular tools for aquaculture, conservation and fisheries management
Maduna, Simo; Vivian-Smith, Adam; Jónsdóttir, Ólöf Dóra Bartels; Imsland, Albert; Klutsch, Cornelya; Nyman, Tommi; Eiken, Hans Geir; Hagen, Snorre (Peer reviewed; Journal article, 2020-01-17)The lumpfish Cyclopterus lumpus is commercially exploited in numerous areas of its range in the North Atlantic Ocean, and is important in salmonid aquaculture as a biological agent for controlling sea lice. Despite the ... -
Highly contaminated river otters (Lontra canadensis) are effective biomonitors of environmental pollutant exposure
Wainstein, Michelle; Harding, Louisa B.; O'Neill, Sandra M.; Boyd, Daryle T.; Koontz, Fred; Miller, Bobbi; Klutsch, Cornelya; Thomas, Philippe J.; Ylitalo, Gina M. (Peer reviewed; Journal article, 2022-08-16)River otters (Lontra canadensis) are apex predators that bioaccumulate contaminants via their diet, potentially serving as biomonitors of watershed health. They reside throughout the Green-Duwamish River, WA (USA), a ... -
Large-scale genetic admixture suggests high dispersal in an insect pest, the apple fruit moth
Elameen, Abdelhameed; Klutsch, Cornelya; Fløystad, Ida; Knudsen, Geir; Tasin, Marco; Hagen, Snorre; Eiken, Hans Geir (Peer reviewed; Journal article, 2020-08-12)Knowledge about population genetic structure and dispersal capabilities is important for the development of targeted management strategies for agricultural pest species. The apple fruit moth, Argyresthia conjugella ... -
Mitogenomics of the suborder Cottoidei (Teleostei: Perciformes): Improved assemblies, mitogenome features, phylogeny, and ecological implications
Maduna, Simo; Vivian-Smith, Adam; Jónsdóttir, Ólöf Dóra Bartels; Imsland, Albert; Klutsch, Cornelya; Nyman, Tommi; Eiken, Hans Geir; Hagen, Snorre (Peer reviewed; Journal article, 2022-03-02)We determined the mitogenome of Cyclopterus lumpus using a hybrid sequencing approach, and another four closely related species in the Liparidae based on available next-generation sequence data. We found that the mitogenome ... -
Romlig-temporal utvikling i kadaverfunn: Tap av beitedyr i forvaltningsområder og randsoner for rovvilt
Hagen, Snorre; Kniha, David; Strand, Geir-Harald; Klutsch, Cornelya; Hansen, Inger; Baklid, Lisbet H.; Eilertsen, Svein Morten (NIBIO Rapport, Research report, 2024)In Norway, grazing is a natural part of a sustainable use of rangeland, where coexistence with protected carnivores is a challenge. The twofold objective of Norwegian carnivore policy and management is that both grazing ... -
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 (Peer reviewed; Journal article, 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 ... -
Sesongvariasjon i rovviltdrepte reinkadavre: Dokumentasjonsgrad på årstidsbeitene i reindrifta
Hagen, Snorre; Strand, Geir-Harald; Kniha, David; Hansen, Inger; Eilertsen, Svein Morten; Baklid, Lisbet H.; Klutsch, Cornelya (NIBIO Rapport, Research report, 2024)I Norge er reindrift en sesongbasert næring, der reinflokkene utnytter ulike beiteområder avhengig av årstiden. Tap av rein gjennom året er en av de største utfordringene i reindriften. Tapene reduserer produksjon, ... -
