Tree size frequency distributions, plant density, age and community disturbance (2003, background): “site-specific resource availability and limitation, unique species compositions, mortality-recruitment regimes, and duration, periodicity, and magnitude of disturbance (see Enright & Watson 1991; Roberts & Gilliam 1995; Condit et al. 1998; Chave 1999; Kelly et al. 2001; Kelly & Bowler 2002; Stevens”
Does pattern of soil resource heterogeneity determine plant community structure? An experimental investigation (2005, background): “Such studies often confound resource heterogeneity and total resource availability (Collins & Wein 1998a,b), although a recent exception is the work by Stevens & Carson (2002) in which light heterogeneity was not found to control diversity.”
Overstorey tree species regulate colonization by native and exotic plants: a source of positive relationships between understorey diversity and invasibility (2008, background): “The abundance of a resource, rather than the heterogeneity of the resource, can positively influence both species richness and abundance (Stevens & Carson, 2002) or invasion (Jiang & Morin, 2004) of individual species.”
Linking small-scale topography with microclimate, plant species diversity and intra-specific trait variation in an alpine landscape (2015, background): “The relative roles of available energy (mean supply of limiting resources) and heterogeneity (variation in limiting resources) as drivers of species richness have been debated (e.g. Stevens and Carson 2002; Lundholm 2009).”
Establishment limitation reduces species recruitment and species richness as soil resources rise (2004, background): “Tilman (1993) and Wilson & Tilman (2002) showed that recruitment rate falls as soil resources and standing crop biomass rise.”
Secondary forests on anthropogenic soils in Brazilian Amazonia conserve agrobiodiversity (2010, background): “…Clement (1999), id incipiently domesticated, sd semi-domesticated availability and productivity (e.g., Waide et al. 1999; Mittelbach et al. 2001; Stevens and Carson 2002), while others show an unimodal distribution across a productivity gradient, where richness is higher in intermediate levels…”
The response of plant diversity to ecosystem retrogression: evidence from contrasting long‐term chronosequences (2008, background): “Second, it has been proposed that as soil fertility declines, such as happens during retrogression, there is a greater spatial heterogeneity of limiting soil nutrients and that this heterogeneity promotes niche partitioning and therefore vegetation diversity (Tilman 1988, Silvertown 2004; but see S”
No effect of varying soil resource heterogeneity on plant species richness in a low fertility grassland (2007, background): “This is true despite a wide range of scales at which heterogeneity was imposed, from 25 cm (our study), to c. 30–50 cm (Stevens & Carson 2002), c. 0.5–1.5 m (Collins & Wein 1998) and 2 m (Baer et al. 2004).”
Effect of burning and mowing on grass and forb diversity in a long-term grassland experiment (2004, background): “Light availability may be an important determinant of species diversity (Collins et al. 1998; Henry et al. 2002).”
Linking resource availability and heterogeneity to understorey species diversity through succession in boreal forest of Canada (2018, background): “In contrast, the resource quantity hypothesis suggests that light is the most limiting resource for nearly all understorey species, and understorey species diversity is mainly determined by average light levels (Bartels & Chen, 2010; Stevens & Carson, 2002).”
