Recurring outbreaks of crown-of-thorns starfish (COTS) severely damage healthy corals, especially in the Western Pacific Ocean. To obtain a better understanding of population genetics of COTS and historical colonization across the Pacific Ocean, complete mitochondrial genomes were sequenced from 243 individuals collected in 11 reef regions. Our results indicate that Pacific COTS (Acanthaster cf. solaris) comprise two major clades, an East-Central Pacific (ECP) clade and a Pan-Pacific (PP) clade, separation of which was supported by high bootstrap value. The ECP clade consists of COTS from French Polynesia, Fiji, Vanuatu and the Great Barrier Reef (GBR). The Hawaii population is unique within this clade, while California COTS are included in EPC clade. On the other hand, the PP clade comprises multiple lineages that contain COTS from Vietnam, the Philippines, Japan, Papua New Guinea, Micronesia, the Marshall Islands, GBR, Vanuatu, Fiji and French Polynesia. For example, a lineage of the

Under the background of global warming, the energy budget of the earth is out of balance with more than 90% of additional heat entering the ocean.
The tropical Pacific Ocean has an important influence on the global tropical climate and the climate of China, and the tropical Pacific Western Boundary Currents (WBCs) that flow through it plays an important role in the climate system. Large-scale ocean circulation redistributes ocean heat and mass and is hence one of the basic dynamic processes that shape the earth s Marine environment. The tropical Pacific WBCs system is a key part of the global ocean circulation system. Accurate assessment of the variation of the tropical Pacific WBCs is of much significance for bett
