Abstract

<p>The effects of the invasive alien species such as Oryctes rhinoceros and Anoplolepis gracilipes on the native species and the status of the native endemic species such as Daito flying fox and Oryctes hisamatsui on the Daito Islands of the Ryukyu Archipelago were investigated. The damage by O. rhinoceros has been decreasing with the implementation of its eradication project. Chinese fun palms grown as planted trees or solitary trees are prone to damage; a higher number of individuals growing in the shelter belt forest (Hagu-rin) are less damaged and less dead. This point should be taken into consideration for the future restoration of the forests. The yellow crazy ant is distributed throughout the entire Minami- and Kita-Daito Islands. Although this survey showed no effects on birds, the effects on crustaceans on Minami-Daito Island have been suggested. Therefore, continued survey is needed. The population of the endemic subspecies Daito's flying fox was found to be stable. On the contrary, the endemic O. hisamatsui has not been observed for 11 years and is threatened with extinction.</p>
