Multiple phosphorus acquisition strategies adopted by fine roots in low-fertility soils in Central Amazonia (2019, methodology): “Bivariate relationships between root morphology properties, root phosphatase activity and AM colonisation were described using Standard Major Axis (SMA) line fits using the package smatr (Warton et al. 2012; Warton et al. 2006).”
Linking functional traits and demographic rates in a subtropical tree community: the importance of size dependency (2014, methodology): “This was done using the slope test function in the smatr R-package (Warton et al. 2012).”
Competition for light and water play contrasting roles in driving diversity–productivity relationships in Iberian forests (2014, methodology): “All analyses were performed in R (3.0.1; R Development Core Team 2013), relying primarily on packages lme4 (Bates et al. 2013), MuMIn (Barton 2013), ordinal (Christensen 2012) and smatr (Warton et al. 2012).”
Using species distribution models to inform IUCN Red List assessments (2014, result): “The slope of this relationship is not different from the one-to-one slope (standardized major axis analysis (SMA; Warton et al. 2012); R²=0.027, slope = 1.007, upper slope CI= 0.906 and lower slope CI= 1.120), indicating that the tendency for the SDM-derived MCPs to be larger than the SRLI sample…”
Maize Nutrient Accumulation and Partitioning in Response to Plant Density and Nitrogen Rate: I. Macronutrients (2013, methodology): “Reduced major axis (RMA), derived through the SMATR package (SMATR version 3; Warton et al., 2012) from the R program, was utilized to evaluate the allometric slopes and intercepts.”
A plant economics spectrum in Mediterranean forests along environmental gradients: is there coordination among leaf, stem and root traits? (2016, unknown): “All these analyses were conducted in the R 2·10·0 statistical platform (R Development Core Team 2011), using the packages “ape” (Paradis et al. 2004), “car” (Fox & Weisberg 2011), “FactoMiner” (Lê et al. 2008), “phytools” (Revell 2012), “smatr” (Warton et al. 2012) and “vegan” (Dixon 2003).”
Light and growth in marine phytoplankton: allometric, taxonomic, and environmental variation (2015, methodology): “Allometric relationships are often fit using standardized major axis (SMA) regression (Warton et al. 2006).”
Body mass estimation in non‐avian bipeds using a theoretical conversion to quadruped stylopodial proportions (2014, methodology): “Line-fitting analyses used ‘smatr’ (Warton et al. 2011) and mass estimations, using cQE, QE, AHR, CM and CF, as well as PPEs and SEEs were generated through the new package ‘MASSTIMATE’ (Appendix S1).”
Linking above- and belowground resource use strategies for native and invasive species of temperate deciduous forests (2015, methodology): “We tested for differences in elevation and slope between fitting lines for each group and a shift between groups along their common axis using the ‘smatr’ package for R (Warton and Warton 2007; Warton et al. 2012).”
Grain Nitrogen Source Changes over Time in Maize: A Review (2013, methodology): “The SMATR package (version 3; Warton et al., 2012) from the R program (R Development Core Team, 2009) was used to test for common slopes and intercepts (Table 2).”
Correction factors for unbiased, efficient estimation and prediction of biomass from log-log allometric models (2013, methodology): “More recently, Warton et al. (2012) released software that offers two alternatives to OLS regression for finding the regression line of best fit, namely 'major axis' and 'standardised major axis'.”
