Outline of Final Research Achievements

To effectively manage an invasive alien species, the red-billed Leiothrix, in Japan, we investigated the genetic structure at 5 microsatellite loci in 12 populations (N= 409 individuals). All populations showed relatively high heterozygosity. The numbers of alleles were larger in western populations, except Shikoku, and smaller in Aichi, Kochi and Tsukuba populations. The Aichi and Kochi populations differentiated greater from other populations. The analysis using the program STRUCTURE implied that the birds were divided into nine clusters and each of Kochi and Aichi populations was mainly consisted of individuals belonging to a specific cluster. The present preliminary study suggests that Kochi and Aichi populations have higher priority for elimination because they showed less gene flows among other populations.
