| Outline of Research at the Start |
本研究では，人為的環境や農地などにおける景観構造が，コウモリ類の活動や移動に及ぼす影響を，バイオロギング・音響・食性分析から明らかにすることを目的としている．多くが不明なコウモリの移動生態の解明だけでなく，コウモリをモデル動物とした景観生態学的研究を国内で確立することを目指している．具体的には，バイオロギングによる絶滅危惧種ヤマコウモリの景観利用について，北海道の都市や農地などという異なる景観構造を調査対象地とし，夜間の採餌ルートを調査する．GIS解析より採餌環境や効率と景観構造の関連性から，人為的な景観構造が野生動物の環境利用に及ぼす影響を検討する．

| Outline of Annual Research Achievements |
From April 2021 until my leave on August 13th I have focused on processing fecal samples from individual bats and from colonies that were collected in the previous years. I also taught a student how to use this method in order to keep collaborations regarding diet analyses in Japan while I’m back in Germany. During 2021 further fecal samples have been collected by students for this project from colonies of Nyctalus aviator in urban and semi-natural landscapes in Hokkaido and in similar landscapes in Fukui Prefecture from colonies of Rhinolophus nippon.
In addition, I have continued to work on various manuscripts that have been published in December 2021 and in early 2022. One of these manuscripts I have written as a first author. This manuscript was dealing with dietary differences between two Japanese bat species that were specialized on forest habitats and occurred together in space and time.
The available GPS-data from bats that were tracked from the year 2015 to 2020 is under analysis. A majority of statistical tests on GPS-data from Japanese horseshoe bats have been presented at the European Bat Research Symposium in May 2021. The corresponding manuscript is in preparation.
