Relative climatic, edaphic and management controls of plant functional trait signatures (2009, methodology): “As mean trait values can have different relationships with environmental variables to those of weighted mean values, the analysis was repeated with unweighted mean trait values to assess this impact (Cingolani et al. 2007; Pakeman et al. 2008).”
Being John Harper: Using evolutionary ideas to improve understanding of global patterns in plant traits (2018, background): “Studies with large geographic and taxonomic scope generally find a strong positive relationship between seed mass and rainfall (Gallagher & Leishman, 2012; Moles et al., 2005, 2014; Pakeman et al., 2008; Sandel et al., 2010; Swenson et al., 2012; Swenson & Weiser, 2010).”
Which results of the standard test for community‐weighted mean approach are too optimistic? (2018, methodology): “…0.6 1 CA1 scores 0 5 10 15 20 (e) 'Max' permutation test Number of samples 25 50 100 200 400 800 0 5 10 15 20 (f) then be related to the same sample attributes, and the effect size (correlation coefficient, R2) and its significance (tested by standard tests) can be compared (Pakeman et al., 2008).”
A trait-based approach to comparative functional plant ecology: concepts, methods and applications for agroecology. A review (2012, background): “…on traits (Moles et al. 2005a; Watanabe et al. 2007; Flores et al., submitted manuscript), (3) the relationships between plant traits and environmental factors at continental or global scales (Reich and Oleksyn 2004; Moles et al. 2005a; Pakeman et al. 2008; Moles et al. 2009; Ordoñez et al. 2009).”
Plant traits co-vary with altitude in grasslands and forests in the European Alps (2010, background): “Similarly, Pakeman et al. (2008) showed that seed mass was negatively correlated with latitude and positively correlated with solar radiation; there were significant, negative correlations with temperature and degree-days only when seed mass was not weighted by abundance.”
Community assembly along a soil depth gradient: contrasting patterns of plant trait convergence and divergence in a Mediterranean rangeland (2012, unknown): “For the 26 most abundant species (i.e. representing over 80% of cover; Pakeman et al. 2008), leaves were sampled in June 2009 on at least 12 individuals per species distributed across 4–12 plots.”
