• Determinants of heart rate in Svalbard reindeer reveal mechanisms of seasonal energy management 

      Trondrud, Liv Monica; Pigeon, Gabriel; Albon, Steve; Arnold, Walter; Evans, Alina; Irvine, R. Justin; Król, Elżbieta; Ropstad, Erik; Stien, Audun; Veiberg, Vebjørn; Speakman, John R.; Loe, Leif Egil (Peer reviewed; Journal article, 2021)
      Seasonal energetic challenges may constrain an animal's ability to respond to changing individual and environmental conditions. Here, we investigated variation in heart rate, a well-established proxy for metabolic rate, ...
    • Fat storage influences fasting endurance more than body size in an ungulate 

      Trondrud, Liv Monica; Pigeon, Gabriel; Król, Elżbieta; Albon, Steve; Evans, Alina; Arnold, Walter; Hambly, Catherine; Irvine, R. Justin; Ropstad, Erik; Stien, Audun; Veiberg, Vebjørn; Speakman, John R.; Loe, Leif Egil (Peer reviewed; Journal article, 2021)
      The fasting endurance hypothesis (FEH) predicts strong selection for large body size in mammals living in environments where food supply is interrupted over prolonged periods of time. The Arctic is a highly seasonal and ...
    • Impact of Management on Avian Communities in the Scottish Highlands 

      Newey, Scott; Mustin, Karen; Bryce, Rosalind; Fielding, Debbie; Redpath, Steve; Bunnefeld, Nils; Daniel, Bronwen; Irvine, R. Justin (Journal article; Peer reviewed, 2016)
      The protection of biodiversity is a key national and international policy objective. While pro- tected areas provide one approach, a major challenge lies in understanding how the con- servation of biodiversity can be ...
    • Limitations of recreational camera traps for wildlife management and conservation research: A practitioner’s perspective 

      Newey, Scott; Davidson, Paul; Nazir, Sajid; Fairhurst, Gorry; Verdicchio, Fabio; Irvine, R. Justin; van der Wal, Renè (Journal article; Peer reviewed, 2015)
      The availability of affordable ‘recreational’ camera traps has dramatically increased over the last decade. We present survey results which show that many conservation practitioners use cheaper ‘recreational’ units for ...
    • Stress responses to repeated captures in a wild ungulate 

      Trondrud, Liv Monica; Ugland, Cassandra Regine; Ropstad, Erik; Loe, Leif Egil; Albon, Steve; Stien, Audun; Evans, Alina; Thorsby, Per Medbøe; Veiberg, Vebjørn; Irvine, R. Justin; Pigeon, Gabriel (Peer reviewed; Journal article, 2022)
      While capture-mark-recapture studies provide essential individual-level data in ecology, repeated captures and handling may impact animal welfare and cause scientific bias. Evaluating the consequences of invasive methodologies ...
