  1. 1. On the role of terrestrial ecosystems in a changing Arctic

    Författare :Adrian Gustafson; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Northern high latitudes; Arctic climate change; climate-vegetation feedbacks; shrubs; shrubification; treeline migration; LPJ-GUESS; RCA-GUESS; nitrogen; carbon; Northern high latitudes; Arctic climate change; climate-vegetation feedbacks; shrubs; shrubification; treeline migration; LPJ-GUESS; RCA-GUESS; Nitrogen; Carbon;

    Sammanfattning : The global temperature rise is proportional to the cumulative amount of CO2 emissions to the atmosphere. This observation is consistent between climate models and historical observations. LÄS MER

  2. 2. Impact of climate warming on Arctic plant diversity: phylogenetic diversity unravels opposing shrub responses in a warming tundra

    Författare :Ruud Scharn; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arctic; Oroarctic; Tundra; long-term warming; soil moisture; vegetation change; shrubification; biodiversity; phylogenetic diversity; plant community structure;

    Sammanfattning : The Arctic biome is at significant risk, with recent observations suggesting that climate change is warming the Arctic nearly four times faster than the global average. Last decade, evidence from experimental warming studies and observations of ambient warming over time shows how increasing air temperature in the Arctic has led to changes to arctic vegetation, and encroachment of trees and shrubs into the tundra.

  3. 3. The role of herbivores in mediating responses of tundra ecosystems to climate change

    Författare :Elina Kaarlejärvi; Johan Olofsson; Anu Eskelinen; Jon Moen; Eric Post; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Climate change; warming; grazer; Rangifer; Lemmus lemmus; species distribution; biotic interactions; altitude; Environmental Science; miljövetenskap;

    Sammanfattning : The Arctic areas are warming more rapidly than other parts of the world. Increasing temperatures are predicted to result in shrubification, higher productivity, declining species diversity and new species invasions to the tundra. LÄS MER
