Dissolved oxygen levels in coastal areas have changed more than any other environmental variable during the past few decades, leading to widespread hypoxia. Crustaceans are among the most sensitive organisms to hypoxia and could therefore act as important indicator species of a healthy environment. Knowledge of their behavioural and physiological responses will be invaluable when predicting long-term effects of hypoxia on benthic communities. In general crustaceans respond to a decline in oxygen tension by increasing ventilation rate in an attempt to maintain a stable oxygen (O

在过去的几十年里，沿海地区溶解氧水平的变化比任何其他环境变量都要大，导致广泛的缺氧。甲壳类动物是对缺氧最敏感的生物之一，因此可以作为健康环境的重要指示物种。在预测缺氧对底栖生物群落的长期影响时，了解它们的行为和生理反应将是非常宝贵的。一般来说，甲壳类动物对氧张力下降的反应是增加通气率，试图维持稳定的氧（O
