New paper on 3D ant systematics

We have a new paper out today in ZooKeys revising the doryline genus Zasphinctus in the Afrotropical region. Led by Paco Hita Garcia, we do a deep dive into using microCT and 3D data for ant taxonomy. In previous recent papers, we provided 3D models and virtual type specimens to support taxonomic work. Here we go further and exploit more fully the power of micro-CT to discover and examine characters useful for systematics and the 3D representation of virtual specimens.

The three species are named after three important figures in biodiversity conservation. We named one after former US President Barack Obama, for his role in protecting natural areas. The species was found within a few kilometers of Obama’s father’s village in Kenya. The second species was named after E.O. Wilson, discovered from Gorongosa National Park, Mozambique, where he and his foundation have done a lot of work over recent years. The third species is named after Nigerian environmental activist Ken Saro-Wiwa.

New paper on evolution of ant spinescence in Pheidole

A new paper from the lab was published today in the Biological Journal of the Linnean Society focusing on aberrant spinescent phenotypes in Pheidole (including the famous dragon ants). We look at spinescence from a number of angles including phylogenetic, ecological, geographic, and 3D morphology. This study sheds light on the complexity of the issue of spine phenotype evolution. There are a number of open questions and some big mysteries. For starters, why the heck has spinescence evolved so many times in the Indo-Pacific, but no spiny Pheidole in New World? Check out the paper here!

 

 

 

 

HoloLens comes to the Economo Unit

How would you like to be in the same room as an ant the size of a horse? In reality that’s a ridiculous idea, but in augmented reality anything is possible. This week, OIST’s Biodiversity and Biocomplexity Unit tested a new augmented reality device: the Microsoft HoloLens. Pavel Puchenkov of OIST’s Scientific Computing & Data Analysis Section designed a demonstration using a 3D-scanned model of the newly discovered ant species, Pheidole drogon. With the HoloLens, researchers were able to explore this species’ exceptionally spiny shape.

actually see the ant, but it all looks very dramatic

While the applications available for the HoloLens are currently limited, the opportunities quickly become apparent. The ability to display holographic renderings of specimens in 3D has the potential to turn any room into a stunning museum exhibit. It’s clear that this technology has the potential to create or enrich experiences that we can use to communicate life’s diversity and evolutionary history.
