    • Activity patterns in mammals: Circadian dominance challenged 

      Hazlerigg, David; Tyler, Nicholas J. C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-15)
      The evidence that diel patterns of physiology and behaviour in mammals are governed by circadian ‘clocks’ is based almost entirely on studies of nocturnal rodents. The emergent circadian paradigm, however, neglects the roles of energy metabolism and alimentary function (feeding and digestion) as determinants of activity pattern. The temporal control of activity varies widely across taxa, and ungulates, ...

    • Behavioural Responses of Moulting Barnacle Geese to Experimental Helicopter Noise and a Predator 

      Tyler, Nicholas J. C.; Jacobsen, Karl-Otto; Blix, Arnoldus S (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      The response of animals to anthropogenic noise can be aggravated by lack of familiarity with its auditory pattern and also by nervousness characteristic of particular phases of their life cycle. Both conditions apply in the Arctic where human activity is highly localised and field operations, being largely restricted to summer, coincide with the period when animals produce and nurse offspring and, ...

    • The shrinking resource base of pastoralism: Saami reindeer husbandry in a climate of change 

      Tyler, Nicholas J. C.; Hanssen-Bauer, Inger; Førland, Eirik J.; Nellemann, Christian (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-10)
      The productive performance of large ungulates in extensive pastoral grazing systems is modulated simultaneously by the effects of climate change and human intervention independent of climate change. The latter includes the expansion of private, civil and military activity and infrastructure and the erosion of land rights. We used Saami reindeer husbandry in Norway as a model in which to examine ...
