faith_tree: Example data for Faith's phylogenetic diversity
In abdiv: Alpha and Beta Diversity Measures

This example was used to illustrate phylogenetic diversity in Faith and Richards (2012).

1	faith_tree

faith_tree is a phylogenetic tree with five tips, labeled a-e. It was created with the ape library.

In the paper, they give the total branch length as 41, but they don't assign a length to the branch leading to species "b" and "c". Looking at the figure, we estimated that the length should be 4. For that reason, the total branch length of faith_tree is 45, rather than 41.
