Online publication to follow the three AVAToL projects

PLOS Currents: Tree of Life

PLOSPeer-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…)


Presentation slides from Evolution 2013 available

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.


Building an API for the Open Tree of Life database

Do you want an app for this?

Screen Shot 2012-08-29 at 9.22.20 PMThe 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.

“We need a sense of ownership of phylogenetic trees”

Where are the fungi datasets?

FungiA couple thousand fungi phylogeny studies have been published in the past twelve years. Clark University postdoc researcher Romina Gazis has gone through all of them. Now she is working on a bigger challenge: finding all the trees and datasets that were the foundation of those studies.

Ideally, all scientists who publish a phylogenetic tree would also deposit the datasets they used to create such trees at a publicly available online database. That allow other researchers to synthesize data from different sources to advance the knowledge about relationships between certain species and their evolutionary history.

Unfortunately, most of those datasets are not publicly available. Gazis only found datasets for about a quarter of the two-thousand fungi articles she surveyed. “Around 600 studies had tree files available, but not necessarily complete,” she concluded. “Some scientists deposited one but not all the trees.” (more…)


Tree of Life: Are big changes looming on the horizon?

All species like some gadgets

Photo by PublicDomainPictures (Creative Commons Deed CC0)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…)


Teamwork:

Across disciplinary boundaries

The interdisciplinary team of the Open Tree of Life project

What do a fungal evolutionary biologist and a computer scientist have in common?

It is usually easier to name a long list of differences, but that does not mean that those scholars are investigating different issues all the time. They may be very much interested in the same problems, yet apply different perspectives and methods in search for answers.

Those scientists could continuously work on their individual research projects for may years. However, in some cases only an interdisciplinary collaboration leads to a solution. The investigators of the Open Tree of Life project hope this will be the case for them as well. Their goal: creating a tree of life that includes all 1.9 million known species. (more…)


Quiz time!

Dear Colleagues,

Put on your quiz hats! We need some good questions!

As our team works to build an Open Tree of Life for professionals we are also working on a educational version of the tree for the everyone else, meaning educators, students, and the public in general.This public site will have a FUN QUIZ to test people’s knowledge of evolution, and we need questions for it!

SUBMIT YOUR QUESTIONS HERE

SAMPLE QUESTIONS:
Easy:
• Sponges fall within which major group on the tree of life? (animal, plant, bacteria)
• Which are mushrooms more closely related to: (animals, red algae or plants?)
• How many origins of life were there on Earth? (1, 2, 3)
Medium:
• Which organisms represent the greatest biomass on Earth?
(bacteria and archaea, mammals, fish)
• How many major groups of organisms are represented in a ham sandwich? (1, 2, 3)
• Genes (i.e. portions of genomes) yield the same estimate for the ToL? (Yes, No, Sometimes)
Expert:
• The top 10 infectious agents on earth appear where on the tree? (bacteria only, in both bacteria and eukaryotes, in both bacterial and archaea)
• Each gene sequenced and analyzed yields the very same answer for the ToL? (Yes, No, Sometimes)You can submit up to three questions with this form, but feel free to submit more by starting a new one!
