Professional Overview and ObjectivesI study distributional patterns of species-level radiations in their phylogenetic context in order to deduce factors that influence diversification. In the past 5 years I have maintained two parallel research foci: 1, analyzing a radiation of some 130 species of aggregate Holarctic distribution, classified in the genus Agonum (Liebherr & Schmidt 2004). Agonum beetles occupy wetland habitats in the northern hemisphere, and based on my analysis, we have learned that species that are successful in agricultural habitats are drawn from a close set of phylogenetic relatives, all of whom can live on disturbed, alkaline soil. This was the first world-wide phylogenetic analysis including all known species for a group of this magnitude (>100 species).Secondly I am studying native Hawaiian carabids in the genera Blackburnia (132 spp.) and Mecyclothorax (192 spp.). I have recorded date-locality data for over 42,000 specimens of Hawaiian Carabidae held in institutional collections and collected from 1832 until today. These data have been used to determine suites of species absent from recent sampling. These species’ associated absence suggests their extinction, or at least serious endangerment. I have in press my first paper describing new species in the Mecyclothorax radiation, with that manuscript comprising a first attempt at rapid publication of species descriptions using photo-micrography and database-driven distributional mapping. I have built my research group around graduate and undergraduate students. As at most 30% of insect diversity has been characterized (arguably only 20% to 10%), morphological systematists will be vital to worldwide biodiversity efforts that will occupy systematic entomology for the foreseeable future. Cornell is the major North American producer of highly trained and intellectually gifted Ph.D. insect systematists, and holds a major worldwide responsibility for continuation of this important entomological subdiscipline.
