The Arthropod Working Group of the Phenotype RCN stayed an extra day at Biosphere 2, after the annual group summit meeting, so that we could take stock of our own progress and discuss future interactions. We’re a heterogeneous crowd, each working on a different taxon (non-Hexapod Pancrustacea, Araneae, Hymenoptera, Coleoptera), often on different systems (integument, circulatory, neuroanatomy, etc.), and with different motivations (taxonomy, gene expression, evolutionary questions. etc.). Our annual meeting is a chance to catch each other up on progress in our systems but also to discuss limitations and possible solutions. We’re also charged with developing a common anatomy ontology that bridges disparate lineages, some of which are represented in existing anatomy ontologies (e.g., see Costa et al. 2013 and Yoder et al. 2010). In attendance this year: (L to R in photo below): Lars Vogt (Universität Bonn, Germany), Peter Grobe (Stiftung Zoologisches Forschungsmuseum Alexander Koenig Bonn, Germany), István Mikó (Penn State, USA), Stefan Richter (Rostock University, Germany), Martín Ramírez (Museo Argentino de Ciencias Naturales), Matt Yoder (Speciesfile, University of Illinois, USA), and, behind the camera, Andy Deans (Penn State, USA).

Wisely, we mostly steered clear of anatomical discussions—what’s this part here, and how do we define it?—which freed us up to talk about tools, progress, future proposals, and other news. That is, we had fewer tangents (and shouting) and more constructive conversations about collaboration. We captured most of the dialog in a Google doc (needs synthesis, for sure, and likely doesn’t capture ALL of our discussions, especially complex ideas articulated on the easel), but here are a few quick hits:
- The MorphDBase project (Grobe & Vogt) recently received funding for further development, and there is now a lot of potential to integrate ontologies. We discussed ideas for annotations, workflows, and how our projects could interact more with this resource.
- We talked about anatomical complexity more generally, especially in the context of essentialistic classes vs. those classes that are not so easy to define (cluster class). Our aim should be to develop user-friendly tools that make it easier to employ ontologies (i.e., that don’t require morphologists and taxonomists to overthink annotations or burden them with excessive evidence gathering).
- The spider ontology (SPD) is being used in an ongoing effort to extract characters from the literature (Ramírez). The group discussed tools that could help facilitate this process (e.g., CharaParser) and continued development of the SPD (especially Web-based tools, like mx, that facilitate rapid, community development of ontologies).
- The TaxonWorks project (Yoder) is looking for feedback regarding ontology tools. Should they integrate an ontology builder, à la mx? Perhaps one that interacts easily with Protégé (and the reasoners therein)? What about templates for certain kinds of taxonomic and phylogenetic characters? The user would plug in the anatomy and the phenotype, and TaxonWorks would write the semantics.
- Of course there was also some groupthink about how to make progress towards our mandate: to build a common anatomy ontology for arthropods. More on that later, but the consensus is that we should develop system-based pieces of it separately, forging links between them later. This ontology cloud would be synthesized in a future manuscript.
It was an intense, 12-hour, pizza-fueled, beverage-driven marathon in an inspiring location. After what we universally felt was forward progress, though, we’re excited for the next round! Perhaps in Argentina, Martín …?
As a side note, it was a bit cool in Arizona in February, for most arthropods anyway, but I did see two very cool critters: a Scolopendra centipede, which was way to fast for me to photograph, and a Hadrurus scorpion, which I forgot entirely to photograph. So here’s a great image from Flickr that illustrates them both:
