Population structure of the large Japanese field mouse, Apodemus speciosus (Rodentia: Muridae), in suburban landscape, based on mitochondrial D-loop sequences.

摘要: Genetic structure of the large Japanese field mouse populations in suburban landscape West Tokyo, Japan was determined using mitochondrial DNA control region sequence. Samples were collected from six habitats linked by forests and green tract along Tama River, two segregated urban areas those continuous habitats. Thirty-five haplotypes detected 221 animals. Four to eight found within each local population belonging landscape. Some shared or three adjacent populations. On other hand, isolated occupied one indigenous haplotypes. Significant genetic differentiation between all pairs populations, except for pair habitats, analysis molecular variance (amova). The geographical distance did not explain pairwise FST-values among higher than habitat, regardless distance. results this study demonstrated quantitatively that inhibit migration Apodemus speciosus, whereas a linear river functions as corridor. Moreover, it preserves metapopulation A. speciosus well corridors
