Coastal heathland vegetation is surprisingly resistant to experimental drought across successional stages and latitude
Haugum, Siri Vatsø; Thorvaldsen, Pål; Vandvik, Vigdis; Velle, Liv Guri (Journal article; Peer reviewed, 2021)In the last decade, several major dwarf-shrub dieback events have occurred in northern European coastal heathlands.

(Journal article; Peer reviewed, 2024)Arctic and alpine tundra ecosystems are large reservoirs of organic carbon1,2. Climate warming may stimulate ecosystem respiration and release carbon into the atmosphere3,4. The magnitude and persistency of this stimulation ... -
Germination and seedling growth of Calluna vulgaris is sensitive to regional climate, heathland succession, and drought
Birkeli, Kristine; Gya, Ragnhild; Haugum, Siri Vatsø; Velle, Liv Guri; Vandvik, Vigdis (Journal article; Peer reviewed, 2023)The coastal heathlands of Northwest Europe are highly valued cultural landscapes, that are critically endangered due to land use and climatic changes, such as increased frequency and severity of drought events. Our study ... -
