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 ... -
Seasonal dynamics of lotic bacterial communities assessed by 16S rRNA gene amplicon deep sequencing
Paruch, Lisa; Paruch, Adam; Eiken, Hans Geir; Skogen, Monica; Sørheim, Roald (Peer reviewed; Journal article, 2020-10-02)Aquatic microbial diversity, composition, and dynamics play vital roles in sustaining water ecosystem functionality. Yet, there is still limited knowledge on bacterial seasonal dynamics in lotic environments. This study ... -
Sex-specific genetic analysis indicates low correlation between demographic and genetic connectivity in the Scandinavian brown bear (Ursus arctos)
Schregel, Julia; Kopatz, Alexander; Eiken, Hans Geir; Swenson, Jon; Hagen, Snorre (Peer reviewed; Journal article, 2017-07-03)The degree of gene flow within and among populations, i.e. genetic population connectivity, may closely track demographic population connectivity. Alternatively, the rate of gene flow may change relative to the rate of ... -
Sociodemographic factors modulate the spatial response of brown bears to vacancies created by hunting
Frank, Shane C.; Leclerc, Martin; Pelletier, Fanie; Rosell, Frank Narve; Swenson, Jon; Bischof, Richard; Kindberg, Jonas; Eiken, Hans Geir; Hagen, Snorre; Zedrosser, Andreas (Journal article; Peer reviewed, 2017-11-13) -
Successful Production and Ligninolytic Activity of a Bacterial Laccase, Lac51, Made in Nicotiana benthamiana via Transient Expression
van Eerde, André; Varnai, Aniko; Wang, Yanliang; Paruch, Lisa; Jameson, John-Kristian; Qiao, Fen; Eiken, Hans Geir; Su, Hang; Eijsink, Vincent; Clarke, Jihong Liu (Peer reviewed; Journal article, 2022-05-13)Giant panda could have bamboo as their exclusive diet for about 2 million years because of the contribution of numerous enzymes produced by their gut bacteria, for instance laccases. Laccases are blue multi-copper oxidases ... -
Testing hair sampling on power poles as a potential method for DNA identification and monitoring brown bears
Kopatz, Alexander; Aspholm, Paul Eric; Rudolph, Anja; Eiken, Hans Geir; Schregel, Julia; Aarnes, Siv; Tobiassen, Camilla; Hagen, Snorre (Bioforsk rapport;9(168) 2014, Research report, 2014-12-05)Genetic methods based on sampling of feces and hairs to study brown bears have become the method of choice for many wildlife researchers and managers. Feces and hairs are the most common sample material for DNA identification ... -
Undersøkelse av antibiotikaresistensmarkørgenet nptII i norsk natur. Analyserapport: Forekomst av antibiotikaresistensmarkørgenet neomycin fosfotransferase II (nptII) i prøver fra 12 ville arter fra Norge
Forfang, Kristin; Hagen, Snorre; Elameen, Abdelhameed; Fløystad, Ida; Eiken, Hans Geir (NIBIO Rapport;4(100) 2018, Research report, 2018-08-15)Undersøkelse av antibiotikaresistensmarkørgenet neomycin fosfotransferase II (nptII) i prøver fra 12 ville arter fra Norge I et prosjekt fra Miljødirektoratet har vi testa for tilstedeværelse av nptII genet i 219 prøver ...
