  abstract = {{A}im: {T}wo frameworks ({BASVIL} and {PODCAR}), based on two different functional representations (ordination and dendrogram), have been proposed for partitioning overall functional beta diversity into two analogous components: turnover and nestedness-resultant dissimilarity, or replacement and difference of functional richness, respectively. {W}e compared the two frameworks by testing the influence of functional representations and partitioning methods on the measurement of overall functional beta diversity and its components. {I}nnovation: {W}e computed beta-diversity indices from the two frameworks on a set of communities simulated according to five scenarios of assembly: random, richness gradient, pure nestedness, pure turnover and mixed turnover/loss scenarios. {T}o disentangle the effects of the partitioning approach and those of the functional representation on measurement of functional beta diversity, we also computed {PODCAR} indices in multidimensional space. {M}ain conclusions: {BASVIL} and {PODCAR} frameworks led to different results for overall functional beta diversity and their analogous partitioning components. {M}ost of the difference between the two frameworks was due to the functional representation used. {T}he goodness-of-fit measure (mean squared deviation, m{SD}) to assess the quality of functional spaces showed that the one computed on the basis of the dendrogram used in {PODCAR} remained lower than that of the functional ordination considered in {BASVIL}. {I}n addition, only functional turnover derived from the {BASVIL} framework is independent of difference in functional richness. {F}inally, {BASVIL} measured functional variations derived from nested phenomena while {PODCAR} did not allow separation of this variation derived from richness difference. {H}owever, the sensitivity of {BASVIL} to functionally extreme species may make it difficult to know whether variations of the nestedness-resultant dissimilarity components are due to a turnover with few extreme species or a loss in functional richness. {P}articular attention with regard to the properties of the two frameworks is required before drawing conclusions regarding processes that structure communities.},
