Symposium 2: Body size and natural history
Body size is one of the most important attributes for the life history of a species, influencing virtually all aspects of a species’ existence, including physiology, ecology, and reproduction. For example, among ants there are many associations between body size and life history, particularly with respect to the mode of founding new colonies. An increasing number of studies also report different sized queens within a nest that have different methods of nest founding. Lastly, several studies examine latitudinal patterns of body size, both at the individual and colony level. Overall, the literature on life history of social insects is underwhelming; even so only a fraction of this literature is linked to body size. This symposium will focus on two promising areas of research on body size: (1) body size and life history, and (2) local and latitudinal patterns of body size (both individual size or colony size). The underlying theme will be the link between the environment (at local or latitudinal scales) and body size and life history.
