Hypoxia: from molecular responses to ecosystem responses

摘要

Hypoxia affects thousands of km~2 of marine waters all over the world, and has caused mass mortality of marine animals, benthic defaunation and decline in fisheries production in many places. The severity, frequency occurrence and spatial scale of hypoxia have increased in the last few decades. Due to rapid human population growth and global warming, the problem of hypoxia is likely to become worse in the coming years. Molecular responses of marine animals to hypoxia are poorly known. In many animals, a haem protein serves as the Cellular sensor for oxygen, and reactive oxygen species are generated as signaling molecules.
