We have just started a new project on the state and federally listed (G2G3, S2) Comanche Harvester Ant, Pogonomyrmex comanche. Harvester ants are known to be ecologically important seed consumers in dry to arid ecosystems worldwide, but also important movers of soil as they build deep large subterranean nests. Very little is known about this species, especially the factors that might be responsible for its population decline. We are currently using molecular markers to understand more about its mating biology and landscape ecology to model habitat suitability of this species. This work is supported by the Texas Army National Guard.
