| compressible gas gills of diving insects: measurements and models. | many diving insects collect a bubble of air from the surface to supply their oxygen requirements while submerged. it has been theorised that these air bubbles may also act as compressible gas gills, as the low oxygen partial pressure p(o(2))within the bubble caused by the insect's respiration creates a gradient capable of driving the diffusion of oxygen from the water into the bubble. under these conditions nitrogen diffuses in the opposite direction, resulting in a situation where the volume of ... | 2010 | 19651133 |
