| Summary: | 碩士 === 國立新竹教育大學 === 人資處應用科學系教學碩士班 === 94 === The barn swallow (Hirundo rustica ) is a common summer breeder in Taiwan. Early spring in each year, there were about ten thousands of non-breeding individuals colonized in Puli. The relationships between the non-breeding Puli population and summer breeding populations in Taiwan were uncertain. Partial mitochondrial control region sequence (572bp) and cytochrome b sequence (906bp) were analyzed to elucidate their relationships. We had 137 samples from Puli and 5 other breeding populations around Taiwan. Higher haplotype diversity (Hd) and lower nucleotide (π) diversity was observed among these populations. Pairwise FST values and high gene flow revealed very low level of isolation between populations. According to the Mantel test of FST value and logarithmic scales of geographical distance between populations, insignificant negative correlation indicated that isolation by distance model is inconsistent in this study. Special geographical distribution pattern between populations were not detected in the geophylogenetical analysis. Minimum spanning network analysis suggest that the breeding populations in Taiwan are divided into north Taiwan group and central Taiwan group. Most part of Puli non-breeding individuals joined north Taiwan group, some individuals probably migrated to Japan indicated by some recoveries of banded birds in Japan.
