Passerine sister clade comparisons reveal variable macroevolutionary outcomes of interhemispheric dispersal

Dispersal events offer a unique window into macroevolutionary processes. While several hypotheses predict alternative outcomes from such events, many empirical studies have been limited in geographic and phylogenetic scale. Here, we tested some of these hypotheses by comparing an assemblage of 16 oscine passerine clades, representing independent dispersal events into the Western Hemisphere, to their sister clades in the Eastern Hemisphere. We also compared the diversity of this assemblage of clades to an older, incumbent passerine clade in the Western Hemisphere, the suboscines. We tested for ecological opportunity and incumbency-mediated constraints versus neutrality by integrating estimates of clade-specific morphological disparities with models of multivariate regimes of trait evolution. While there was no consistent outcome of oscine dispersal and macroevolution in the Western Hemisphere relative to their Eastern Hemisphere sister groups, most clades supported a role for ecological ..., , , DATA FOR:

DATA FILES:

1. IOCJetzNames\_AgeWork.csv
A csv file containing a list of species with their IOC checklist name, their name in the Jetz et al. 2012 phylogeny, and to what clade they belong to as part of this study. Species with values of \"NA\" in the 'Jetz Name' column are recognized on the IOC checklist but are not included in the Jetz et al. 2012 phylogeny.
2. JetzTree\_SequenceList.csv
A csv file containing a list of the species included in the Jetz et al. 2012 phylogeny, whether each species is represented by sequence data, and GenBank accession numbers for each sequence used for these species.
3. AppendixTable1.csv
A csv file containing the raw morphometric data measured from study skins used in this study, including the measurements from Imfeld and Barker 2022. Complete methods for data collection are included in the manuscript...
