awild | February 16, 2010The online early section of Molecular Phylogenetics and Evolution this week has the first comprehensive phylogeny of a rather important genus of ants: Myrmica.
Myrmica is ubiquitous in the colder climates of North America and Eurasia, with a few seemingly incongruous species inhabiting the mountains of tropical southeast Asia. The genus contains about 200 species, many that are common soil-nesting ants in lawns and gardens, and at least one damaging invasive species, M. rubra.
