(Journal article; Tidsskriftartikkel; Peer reviewed, 2020-03-20)
    Understanding the effects of human exploitation on the genetic composition of wild populations is important for predicting species persistence and adaptive potential. We therefore investigated the genetic legacy of large-scale commercial harvesting by reconstructing, on a global scale, the recent demographic history of the Antarctic fur seal (Arctocephalus gazella), a species that was hunted to the ...
  • Sami knowledge and ecosystem-based adaptation strategies for managing pastures under threat from multiple land uses 

    Hausner, Vera Helene; Engen, Sigrid; Brattland, Camilla; Fauchald, Per (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-12-13)
    Ecosystem‐based adaptation (EbA) relies upon the capacity of ecosystems to buffer communities against the adverse impacts of climate change. Maintaining ecosystems that deliver critical services to communities can also provide co‐benefits beyond adaptation, such as climate mitigation and protection of biological diversity and livelihoods. EbA has, to a limited extent, drawn upon indigenous and local ...

    The marine CO<sub>2</sub> system in Tempelfjorden (Svalbard) was investigated between August 2015 and December 2017 using total alkalinity, pH, temperature, salinity, oxygen isotopic ratio, and nutrient data. Primary production resulted in the largest changes that were observed in the partial pressure of CO<sub>2</sub> (<i>p</i>CO<sub>2</sub>, 140 μatm) and the saturation state of aragonite ...
  • Maternal Photoperiodic Programming: Melatonin and Seasonal Synchronization Before Birth 

    van Dalum, Jayme; Melum, Vebjørn Jacobsen; Wood, Shona Hiedi; Hazlerigg, David (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-01-10)
    This mini-review considers the phenomenon of maternal photoperiodic programming (MPP). In order to match neonatal development to environmental conditions at the time of birth, mammals use melatonin produced by the maternal pineal gland as a transplacental signal representing ambient photoperiod. Melatonin acts via receptors in the fetal pituitary gland, exerting actions on the developing medio-basal ...
