Dear all,

We are pleased to announce a Uberon workshop, satellite of the Biocuration2014 meeting, to be held in Toronto, Canada, on the 5th and 6th April 2014.

Uberon is an integrated cross-species anatomy ontology, representing a variety of entities classified according to traditional anatomical criteria such as structure, function, and developmental lineage. Uberon provides a necessary bridge between anatomical structures in different taxa for cross-species inference, allowing integration of model organism, human, and comparative morphology data.

This workshop will be user-oriented, and will be devoted to introducing and training participants to the use of Uberon. For more information and schedule, please see the workshop website:
http://edu.isb-sib.ch/course/view.php?id=167

Attendance is limited, and places will be allocated on a first come, first served basis. The estimated registration fee is C$200. The registration page is available at:
http://www.isb-sib.ch/edu/Registration/SIB_courses.php?id=234

For more information about the Biocuration conference, please see:

We’re happy to announce that a description of the Environment Ontology (ENVO; www.environmentontology.org) has been published in the Biomedical Ontologies series of the Journal of Biomedical Semantics:
http://dx.doi.org/10.1186/2041-1480-4-43

Capturing the environmental context of biological and biomedical entities is key to fully understanding their qualities, behaviour, and composition. That being said, concisely but meaningfully describing an “environment” with a small number of ontology classes quickly becomes a complex undertaking. This is further complicated by variability in the understanding of the boundaries and parts of environments as well as their relations to other entities of interest, even within a single discipline.

ENVO aims to offer an approachable and easily applicable ontology of environments, with classes that capture key elements of a given environmental context. In particular, ENVO focuses on the environmental system an entity is embedded in, the environmental features that causally influence it, and the environmental material that surrounds it. These complementary perspectives provide a compact but informative contextualisation that can readily aid, for example, data discovery and comparative studies. Work is underway to represent entities such as habitats, niches, and environmental conditions in order to further tease apart and define aspects of the environment. Further, instances of ENVO classes are being linked to classes in the Gazetteer (GAZ) to support (among other efforts) environmental contextualisation of place names.

To promote interoperability across existing ontologies, ENVO is being developed towards compliance with the OBO Foundry Principals. Linking ENVO with phenotypic ontologies and data offers great potential in enabling biological investigation using ontological resources and we look forward to exploring this at Phenotype RCN 2014!

The Phenotype day [International Conference on Intelligent Systems for Molecular Biology] is an initiative developed jointly with the Bio-Ontologies and BioLINK Special Interest Groups.

The systematic description of phenotype variation has gained increasing importance since the discovery of the causal relationship between a genotype placed in a certain environment and a phenotype. It plays not only a role when accessing and mining medical records but also for the analysis of model organism data, genome sequence analysis and translation of knowledge across species. Accurate phenotyping has the potential to be the bridge between studies that aim to advance the science of medicine (such as a better understanding of the genomic basis of diseases), and studies that aim to advance the practice of medicine (such as phase IV surveillance of approved drugs).

Various research activities that attempt to understand the underlying domain knowledge exist, but they are rather restrictively applied and not very well synchronized. In this Phenotype Day we propose to trigger a comprehensive and coherent approach to studying (and ultimately facilitating) the process of knowledge acquisition and support for Deep Phenotyping by bringing together researchers and practitioners that include but are not limited to the following fields:

• biology as well as computational biology

• genomics, clinical genetics, pharmacogenomics, healthcare

• text/data mining and knowledge discovery

• knowledge representation and ontology engineering

Our paper describing the Vertebrate Taxonomy Ontology (VTO)  is published!  See: http://www.jbiomedsem.com/content/4/1/34 .

One primary objective for Phenoscape and similar projects is to aggregate phenotypic data from multiple studies to named taxa, which in many phylogenetic studies are species but also might be at higher taxonomic levels such as genera or families. While there are many widely used taxonomies that include rich sampling of species and higher taxa, for example Bill Eschmeyer’s widely used Catalog of Fishes, there are few vetted “bridging” taxonomies that allow for aggregating data across, say, fishes, amphibians, and mammals. This problem becomes even more acute when you consider integrating data for extinct taxa as well. As a first step towards addressing this issue for vertebrates, we created the Vertebrate Taxonomy Ontology (VTO) that brings together taxonomies from NCBI, AmphibiaWeb, the Catalog of Fishes (via the previously existing Teleost Taxonomy Ontology), and the Paleobiology Database. The resulting curated taxonomy contains more than 106,000 terms, more than 104,000 additional synonyms, and extensive cross-referencing to these existing taxonomies. The Phenoscape Knowledgebase will leverage this taxonomic ontology by allowing for phenotype statistics to be displayed by taxon, including coarse measures of the extent of annotation coverage and phenotypic variation. Though phenotypes may be annotated to a species, the use of an ontological framework for the taxonomic hierarchy facilitates aggregating phenotypes to higher levels, such as genera or families. In the future, we hope to be able to integrate other excellent and rich sources of taxon-specific taxonomies, such as that in the Reptile Database or the International Ornithologists’ Union Bird List. This is a work-in-progress and the Phenoscape team is certainly interested to integrate new taxonomic sources as well as explore different ways that such a resource can be used and developed by the larger community.

Last week, the Phenotype RCN hosted a cross-working group call featuring presentations by Ramona Walls on the Plant Ontology and Cross-Species Reasoning [pdf] and Laurel Cooper on Common Reference Ontologies for Plants.

Dr. Walls (The iPlant Collaborative, University of Arizona, and New York Botanical Garden) demonstrated how the PO defines anatomical terms in a way that they can be used across all green plant species. After an overview of the ontology, which can be searched and browsed at http://plantontology.org/, she discussed its evolution, main branches (“plant anatomical entity” and “plant structure developmental stage”), and characteristics shared with CARO (the Common Anatomy Reference Ontology). She talked about specific changes to the ontology that make it work better for all green plants and presented use cases concerning comparison of gene expression, traits, and phenotypes across species.

Dr. Cooper (Oregon State University) followed with a talk about the PO and cROP, the Common Reference Ontologies for Plants. She identified problems arising from free-text phenotype descriptions and scattered data resources, and demonstrated how the PO fits into the centralized cROP platform, where reference ontologies for plants will be used to access data sources for plant traits, phenotypes, diseases, genomes linked to gene expression and genetic diversity data across a wide range of plant species. The cROP Ontology Database may be accessed via its web portal, http://crop.cgrb.oregonstate.edu/.

Many thanks to Ramona and Laurel for their outstanding talks!

The Phenotype RCN plans to host monthly calls the first Monday of every month at 8 a.m. Pacific / 11 a.m. Eastern time. If you would like to receive invitations to join via WebEx, please email Erik Segerdell. Suggestions for topics and volunteers for presenters are welcome!

bat fly (Diptera: Nycteribiidae)

A bat fly (Diptera: Nycteribiidae) poses for the camera. It’s barely recognizable as a relative of the familiar Drosophila melanogaster (Diptera: Drosophilidae) and is radically different from the fish tongue-eating arthropod in the photo below. This photo by Gilles San Martin (CC BY-SA 2.0).

The Phenotype RCN Arthropod working group has focused mostly on the development and characterization of the Common Arthropod Anatomy Ontology (CAAO). Despite difficulties defining basic classes due to the immense differences in basic anatomical concepts—there are, after all, more than a million known species of arthropods, with almost as many different forms (see photos above and below)—we made progress in the development of certain portions of CAAO. During 2013 the group established the basis of classes and relationships referring anatomical structures of the arthropod the integument. Establishing this system is especially crucial for disciplines targeting world species diversity, such as arthropod taxonomy and phylogenetics, where more than 90% of the applied characters are related to the outer layer of the integument, the cuticle. Efforts have also been made on the development of the arthropod nervous system portion by the adoption of the relatively recently published relation system by Richter et al. (2010).
The development of CAAO is ongoing, but the focus of the working group has shifted a bit towards the establishment of outreach strategies for the better utilization of available ontologies by the domain experts and to establish tighter collaborations between research group members. We’re especially interested in seeding research that will become the basis new funding. The main subjects of this new directions are:

  1. Cooperation between working group members who develop tools that enhance ontology development and usage for domain expert communities [e.g., mx (Yoder 2014) and Morph·D·Base (Vogt and Grobe 2010)].
  2. Making more widely accessible and understandable the ideas developed by individual working group members on applications of ontologies to different areas of arthropod research [e.g. ontology based measure of structural complexity for phylogenies (Ramirez 2013); demarcating and differentiating basic categories of anatomical entities (Vogt 2010) and application of semantic models in species descriptions (Balhoff et al. 2013)].
  3. To define the role and place of homology concepts in arthropod ontologies [e.g. Szucsich and Wirkner 2007, Franz 2013].

During 2013 some members of the Arthropod-working group were able to meet during two Arthropod specific meetings organized in Germany: Willi Hennig Society meeting in Rostock August 3rd-7th and the 6th Dresden Meeting on Insect Phylogeny in Dresden September 27-29. Although it was possible at these meetings to start cooperation on the above mentioned areas and outline future directions of the working group, it was also accepted that further meetings with more participants of the working group is needed in terms of establishing the planned collaborations. The annual RCN summit meeting on 21-23 February 2014 will be attended by most of the key personnels and hopefully help the working group to assure a workflow to reach the new directions.

In an effort to expand the user community and to demonstrate what is possible using our infrastructure, members of the Phenoscape team gave multiple presentations across two continents on our recent developments. In late October Paula Mabee gave an invited presentation on mapping phenotypes across phylogenies at the Muséum national d’Histoire naturelle in Paris. This was followed by presentations at the 73rd annual meeting of the Society of Vertebrate Paleontology (SVP) in Los Angeles and the 2013 meeting of the Taxonomic Database Working Group (TDWG) in Florence, Italy. Phenoscape had a significant presence at SVP with both a poster presented by Alex Dececchi demonstrating our progress in generating supermatrices from our annotations as well as a talk given by collaborator Karen Sears, using EQ supermatrices from Phenoscape fin/limb data to examine integration patterns across the fin to limb transition. Karen’s talk marks the first of the collaborations coming out of our 2013 San Francisco workshop. It also showed how data from Phenoscape can drive independent projects and is easily integrated with existing phylogenetic and statistical tool such as Mesquite and various R modules. The talks and poster were well received, with numerous researchers inquiring on how they could incorporate Phenoscape or use ontology based annotations.
