Compared with two congeners (H.nigrescens and H. kimurae ) and Onchodactylus japonicus , the historical distribution of H. takedai was associated with lower elevation, more gentle slopes lower annual rainfall, higher annual accumulated temperature, anshallow springsnow depts. H. takedai showed a preference for areas with a lower proportion of forest and higher proportion of rice paddies. H. takedai appeared to prefer swampy sites near villages in rural regions, i.e., satoyama landscapes. In logistic regression analysis, maximum slope, proportion of forest area, annual precipitation, March snow depth, and proportion of rice paddy area were important factors for predicting H. takedai occurrence. Based on these factors, we determined the amount of potential habitat available to this species in Ishikawa using a Max nt model, and found that highly suitable areas were distributed in the Noto Peninsula, especially in central Noto, and in hilly areas from Hakui to Nanao, montaneareas at the foot of Houdatsu Shimizu-cho, and the coastal area around Kaga. The distance from oak-dominated stands and March snow depth were particularly important predictor variables. Preservation of H. takedai will likely depend on the preservation of satoyama landscapes, wherein humans and nature coexist.}, pages = {23--31}, title = {石川県における絶滅危惧種ホクリクサンショウウオ(Hynobius takedai)の生息環境と生息適地の予測}, volume = {4}, year = {2021}, yomi = {オオニシ, ヤスホ and ヤナイ, セイジ} }
