Impacts of Flood Disturbance on the Dynamics of Basin-Scale Swimming Fish Migration in Mountainous Streams

Autor: Morihiro Harada, Shigeya Nagayama

Publikováno v: Water, Vol 14, Iss 4, p 538 (2022)

This study investigated the response of sweetfish (Plecoglossus altivelis), a species that migrates dynamically throughout a river basin, to two flood events during the summer of 2020 in the Nagara River, located in the central region of Japan. By co

Autor: Shigeya Nagayama, Nobuo Ishiyama, Taro Seno, Hideyuki Kawai, Yoichi Kawaguchi, Daisuke Nakano, Futoshi Nakamura

Publikováno v: Water, Vol 12, Iss 12, p 3357 (2020)

Despite a steep increase in dam removal projects, there are few studies on the biophysical responses to dam removal. In this study, we evaluated the short-term (1.5 years) and long-term (5.5 years) effects of partial check dam removal on fish assembl

Basin-scale spatiotemporal distribution of ayu Plecoglossus altivelis and its relationship with water temperature from summer growth to autumn spawning periods

Autor: Shigeya Nagayama, Masanao Sueyoshi, Ryoji Fujii, Morihiro Harada

Publikováno v: Landscape and Ecological Engineering. 19:21-31

As climate warming progresses, it becomes necessary to study the effects of water temperature on the basin-scale dynamic distribution of riverine fish. This study examined the spatiotemporal distribution of Plecoglossus altivelis using the environmen

The role of geology in creating stream climate-change refugia along climate gradients

Autor: Nobuo Ishiyama, Masanao Sueyoshi, García Molinos Jorge, Kenta Iwasaki, N Junjiro Negishi, Itsuro Koizumi, Shigeya Nagayama, Akiko Nagasaka, Yu Nagasaka, Futoshi Nakamura

Identifying climate-change refugia is a key adaptation strategy for reducing global warming impacts. Knowledge of the effects of underlying geology on thermal regime along climate gradients and the ecological responses to the geology-controlled therm

Autumn dispersal and limited success of reproduction of the deepbody bitterling (Acheilognathus longipinnis) in terrestrialized floodplain

Autor: Shigeya Nagayama, Munehiro Oota, Tomohiko Fujita, Jyun-ichi Kitamura, Toshifumi Minamoto, Seiichi Mori, Masayuki Kato, Naofumi Takeyama, Fumiya Takino, Ryuji Yonekura, Hiroki Yamanaka

Publikováno v: Knowledge and Management of Aquatic Ecosystems, Vol 0, Iss 423, p 4 (2022)

The terrestrialization of floodplains has become a concern to river managers and ecologists because it has degraded habitats for floodplain-dependent organisms. We examined the temporal distributions of the endangered deepbody bitterling (Acheilognat
