...-amended dog food (CADF) diet for 4 weeks. After this period, dietary shift resulted in a significantly higher average mass-specific standard metabolic rate (SMR) in CADF-fed females compared with DF-fed females. We also uncovered significant 13 C-enrichment in DF-fed insect samples relative to CADF-fed...

... of P crit determination: (1) measuring the most appropriate benchmark Ṁ O 2 state for P crit determination ( Ṁ O 2 ,std , the Ṁ O 2 required to support standard metabolic rate); (2) reducing water P O 2 ; and (3) calculating P crit from the Ṁ O 2 versus P O 2 curve. We make suggestions on best...

... Ltd 2018 Summary: This Commentary argues that the concept of the critical oxygen tension in water-breathers is fundamentally flawed for many reasons, and it presents the case for more useful alternatives. Critical oxygen tension Standard metabolic rate Routine metabolic rate Active...

.... In the present study, we investigated whether metabolism, behaviour, growth and the potential relationships among them vary with food availability in sterile triploid carp. In this experimental animal model, we investigated the standard metabolic rate (SMR), growth performance and personality traits (i.e...

... and biomineralization of hard-shell clams were more complex. Elevated P CO 2 (~800–1500 μatm) had no significant effects on standard metabolic rates (indicative of the basal energy demand), but affected growth and shell mechanical properties in juvenile clams. Moderate hypercapnia (~800 μatm P CO 2 ) increased shell...

... in ecophysiology and conservation physiology studies; however, few studies have tested whether they yield comparable results. We examined whether two fundamental measures, standard metabolic rate (SMR) and maximum metabolic rate (MMR), vary based on the method employed. Ten bridled monocle bream ( Scolopsis...

... by its relative high standard metabolic rate and optimal (i.e. least cost) swimming speed. To test the hypothesis that lateral line afferent information contributes to efficient locomotion in an active pelagic species, the swimming performance of S. lalandi was evaluated after unilateral disruption...

... weighed less than controls. Both experimental treatments also had sex-specific effects on standard metabolic rate (SMR). Females exposed to food restriction or CORT treatment during development had higher SMRs in adulthood than control females, but neither stressor affected SMR in males. There were...

...Tommy Norin; Hans Malte SUMMARY Standard metabolic rate (SMR) and active metabolic rate (AMR) are two fundamental physiological parameters providing the floor and ceiling in aerobic energy metabolism. The total amount of energy available within these two parameters confines constitutes the absolute...

.... In ectotherms it has been suggested that standard metabolic rate(MR) is related to Darwinian fitness, since it reflects energy usage and expenditure. The metabolic rate of the cricket Hophlosphyrum griseus was determined at three ambient temperatures. Repeatability of MR was estimated by product–moment...

... of the minimum speed for bonito hydrostatic equilibrium (1.2 FL s -1 ). The optimum swimming speed ( U opt ) for the bonito at 18±2°C is approximately 70 cm s -1 (1.4 FL s -1 ) and the gross cost of transport at U opt is 0.27 J N -1 m -1 . The mean standard metabolic rate (SMR), determined by extrapolating...

... that standard metabolic rates were higher in individuals having a stout body shape, and that net swimming cost was not related to body shape. Accordingly, the higher swimming cost of stout individuals is probably an indirect consequence of an increase in standard metabolic rate. In wild yellow perch, absolute...

The juvenile kawakawa had significantly higher standard metabolic rates than the chub mackerel, because the total rate of oxygen consumption at a given swimming...
