The presence of Ixodes pavlovskyi and I. pavlovskyi–borne microorganisms in Rishiri Island: an ecological survey
ABSTRACTRishiri Island, towering toward the Sea of Japan, has been volcanically dormant for approximately 8,000 years. This small inhabited island is free of middle- to large-sized wildlife and a crucial stopover for wild birds migrating along various routes of the East Asian Flyway. A 5-year survey...

ABSTRACTRishiri Island, towering toward the Sea of Japan, has been volcanically dormant for approximately 8,000 years.
