Research Abstract

Japanese populations of Rumina decollata are represented by only one haplotype, which is also known from Portugal, Spain and China. It may be anthropochorously introduced one time and unintentionally dispersed to other places in Japan. Self-fertilization is more favorable to alien species and it may bring great prosperity or rapid extinction. A limited distribution of the snail in Ainoshima Islet suggests that it was introduced recently, so continuous observation is necessary to evaluate an effect of the invasion of the snail against native molluscan ecosystem.
