چکیده انگلیسی
The Gulf of Mexico was home to the Deepwater Horizon oil spill, and is also known to exhibit seasonal declines in oxygen availability. Oil exposure in fish is known to impact oxygen uptake through cardiac impairment, which raises questions about the additive effects of these two stressors. Here we explore this question on the Atlantic croaker using two measures of hypoxia tolerance: critical oxygen threshold (Pcrit), and time to loss of equilibrium (LOE). We first demonstrated that 24â¯h exposure to 10.1 and 23.2â¯Î¼gâ¯lâ1 ΣPAH50 significantly impaired oxygen uptake. There was no effect of exposure on Pcrit or LOE. Exposure did result in significantly different repeatability between pre- and post-exposure Pcrit, suggesting that hypoxia tolerant individual may see greater impacts following exposure. These results suggest oil exposure does not have wide scale detrimental outcomes for hypoxia tolerance in fish, yet there may be fine scale impairments of ecological significance.
