    • Circum-Arctic distribution of chemical anti-herbivore compounds suggests biome-wide trade-off in defence strategies in Arctic shrubs

      Spatial variation in plant chemical defence towards herbivores can help us understand variation in herbivore top–down control of shrubs in the Arctic and possibly also shrub responses to global warming. Less defended, non-resinous shrubs could be more influenced by herbivores than more defended, resinous shrubs. However, sparse field measurements limit our current understanding of how much of the ...

    • Northern expansion is not compensating for southern declines in North American boreal forests 

      Rotbarth, Ronny; Van Nes, Egbert H.; Scheffer, Marten; Jepsen, Jane Uhd; Vindstad, Ole Petter Laksforsmo; Xu, Chi; Holmgren, Milena (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-06-08)
      Climate change is expected to shift the boreal biome northward through expansion at the northern and contraction at the southern boundary respectively. However, biome-scale evidence of such a shift is rare. Here, we used remotely-sensed tree cover data to quantify temporal changes across theNorth American boreal biome from 2000 to . 2019. We reveal a strong northsouth asymmetry in tree cover change, ...
