Description

<p>Ancient murrelets breed and nest on vertical cliffs in the Teuri island, the population size of which is small and estimated from 161 to 299 individuals. Conservation management of the Teuri breeding population has been required but not established until now. The population has lacked for scientific data about ecological and genetic information owing to the difficulty in approach to nest sites. In 2016, during the breeding season, researchers collected blood of 30 individuals from the population, which enable us to investigate genetic characteristics of the Teuri population for conservation. Mitochondrial analysis revealed that Teuri population shared haplotype with Aleutian breeding population but did not shared with British Colombia and Kamchatka breeding populations. The results suggested that the Teuri and Aleutian populations should be separately managed for conservation from the others. Microsatellite analysis showed no evidence of low genetic diversity of Teuri population. We proposed a conservation plan by protection of the nesting sites in the Teuri island. Additionally, a wide range of conservation managements for ancient murrelets would be required, because the sea near Japan would be important area for their wintering habitat.</p>
