Symposium 12: Ant phylogenetics: New molecular trees to address old problems in ant biology
This symposium presents the results of a new wave of molecular phylogenetic studies addressing issues in ant evolution and biology. Ants have long received much attention from a wide variety of biological disciplines, but our poor understanding of their phylogenetic history hinders a full evolutionary interpretation of this biological information. This situation is rapidly changing, as many researchers are adding to phylogenetic knowledge using new molecular data and analytical techniques. The studies presented in this symposium range from broad-scale treatments of major ant lineages, down to species-level phylogenies. These new phylogenies also shed new light on many prominent themes in social insect biology, including coevolution, biogeography, social parasitism, speciation, foraging strategies, colony structure, and behavioral evolution.
