sinensis），クビワコウモリ（Eptesicus japonensis）の分布を音声解析により明らかにした．本研究では，これ ら３種の既知のねぐらにおいて出洞時の探索音声（モデル音声）をTime Expansion 型バットディテクターを 用いて録音したものを基準音声として音声解析を行い，県内37ヶ所で採集した1,078コールについて種判別を 試みた．さらに，クラスター分析，正準判別分析および機械学習により種判別の信頼性について検討した．そ の結果，クラスター分析を使った集団間の距離による判別評価でヤマコウモリ10ヶ所，ヒナコウモリ７ケ所お よびクビワコウモリ７ケ所を新たに確認した．また，正準判別分析と機械学習による判別率はいずれの種も 90％以上と高かった．以上から，これら３種について音声解析を用いて高精度に分布調査を行うことが可能で あることが示された．", "subitem_description_language": "ja", "subitem_description_type": "Abstract"}]}, "item_10_description_30": {"attribute_name": "資源タイプ（コンテンツの種類）", "attribute_value_mlt":
