Physiological Plasticity and Tolerance of Fundulid Killifish Species to Aquatic Hypoxia

Aquatic hypoxia is a naturally occurring phenomenon in waters subject to high primary production, eutrophication, and salinity‐derived stratification. Fish utilize a suite of physiological responses in order to cope with aquatic hypoxia. Species that regularly experience repeated bouts of hypoxia may rely more heavily on compensatory responses in order to survive. We hypothesized that species from hypoxia‐prone environments such as estuaries …
