EAPSI: Investigating the Drivers of Invasive Raccoon Spread in Japan and its Effects on the Native Raccoon Dog

入侵物种是仅次于栖息地破坏的全球物种灭绝的第二大原因，它们对岛屿的影响尤其强烈。自1970年S引入日本以来，这种北美浣熊已经渗透到全国的森林和城市地区，并构成了一个重大的野生动物管理问题。它被认为会影响许多当地物种，包括魅力十足的浣熊，但它的影响还没有被很好地了解。这位研究人员将与横滨国立大学的入侵物种和空间建模专家、横滨国立大学的小池文登教授合作，调查导致浣熊S传播的因素。研究小组将使用各种环境变量来模拟浣熊的运动。他们还将使用放置在模型预测的区域的摄像头‘陷阱’来确定对浣熊狗的影响。这项研究将为日本和其他地区的入侵物种管理提供有用的建模技术和现场方法。入侵物种是仅次于栖息地破坏的全球物种灭绝的第二大原因，它们对特有现象严重、行动受限的岛屿的影响尤其强烈。自1970年S引入日本以来，这种北美浣熊已经渗透到全国的森林和城市地区，并构成了一个重大的野生动物管理问题。它被认为会影响许多当地物种，包括魅力十足的浣熊，但它的影响还没有被很好地了解。研究人员将与横滨国立大学教授、入侵物种和空间建模专家小池文雄合作，通过模拟浣熊在不同复杂程度(例如土地利用、生态位模型)的不同阻力表面上的运动来研究入侵传播的驱动因素。他们将使用放置在模型预测区域的相机陷阱来测量这两个物种的数量，并量化对浣熊的影响。这项研究将为日本和其他地方的入侵物种管理提供有用的建模技术和现场方法。该奖项由东亚和太平洋夏季学院计划资助一名美国研究生的夏季研究，由NSF和日本科学促进会共同资助。

Invasive species are the second largest cause of global species extinction after habitat destruction, and they have an especially strong impact on islands. The North American raccoon, introduced to Japan in the 1970?s, has since infiltrated forested and urban areas country-wide and poses a significant wildlife management problem. It is thought to affect many native species, including the charismatic raccoon dog, but its impacts are not well understood. The researcher will work with Professor Fumito Koike of Yokohama National University, an expert on invasive species and spatial modeling, to investigate the factors causing the raccoon?s spread. The research team will use various environmental variables to model raccoon movement. They will also use camera 'traps' placed in areas predicted by the model to determine impact on the raccoon dog. This research will contribute modeling techniques and field methods useful for invasive species management both in Japan and elsewhere.Invasive species are the second largest cause of global species extinction after habitat destruction, and they have an especially strong impact on islands, where endemism is high and movement is restricted. The North American raccoon, introduced to Japan in the 1970?s, has since infiltrated forested and urban areas country-wide and poses a significant wildlife management problem. It is thought to affect many native species, including the charismatic raccoon dog, but its impacts are not well understood. The researcher will work with Professor Fumito Koike of Yokohama National University, an expert on invasive species and spatial modeling, to investigate the drivers of invasive spread by simulating raccoon movement over various resistance surfaces of differing complexity (e.g. land use, ecological niche models). They will use camera traps placed in areas predicted by the model to measure both species' abundances and quantify impact on the raccoon dog. This research will contribute modeling techniques and field methods useful for invasive species management both in Japan and elsewhere.This award under the East Asia and Pacific Summer Institutes program supports summer research by a U.S. graduate student and is jointly funded by NSF and the Japan Society for the Promotion of Science.
