Combined effects of crude oil exposure and warming on eggs and larvae of an arctic forage fish

Abstract Climate change, along with environmental pollution, can act synergistically on an organism to amplify adverse effects of exposure. The Arctic is undergoing profound climatic change and an increase in human activity, resulting in a heightened risk of accidental oil spills. Embryos and larvae...
