Impact of Multiple Ecological Stressors on a Sub-Arctic Ecosystem: No Interaction Between Extreme Winter Warming Events, Nitrogen Addition and Grazing
Bokhorst, Stef; Berg, Matty P.; Edvinsen, Guro Kristine; Ellers, Jacintha; Heitman, Amber; Jaakola, Laura; Mæhre, Hanne K; Phoenix, Gareth K.; Tømmervik, Hans; Bjerke, Jarle W. (Journal article; Peer reviewed, 2018-11-30)Climate change is one of many ongoing human-induced environmental changes, but few studies consider interactive effects between multiple anthropogenic disturbances. In coastal sub-arctic heathland, we quantified the impact ... -
Rapid photosynthetic recovery of a snow-covered feather moss and Peltigera lichen during sub-Arctic midwinter warming
Bjerke, Jarle Werner; Bokhorst, Stef; Callaghan, Terry V.; Zielke, Matthias; Phoenix, Gareth K. (Journal article; Peer reviewed, 2013-03-06)Background: Arctic lichens and mosses are covered by snow for more than half the year and are generally considered as being dormant for most of this period. However, enhanced frequency of winter warming events due to climate ... -
Sub-arctic mosses and lichens show idiosyncratic responses to combinations of winter heatwaves, freezing and nitrogen deposition
Bokhorst, Stef; Bjerke, Jarle W.; Phoenix, Gareth K.; Jaakola, Laura; Mæhre, Hanne; Tømmervik, Hans (Peer reviewed; Journal article, 2023-02-25)Arctic ecosystems are increasingly exposed to extreme climatic events throughout the year, which can affect species performance. Cryptogams (bryophytes and lichens) provide important ecosystem services in polar ecosystems ...
