Tempo and mode of evolution across multiple traits in an adaptive radiation of birds (Vangidae)

An ongoing challenge in macroevolutionary research is identifying common drivers of diversification amid the complex interplay of many potentially relevant traits, ecological contexts, and intrinsic characteristics of clades. In this study, we used geometric morphometric and phylogenetic comparative methods to evaluate the tempo and mode of morphological evolution in an adaptive radiation of Malagasy birds, the vangas, and their mainland relatives (Aves: Vangidae). To characterize the morphological diversity of the clade we used both landmarks and semilandmark curves from the bill and neurocranium, and linear measurements of pedal bones, all collected from microCT scans of museum specimens. The Malagasy radiation is more diverse in both skull and foot shape. However, rather than following the classic \"early burst\" of diversification, trait evolution accelerated well after their arrival in Madagascar, likely driven by the evolution of new modes of foraging and especially of a few species..., , # Tempo and mode of evolution across multiple traits in an adaptive radiation of birds (Vangidae)

### Data files

### RAW DATA FOR MORPHOMETRIC ANALYSES IN R

raw_coordinates.csv - a csv file containing the raw (compiled) landmark data for the cranium and upper bill

* Column 1 is the unique specimen identifier (e.g. Artamella_viridis_100859) 
* The other 408 columns are the x,y,z coordinates for each of the 136 landmarks in the cranium and upper bill. These are ordered the same as in landmark_names.csv

raw_coordinates_lower.csv - a csv file containing the raw (compiled) landmark data for the cranium and upper bill

* Column 1 is the unique specimen identifier (e.g. Artamella_viridis_100859)
