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): “A non-acidic moist tussock tundra site (Walker et al. 1994; Gough et al. 2000 ) in the vicinity of the Arctic LTER site at Toolik Lake (68 ° 38 ′ N, 149 ° 36 ′ W, 760 m above sea level) on the North Slope of the Brooks Range, Alaska, has been subjected to annual N and P 666 M. T. van Wijk et al.”
The Rengen Grassland Experiment: Plant species composition after 64 years of fertilizer application (2007, background): “This agrees with Gough et al. (2000) who recorded higher species richness on soils with a higher pH.”
Relationships between productivity, number of shoots and number of species in bryophytes and vascular plants (2001, background): “successional age or edaphic conditions of sites) may also affect productivity and thus the species densitybiomass relationship ( Gough et al . 2000; Loreau 2000).”
Herbivore and neighbour effects on tundra plants depend on species identity, nutrient availability and local environmental conditions (2007, result): “This finding corresponds to the observed lower nutrient availability in acidic sites and may partly explain the general scarcity of forbs in these shrub-dominated, species-poor heaths (Gough et al. 2000; Peet et al. 2003; Nordin et al. 2004).”
Responses of moist non-acidic arctic tundra to altered environment: productivity, biomass, and species richness (2003, methodology): “In late July 1997, above-ground biomass only was harvested from eight 20 x 20 cm quadrats at this site (Gough et al. 2000b), prior to the establishment of the experimental plots described above.”
Plant diversity patterns in semi-natural grasslands along an elevational gradient in southern Norway (2002, background): “This relationship is previously found both in grasslands (Grime 1973; Austrheim et al. 1999) and arctic habitats ( Gough et al. 2000 ).”
Local and regional patterns of species richness in Central European vegetation types along the pH/calcium gradient (2003, background): “…of the Central European Ice Age tundra or cold steppe, soil pH was repeatedly reported to be strongly positively correlated with species richness (GOUGH et al. 2000, WALKER et al. 2001, PÄRTEL 2002), although this relationship can be modified by the effects of other factors (e.g. GOULD & WALKER…”
