Dynamics of Self -Organization of Ramified Patterns in an Electromechanical System
… in collaboration with researchers at the Santa Fe Institute, we theoretically explore a biological system: ant foraging colonies. These are commonly known to forage along ramified trunk trail networks. We show that the structure of these foraging patterns has consequences on the net energy …

Distribution and Management of the Red Imported Fire Ant, Solenopsis invicta Buren, in Virginia
Red imported fire ant specimens were first collected in Virginia in 1989 from colonies located in Hampton, Va. Now colonies are established throughout the Hampton Roads area of Virginia. Because the fire ant is a new pest information regarding the distribution, biology, and management of the ant in …

Foraging Activity and Food Preferences of the Odorous House Ant (Tapinoma sessile Say) (Hymenoptera: Formicidae)
Foraging activity and food preferences of odorous house ants (Tapinoma sessile (SAY)) were investigated in both the field and laboratory. Foraging activity was examined in the field from April to September 2001 by attracting T. sessile to feeding stations containing a 20% sucrose solution. Ant …

Fluctuations and response in complex biological systems: Watching stochastic evolutionary and ecological pattern dynamics
… dynamics in live cells, and bistability in ant foraging. In collaboration with experimentalists at MIT and UIUC, I have shown how noise can stabilize emergent behaviors such as Turing patterns in biofilms. Normally, one would think that noise destroys patterns but we found that fluctuations …

Sociobiology of the hypogaeic army ant Dorylus (Dichthadia) laevigatus Fr. Smith
… for their spectacular epigaeic raids, army ants have captured scientific attention for almost two centuries. They now belong to one of the best studied group of ants. However, most of our knowledge about army ants was derived from the study of the minority of specialized, epigaeicly active …
