    • The eyes of the deep diving hooded seal (Cystophora cristata) enhance sensitivity to ultraviolet light 

      Hogg, Chris; Neveu, Magella; Folkow, Lars; Stokkan, Karl-Arne; Kam, Jaimie Hoh; Douglas, Ron H; Jeffery, Glen (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-05-11)
      The mammalian visual range is approximately 400–700 nm, although recent evidence suggests varying ultraviolet (UV) extensions in diverse terrestrial species. UV sensitivity may have advantages in the dim, blue light shifted environment experienced by submerged marine mammals. It may also be advantageous when seals are on land as UV is reflected by snow and ice but absorbed by fur, enhancing visual ...

    • Shifting mirrors: adaptive changes in retinal reflections to winter darkness in Arctic reindeer 

      Stokkan, Karl-Arne; Folkow, Lars; Dukes, Juliet; Neveu, Magella; Hogg, Chris R; Siefken, Sandra Katharina Christiane; Dakin, Steven C; Jeffery, Glen (Journal article; Tidsskriftartikkel; Peer reviewed, 2013-12-22)
      Arctic reindeer experience extreme changes in environmental light from continuous summer daylight to continuous winter darkness. Here, we show that they may have a unique mechanism to cope with winter darkness by changing the wavelength reflection from their tapetum lucidum (TL). In summer, it is golden with most light reflected back directly through the retina, whereas in winter it is deep ...
