“…Ecology is in the midst of a search for the plant traits that best explain how and why species composition and biodiversity influence ecosystem functioning (Chacón‐Labella et al, 2023; Díaz et al, 2016; Hagan et al, 2023; Loreau, 2010; van der Plas et al, 2020, 2023; Walker et al, 2022). Such traits might be based on important aspects of plant physiology and morphology (Carmona et al, 2021; Reich, 2014), the mechanisms controlling competitive coexistence (Klausmeier et al, 2020; Kraft et al, 2015; Lehman & Tilman, 2000), or the processes that drive fluxes of matter and energy (Furey & Tilman, 2021; Loreau, 2010; Roscher et al, 2004, 2012).…”
