Research Abstract

The factors related to the invasion success of introduced Zaccoplatypus was examined from the viewpoints of genetics, ecology and morphology. Not only was the degree of invasion success decreased, but also feeding ecology was negatively impacted by the presence of Plecoglossus altivelis. In DNA analyses, it was found that most of the introduced populations are of Lake Biwa origin and their effective population sizes are positively correlated to the degree of invasion success. In addition, a few loci seem to contribute to the differentiation in morphological characters related to feeding in the invasion success of Z. platypus
