[Press Release] The house shrews’ intraspecific phylogeny suggesting a history of human activities

The house shrews, Suncus murinus-S. montanus species complex, are tiny mammals that often live in a human’s house, and thus their distributions are considered to be closely associated with a history of human activities. An international team of eight countries’ researchers that include Assist. Prof. Satoshi D. Ohdachi and Prof. Hitoshi Suzuki (Division of Biosphere Science) analyzed a mitochondrial DNA region of the house shrews captured from east African coasts to Japan, and revealed the shrews’ intraspecific phylogeny. Results from a phylogenetic tree suggest that the present distribution of the house shrews is due to past human activities such as migration and economic exchange. This research outcome is published in Mammal Study, an academic journal of the Mammal Society of Japan.

[Press Release] Winter aggregation of nonnative rainbow trout in small tributaries: implications for effective control

A research team of Assoc. Prof. Itsuro Koizumi and his graduate students (Division of Biosphere Science) revealed that rainbow trout, one of “100 of the World's Worst Invasive Alien Species”, immigrated to and extremely aggregated in small tributaries of the Otofuke River, central Hokkaido during the winter. This study has an important implication for effective control of this invasive fish and helps to understand a mechanism of adaptation to a new environment. This research outcome is published in Ichthyological Research, an academic journal of the Ichthyological Society of Japan.

[Press Release] Revealing activity patterns of representative mammals of Hokkaido by infrared cameras

A research team that includes a JSPS Research Fellow Takashi Ikeda, currently a research officer at National Institute for Land and Infrastructure Management, Assoc. Prof. Itsuro Koizumi, and a Ph.D. student Kenta Uchida (Division of Biosphere Science) revealed seasonal and diel activity patterns of representative mammals of Hokkaido such as brown bear, Ezo sika deer, Ezo red fox, and Eurasian red squirrel by using a huge amount of photographic data (total 13,279 photos!) taken by infrared cameras. This study provides a fundamental knowledge of these mammals’ ecologies and has an important implication for wildlife management.

This research outcome is published as a research article of an open-access scientific journal, PLoS One.
