Responses of moist non-acidic arctic tundra to altered environment: productivity, biomass, and species richness (2003, background): “2002), 15 years in moist acidic tundra (Shaver et al. 2001)), one or two species came to dominate the community in such a way that other species were excluded.”
Luxury consumption of soil nutrients: a possible competitive strategy in above‐ground and below‐ground biomass allocation and root morphology for slow‐growing arctic vegetation? (2003, background): “The community differs from the more commonly investigated moist acidic tussock tundra (e.g. Chapin et al. 1993; Shaver et al. 2001) because of its soil pH, soil nutrients and its greater species diversity and lower shrub abundance.”
AN INTRODUCED PREDATOR ALTERS ALEUTIAN ISLAND PLANT COMMUNITIES BY THWARTING NUTRIENT SUBSIDIES (2006, background): “…found that graminoids are favored under high fertilization conditions (Aerts and Berendse 1988, Wedin and Tilman 1996), although in higher latitude arctic tundra fertilization sometimes favors woody shrubs such as Salix spp. and Betula nana over grasses (Shaver et al. 2001, Mack et al. 2004).”
How do nutrients and warming impact on plant communities and their insect herbivores? A 9‐year study from a sub‐Arctic heath (2002, neutral): “Two other directly comparable studies have been undertaken at an open heath site in the Abisko area of Scandinavia (Jonasson et al. 1999; Graglia et al. 2001), and a tussock tundra site in Alaska (Chapin et al. 1995; Shaver et al. 2001).”
Increased plant productivity in Alaskan tundra as a result of experimental warming of soil and permafrost (2012, methodology): “We did not detect a positive warming effect on deciduous shrub production, as has been found in long-term nutrient experiments (Chapin & Shaver 1996; Shaver et al. 2001); however, a warming-mediated decrease inB. nana foliar d15N indicates a shift in N dynamics, which may, over longer timescales,…”
Nutrient co-limitation of primary producer communities. (2011, background): “Tundra plant community response to N and P addition increased over 15 years accompanied by strong shifts in species dominance (Shaver et al. 2001).”
Primary and secondary stem growth in arctic shrubs: implications for community response to environmental change (2002, methodology): “Under fertilization, whole-plant photosynthesis is higher because of increased leaf area (Bret-Harte et al. 2001; Shaver et al. 2001).”
Interactive effects of anthropogenic nitrogen enrichment and climate change on terrestrial and aquatic biodiversity (2013, background): “For example, in tundra ecosystems in Alaska where increasing temperature is likely to increase N availability further, impacts on biodiversity are likely to accelerate (Chapin et al. 1995; Chapin and Shaver 1996; Shaver et al. 2001).”
Ecosystem feedbacks and cascade processes: understanding their role in the responses of Arctic and alpine ecosystems to environmental change (2009, background): “Leaves have greater concentrations of N than woody stems (Shaver et al., 2001) because of the greater concentration of rubisco in leaves and lignin in stems, so the overall concentration of N in aboveground biomass reflects the relative abundance of leaf vs.”
Plant and soil responses to neighbour removal and fertilization in Alaskan tussock tundra (2004, background): “The change in control plots between 1997 and 1999 is within the range of year-to-year variability previously observed in control tussock tundra at Toolik Lake (Shaver et al. 2001).”
Long‐term experimental manipulation of climate alters the ectomycorrhizal community of Betula nana in Arctic tundra (2011, background): “It is the strongest competitor for soil N (Bret-Harte et al., 2008), increasingly dominates fertilized tussock tundra in long-term experiments (Chapin et al., 1995; Shaver et al., 2001; Mack et al., 2004), and shows positive growth responses to warming treatments (Chapin et al., 1995).”
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”
Stress tolerance and biotic interactions determine plant zonation patterns in estuarine marshes during seedling emergence and early establishment (2011, background): “cover) are dependent on plant architecture (Shaver et al. 2001): Plants with large leaves (e.”
Temperature modulates intra-plant growth of Salix polaris from a high Arctic site (Svalbard) (2013, background): “Positive 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.…”
Arctic warming on two continents has consistent negative effects on lichen diversity and mixed effects on bryophyte diversity (2012, background): “…soil nutrient mineralization (Rustad et al., 2001), bigger and faster-growing vascular plant species might outcompete lichens and at least some of the bryophytes, leading to drastic changes in plant community composition (cf. Chapin & Shaver, 1985; Molau & Alatalo, 1998; Shaver et al., 2001).”
