Handbook of protocols for standardized measurement of terrestrial invertebrate functional traits (2017, unknown): “Sample size is a general issue in trait-based approaches and has already been covered in other publications, although mainly on plants (e.g. Pakeman & Quested 2007; de Bello et al. 2011; Bolnick et al. 2011; Fu et al. 2013; P erez-Harguindeguy et al. 2013).”
Assessing functional diversity in the field - methodology matters! (2007, background): “The biomass ratio hypothesis (Grime 1998) suggests that it is sufficient to take into account the dominant species from a community to capture response to environmental change and effects on key carbon and nutrient cycling processes (Garnier et al. 2004; Pakeman & Quested 2007 ).”
Filtering processes in the assembly of plant communities: Are species presence and abundance driven by the same traits? (2007, result): “Dominants and most minor species were included in the species dataset, representing between 78% and 100% of the relative vegetation cover of the samples, with a mean of 96%, which is in accordance to the sample protocol suggested by Pakeman & Quested (2007).”
Soil fertility induces coordinated responses of multiple independent functional traits (2015, background): “%) of the total basal area in our calculations of CWM traits, substantially more than the recommended 80% (Pakeman & Quested 2007).”
A global meta-analysis of the relative extent of intraspecific trait variation in plant communities. (2015, unknown): “For both within-and among-community analyses, we only included studies that measured traits of species that together made up at least 80% of total community abundance (variously measured as cover, density, biomass, or frequency) as recommended in previous studies (Pakeman & Quested 2007).”
Functional trait metrics are sensitive to the completeness of the species' trait data? (2014, background): “A previous paper (Pakeman & Quested 2007) demonstrated the impact of sampling only the more common species in a system on the calculation of community weighted mean trait values; errors in estimating community weighted means traits were minimal if the commoner species were measured such that the…”
Effects of disturbance intensity on species and functional diversity in a tropical forest (2012, background): “These species belonged to 61 genera and 33 families, and they are the most important species as they are the strongest determinants of ecosystem functioning and ecosystem response to environmental change (Grime 1998; Pakeman & Quested 2007).”
Evidence for scale‐ and disturbance‐dependent trait assembly patterns in dry semi‐natural grasslands (2013, methodology): “Following recommended protocols (Pakeman & Quested 2007), we concentrated on the 60 most abundant species out of the 217 in the entire data set.”
Using species richness and functional traits predictions to constrain assemblage predictions from stacked species distribution models (2015, methodology): “To account for trait range limitation, we calculated percentiles of trait distribution in sites where the 189 species for which trait data were available represented more than 80% of the total vegetation cover (Pakeman & Quested, 2007; see Pottier et al., 2013; Dubuis et al., 2013).”
Abiotic and biotic drivers of biomass change in a Neotropical forest (2017, background): “The community mean trait values weighted by species’ basal area can be accurately determined if it is based on the species that together compose at least 80% of the abundance (Pakeman & Quested 2007), but a higher coverage is needed to accurately determine trait diversity (Pakeman 2014).”
