Dietary antioxidants can improve escape-response performance in adult vertebrates, but whether juveniles receive similar benefits remains untested. Here, we investigated the effect of two dietary carotenoids ( β -carotene and lutein) on the escape-response of juvenile corroboree frogs (Pseudophryne corroboree) at two developmental points (early and...

Many animals hibernate to survive winter conditions, however, arousal from hibernation generates reactive oxygen species (ROS) that can cause oxidative stress. Dietary antioxidants, like carotenoids, may reduce oxidative stress during arousal from hibernation, and assist with post-hibernation recovery and performance. We tested the effect of carote...

Dietary carotenoids are expected to improve vertebrate growth and development, though evidence for beneficial effects remains limited. One reason for this might be that few studies have directly compared the effects of carotenoids from different classes (carotenes versus xanthophylls) at more than one dose. Here, we tested the effect of two doses o...

Escape-response behaviour is essential to ensure an individual's survival during a predator attack, however, these behaviours are energetically costly and may cause oxidative stress. Oxidative stress can be reduced by supplementing an individual's diet with exogenous antioxidants or through regular moderate exercise training, which stimulates the u...

Nutritional conditions experienced by an individual are known to affect phenotype and performance. In particular, dietary carotenoids influence vertebrate immune function, vision and coloration and have recently been suggested to enhance exercise performance. Despite growing interest in investigating the effect of dietary carotenoids on exercise pe...

Organismal performance can be significantly affected by the nutritional conditions experienced during different life-stages. The Silver Spoon Hypothesis predicts that individuals will always perform better as adults when they experience advantageous conditions during development. In contrast, the Environmental Matching Hypothesis predicts that indi...
