Response of green alder (Alnus viridis subsp. fruticosa) patch dynamics and plant community composition to fire and regional temperature in north‐western Canada (2010, background): “At fine scales, experimental evidence also shows that climate warming is likely to promote the growth of shrubs (Parsons et al., 1994; Chapin et al., 1995; Bret-Harte et al., 2001, 2002; Walker et al., 2006).”
Plant and soil responses to neighbour removal and fertilization in Alaskan tussock tundra (2004, background): “In previous fertilization experiments in tussock tundra, there was a lag of 2– 3 years before Betula nana increased its branching rate, after which it showed rapid and sustained growth (Bret-Harte et al. 2002).”
State of the climate in 2010 (2011, background): “Several studies have observed increased shrub growth due to artificial warming, although the increases are small and frequently not statistically significant (e.g., Bret-Harte et al. 2002).”
Ecosystem carbon storage in arctic tundra reduced by long-term nutrient fertilization (2004, background): “Nutrient addition greatly increases C stored aboveground by stimulating plant productivity and by shifting species composition from slow-growing species to more productive shrubs that accumulate C in long-lived woody biomas”
Temperature modulates intra-plant growth of Salix polaris from a high Arctic site (Svalbard) (2013, background): “…growth responses to increasing temperature have been observed in various Salix spp and for Betula nana (Jones et al. 1997; Shaver et al. 2001; Bret-Harte et al. 2002; Hill and Henry 2011; Myers-Smith et al. 2011b), as well as in graminoids and forbs (Myers-Smith et al. 2011a; Walker et al.…”
Shrub expansion in tundra ecosystems: dynamics, impacts and research priorities (2011, background): “These increases in cover and height potentially restrict the growth of other plant species by limiting light availability [6, 7, 10, 11].”
Recent expansion of erect shrubs in the Low Arctic: evidence from Eastern Nunavik (2012, background): “Shrub species were also shown to respond positively to experimental warming (Chapin et al 1995, Chapin and Shaver 1996, Hobbie and Chapin 1998, Bret-Harte et al 2001, 2002, Van Wijk 2003, Jonsdottir et al 2005, Wahren et al 2005, Walker et al 2006, Elmendorf et al 2012).”
Soil nitrogen cycling rates in low arctic shrub tundra are enhanced by litter feedbacks (2010, background): “This preferential spring uptake of N by shrubs has been inferred from fertilization studies which show eventual domination by deciduous shrubs after several years of chronic fertilizer addition (Bret-Harte et al. 2002; Chapin et al. 1995).”
An arctic community of symbiotic fungi assembled by long‐distance dispersers: phylogenetic diversity of ectomycorrhizal basidiomycetes in Svalbard based on soil and sporocarp DNA (2012, background): “As a result of warming temperatures, shifts in land surface vegetation have already been observed (e.g. Chapin et al., 1995; Bret-Harte et al., 2002; Stow et al., 2004).”
Shrub expansion at the forest–tundra ecotone: spatial heterogeneity linked to local topography (2012, background): “For example, an increase in temperature is known to enhance decomposition rate and nutrient cycling (Chapin and Shaver 1996, Hobbie 1996, Bret-Harte et al 2001, 2002, Wahren et al 2005).”
