Leading entomologist to give talk at UCR on communication and cooperation in ant societies
Date:3/3/2010

RIVERSIDE, Calif. Bert Hlldobler, one of the world's great ant experts and Foundation Professor of Life Sciences at Arizona State University, will give the 2010 Alfred M. Boyce Lecture at the University of California, Riverside on Monday, March 8.

His lecture, titled "The Superorganism: Communication and Cooperation in Ant Societies," will take place at 4 p.m. in the Genomics Auditorium, Room 1102A, followed by a reception at 5 p.m. in the Entomology Department Courtyard. Both the talk and the reception are free of charge and open to the public.

Superorganisms are insect societies in which vast numbers of often tightly entangled and socially interdependent insects function as a single organism.

Ant societies, which are superorganisms, rely upon successful communication through chemical and mechanical signaling on both inter-individual and pan-society levels, as well as on a division of labor between hundreds of thousands of individual organisms.

The sophistication with which the ants combine different signal modalities into "syntax" has important implications for the evolution of social grouping and communication. Similar to human tribes in New Guinea, certain ant species engage in ritualized tournaments with other ant societies in order to collectively communicate size, strength and "resource holding potential."

Hlldobler explained that in tightly organized social groups, contests for limited resources are usually not between single individuals; instead groups of individuals compete as units. According to him, in such cases, differences in the number of individuals per group determine the contest's outcome.

Prior to becoming a faculty member at Arizona State University, Hlldobler served as the Alexander Agassiz Professor of Zoology at Harvard University and held the Chair of Behavioral Physiolog
