Species composition interacts with fertilizer to control long-term change in tundra productivity (2001, unknown): “Betula grew taller because it produced thicker, stronger woody stems, and because its more rapid branching took place relatively high up on those stems (Bret-Harte et al. 2001).”
How do nutrients and warming impact on plant communities and their insect herbivores? A 9‐year study from a sub‐Arctic heath (2002, background): “© 2002 British Ecological Society, Journal of Ecology, 90, 544–556 light at the expense of slower-growing species of lower stature (Bret-Harte et al. 2001).”
Arctic warming on two continents has consistent negative effects on lichen diversity and mixed effects on bryophyte diversity (2012, background): “From early spring (after snow melt) to autumn, transparent greenhouses gave passive warming (details in Bret-Harte et al., 2001).”
Plant and soil responses to neighbour removal and fertilization in Alaskan tussock tundra (2004, background): “Long-term fertilization experiments in tundra show dramatic changes in the relative dominance of different species, suggesting that competition for light, at least, is important under increased nutrient availability (Bret-Harte et al. 2001; Shaver et al. 2001).”
Dynamics of aboveground phytomass of the circumpolar Arctic tundra during the past three decades (2012, background): “…(Tape et al 2006, Lantz et al 2009, 2010, Blok et al 2010, 2011, Naito and Cairns 2011) most likely leads to large increases in aboveground biomass (Bret-Harte et al 2001), although there have not yet been any comprehensive assessments of the potential biomass implications of this phenomenon.”
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).”
Responses of moist non-acidic arctic tundra to altered environment: productivity, biomass, and species richness (2003, background): “For example, in a detailed analysis of three shrub species in Alaskan moist acidic tundra, Bret-Harte et al. (2001) found that all three species increased growth in response to added nutrients, but only one, Betula nana, was able to translate that growth into increased canopy biomass and thus outcom”
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).”
STRUCTURALLY NOVEL BIOMES: A RESPONSE TO PAST WARMING IN BERINGIA (2005, background): “The large growth-form responses of Salix and Betula species in controlled growth experiments (e.g., seasonal temperature and moisture availability; Bret-Harte et al. 2001, Xiao 2001; K. Schwaegerle, personal communication) illustrate the potential importance of phenotypic responses to future…”
Ecosystem feedbacks and cascade processes: understanding their role in the responses of Arctic and alpine ecosystems to environmental change (2009, background): “As a result, B. nana can branch much more rapidly than other shrub species, creating new sinks for resources and more rapid growth (Bret-Harte et al. 2001).”
Recent expansion of erect shrubs in the Low Arctic: evidence from Eastern Nunavik (2012, background): “The growth response of B. nana appears to be linked to its ability to produce both long and short shoots and to its developmental plasticity in secondary growth (Bret-Harte et al 2001).”
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).”
