While it has long been known that in small animals, such as insects, sufficient gas transport could be provided by diffusion, it is now recognized that animals generate and control convective flows to improve oxygen delivery across a range of body sizes and taxa However, size-based methodological limitations have constrained our understanding of the mechanisms that underlie the production of these convective flows Recently, new techniques have enabled the elucidation of the anatomical structures and physiological processes that contribute to creating and maintaining bulk flow in small animals In particular, synchrotron X-ray imaging provides unprecedented spatial and temporal resolution of internal functional morphology and is changing the way we understand gas exchange in insects This symposium highlights recent efforts towards understanding the relationship between form, function, and control in the insect respiratory system (C) 2010 Elsevier B V All rights reserved
