Die Regelung des Stoff- und Energieverbrauchs beim Wachstum der Wirbeltiere

The metabolic rate and heat loss of fat and thin men in heat balance in cold and warm water

“…The present studies of fat and thin men in a steady state of heat exchange in water were designed partly to confirm or refute this evidence that stimulation of deep temperature receptors plays a major part in adjusting the metabolic rates of fat and thin men to their different rates of heat loss during prolonged exposures to cold. They were also designed to show whether fat and thin men have different critical ambient temperatures, at which physical temperature regulation is complete and below which the metabolic rate is increased (Rubner, 1902;Burton & Bazett, 1936;Scholander, Hock, Walters, Johnson & Irving, 1950).It was hoped that these experiments would also show whether cold vasodilatation substantially reduced the tissue insulation of fat men in near-freezing water. This seemed probable, as cold vasodilatation takes place eventually in cold extremities of even generally chilled people (Keatinge, 1957) and appears to be due largely to the direct effect of low temperatures on blood vessels (Keatinge, 1958).…”

The carbon and nitrogen budget of Desmophyllum dianthus—a voracious cold-water coral thriving in an acidified Patagonian fjord

“…5C , 5D ). The 1.5-fold higher respiration rate within the first day after ingesting a large food ration (zooplankton plus krill, incubation ‘krill.d1’) as compared to one day later (incubation ‘krill.d2; corals not fed between the two incubations) likely reflects the ‘specific dynamic action of food’ (SDA, Rubner, 1902 ). The SDA describes the increased metabolic rate of animals after feeding, owing to the energetic expenses of food capture and digestion ( McCue, 2006 ; Secor, 2008 ).…”
