What does it mean to “have” the tree of life?
complete & dynamic
browse, download, query
use for research questions
implies digital access

Open Tree of Life
Taxonomy + Source trees
•filter / weight input trees• combine into synthetic tree
• feedback • input new data sets

~ 4% of all published phylogenetic trees
Stoltzfus et al 2012
Inputs: Phylogenetic data
Archiving sequence data is a community norm
![Page 6: Cranston Evolution 2013](https://reader033.vdocuments.net/reader033/viewer/2022060108/554e850db4c90526358b45d1/html5/thumbnails/6.jpg)
Heroic data collection effortsSurveyed >7000 phylogenetic studies in plants, fungi and animals, unicellular organisms
Result: data for >2300 studies, >4800 trees
Poster P133003 tonight!

Inputs: Taxonomies
Large fraction of species not represented in phylogenies
taxonomy provides backbone & coverage at tips
2,644,685 names: NCBI (structure) + GBIF (completeness)

Synthesizing trees and taxonomies
Graph database for phylogenies (treemachine) and taxonomy (taxomachine)
Allows for extremely efficient storage and retrieval
Rules to extract binary tree from highly conflicting graph
More details? Stephen Smith 8:30 am Monday!
