Miller, Andrea L.; Evans, Alina L.; Os, Øystein; Arnemo, Jon Martin (Journal article; Peer reviewed, 2013)Hematologic and serum biochemistry values were evaluated in free-ranging, wild Norwegian reindeer (Rangifer tarandus tarandus) as part of a reintroduction program in southwestern Norway in November 1995 and 1996. Animals ... -
Body Temperature during Hibernation Is Highly Correlated with a Decrease in Circulating Innate Immune Cells in the Brown Bear (Ursus arctos): A Common Feature among Hibernators?
Sahdo, Berolla; Evans, Alina L.; Arnemo, Jon Martin; Fröbert, Ole; Särndahl, Eva; Blanc, Stéphane (Journal article; Peer reviewed, 2013)Background: Hibernation involves periods of severely depressed metabolism (torpor) and decreases in body temperature (Tb). Small arctic mammals (<5kg), in which Tb generally drop drastically, display leukopenia during ... -
Capture, Anesthesia, and Disturbance of Free-Ranging Brown Bears (Ursus arctos) during Hibernation
Evans, Alina L.; Sahlén, Veronica; Støen, Ole-Gunnar; Fahlman, Åsa; Brunberg, Sven; Madslien, Knut; Fröbert, Ole; Swenson, Jon E.; Arnemo, Jon Martin (Journal article; Peer reviewed, 2012)We conducted thirteen immobilizations of previously collared hibernating two- to four-year-old brown bears (Ursus arctos) weighing 21–66 kg in central Sweden in winter 2010 and 2011 for comparative physiology research. ... -
Evaluation of Medetomidine-Ketamine and atipamezole for reversible anesthesia of free-ranging gray wolves (Canis lupus)
Arnemo, Jon Martin; Evans, Alina L.; Ahlqvist, Per; Segerström, Peter; Liberg, Olof (Journal article; Peer reviewed, 2013)Twenty-eight anesthetic events were carried out on 24 free-ranging Scandinavian gray wolves (Canis lupus) by darting from a helicopter with 5 mg medetomidine and 250 mg ketamine during winter in 2002 and 2003. Mean6SD ... -
Evidence of alphaherpesvirus infections in Alaskan caribou and reindeer
Evans, Alina L.; Neves, Garlos G. das; Finstad, Greg; Beckmen, Kimberlee B.; Skjerve, Eystein; Nymo, Ingebjørg H.; Tryland, Morten (Journal article; Peer reviewed, 2012)Background: The reindeer (Rangifer tarandus tarandus) industry in Alaska began with animals imported from Siberia (Russia) in the 1890’s. Cervid herpes virus 2 (CvHV2) is endemic in reindeer in Scandinavia. We sought ... -
Haematological and biochemical reference intervals for free-ranging brown bears (Ursus arctos) in Sweden
Græsli, Anne Randi; Fahlman, Åsa; Evans, Alina L.; Bertelsen, Mads Frost; Arnemo, Jon Martin; Nielsen, Søren Saxmose (Journal article; Peer reviewed, 2014)Background: Establishment of haematological and biochemical reference intervals is important to assess health of animals on individual and population level. Reference intervals for 13 haematological and 34 biochemical ... -
Hematology and serum chemistry reference ranges of free-ranging moose (Alces Alces) in Norway
Rostal, Melinda K.; Evans, Alina L.; Solberg, Erling L.; Arnemo, Jon Martin (Journal article; Peer reviewed, 2012)Baseline reference ranges of serum chemistry and hematology data can be important indicators for the status of both individuals or populations of wild animals that are affected by emerging pathogens, toxicants, or other ... -
Hydrogen sulfide and nitric oxide metabolites in the blood of free-ranging brown bears and their potential roles in hibernation
Revsbech, Inge G; Shen, Xinggui; Chakravarti, Ritu; Jensen, Frank B.; Thiel, Bonnie; Evans, Alina L.; Kindberg, Jonas; Fröbert, Ole; Stuehr, Dennis J.; Kevil, Christopher G.; Fago, Angela (Journal article; Peer reviewed, 2014)During winter hibernation, brown bears (Ursus arctos) lie in dens for half a year without eating while their basal metabolism is largely suppressed. To understand the underlying mechanisms of metabolic depression in ... -
