An assessment of grassland restoration success using species diversity components (2005, background): “High evenness can increase invasion resistance, total and below-ground productivity, and can reduce local plant extinction rates (Wilsey & Potvin 2000; Wilsey & Polley 2002, 2004; Smith et al .”
Extinction order and altered community structure rapidly disrupt ecosystem functioning. (2005, background): “However, when rare species are the most extinction prone, communities may lose function much less rapidly than we found in this study, as has been found for the non-random loss of some plant species (Wilsey & Polley 2004).”
Patterns of Plant Species Diversity in Remnant and Restored Tallgrass Prairies (2005, background): “Low levels of evenness, however, may indirectly reduce species richness by increasing the rate of local extinctions (Wilsey & Polley 2004).”
Dominant Species Constrain Effects of Species Diversity on Temporal Variability in Biomass Production of Tallgrass Prairie (2007, background): “The exponential coefficient of these rank-abundance relationships (b) equals the slope of the negative relationship between the natural logarithm of relative abundance and rank and thus is an index of how equitably biomass is distributed among species (Wilsey and Polley 2004).”
Relationships Among Indices Suggest that Richness Is an Incomplete Surrogate for Grassland Biodiversity (2005, background): “…can have important effects on net primary productivity, invasion resistance , and local extinction (Nijs and Roy 2000, Wilsey and Potvin 2000, Foster et al. 2002, Wilsey and Polley 2002, Smith and Knapp 2003, Smith et al. 2004, Wilsey and Polley 2004) that are independent of species richness .”
Species richness and evenness respond in a different manner to propagule density in developing prairie microcosm communities (2007, unknown): “Species included in the experiment were: the C 4 grasses Plant relative abundances typically vary greatly among species in a community (Grime 1998; Hubbell 2001; Magurran 2004; Wilsey and Polley 2004 ), and species can vary in their reproduction and colonization rates.”
Species richness effects on ecosystem multifunctionality depend on evenness, composition and spatial pattern (2012, background): “…maximal evenness (equal distribution of cover among species, 30% each in two-species mixtures, 15% each in four- species mixtures, and 7.5% each in eight-species mixtures) or a more realistically low evenness based on a geometric distribution of abundances among species (Wilsey & Polley 2004).”
An improved model to predict the effects of changing biodiversity levels on ecosystem function (2013, background): “…et al. 2004; Roscher et al. 2005; Kirwan et al. 2007; Weigelt et al. 2008); community evenness (Wilsey & Potvin 2000; Polley, Wilsey & Derner 2003; Wilsey & Polley 2004; Kirwan et al. 2007; Hillebrand, Bennett & Cadotte 2008; Isbell et al. 2008; Isbell, Polley & Wilsey 2009; Wittebolle et al.…”
Consequences of dominance: a review of evenness effects on local and regional ecosystem processes. (2008, background): “As an example, Wilsey and Potvin (2000) analyzed the effects of evenness on plant productivity in an old field in Quebec and found a positive evenness– productivity relationship irrespective of the identity of the dominant species.”
Biodiversity and Ecosystem Functioning (2014, background): “Experimental manipulation of evenness tends to have either positive or neutral effects on biomass production and associated ecosystem-level responses (Hillebrand et al. 2008, Kirwan et al. 2007, Wilsey & Polley 2004, Wilsey & Potvin 2000, Wittebolle et al. 2009).”
Crop Species Diversity Affects Productivity and Weed Suppression in Perennial Polycultures under Two Management Strategies (2008, unknown): “The Berger–Parker dominance index, which represents the proportion of whole plot biomass produced by the dominant species, was calculated for each plot ( Wilsey and Polley, 2004 ).Values of the dominance index close to one indicate communities that are dominated by a single species.”
