Description

<p>The goal of this survey was to elucidate the conservation-related ecology of Myotis yanbarensis and Murina ryukyuana on Okinawa Island. From fall 2017 to summer 2018 we conducted bat capture surveys using synthesized social calls as an acoustic lure. Although the acoustic lure increased the catch rate of Murina ryukyuana, the strength of this effect differed between seasons. Our capture of Myotis yanbarensis represents the first report of this species on Okinawa Island in 22 years. Although the acoustic lure was used, its effectiveness concerning Myotis yanbarenesis is unclear. Additionally, we attached VHF transmitters to captured bats in order to confirm roosts, critical habitat for bats. Murina ryukyuana roosted in various roost types including leaves, ferns, and tree cavities.Myotis yanbarensis used mainly tree cavities. On Okinawa Island, the distribution of Myotis yanbarensis may be more restricted than that of Murina ryukyuana. Further research is needed in order to clarify the ecology of these species and design conservation management plans.</p>
