The presence of predators alone is enough to negatively influence prey population dynamics by inducing costly defensive strategies. In seasonal populations, the effects of predator-induced fear carries over between seasons to dramatically decrease reproductive output. Understanding the underlying mechanisms that influence reproduction in seasonal populations is vital to the conservation and management of migratory species. For my undergraduate thesis, I will use ‘seaonalized’ laboratory populations of the common fruit fly, Drosophila melanogaster, to observe how the presence of predators in the non-breeding season alters activity levels, vigilance behaviour and corazonin (stress hormone) gene expression over the course of their adult life.
