PLOS Currents: Tree of Life
Peer-reviewed articles about the Open Tree of Life as well as two related projects, Arbor and Phenomics, will be available on PLOS Currents: Tree of Life. The online publication allows the researchers to document their progress in developing software and other tools.
The three research endeavors were developed during an Ideas Lab last year as part of the National Science Foundation’s (NSF) Assembling, Visualizing, and Analyzing the Tree of Life (AVAToL) program. The Open Tree of Life project strives to produce the first draft of a comprehensive tree of life and provides tools for community enhancement and annotation. The Arbor project is developing comparative methods with utility across large sections and the entire tree of life. Finally, the Phenomics project is developing approaches for exploring and documenting phenotypic diversity across the tree of life.
“It’s meant to be a quick outlet for solid phylogenetic studies”
PLOS Currents websites encourage researchers to share their findings with a minimal delay to their peers. The Tree of Life section is focused on rapid publication of phylogenetic and systematic studies with novel data and/or analyses. According to Keith Crandall, one of the three editors of the journal and an investigator of the Open Tree of Life, “it’s meant to be a quick outlet for solid phylogenetic studies to get them and their data into the public domain.” (more…)
Open Tree of Life at meetings
The Open Tree of Life project is one of the many phylogeny projects that are featured during the Evolution 2013 meeting that currently takes place in Snowbird (UT). The presentation slides from Karen Cranston, the principal investigator of Open Tree of Life, are available online (LINK). Presentation slides from other investigators are added here in the upcoming days.
Evolution 2013 is the joint annual meeting of the Society for the Study of Evolution (SSE), the Society of Systematic Biologists (SSB), and the American Society of Naturalists (ASN). The conference meets jointly with the iEvoBio conference. Open Tree of Life is represented at both events. About 1400 participants are expected to share their research in evolution, systematics, biodiversity, software, and mathematics.
Biology + Technology = OTOL
One of the developers of the Open Tree of Life demonstrates Thursday, during a free webinar, how graph databases are used to construct a tree of life. The lecture is organized by Neo Technology, which is the maker of Neo4j, an open-source database that is used for OTOL.
Stephen Smith, an ecology and evolutionary biology professor at the University of Michigan, is going to explain how Neo4j and other digital technologies are assisting in constructing the tree of life. Starting at 10:00 PDT (19:00 CEST), he will also discuss other aspects of the interface of biology with next generation technologies.
“Our project is building the tools with which scientists in the community can continually improve the tree of life as we gather new information. Neo4j allows us to not only store trees in their native graph form, but also allows us to map trees to the same structure, the graph. So in fact, we are facilitating the construction of the graph of life,” says Smith.
Neo4j approached the Open Tree of Life team to present a webinar because it is a project that utilizes the Neo4j graph database to represent the interconnectedness of biological data. The company considers the project a great example of how a graph database can better model the natural world.
The online lecture is intended for a broad audience including beginner computer programmers, advanced hackers, data scientists, natural scientists, and anyone interested in the cross-section of science and technology, especially data modeling. Over 150 people have already registered online.

Do you want an app for this?
The developers of the Open Tree of Life would like to know from the phylogenetic community what kind of information they want to extract from its database when the first draft is released later this year. With those preferences, it is possible to develop an API that gives scientists the opportunity to build their own websites or software packages that use the data.
An API (application programming interface) is a digital tool that allows one website or software program to “talk” to another website to dig up certain pieces of data. For instance, a lot of people use Tweetdeck to navigate the ongoing bombardment of messages in the Twittersphere. In that case, Tweetdeck is connecting to Twitter, through its API, to receive and order the messages according to the preferences of the user.
In case of the Open Tree of Life, an API gives researchers advanced access to the data of about two million species, the phylogenies that have been created to illustrate possible relationships between them, and the underlying data and methods of synthesis. “For example, it will be possible to select smaller trees for specific species or find out how many studies there are for a particular node within the database,” says Karen Cranston, the lead investigator of the project.

All species like some gadgets
While movie hero James Bond gets his spy gadgets from his loyal developer Q, almost every other species on Earth has to put a little more effort in armoring themselves. But that does not mean they cannot rely on some good ol’ friends to do so. In fact, the acquisition of genes from two or more species through lateral gene transfer can lead to innovations that at times can be painful—sometimes even deadly—to others.
One of those evolutionary novelties is noticeable for certain types of jellyfish that developed the ability to sting after their ancestors acquired a gene from a bacterium and incorporated that material in their own DNA. This gene transmission helped jellyfish to create an innovative defense tool to fend off other species that could endanger them. The result is quite frightening: more humans get killed by jellyfish than sharks. (more…)
