ESA 2013 Annual Meeting – two posters on North American and Colombian weevils

Our group is giving a regular and a virtual poster on weevils at the 2013 Annual Meeting of the Entomological Society of America, held in Austin, TX. The corresponding PDFs are posted here (click on the titles). Andrew Jansen and Guanyang Zhang are also presenting on southwest U.S. and Cuban entimine weevils, respectively. An ESA 2013 meeting review will be forthcoming. The image shows Pachyrhinus californicus (Horn, 1976).

Prior work on concept taxonomy – 2013 onwards

February, 2015. The first fleshed-out use case of reasoning over taxonomic concepts with the Euler/X toolkit is now published.

Franz, N.M., M. Chen, S. Yu, P. Kianmajd, S. Bowers & B. Ludäscher. 2015. Reasoning over taxonomic change: exploring alignments for the Perelleschus use case. PLoS ONE 10(2): e0118247. doi:10.1371/journal.pone.0118247. Available on-line here.

An overview – initiated in early November, 2013 and regularly updated (throughout 2015) – of papers and presentations related to the taxonomic concept approach. Since the Fall/Winter of 2013 we have a working Python toolkit Euler/X (openly available on-line) that can read in two taxonomies (T1,T2), a set or articulations (A), and additional constraints (C). The toolkit then calls up Answer Set Programming reasoners to infer and visualize an alignment among the taxonomies that satisfies the constraints. A short video is posted here.

Weekly reading: Diversification patterns in the Mediterranean tenebrionid genus Blaps

Another weekly reading, an empirical paper focusing on a Mediterrranean tenebrionid beetle radiation – genus Blaps Fabricius – using the DEC model by Ree et al. Reference: Condamine, F.L., L. Laurent Soldati, A.-L. Clamens, J.-Y. Rasplus & G.J. Kergoat. 2013. Diversification patterns and processes of wingless endemic insects in the Mediterranean Basin: historical biogeography of the genus Blaps (Coleoptera: Tenebrionidae). Journal of Biogeography 40: 1899–1913.

This paper’s group leader Gael Kergoat participated in the Third International Tenebrionoidea Symposium held earlier this year at ASU.

TDWG 2013 in review

TDWG 2013 in Florence, Italy, has ended, and it was a great meeting at a gorgeous location. Shown on the photo (left to right): Hilmar Lapp of Phenoscape (NESCent), Mark Schildhauer of NCEAS, and Cynthia Parr of EOL. Our group presented 5 talks and chaired the “Formal Models” section of the Semantics for Biodiversity Symposium. Talks presented by Nico Franz are here; and some impressions from the Conference are posted here. There will be a guest edited Special Issue of the Semantic Web Journal with select papers given at the Symposium. Biodiversity informatics is a truly global discipline, and one of the interesting subcontexts of attending a TDWG meeting is to understand how different regions and initiatives around the world aim for creating a sustained, useful, modern informatics infrastructure for biodiversity data at both local and global scales.
