growth
- Oxidative status and telomere length are related to somatic and physiological maturation in chicks of European starlings (Sturnus vulgaris)
Summary: Physiological maturation in birds, prior to fledging may occur at the expense of telomere length when growth occurs under sub-optimal environmental conditions.
- Divergent mechanisms for regulating growth and development after imaginal disc damage in the tobacco hornworm, Manduca sexta
Highlighted Article: Manduca sexta is proposed as a new model to study the effects of imaginal disc damage on developmental timing. After disc damage, critical weight is altered although growth rate is not, and juvenile hormone appears uncoupled from critical mass.
- Ontogenetic scaling of pelvic limb muscles, tendons and locomotor economy in the ostrich (Struthio camelus)
Summary: The ontogenetic scaling of muscle–tendon morphology and tendon material properties suggests maintained or relatively increased muscle force generation, increased elastic energy storage and locomotor economy in adult versus juvenile ostriches.
- Repeated stimulation of the pituitary–adrenal axis alters offspring phenotype of a wild passerine
Summary: Developmental stress has negative effects on pied flycatcher offspring growth and physiology, but may have short-term benefits on performance by enhancing antipredator behaviour.
- The importance of incorporating natural thermal variation when evaluating physiological performance in wild species
Summary: Physiological responses associated with stable temperatures are distinct from those in thermally variable environments and we need to understand these differences to truly predict how animals will respond to climate change.
- Growth hormone transgenesis in coho salmon disrupts muscle immune function impacting cross-talk with growth systems
Summary: Growth hormone transgenesis in coho salmon alters the immune response of skeletal muscle, leading to a disruption in normal cross-talk between the growth and immune systems.
- Independent and combined effects of egg pro- and anti-oxidants on gull chick phenotype
Summary: Supplementation of either vitamin E or corticosterone in the egg reduces body mass of gull hatchlings; combined administration of the two compounds nullifies their independent effects.
- Differences in stress and disease resilience related to emergence time for first feeding in farmed rainbow trout (Oncorhynchus mykiss)
Summary: The neuroendocrine response to acute stress and repeated stress of farmed juvenile rainbow trout is related to their individual time of emergence, but has no influence on their performance in captivity.
- Long-term programming effect of embryonic hypoxia exposure and high-carbohydrate diet at first feeding on glucose metabolism in juvenile rainbow trout
Summary: Embryonic hypoxia and dietary stimuli can affect growth performance and the mRNA levels of glucose-metabolism-related genes in juvenile rainbow trout.
