Stress increases adrenal glucocorticoid secretion, and chronic elevation of glucocorticoids can have detrimental effects on the brain. Dehydroepiandrosterone (DHEA) is an androgen precursor synthesized in the adrenal glands, gonads or the brain and has anti-glucocorticoid properties. However, little is known about the role of DHEA in the stress response, particularly in the brain. In Chapter 2, I validated a solid phase extraction technique for extracting steroids from lipid-rich brain tissue and plasma of songbirds. In Chapter 3, I demonstrated that acute stress had statistically signific

Thiobarbituric acid reactive species (TBARS) concentrations were increased in both stressed and pair-fed rats.

In a variety of vertebrate species, early life environmental cues are important drivers of an individual’s phenotypic trajectories, priming physiological pathways, with consequences for growth, reproductive-related traits and lifespan. These phenotypic responses are believed to be adaptive in the short-term, but may impinge on health and survival over the long-term. Much of the work in this field has focused on the potential constraints imposed on animals after exposure to early life adversities, including nutritional deficit, sibling competition, and high predator pressure.

Quantitication of stress requires the use of a stress indicator that is easy to measure, and which can be readily interpreted in terms of the potential long-term effects to an organism. This study evaluates the suitability of metabolic rate as an indicator of the stress response in fish. By comparing the metabolic with the cortisol stress response, the most commonly used indicator of stress in fish, it was possible to assess the suitability of metabolic rate as a stress indicator. Changes in metabolic rate were used to predict the long-term effects of transport-related stressors. This study al
