Realistically Low Species Evenness Does Not Alter Grassland Species-Richness-Productivity Relationships (2004, background): “Furthermore, experiments have shown that evenness can be important to grassland primary productivity and invasion resistance (Wilsey and Potvin 2000, Wilsey and Polley 2002).”
An improved model to predict the effects of changing biodiversity levels on ecosystem function (2013, background): “Most of the existing modelling approaches relate ecosystem function to richness as the sole measure of diversity, ignoring community evenness and species’ relative abundances (Chapin et al. 2000; Wilsey & Polley 2002; Kirwan et al. 2007; Hillebrand, Bennett & Cadotte 2008).”
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 .”
Do we protect biological originality in protected areas? A new index and an application to the Bonifacio Strait Natural Reserve (2008, background): “…indices: (i) evenness, which measures the relative distribution of abundance among species and is positively related to resistance against invasion (Wilsey and Polley, 2002); and (ii) functional diversity, which measures the value and range of functional traits in organism assemblages, is now…”
Invasion in space and time: non‐native species richness and relative abundance respond to interannual variation in productivity and diversity (2004, background): “…species evenness while keeping richness constant, dicot invaders were most likely to invade in plots where monocots dominated the community (Wilsey & Polley 2002), indicating that functional identity of the invader can interact with community characteristics of dominance or evenness to…”
Disentangling biodiversity effects on ecosystem functioning: deriving solutions to a seemingly insurmountable problem (2003, background): “Effective BEF research must address distribution and abundance (Wilsey & Polley 2002).”
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 .”
Top predator control of plant biodiversity and productivity in an old‐field ecosystem (2003, background): “Most contemporary studies of the relationship between terrestrial plant diversity and ecosystem function such as productivity usually quantify diversity in terms of species richness (but see e.g. Wilsey & Potvin 2000; Wilsey & Polley 2002).”
DISTURBANCE BY FIRE FREQUENCY AND BISON GRAZING MODULATE GRASSHOPPER ASSEMBLAGES IN TALLGRASS PRAIRIE (2005, background): “For example, increased evenness of vegetation in a plant community with the same species richness resulted in higher densities of spittlebug (Wilsey and Polley 2002).”
Biodiversity-Ecosystem Function Research: Is It Relevant to Conservation? (2005, background): “In BDEF research, biodiversity is most often manipulated or measured as the number of species or genotypes, although a few studies have manipulated evenness (e.g., Wilsey & Polley 2002).”
Dominance not richness determines invasibility of tallgrass prairie. (2004, background): “2002) and evenness (Wilsey and Polley 2002) at small spatial scales and in relatively homogeneous systems.”
Assessing grassland restoration success: relative roles of seed additions and native ungulate activities (2006, background): “In contrast, high dominance may enhance seedling emergence in some grasslands (Wilsey & Polley 2002; Smith et al. 2004).”
Forage productivity, species evenness and weed invasion in pasture communities (2003, background): “Many experiments have reported reduced weed abundance as diversity increases in grassland communities (Crawley et al., 1999; Knops et al., 1999; Lyons and Schwartz, 2001; Naeem et al., 2000; Wilsey and Polley, 2002).”
