Status
Rhodeus ocellatus kurumeus (Nippon baratanago) was widely distributed in small ponds, reservoir, and creeks in Kyushu and the western part of Japan. However, since Rhodeus ocellatus ocellatus (Tairiku baratanago) was introduced, the population of Tairiku baratanago has been increasing dramatically all over Japan. By coexisting those two species in many area it tended to occur hybridization easily.

In fact hybridization and subsequent gene introgression has been observed within these subspecies in Kashima and Ogori. Because of these interbreeding events the number of R.o.kurumeus has dramatically declined all over Japan and now the population of R. o. kurumeus (Nippon baratanago) is in danger of extinction. In 1994 R. o. kurumeus (R. o. smithi, Nippon baratanago) was on the IUCN Red List as an endangered species, and now it is critically Endangered. Nippon baratanago (R. o. kurumeus) is also listed as a critically endangered species on the Japanese Red Data Book.

Famous quotes containing the word status:
“His Majesty’s Government view with favour the establishment in Palestine of a national home for the Jewish people, and will use their best endeavours to facilitate the achievement of this object, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country.”
—A.J. (Arthur James)
“Anthropologists have found that around the world whatever is considered “men’s work” is almost universally given higher status than “women’s work.” If in one culture it is men who build houses and women who make baskets, then that culture will see house-building as more important. In another culture, perhaps right next door, the reverse may be true, and basket- weaving will have higher social status than house-building.”
—Mary Stewart Van Leeuwen. Excerpted from, Gender Grace: Love, Work, and Parenting in a Changing World (1990)
“[In early adolescence] she becomes acutely aware of herself as a being perceived by others, judged by others, though she herself is the harshest judge, quick to list her physical flaws, quick to undervalue and under-rate herself not only in terms of physical appearance but across a wide range of talents, capacities and even social status, whereas boys of the same age will cite their abilities, their talents and their social status pretty accurately.”
—Terri Apter (20th century)
