How do early environment, diet and physical activity interact to determine bone development in young children?
Aims: To examine the interaction of maternal factors (body composition, physical activity, diet and cigarette consumption) with childhood factors (body composition, diet & physical activity) in the determination of bone mineral accrual by aged 6 years, assessed by a) bone densitometry b) hip …

Paediatric asthma and wheeze: early life origins
… asthma and wheeze. Factors creating a suboptimal early environment may persistently alter the structure and function of the immune and respiratory systems.<br/>This thesis explored the early life origins of paediatric asthma and wheeze in a large, prospective mother-child cohort. In particular, …

Post-natal environmental effects on behaviour in the zebra finch (Taeniopygia guttata)
Due to mounting evidence that the early environment experienced by a juvenile can affect the morphology and physiology of the adult, there is currently great interest in how environmental variability may shape the behavioural phenotype, and whether such shaping has adaptive benefits. It is clear …

Winnicott, Bowlby and Rogers: the development of the self in relation to others
… of people who are homeless is trauma in the early environment. The theories of Winnicott, Bowlby and Rogers are critically analysed and compared due to their focus on the significance of the relationship in development and the influence of the external environment. The thesis is divided into …

Early Adversity and Cardiovascular Stress Response: Stress Reactivity Or Biological Sensitivity to Context
… hypothesis (SRH) posits highly stressful early environments contribute to exaggerated cardiovascular (CV) reactivity and/or slower CV recovery, which in turn contributes to CV disease. These associations are well-supported in the literature; however, a growing number of studies have …

MATERNAL EFFECTS AND SEXUAL SELECTION IN THE HELICONIA BUG, LEPTOSCELIS TRICOLOR (HEMIPTERA: COREIDAE)
The early environment experienced by organisms can have significant phenotypic effects that persist throughout life. Parents, mothers in particular, commonly determine these early environments. Maternal effects, or the influence of maternal phenotypes on offspring phenotypes, are therefore likely …

The effects of environmental switchovers between enrichment and impoverishment on brain and behavior in mice
<p>Rearing rodents or primates in environments that are comparatively enriched or impoverished results in often impressive physiological and anatomical changes after a certain period of exposure. However, the anatomical and biochemical characteristics that respond to environmental experience …
