“…Protein restriction can create disproportionate rates of growth in different organs (Desai et al 1996), thus leading to differences in relative organ size, even at adulthood despite full compensation in terms of overall body size. In turn, this could create the observed variation in metabolism, since variation in the relative size of the most metabolically active organs (such as the liver and digestive tract) has been shown to be responsible for some of the inter-individual variation in RMR (Piersma et al 1996;Speakman & McQueenie 1996;Selman et al 2001), although these patterns do not always hold (Burness et al 1998).…”

Early nutrition and phenotypic development: ‘catch-up’ growth leads to elevated metabolic rate in adulthood

Resting metabolic rate (RMR) is responsible for up to 50% of total energy expenditure, and so should be under strong selection pressure, yet it shows extensive intraspecific variation and a low heritability. Environmental conditions during growth are thought to have long-term effects through 'metabolic programming'. Here we investigate whether nutritional conditions early in life can alter RMR in adulthood, and whether this is due to growth acceleration or the change in diet quality that prompts it. We manipulated dietary protein levels during the main growth period of zebra finches (Taeniopygia guttata) such that an episode of poor nutrition occurred with and without growth acceleration. This produced different growth trajectories but a similar adult body mass. Only the diet that induced growth acceleration resulted in a significant (19%) elevation of RMR at adulthood, despite all the birds having been on the same diet after the first month. This is the first study to show that dietary-induced differences in growth trajectories can have a long-term effect on adult metabolic rate. It suggests that modification of metabolic efficiency may be one of the mechanisms mediating the observed long-term costs of accelerated growth, and indicates links between early nutrition and the metabolic syndrome.

“…It is possible that migratory birds undergo a training effect accompanied by physiological changes, resulting in different muscle fibre composition or an improved supply with oxygen and nutrients. Also maintenance costs and basal metabolic rate are lowered during migration, as most organs are reduced in size (Piersma et al 1996;Biebach and Bauchinger 2003). This may reduce flight costs at least during long migratory flights.…”

“…In the intraspecific comparison there is little variation in morphology such as wing shape, but individual physiology may well change with spontaneous changes in mass, for instance on an annual basis. In the Red Knot (Calidris canutus) during the migration seasons major changes were reported for pectoral muscle mass, size of the stomach and intestines, and fat stores probably all having an impact on the basal metabolic rate (Piersma et al 1996;Biebach and Bauchinger 2003). In the interspecific comparison, both physiology and morphology represent adaptive states coevolved with body mass.…”

“…This may result in cognitive constraints ('demotivation'), which would reduce foraging activity (FOTHERINGHAM, 1998). If this is actually the case then those birds were starved, and starvation may lead to mass reduction of metabolic active tissue, and subsequently to a decline in BMR (DAAN et al, 1989;PIERSMA et al, 1996).…”

We measured energy expenditure in free-living great tits (Parus major) during the active (day) and the inactive period (night) with the aim of determining whether great tits compensate for energy costs made during periods of high activity in periods of low activity. If such compensation occurs, inferences from measurements of energy expenditure over a 24 h period, with regard to the energy costs of the different behavioural elements, may obscure relations between parental effort and energy expenditure. Also, energy budgets, based on estimates of time budgets combined with a xed cost for each behavioural category observed, may be unreliable if animals are able to compensate for energy costs made during periods of high activity in periods of low activity.Laboratory studies have revealed a reduction in resting metabolic rate (RMR) when birds are forced to work harder during the day, but it has not yet been investigated whether such nocturnal savings are also made under natural conditions.We manipulated brood size in a free-living population of great tits to create a difference in the demands of the nest, measured effort (feeding visits) and daily energy expenditure (DEE). In order to test whether compensation occurred we measured both DEE over 24 h, and resting metabolic rates (RMR) of female great tits at night. DEE and feeding rate differed between the experimental groups, being higher in females rearing enlarged broods, but we did not nd evidence of nocturnal saving.
