The importance of female phenotype in determining reproductive potential and recruitment in Atlantic coast striped bass (Morone saxatilis)
The influence of female phenotype on the reproductive potential of Atlantic coast striped bass is addressed in three key areas of research. The importance of the environment in shaping maternal phenotype was evaluated using a spawning stock time-series to evaluate possible environmental drivers of …

Effects of Maternal Stress and Cortisol Treatment on Offspring Anxiety Behaviour and Stress Responses In Zebrafish (Danio rerio) and Largemouth Bass (Micropterus salmoides)
… to spawn has been reported to have effects on offspring phenotype. Cortisol, the main glucocorticoid (GC) stress hormone, has been proposed as a potential mediator of such effects because of its organizational role in early teleost development. The present thesis tested whether maternal social …

Individual and Interactive Impacts of Mercury and Agriculture on Reproduction in a Freshwater Turtle, Chelydra serpentina
… of incubation temperature on survival and offspring phenotype. These same disturbed sites are often contaminated by pollutants and turtles can incorporate high levels of pollutants into their eggs which negatively impact hatch success. For my M.S. research, I investigated turtle nest site …

Maternal investment tactics in cooperative breeding systems
… multiple individuals contribute to the care of offspring, the optimum level of investment for each carer depends on the behaviour of the others. Previous theoretical and empirical work has largely focused on carer contributions within a single stage of a breeding attempt, neglecting the …

The neuroendocrine and molecular mechanisms underlying stress-induced maternal effects in the threespine stickleback
Non-genetic maternal effects occur when offspring phenotype is influenced non-genetically by a mother’s phenotype. Exposure of mothers to external stressors, for example, can influence the expression of a wide array of offspring traits essential for survival, including growth, morphology, and …

Roles of dietary antioxidants and oxidative stress in mediating fitness related traits in birds
… dietary antioxidant availability on maternal and offspring phenotype and fitness in blue tits Cyanistes caeruleus. I also investigated the role of dietary antioxidants in reducing oxidative stress produced during exercise in adult captive budgerigars Melopsittacus undulatus. Supplementing blue tit …
