On the need for phylogenetic 'corrections' in functional trait-based approaches

摘要: There is considerable uncertainty about if, and when, phylogenetic information needed to answer various ecological questions trait-based studies. It has been recommended that both functional should be combined, some researchers have even suggested for species ‘corrected’ because are not phylogenetically independent. Here, we address these issues by identifying key types of in ecology discussing the utility answering them, either as a correction or combination with traits. Phylogenetic analyses identified essential related evolution adaptations abiotic biotic conditions. However, argue always relevant trait studies, incorporated into without clear justification. relatedness between considered bias corrected, but rather an evolutionary signal allows results interpreted at different scales. Furthermore, if traits conserved, phylogeny can used proxy missing on diversity. We conclude providing guidelines when apply, how interpret, obtained using variety linked
