New paper on global macro-invasion dynamics

A new paper on global macro-invasion dynamics led by Hanno Seebens, Franz Essl, and the GLONAF group has just come out in PNAS.  We were happy to contribute our GABI data on alien ant emergence and spread over time. Main punch line is that emergence of new invaders comes from expansion of trade networks and environmental change into new source pools and this keeps the rate of new emergence high.  Check it out!

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?

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.
