| Abstract;Since the population of Nypa fruticans at Funaura on the Iriomote Island was declared as a natural monument in 1959, it has been rapidly reduced in size. Its genetic diversity examined by the Random Amplified Polymorphic DNA(RAPD) method showed that all 28 "individuals" examined but one were genetically identical and had no diversity. They are thus considered clones derived from a single individual by vegetative propagation. Because flowers of a few "individuals" failed to set fertile seeds in 1998, the species is likely to be self-incompatible. A totality of data available indicates that the population at Funaura is at a crisis of extinction. (author abst.) |
