Effects on Ecosystem
(2021)
QHow have ecosystems changed in evacuation-order zones?
AWe have been monitoring various organisms such as mammals, birds, frogs, and insects since 2014. The data obtained for mammals and birds are publicly available on a website, which is routinely updated.
The monitoring data for mammals and birds are publicly available to researchers in the form of published papers, which is updated from time to time. Distribution maps are also available for easy browsing at the National Institute for Environmental Studies (NIES) websites: BioWM and KIKI-TORI Map.
This study is conducted by trapping insects within and outside the evacuation-order zones (also in zones where the evacuation order has been canceled).
We have been using statistical modeling to determine whether the data obtained for this study reflects the influence of the evacuation order or is simply coincidental.
The number of individuals of almost all species of polliniferous insects collected in 2014, with the exception of the carpenter bee, was not significantly small in the evacuation-order zones.
Following mammals and birds, data for frogs was released in 2020 in data paper format.
