Description
This is a comparative dataset on the evolution of shorebird egg size taken from Lislevand and Thomas (2006).
Usage
data(shorebird)
Format
The datafile contains a phylogeny (shorebird.tree) of 71 shorebird species as a 'phylo' object from the ape library. The tip names are the binomial names of the species. The file also contains a data frame (shorebird.data) of 71 complete cases for those species. The data frame contains six variables:
- Species
The species binomial name.
- M.Mass
The adult male mass body mass in grams.
- F.Mass
The adult female mass body mass in grams.
- Egg.Mass
The fresh egg mass in grams.
- Cl.size
