Ecology and behavior of social insects

Organizers: Norio Yamamura (Kyoto University), Nan-Yao Su (Universality of Florida).
Date: 10:00-13:00, September 17, 2006
Place: Room B
Introduction:
Theoretical problems on ecology and evolution of social insects have extensively been studied specially on Hymenoptera. However, mathematical methods for analyzing termite behavior and spatial dynamics have recently been developed. In this symposium, we will discuss such methods and compare them with theories of spatial dynamics of ants.
