This data set contains four species-level comparative datasets used in Isaac et al (2005)
The datafile contains species level phylogenies and accompanying data frames of nine variables for each of four mammalian orders (Primates, Carnivora, Chiroptera and Marsupialia). The data were published in supplementary material for Isaac et al. (2005) as CAIC format files and text data files and have been converted for use in 'caper'. The data files are incomplete, with some variables having little or no data for some orders.
The variables (all saved as natural log values) are:
Species richness at the tips - all are set to 1 for use in
The average body mass in grams
Age at sexual maturity in months
Gestation length in days
Interbirth interval in months
The average number of offspring in a litter
Number of individuals in a typical group
Male mass /female mass
Male length / female length
