... emersion. Tidal crabs exhibited an endogenous rhythm of oxygen consumption during continuous submersion with lower oxygen consumption during periods of anticipated emersion, which was not detected in non-tidal crabs. During emersion, tidal crabs were able to buffer apparent changes in acid–base balance...

.... Therefore, we hypothesized that the medullary raphe modulates heat gain and loss thermoeffectors in birds. We investigated the effect of glutamatergic and GABAergic inhibition in this specific region on body temperature ( T b ), oxygen consumption (thermogenesis), ventilation (O 2 supply in cold, thermal...

... assessed dehydration stress tolerance in diapausing and developing Austrofundulus limnaeus embryos. We measured oxygen consumption rates under aquatic and aerial conditions to test the hypothesis that there is a trade-off between water retention and oxygen permeability. Diapausing embryos survive...

...Jessica E. Reemeyer; Bernard B. Rees ABSTRACT The critical oxygen tension ( P crit ) for fishes is the oxygen level below which the rate of oxygen consumption ( Ṁ O 2 ) becomes dependent upon ambient oxygen partial pressure ( P O 2 ). We compare multiple curve-fitting approaches to estimate P crit...

.... The lachrymal salt gland facilitates excretion of excess sodium (Na + ) and chloride (Cl − ) ions through active transport mechanisms. We investigated body fluid dynamics, oxygen consumption ( V̇ O 2 ) and osmotic status of terrapins exposed to an acute increase in salinity (12 to 35 psu) at 10 and 25°C to gain...

The tracheal system is a network of branching tubes that run from small openings (spiracles) on the outside of the insect's body through...

... high-temperature events. Therefore, we measured the metabolic response (mass-specific rate of oxygen consumption, Ṁ O 2 ) to thermal ramping (21–29°C) and the upper thermal tolerance limit ( U TL ) of two intertidal triplefin fishes ( Bellapiscis medius and Forsterygion lapillum ) under hyperoxia...

... hibernate with T b of 28°C. During the active season, oxygen consumption may vary 25-fold with little or no change in T b . During the austral winter, tenrecs are consistently torpid but the depth of torpor may vary. A righting assay revealed that T b contributes to but does not dictate activity status...
