野生動物の生態や進化の仕組みを遺伝子解析を通して理解する研究室です

北海道から世界まで、自然と闘い調和しながら生きる命の在り方や多様性維持の仕組みの解明を目指しています。科学の力で得られた知識を、野生生物保全の分野で社会に還元することも大きな目標の一つです。

研究目標

野生動物は環境に大きく影響されながら生命を育んでいます。彼らの存在は我々の生活にも大きく関わっていますが、彼らの生態系や生物多様性の成り立ちについては未だ多くの謎が隠されています。本研究室では、自然界でこれら野生生物がどのように生き、どのように命を繋いできたのか、また人間活動とどう関わっているのか、生態・進化・遺伝・保全の観点から探ることを目標としています。

教授は無類のサケ科魚類好きですが、研究室メンバーが選ぶテーマは魚類はもちろん、哺乳類、鳥類から無脊椎生物に至るまで様々です。北大のオープンな環境で自由な発想と国際的な視点、周りの大自然を活かした研究を展開していきます。

    9th FSEGG Seminar (2022) June 24th (Fri), 13:00-14:00, room N11, Faculty of Agriculture, Hokkaido University “Ecology of chum salmon juvenile during their early marine life inferred from environmental DNA” speaker: Yuki MINEGISHI, Ph.D. (Associate Professor, Atmosphere and Ocean Research Institute, The University of Tokyo) The studies on chum salmon in Japan has been conducted mainly in Hokkaido. In contrast, not much attention has been paid to the chum salmon population in the northeast area of the Honshu Island, including the Sanriku-ria Coast, Iwate Prefecture. However, the environment in this area is clearly different from that of Hokkaido, such as high water temperature in the coastal areas and rivers and the steep topography consisting of many semi-closed small bays, which should result in the local characteristics of ecological and behavioral traits. To understand the local ecological characteristics of chum salmon in the Sanriku area, we have been performing various studies on this species in Otsuchi Town, Iwate Prefecture. In this seminar, the ecology of juvenile chum salmon inferred from environmental DNA will be presented. Salmon and trout research in Japan is concentrated in Hokkaido. On the other hand, regarding salmon populations in the Honshu/Tohoku region, in addition to the fact that this region is near the southern limit of its distribution, it has clearly different environmental conditions from those in Hokkaido, such as ria coastal topography and high river and coastal water temperatures in winter. Therefore, it is assumed that there are unique regional characteristics in the behavior and ecology of salmon such as migration, migration, spawning and early life history. Therefore, with the aim of clarifying the regional ecological characteristics of salmon along the northeastern Pacific coast of Honshu, various studies on salmon in Sanriku are being carried out, mainly in Otsuchi Town, Iwate Prefecture. In this seminar, we will introduce the ecology of juvenile salmon in Sanriku, which was clarified by research using environmental DNA. *For 2019-2021, the Evolutionary Society of Japan, the Salmonology Research Group, and the Annual Meeting of the Environmental DNA Society were hosted by the laboratory, so the FSEGG seminar was canceled.
