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 embryo and larval stages but pronounced at the juvenile life stage, suggesting that bioenergetic changes in pollution-adapted killifish manifest later in life. We also provide evidence that killifish from remediated sites are more sensitive to PAH exposure than killifish from nonremediated sites, suggesting loss of PAH tolerance following relaxed selection. Collectively, our data suggest that the fitness consequences associated with evolved resistance to anthropogenic stressors may manifest differently over time and depend on the magnitude of the selection pressure. This information can be valuable in effective risk and remediation assessments as well as in broadening our understanding of species responses to environmental change.
