富山県におけるアオドウガネとヤマトアオドウガネの生息状況および分布可能域の比較

Recently, Anomala albopilosa expands its distribution northward in Honshu, displacing related endemic species such as A. japonica, however, the distribution of A. albopilosa in Toyama Prefecture is unknown well. Then, we investigated the records and distribution of A. albopilosa and A. japonica in Toyama Prefecture, A. albopilosa were found in the central area of the prefecture from the early 2000s at intervals of less than five years. Furthermore, as of 2021, A. albopilosa were confirmed in a wide range from the western area to the central area of Toyama prefecture and in Kurobe City. As a result of estimating the distribution area of A. albopilosa with MaxEnt, the distribution area of A. albopilosa almost completely overlapped with the one of A. japonica. On the other hand, the occurrence peaks of adult of both species differed by about two months. <br> 図S1a：アオドウにおける各環境変数が分布推定に与えた影響（重要度）． <br> 図S1b：ヤマトにおける各環境変数が分布推定に与えた影響（重要度）． <br> 表S1：2021年野外調査結果生データ．
