Plant trait- based ecology is a powerful extension of the attempt of community ecolo -gists to unveil assembly mechanisms. However, the two main expected determinants of community assembly, niche and neutral processes, can be confused under this framework. Here, we propose to move from trait- based to phenotype- based commu-nity ecology, accounting for the variation between individuals (phenotypes affected by the abiotic and biotic environment, and vice versa), and explicitly considering their ability to compete with or facilitate its neighbours. This would shift our focus from species' niche responses to niche specialization of phenotypes, reducing the space for neutrality at the finest scales. The current assembly framework, based mainly on niche complementarity and using species-average functional traits, has been devel -oped exploring mega- diverse communities, but it fails at describing poor plant com -munities. Under this framework, monospecificity would be interpreted as an arena where functionally similar individuals compete, consequently leading to regular pat -terns, which are rarely found in nature. Our niche specialization framework could help explaining coexistence in rich plant communities, where the higher fraction of functional variation is found between species, whereas the intraspecific trait varia -tion dominates in poor species and monospecific communities. We propose a guide to conduct massive phenotyping at the community scale based on the use of visible and near- infrared spectroscopy. We also discuss the need to integrate the so- called plant's eye perspective based on the use of spatial pattern statistics in the current community ecology toolbox. ; This work was supported by the Ministerio de Economía y Competitividad of the Spanish Government [PHENOTYPES PGC2018-099115-B-I00] and by Comunidad de Madrid Government [REMEDINAL-TE- CM P2018/EMT-4338]. ; Peer reviewed
