Research teams from the National Institute for Environmental Studies and Toho University have released data on the frog habitat in and around the evacuation order area in Fukushima Prefecture due to the accident at the Fukushima Daiichi Nuclear Power Station of Tokyo Electric Power Company.Eight species such as Japanese tree frogs have been confirmed to inhabit, and distribution data are visualized for three of them.
According to the National Institute for Environmental Studies, the research team was attended by Akira Yoshioka, a senior researcher at the Fukushima branch of the institute, Keita Fukasawa, a senior researcher at the Biological and Ecosystem Environmental Research Center, and Noeda Yasushima, a postdoctoral fellow at the Faculty of Science, Toho University.
Many paddy fields were lost in the evacuation order area due to the evacuation of residents.The research team installed recording devices in the evacuation order area and 52 public land sites around it from mid-May to mid-July every year to investigate how this affected the frogs that live in paddy fields. , The male gathered the barks calling the female.
When the audio collected in 2014 and 2015 was confirmed, a total of eight species of Japanese tree frog, Schlegel tree frog, Daruma frog, bullfrog, Japanese wrinkled frog, Moria frog, Tago's brown frog, and Kajika frog were confirmed to inhabit.Of these, we created visualized distribution data for the three species of Japanese tree frog, Schlegel tree frog, and Daruma frog, which had a large amount of recorded data.
Japanese tree frogs and Schlegel tree frogs appear in more than half of the evacuation order areas where there are no paddy fields, but Daruma frogs, which are considered to be highly dependent on paddy fields, appear in a limited number of places.
