Meeting Abstract

48.2  Thursday, Jan. 5  A mechanism for metabolic scaling in insects CALLIER, V; Arizona State University

In insect larvae, the tracheal system grows in discrete steps, increasing in size only at each molt. In contrast, the body increases in mass continuously, and metabolic demand increases in concert. This mode of growth makes insects particularly well suited to study the effects of growth on the changing relationship of metabolic supply and demand.
