Ryukyu Islands

Goby Poisoning. At least one species of the family Gobiidae, namely Gobius criniger, has been found to contain tetrodotoxin (89, 90). Fatalities to humans and animals have been reported in Taiwan, and this goby is known to be toxic in the Philippines and Ryukyu Islands.

Two morphs have been identified in this species. The black morph is found in the Ryukyu islands and Taiwan, while the brown morph occurs in southern China, the Philippines and Indonesia (Lemeunier et al., 1986). Partial reproductive isolation, based mainly on... 

Kaneshima (1962) has indicated that the deposits on Ryukyu Island contain very little uranium when compared with continentel deposits, and this suggests that accumulation of uranium is a secondsiry or diagenetic process,...

The soybeans grown in Japan were derived from the intermingling of two possible sources of germplasm—Korea and Central China. The first points of contact were probably in Kyushu, and from there the soybean moved slowly northward to Hokkaido. In addition, the soybean moved southward from Kyushu to the Ryukyu Islands, where they came in contact with the soybeans moving northward from Taiwan. The earliest Japanese reference to the soybean is in KoJiKi or Records of Ancient Matters, which was published in 712 ce (Chamberlain, 1906). 

The overall objective of this chapter is to review the past, present, and future role of the sweet potato (Ipomoea batatas [L.] Lam) in human nutrition. Specifically, the chapter describes the role of the sweet potato in human diets outlines the biochemical and nutritional composition of the sweet potato with emphasis on its (3-carotene and anthocyanin contents highlights sweet potato utilization, and its potential as value-added products in human food systems and demonstrates the potential of the sweet potato in the African context. Early records have indicated that the sweet potato is a staple food source for many indigenous populations in Central and South Americas, Ryukyu Island, Africa, the Caribbean, the Maori people, Hawaiians, and Papua New Guineans. Protein contents of sweet potato leaves and roots range from 4.0% to 27.0% and 1.0% to 9.0%, respectively. The sweet potato could be considered as an excellent novel source of natural health-promoting compounds, such as p-carotene and anthocyanins, for the functional food market. 

Okinawa Trough, the Ryukyu island arc, and the Rjmkyu trench, it makes up another Trench-Arc-Basin system in the West Pacific Ocean, which links northwards with the Japanese island arc and connects southwards with the Taiwan-Philippine island arc. The northwest shelf cormects with the Yellow Sea and between them is the Changjiang River delta, with a water depth of about 50 100 m.
