We tracked the behavior of a weasel for about a month, using an automated wild animal tracking system that assimilates data from radio-tracked animals. The results showed that the home range of the weasel was about 25 ha, and we identified the spatial habitat preferences of the weasel, which mainly utilized open areas (i.e., fields and gardens) and avoided areas of high-density vegetation. Furthermore, we reconstructed flooding conditions by using a 2D hydro-simulation, and analyzed the relationships among floods, vegetation communities, and wild mammal behavior. The results showed that there was a strong connection among flooding, vegetation community structure, and animal habitat use. These results present a new and important insight into river ecosystem conservation. |
