Abstract

Energetic cost of growth determines how much food-derived energy is needed to produce a given amount of new biomass and thereby influences energy transduction between trophic levels. Growth and development are regulated by hormones and are therefore sensitive to changes in temperature and environmental endocrine disruption. Here we show that the endocrine disruptor bisphenol A (BPA) at an environmentally relevant concentration (10 μg l⁻¹) decreased fish (Danio rerio) size at 30 °C water temperature. Under the same conditions, it significantly increased metabolic rates and the energetic cost of growth across development. By contrast, BPA decreased the cost of growth at cooler temperatures (24 °C). BPA-mediated changes in cost of growth were not associated with mitochondrial efficiency (P/O ratios [i.e. adenosine diphosphate (ADP) used/oxygen consumed] and respiratory control ratios) although BPA did increase mitochondrial proton leak. In females, BPA decreased age at maturity at 24 °C but increased it at 30 °C, and it decreased the gonadosomatic index suggesting reduced investment into reproduction. Our data reveal a potentially serious emerging problem: increasing water temperatures resulting from climate warming together with endocrine disruption from plastic pollution can impact animal growth efficiency, and hence the dynamics and resilience of animal populations and the services these provide.
