New paper published: Potentials of micro CT for ant taxonomy

In the paper we explore the potential of x-ray micro computed tomography (μCT) for the field of ant taxonomy and use it intensively for the descriptions of two remarkable new species of the genus Terataner from Madagascar. In addition to the traditional way of presenting new species with stacked montage light photography, we also provide 3D models based on μCT data and make the whole 3D datasets available online through Dryad.

One important aspect of the study is to assess how μCT can improve collections-based research of ants and other insects. Our μCT-based 3D models can be virtually rotated, sectioned, measured, and dissected, thus allowing a wide range of analyses of the anatomy and morphology of the studied organisms. By generating and presenting virtual 3D models of ants (or other animals) we support the establishment of virtual natural history collections that permit rapid and free access to anatomically correct and permanent digital reconstructions or avatars of physical specimens. Another great advantage is of the technology is the ability to print physical models of the scanned specimens, which can be used for a variety of research, museum, educational, and outreach purposes.

New ant species- in 3D!

We have two new papers out in PLoS ONE today describing some new species and highlighting the potential of micro-CT for ant taxonomy.

The first paper, headed by Eli and co-authored by Georg, revises one crazy spinescent Pheidole group from New Guinea, and notes interesting findings on the musculature under the spines.

We named these species Pheidole drogon and Pheidole viserion after the dragons from George R.R. Martin’s A Song of Ice and Fire series.

The second paper, led by Georg, revises the Pheidole knowlesi group from Fiji including complete micro-CT galleries of all castes of six species from the group. This knowlesi group is not as morphologically spectacular as cervicornis, but is of great interest to us as it pertains to our work on the taxon cycle hypothesis.

We hope these show a glimpse of what cool things can be done with micro-CT for organismal biology, biodiversity studies, and taxonomy.
