Global variation in above-ground traits is described in the <i>global spectrum of form and function</i>, which differentiates two principal axes of trait variation. The first contrasts <i>fast</i>, <i>resource-acquisitive</i> strategies with <i>slow</i>, <i>resource-conserving</i> strategies (Wright et al., <span>2004</span>), and the second is related to plant and seed size (Díaz et al., <span>2016</span>; Reich, <span>2014</span>). Additional strategy axes have also been described for below-ground traits, with the <i>collaboration</i> axis describing a gradient of strategies for acquiring soil resources. This ranges from plants with a <i>do-it-yourself</i> strategy that acquire resources via direct root uptake to species <i>outsourcing</i> resource acquisition by forming relationships with mycorrhizal fungi (Bergmann et al., <span>2020</span>; Weigelt et al., <span>2021</span>).</p>\u0000<p>There is evidence that the major axes of functional strategy variation, initially described for individual species, can also manifest at the community level. This is due to habitat filtering selecting for consistent traits across multiple species of a community (Bruelheide et al., <span>2018</span>). These community-level trait responses are often described using abundance-weighted mean trait values (CWMs). CWMs have been shown to vary in response to environmental gradients across scales. For instance, at a global level, CWMs of plant traits related to a <i>conservative</i> strategy are closely correlated with precipitation gradients, while traits associated with plant size and nutrient acquisition are strongly linked to temperature (Bouchard et al., <span>2024</span>; Joswig et al., <span>2022</span>; Moles et al., <span>2014</span>; Xu et al., <span>2023</span>). Additionally, at the regional scale, Li et al. (<span>2017</span>) observed strong associations between precipitation and CWM root traits related to mycorrhizal colonization, whereas at the local scale, Schellenberger Costa et al. (<span>2017</span>) observed a positive relationship between <i>resource-acquisitive</i> traits and precipitation.</p>\u0000<p>As plant traits can affect the rate of biogeochemical processes (Chacón-Labella et al., <span>2023</span>), both climate and variation in community-level strategies can influence ecosystem functioning (Freschet et al., <span>2010</span>; Neyret et al., <span>2024</span>; Reich, <span>2014</span>).
