      Areas of interest include ecology of desert ants, seed-harvester
ants, nest founding strategies, faunistics, ants the southwestern U.S and northwestern Mexico (and Baja California), hybridization and caste determination. Yes I would be willing to trade material at times.
     Well as you can guess I'm working on too many projects that include - social and genetic structure of Pogonomyrmex pima (with intermorph queens), nest founding in Pogonomyrmex huachuacanus (apterous queens), hybridization and caste determination in Pogonomyrmex rugosus and P. barbatus, Pleometrotic nest founding in Pogonomyrmex californicus, Incipient speciation in Pogonomyrmex
californicus, Latituinal gradients in colony size in seed-harvester ants.
