Research Overview

Large-scale ecosystem management such as eradication of invasive alien species and wildlife damage control is an increasing issue. If a management action is planned properly, it can be considered as a large-scale field manipulation experiment. Then, we will be able to obtain not only understandings about dynamics of the organisms but also decision-support information for the management. My research theme is connecting data and decision-making in ecosystem management using ecological models. My specific interests are management of invasive alien tree species in the Bonin Islands, eradication of the small Asian mongoose in Amami Island, and population management of the bear.
