... exchange ratio Cutaneous Gas exchange Calorimetry Cold Amphibian Indirect calorimetry, commonly referred to as respirometry, is a technique used to measure the oxygen uptake ( V̇ O 2 ) and/or carbon dioxide emission ( V̇ CO 2 ) of animals and is used as a common proxy for energy...

...M. D. Regan; J. M. Gosline; J. G. Richards SUMMARY Calorimetry is the measurement of the heat liberated during energy transformations in chemical reactions. When applied to living organisms, it measures the heat released due to the energy transformations associated with metabolism under both...

...Glenn E. Walsberg; Ty C.M. Hoffman SUMMARY Knowledge of animal energetics is based largely upon indirect calorimetry,which is estimation of metabolic heat production by an organism from measurement of indices such as oxygen consumption or carbon dioxide production. Remarkably, indirect calorimetry...

... of examining more closely the energy profile and metabolism of turtle cortical slices. Calorimetry is used to measure heat dissipation during normoxia and nitrogen perfusion (120 min) and the results are converted into an ATP utilization rate. These indicate that the control rate of ATP utilization (1.72 μ mol...

...Francisco Hontoria; John H. Crowe; Lois M. Crowe; Francisco Amat ABSTRACT The metabolic status of encysted Artemia embryos under anoxic conditions has been studied by calorimetry. Previous work demonstrated a very low, but still measurable, source of metabolic heat (31nWmg-1 drymass) after 6 days...
