Bioenergetic Effects of Polycyclic Aromatic Hydrocarbon Resistance Manifest Later in Life in Offspring of Fundulus heteroclitus from the Elizabeth River.

ABSTRACT: Shifts in key physiological processes can confer resistance to chemical pollutants. However, these adaptations may come with certain trade-offs, such as altered energy metabolic processes, as evident in Atlantic killifish (Fundulus heteroclitus) in Virginia's Elizabeth River (ER) that have evolved resistance to polycyclic aromatic hydrocarbons (PAHs). We seek to understand the bioenergetic costs of PAH resistance among subpopulations of Atlantic killifish with differing contamination levels in order to examine how these changes manifest across multiple life stages and how these costs might be exacerbated by additional stressors. Bioenergetics data revealed differences in metabolic rates between offspring of PAH-resistant fish and reference fish were absent or minimal in both the emb
