Spiracle activity in moth pupae--the role of oxygen and carbon dioxide revisited.
After decades of intensive research, the actual mechanism behind discontinuous gas exchange in insects has not been fully understood. One open question concerns the actual way (closed, flutter, andExpand

Issues of convection in insect respiration: Insights from synchrotron X-ray imaging and beyond
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 flowsExpand

Pump out the volume--The effect of tracheal and subelytral pressure pulses on convective gas exchange in a dung beetle, Circellium bacchus (Fabricus).
Many flightless beetles like the large apterous dung beetle Circellium bacchus, possess a subelytral cavity (SEC) providing an extra air space below the elytra which connects to the tracheal systemExpand

Hyperthermic Overdrive: Oxygen Delivery does Not Limit Thermal Tolerance in Drosophila melanogaster
Abstract The causes of thermal tolerance limits in animals are controversial. In many aquatic species, it is thought that the inability to deliver sufficient oxygen at high temperatures is moreExpand

Spiracular control in moth pupae
In conditions of low metabolic activity moth pupae of Attacus atlas show a triphasic, rhythmic pattern of CO2 release (discontinuous gas exchange, DGC). The phases, closed, fluttering and openExpand
