Description
Summary:Although hypoxia is a serious environmental concern for marine ecosystems globally, its biological effects on the benthic biota remain mostly unclear for some endangered species. To provide an deep understanding of the possible effects of hypoxia on the tri-spine horseshoe crab Tachypleus tridentatus, the cellular energy allocation (CEA) approach was utilized to examine the cellular responses and adaption potential of horseshoe crabs. We examined the energetic responses of T. tridentatus under low dissolved oxygen level (2 mg O2/L). The horseshoe crabs first experienced 14 days of hypoxic stress, and then recovered in a normal dissolved oxygen environment for 7 days. On the 7th and 14th day of hypoxic exposure, the levels of available energy, electron transport system activity, protein, lipids, and carbohydrates were decreased in T. tridentatus (p
