TL;DR: In this paper, the authors synthesized current knowledge on environmental variability across terrestrial, freshwater, and marine Antarctic biomes and related this to the observed biotic patterns, showing that the most important physical driver of Antarctic terrestrial communities is the availability of liquid water, itself driven by solar irradiance intensity.
Journal ArticleDOI
Winter warming events damage sub-Arctic vegetation: consistent evidence from an experimental manipulation and a natural event
Stef Bokhorst,Jarle W. Bjerke,Hans Tømmervik,Terry V. Callaghan,Terry V. Callaghan,Gareth K. Phoenix +5 more
TL;DR: In this article, the authors report findings from observations following a natural event and from experimental studies to show that short (<10 days) extreme winter warming events can cause major damage to sub-Arctic plant communities at landscape scales.
Journal ArticleDOI
Shifts in soil microorganisms in response to warming are consistent across a range of Antarctic environments.

TL;DR: This work finds significant increases in the abundance of fungi and bacteria and in the Alphaproteobacteria-to-Acidobacteria ratio, which could result in an increase in soil respiration and shifts toward generalist bacterial communities following warming weakened the linkage between the bacterial taxonomic and functional richness.
Journal ArticleDOI
Size and structure of bacterial, fungal and nematode communities along an Antarctic environmental gradient
Etienne Yergeau,Stef Bokhorst,Ad H L Huiskes,Henricus T. S. Boschker,Rien Aerts,George A. Kowalchuk +5 more
TL;DR: Examination of soil-borne Antarctic communities provides insight into the main drivers of microbial community size and structure across a range of terrestrial Antarctic and sub-Antarctic habitats, potentially serving as a useful baseline to study the impact of predicted global warming on these unique and pristine ecosystems.
Journal ArticleDOI
Impacts of extreme winter warming in the sub-Arctic : growing season responses of dwarf shrub heathland
Stef Bokhorst,Jarle W. Bjerke,F. W. Bowles,Jerry M. Melillo,Terry V. Callaghan,Terry V. Callaghan,Gareth K. Phoenix +6 more
TL;DR: In this paper, a 1-week long extreme winter warming event was simulated in early March using infrared heating lamps run with or without soil warming cables, and the results demonstrate that a single, short, extreme winter heating event can have considerable impact on bud production, phenology and reproductive effort of dominant plant species within sub-Arctic dwarf shrub heathland.
