This dataset and associated phylogeny describes brain weights, body weights, dietary categories, social systems, mating systems, and group sizes for 143 primate species. These data were originally compiled in DeCasien et al. (2017). The phylogeny is a 50% majority rule consensus tree from the 10k Trees website.
Format
A list containing a dataset and an associated phylogeny. The phylogeny is a pruned consensus tree for 143 species of primate (excluding humans). The dataset is a data frame with 143 observations and 11 variables:
- species
The primate species
- clade
The clade of the primate species
- brain_weight
Average brain weight, in grams
- body_weight
Average body weight, in grams
- diet
A factor with four levels indicating whether the species' dietary category is folivore, frugivore, frugivore/folivore, or omnivore
- percent_fruit
Percentage of fruit in diet
- social_system
A factor with four levels indicating whether the species' social system is solitary, pair-living, harem polygyny, or polygynandry
- mating_system
A factor with five levels indicating whether the species' mating system is spatial polygyny, monogamy, polyandry, harem polygyny, or polygynandry
- group_size
Average group size
