... rate(Δ L , Fig. 3I ). Besides the employment of convective strategies for breathing, oscillatory gas release in diffusion based respiratory systems may also result from changes in spiracle opening area, similar to the mechanism causing the discontinuous gas exchange cycle in a resting insect...

... during simultaneous measurements of CO 2 emission from the anterior mesothoracic spiracles and posterior body, which included the subelytral spiracles. However, when we sampled air directly from inside the subelytral cavity, we discovered that this pattern was reversed. A discontinuous gas exchange cycle...

..., which included the subelytral cavity, of a large apterous beetle, Circellium bacchus . Flow-through respirometry revealed a marked discontinuous gas-exchange cycle(DGC) pattern from the anterior half of the body. Very little CO 2 was released from the posterior body, where the DGC was not apparent...
