  abstract = {{T}he functional trait composition of plant communities reflects the influence of ecological constraints on their assembly. {I}n high-elevation peatlands of the {A}ndes, multiple abiotic and biotic stresses are exerted on herbaceous plant communities. {W}e hypothesized that dominant cushion-plant species found in these ecosystems strongly influence the dynamics of their subordinate plants by providing protection against external stress. {T}o test the hypothesis, we addressed the variation of functional traits reflecting how subordinate plants invest in durable tissues and develop below and above the canopy of two cushion-plant species dominating the ecosystem, with varying intensity of herbivore pressure. {W}e expected different functional composition of plants living below (understory stratum) and above (emergent stratum) the canopy, related to cushion-plant protection. {I}n addition, we considered the functional composition of basic morphological guilds, forbs and graminoids, as they invest differently in plant development and respond differently to herbivore pressure. {W}e found contrasted functional compositions among morphological guilds and according to the position relatively to cushion-plant canopy. {T}hese variations support a protective influence of cushion-plants on subordinate plants for both strata, with investment into less costly leaves and a larger stature when protection is greater, depending on cushion-plant species and cushion-plant height. {E}xternal stress mainly affected emergent plants and led to different responses according to the guild. {G}raminoids showed avoidant strategy, while forbs shifted from avoidant to tolerant strategy with increasing herbivore pressure. {B}oth between-species and intraspecific trait variations contributed to explain functional changes of guilds, but the relative contributions depended on morphological guild and stratum. {A} basic trade-off in physiological and morphological variability determined different relative contribution in forbs and graminoids. {W}hile functional ecology classically focuses on the composition of spatially delimited communities, we here underline the need to address separately the functional composition and assembly dynamics of distinct guilds making a community. {I}n addition, our survey is the first to investigate the functional ecology of high-elevation tropical peatlands and provides novel insights into vegetation ecology in this stressful ecosystem.},
