...Bernard B. Rees; Jessica E. Reemeyer; Brian A. Irving ABSTRACT This study asked whether interindividual variation in maximum and standard aerobic metabolic rates of the Gulf killifish, Fundulus grandis , correlates with gill morphology and cardiac mitochondrial bioenergetics, traits reflecting...

Sample size was N=10 for each group, except 7 days normoxia (N=20). Constant hypoxia had numerous effects on gill morphology. Because body mass has...

Fish species from rapid-flow habitats were also characterized by less plasticity in swim performance and gill morphology in response to hypoxia...
