Effect of phylogeny on functional traits variation.
As a previous analysis, to rule out the effect of species phylogeny on the variation in functional traits, we used Bayesian Mixed Linear Models implemented in the package MCMCglmm v1.10 (Hadfield & Nakagawa, 2010) in R Core Team (2020). In this analysis, the ”species” random factor was not significant for any of the generated models (Supplementary information, Table S3), so the variation was explained by the ”site” factor.
