Outline of Final Research Achievements

The purpose of the current study is to investigate whether and how loss of migration habit influence of phenotype of birds. A migrant bird, the barn swallow, is reported to be resident sometimes, and our own survey showed this can be happen in Japanese barn swallows. We are currently writing a manuscript to report the effect of migration on phenotype in the barn swallows. Also, we focused on the Pacific swallows, which are resident species, and found natural selection on several phenotypic traits during once-in-a-century severe winter. This study clarified strong selection on non-migratory species.

Academic Significance and Societal Importance of the Research Achievements

本研究は、都市域で見られる局所的な温度環境の変化が世界的な温暖化と合わせて鳥類の渡り行動に与える影響および、その派生効果について着目したものである。残念ながら、調査地のツバメの個体数減少により、当初予定していた充分な調査を行なうことは叶わなかったが、それでも得られたデータから、渡り行動の消失とその派生効果が示され、現在はその具体的な影響について論文化して近く投稿することを予定している。このことが明らかになれば、加速度的に侵攻する都市化と温暖化、およびその相互作用が生物にどのような影響を与えるのか、示すことができる。
