Towards rainy high Arctic winters: How experimental icing and summer warming affect tundra plant phenology, productivity and reproduction

open access: yesJournal of Ecology, Volume 114, Issue 1, January 2026.
Extreme rain‐on‐snow events forming basal‐ice can shape high Arctic plant communities as strongly as summer warming. Icing delays soil warming and early growth but compensatory responses follow, at the cost of reproduction. Summer warming offsets most icing impacts, enhancing growth and reversing phenological delays, though inflorescence remains ...

Long‐Term (37 Year) Changes in Coastal Dune Slack Plant Communities

open access: yesApplied Vegetation Science, Volume 29, Issue 1, January/March 2026.
A 37‐year resurvey of coastal dune slack vegetation shows stable α‐diversity, increased γ‐diversity alongside declining β‐diversity and habitat quality. Despite conservation grazing, communities shifted towards taller, more homogeneous, shrub‐dominated and nutrient‐tolerant assemblages, highlighting the limits of current grazing regimes and the ...
