Competition and soil conditions limit the growth of High Arctic non‐native plants

open access: yesOikos, EarlyView.
Non‐native vascular plant species in the High Arctic are currently restricted mainly to settlements and other anthropogenically disturbed areas. The reasons for this remain unclear, but climate or dispersal do not appear to be the main limiting factors. Instead, biotic interactions combined with soil conditions may play important roles.

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

open access: yesOikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.
