“…High-cost foragers and individuals raised in large broods (e.g. Alonso-Alvarez et al 2006;Tschirren et al 2009;Verhulst et al 2006) usually experience negative effects on a variety of fitness-related traits, in particular under unfavourable adult conditions (e.g. Hendrickx et al 2003;Lens et al 2002;Talloen et al 2010).…”

Furthermore, increased foraging costs in adulthood result in physiological adjustments to save energy , and might therefore also affect innate immunity because of the associated energetic costs (Klasing 2004).…”

Long-term effects of unfavourable conditions during development can be expected to depend on the quality of the environment experienced by the same individuals during adulthood. Yet, in the majority of studies, long-term effects of early developmental conditions have been assessed under favourable adult conditions only. The immune system might be particularly vulnerable to early environmental conditions as its development, maintenance and use are thought to be energetically costly. Here, we studied the interactive effects of favourable and unfavourable conditions during nestling and adult stages on innate immunity (lysis and agglutination scores) of captive male and female zebra finches (Taeniopygia guttata). Nestling environmental conditions were manipulated by a brood size experiment, while a foraging cost treatment was imposed on the same individuals during adulthood. This combined treatment showed that innate immunity of adult zebra finches is affected by their early developmental conditions and varies between both sexes. Lysis scores, but not agglutination scores, were higher in individuals raised in small broods and in males. However, these effects were only present in birds that experienced low foraging costs. This study shows that the quality of the adult environment may shape the long-term consequences of early developmental conditions on innate immunity, as long-term effects of nestling environment were only evident under favourable adult conditions

“…However, the narrow-sense heritability of RMR has been shown to be low ( Nespolo et al 2003;Labocha et al 2004), and there is evidence that environmental effects early in development may influence metabolic rate at adulthood ( Verhulst et al 2006). The most probable cause of such an effect is the pattern of nutrition during growth and development.…”

“…Specifically, we predicted that those animals which had undergone accelerated growth, prompted by a change from a low-protein diet to a high-protein one, would show a significant perturbation of adult RMR in comparison with those experiencing a diet or dietary switch not associated with growth acceleration. The study was carried out on zebra finches Taeniopygia guttata, chosen because their RMR at adulthood has previously been found to be affected by the brood size in which they are reared (and hence possibly their access to food; Verhulst et al 2006) but is stable once adulthood is reached (Rønning et al 2005); moreover, they exhibit catch-up growth after early protein deprivation (Birkhead et al 1999;Blount et al 2003). We show for the first time that metabolic rate can be set by early growth trajectory, and that it is highest in animals that have earlier undergone accelerated growth.…”

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

et al. 2008

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.

Adverse environmental conditions can impact the life history trajectory of animals. Adaptive responses enable individuals to cope with unfavorable conditions, but altered metabolism and resource allocation can bear long-term costs. In songbirds, early developmental stress can cause lifelong changes in learned song, a culturally transmitted trait, and nestlings experiencing developmental stress develop smaller song control nucleus HVCs. We investigated whether nutrition-related developmental stress impacts neurogenesis in HVC, which may explain how poor nutrition leads to smaller HVC volume. We provided different quality diets (LOW and HIGH) by varying the husks-to-seeds ratio to zebra finch families for the first 35 days after the young hatched (PHD). At PHD14-18 and again at nutritional independence (PHD35), juveniles were injected with different cell division markers. To monitor growth, we took body measures at PHD10, 17, and 35. At PHD35 the number of newly recruited neurons in HVC and the rate of proliferation in the adjacent ventricular zone (VZ) were counted. Males raised on the LOW diet for their first weeks of life had significantly fewer new neurons in HVC than males raised on the HIGH diet. At the time when these new HVC neurons were born and labeled in the VZ (PHD17) the birds exposed to the LOW diet had significantly lower body mass. At PHD35 body mass or neuronal proliferation no longer differed. Our study shows that even transitory developmental stress can have negative consequences on the cellular processes underlying the development of neural circuits.
