Seawater carbonate chemistry and physiology of competing temperate and coral reef fishes

We used a controlled laboratory experiment to test the concurrent effects of projected future summer and winter ocean temperatures, ocean acidification, and novel species interaction on the physiology of range-extending tropical and co-shoaling native temperate fish species across a 38-day exposure period. Physiological proxies including total antioxidant capacity, malondialdehyde, fulton's condition index, hepatosomatic index, stomach fullness and total lipid content were measured.本研究采用控制实验室实验方法，探究预测的未来夏季、冬季海洋水温、海洋酸化以及新型物种互作对分布范围扩张的热带鱼类与结伴群栖的本土温带鱼类生理特征的协同影响，实验暴露周期为38天。实验测定了多项生理替代指标，包括总抗氧化能力、丙二醛、富尔顿条件指数（Fulton's condition index）、肝体指数（Hepatosomatic Index）、胃饱满度及总脂质含量。
