摘要: Marine benthic polychaete Capitella sp. I is widely known to adapt polluted habitats; however, its response xenobiotics under hypoxic conditions has been rarely studied. This research aimed test the hypothesis that interactive effects of hypoxia and congener BDE-47 polybrominated diphenyl ethers (PBDE), which ubiquitous in marine sediments, may alter settlement I. Our results revealed condition, success growth body length larvae were significantly reduced compared those normoxia similar concentration. While no significant changes morphology settled noted both exposure conditions, presence could enhance growth. The present findings demonstrated environmentally realistic concentrations sediments affect settlement, which, turn, reduce recruitment subsequent population size ecosystem.
