Meghan S. Strange, M.S. ’15, recently published her thesis work in the Journal of Experimental Zoology (Strange, M.S., R.M. Bowden, C.F. Thompson, and S.K. Sakaluk. 2016. Pre- and postnatal effects of corticosterone on fitness-related traits and the timing of endogenous corticosterone production in a songbird. J. Exp. Zool. 325A: 347-359).
Her study was featured on the journal’s cover, with a photograph of her study species, the house wren. Strange tested two hypotheses concerning the fitness-related consequences of experimentally elevated corticosterone (the avian ‘stress’ hormone) during pre- and post-natal development in house wrens. She also documented the ontogeny of the stress response in nestlings.
Her results demonstrate that pre-natal exposure in the egg to maternal corticosterone is important in shaping offspring phenotype and long-term fitness.
