... for an increase in T b ( Richards, 1970a ; White, 2006 ). Eventually, as T b does increase, the thermal tachypnea gives way to thermal hyperventilation with a deep and slow breathing pattern ( Richards, 1970a ; White, 2006 ). In embryos, even when close to hatching like those of the present study, active...

..., breathing patterns, metabolic rates, lung volume and lung diffusing capacity were measured at rest and during exercise in the pregnant skink Tiliqua nigrolutea . Breathing patterns were largely unaffected by gestation; however, decreases in metabolic rate (rate of oxygen consumption) in the late stages...

... , which is responsible for the emergence of DGCs during inactivity. To test this, Nauphoeta cinerea cockroaches had their brains inactivated by applying a Peltier-chilled cold probe to the head. Once brain temperature fell to 8°C, cockroaches switched from a continuous to a discontinuous breathing pattern...

...Suzanne L. Munns SUMMARY High gestational loads result in fetuses that occupy a large proportion of the body cavity and may compress maternal organs. Compression of the lungs results in alterations in breathing patterns during gestation, which may affect the energetic cost of breathing...
