New Paper: Global patterns of alien species richness

We have a new paper out today Nature Ecology and Evolution, comparing hotspots of alien species richness around the globe (writeup here on BBC). We were happy to include our GABI/antmaps data as part of a broader effort to compare alien species richness patterns across taxonomic groups. Ants and reptiles turned out to be quite correlated for some reason, although it is not clear why.

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.

New Paper in J. of Biogeography

A new paper is out in Journal of Biogeography, led by Patricia Wepfer. The paper uses our GABI data as a basis to analyze patterns of beta diversity in East Asia. As expected, climate had a major effect on ant beta diversity. But we also found a surprising effect of historical land connections that explained ant diversity patterns better than modern connectivity.
