| To examine the origin of Callosciurus erythraeus introduced to Japan, we compared mitochondrial DNA control region sequences of eight haplotypes from Japan with those of 42 haplotypes from Taiwan. There were two distinct phylogroups in Japan. Six haplotypes from Japan were included in the Taiwan population, suggesting that they could have been introduced from Taiwan. Two haplotypes, however, were distantly related to the cluster consisting of all Taiwanese haplotypes and six Japanese haplotypes. The uncorrected genetic distances (5.2-5.7%) between these two haplotypes and the out-group (Callosciurus finlaysonii from Laos) were less than those (8.3-9.8%) between these two haplotypes and the cluster consisting of the other six Japanese haplotypes and all... |

| The ranges of pronation/supination of forearms in raccoons, raccoon dogs and red pandas were nondestructively examined. Three carcasses of each species were used for CT analysis, and the left forearms were scanned with a CT scanner in two positions: maximal supination and maximal pronation. Scanning data were reconstructed into three-dimensional images, cross-sectional images were extracted at the position that shows the largest area in the distal part of ulna, and then, the centroids of each cross section of the radius and ulna were detected. CT images of two positions were superimposed, by overlapping the outlines of each ulna, and then, the centroids were connected by lines to measure the angle of rotation, as an index of range of mobility. The... |

| ロシアの国家自然保護区機関の管轄する「国後島自然保護区クリリスキー」によって，保全・研究・環境教育を目的とした「ストルボフスキー生態観察路」が2001年に国後島中部に設置された．現在でも「クリリスキー」が本生態観察路の管理・整備を担当している．本生態観察路の優占樹種はオヒョウUlmus laciniata，ハルニレUlmus davidiana，エゾイタヤAcer pictum，ケヤマハンノキAlnus hirsuta であり，林床ではクマイザサSasa senanensis，オニシモツケFilipendula camtschatica，エゾイラクサUrtica platyphyllaとアキタブキPetasites japonicusが小班状に優占する．昆虫類では多くの甲虫類およびチョウ類種が確認されているが，国後島の他地域と比べた場合，特にチョウ類の種数が多いことが報告されている．鳥類については，本生態観察路を含む国後島中部から46種が確認されている．国後島には26種の陸棲哺乳類が生息するが，2015年8月15日～16日に本観察路で実施した哺乳類調査の結果，シマリスTamias sibiricus 1個体，キツネVulpes vulpesの糞を12個（この内10個にはネズミ類の体毛が多く含まれていた），クロテンMartes zibellinaの糞を1個，さらにヒグマUrsus arctosの糞1個を確認することができた．本観察路の自然は良く保全されており，少なくとも数種の哺乳類種に利用されていることが明らかになったが，同時にヒグマによる人身事故，およびキツネの糞を介したヒトへのエキノコックス症感染の可能性も危惧され，今後島民に対する適切な啓蒙活動が必要であることが示唆された． |
