prepR4pcm: An R package for preparing data and trees for phylogenetic comparative methods

Phylogenetic comparative methods require species names in a trait dataset to match tip labels in a phylogenetic tree. Yet this apparently simple prerequisite is often one of the most fragile steps in a comparative workflow. Names may differ because of, for example, formatting, ta...

Mate choice copying in non-human animals: An update of two meta-analyses

Mate choice copying, the use of social information from others' mating decisions, is a taxonomically widespread form of social learning that can shape sexual selection. Two meta-analyses concluded that social information has a moderate positive effect on mate choice, but both res...

Mastering a simulation-based parametric method to obtain bias-corrected point estimates and sampling variance for effect sizes

Abstract Meta-analyses require an effect-size estimate and its corresponding sampling variance from primary studies. For some effect size statistics, however, estimators of sampling variance are unavailable, requiring new derivations. Traditionally, such formulas are obtained usi...
