Molecular phylogenetic relationship of Stigmaeopsis spider mites (Acari : Tetranychidae) collected from Yamagata Prefecture
Get PDF論文(Article)We investigated the phylogenetic relationships of Stigmaeopsis spider mites (Acari: Tetranychidae) using sequence variation in the cytochrome oxidase subunit I (COI) region of mitochondria DNA. We sequenced a total of 32 samples including four samples of S. takahashii and ten of S. longus from Yamagata Prefecture. Phylogenetic analyses based on the neighbor-joining and the Bayesian method revealed that Stigmaeopsis consists of five monophyletic groups corresponding to each species. Among them, the monophyletic group of S. longus was further divided into two subgroups; one is the northern group composed of the samples from the Hokkaido and Tohoku districts, and the other is the southern group of the samples from the Tohoku, Hokuriku, Shikoku, and Kyushu districts. This suggests that the current distribution of this species has employed two routes of expansion. It is interesting that the samples of S. longus from Yamagata Prefecture were divided into the two groups. This implies that S. longus had multi-expanded patterns of distribution in this prefectur
On the Terrestrial Earthworm Fauna of Yamagata Prefecture, northeastern Japan
Get PDF論文(Article)We conducted to collect earthworms in order to clarify the earthworm fauna of Yamagata Prefecture. We could collect 16 species belonging to two families including two undescribed species from six localities. To our knowledge, it is first time to record Pheretima aokii, P. megascolidioides, P. micronaria and Aporrectodea caliginosa from Yamagata Prefecture. Therefore, except for two species which could not identified as known species, 18 valid species of earthworms exist in Yamagata Prefecture including our result. Keywords : earthworm fauna, Megascolecidae, Lumbricidae, Oligochaeta, Yamagata Prefectur

山形盆地の地下構造 : 村山市浮沼の調査試錐を中心として
Get PDFテクニカルレポートはじめに 山形大学教養部では,昭和58年から60年度まで,3ヶ年計画で文部省の特定研究を行うことになっている. このうち,地学分野では59年度に村山市浮沼で調査試錐を実施することができた.研究はまだ継続中であるが, この59年度の試錐結果の概要をここに御紹介したいと思う.さらに既存のデータとも合わせ,山形盆地全体の地下構造に関して従来の考え方を批判し,新たな提言を試みるつもりである.そして, これが,今後のたたき台となり,山形盆地の地下構造の真の姿が徐々に明らかにされていくことを期待するものである.本試錐調査をするに当たり,試錐地点を提供していただいた村山市西郷の板垣ちか氏,試錐調査を担当していただいた大手開発（株）の本田康夫氏並びに梅津栄紀氏にお礼申し上げます
