Finally, plot-level metrics of effect traits were related to response traits and the species composition of plant communities.Įach cushion-forming species had a distinctive combination of effect traits and harboured a unique plant community with an exclusive composition of response traits. Traits were measured at the individual level and then aggregated to trait metrics (mean, range, dispersion) at the plot level. In a field study, we addressed the specificity of plant–plant interactions by quantifying effect traits of three co-occurring cushion-forming species and response traits of their associated plant assemblages. response traits) might explain plant–plant interactions and their role in community assembly. effect traits) and those known to respond to the environment (i.e. Here we asked whether analysing spatial associations between plant traits known to affect the environment (i.e. Even though such specificity in plant interactions is common and known, there is no empirical assessment of the mechanisms that would help us understand its importance for plant diversity. In plant communities, the presence of a species has consequences for other species, with some being competitively excluded while others benefit from the close vicinity of neighbours.
