  • sparrow-group-fieldwork How the house sparrow came to be 10. aug. 2018

    How is it that the small, charismatic house sparrow has become so closely associated with us? CEES researchers have been trying to answer this question by sequencing the DNA of populations of sparrows from across Europe and the Middle East. New publication published in Proceedings of the Royal Society of London B.

  • Sanne Boessenkoel, Bastiaan Star, James H. Barrett Handel med hvalross-elfenben holdt liv i den norrøne bosettingen på Grønland 13. aug. 2018 09:07
    Den norrøne kolonien som ble grunnlagt på Grønland av Eirik Raude rundt år 985, varte i nesten 500 år. Norske og britiske forskere har nå analysert DNA funnet i hvalross-rester fra den tiden og påvist at handel med elfenben fra hvalrossens støttenner var en viktig årsak til at bosettingen var så livskraftig.
  • A walrus rostrum with tusks that can be dated to c. 1200-1400 CE. Ancient DNA reveals the extent of Norse Greenland’s trade in walrus ivory 8. aug. 2018 09:06
    Norwegian and British researchers have analysed DNA from up to 1100 year old walrus remains and confirmed that walrus ivory was a driver for both the success and decline of the old Norse colony of Greenland. They also revealed the shifting patterns of walrus ivory trade in medieval Europe and found traces of a major evolutionary split in the Atlantic walrus population.
  • Mørk jordhumle: Får hjerneskade av neonikotinoider Insektmidler er bare én av mange trusler mot humlene 9. juli 2018 09:28
    EU har innført et forbud mot fire insektmidler som fører til at humler og andre bier får hjerneskade. – Det neste halvåret skal vi kartlegge hvordan ulike konsentrasjoner av disse stoffene påvirker humlene ved ulike betingelser, sier forsker Anders Nielsen.
  • Adriana Hernandez-Aguilar at work high up in a tropical tree Chimpanzee beds are cleaner than human beds 26. juni 2018 11:27
    Researchers have suspected for a long time that the elaborate beds and nests where the great apes spend the night provide efficient protection against predators and bloodsuckers. “That is certainly true. But the big surprise is that chimpanzee beds are cleaner than most human beds”, says Adriana Hernandez-Aguilar from the CEES.
