 Each model was tested using either (1) an actual phylogenetic hypothesis for one taxon (plants or insects), assuming equal branch lengths (see Methods), or (2) a "starshaped" phylogeny with all species equally related, equivalent to a conventional nonphylogenetic analysis or (3) using reduced major axis (RMA) regression without any phylogenetic adjustment. LCL: lower 95% confidence limit; UCL: upper 95% confidence limit. λ lambda is a measure of phylogenetic correlation (for details of how this is calculated see Halsey et al. 2006); AIC is Akaike's information criterion; w_{i} is the Akaike weight, the probability that the model is the correct one of those tested [67]. RMA confidence limits calculated by bootstrapping (1000 bootstraps) in RMA for JAVA v. 1.21 [63].
