Root trait responses to drought are more heterogeneous than leaf trait responses (2020, background): “Similarly, evidence suggests that root traits, such as SRL and RTD, are independent of each other and from the leaf economic spectrum (Kramer-Walter et al., 2016).”
Climate and soil nutrients differentially drive multidimensional fine root traits in ectomycorrhizal‐dominated alpine coniferous forests (2020, methodology): “N and P concentrations) and RTD, may be related to the conservation-acquisition tradeoff, that is, RES, in resource uptake (Freschet et al., 2010; Kramer-Walter et al., 2016; Reich, 2014; Roumet et al., 2016).”
Frontiers in root ecology: recent advances and future challenges (2018, background): “The existence of such an acquisition – conservation trade-off, named the root economics spectrum (RES), is however under debate (Valverde-Barrantes and Blackwood 2016; Kramer-Walter et al. 2016;Weemstra et al. 2016).”
Root nutrient concentration and biomass allocation are more plastic than morphological traits in response to nutrient limitation (2017, background): “1993; Hutchings and de Kroon 1994; Larigauderie and Richards 1994), and root branching intensity at the community-level was shown to be highest in low fertility soil (Holdaway et al. 2011; Kramer-Walter et al. 2016).”
Patterns in intraspecific variation in root traits are species‐specific along an elevation gradient (2020, background): “All rights reserved combinations of SRL, root diameter and tissue density values, demonstrating that a range of root trait strategies can co-exist for plants to adjust uptake strategies (Bergmann et al., 2020; Kramer-Walter et al., 2016; McCormack & Iversen, 2019).”
A hyper‐arid environment shapes an inverse pattern of the fast–slow plant economics spectrum for above‐, but not below‐ground resource acquisition strategies (2018, background): “…of coordination between root and leaf traits can be multidimensional, meaning that certain root traits are coordinated with leaf traits, while others vary independently in determining resource acquisition strategies (Butterfield et al., 2017; Fort, Jouany, & Cruz, 2013; Kramer-Walter et al., 2016).”
