| 内容記述 | This study examined the relationship between population densities of hazel grouses (Tetrastes bonasia) and the predators in Nishiokkoppe, Hokkaido, Japan. We set up a total of 21 infrared-triggered cameras and carried out a call count method at forest roads from June 2015 to October 2015. As a result of our camera study, 83 pictures of hazel grouses, 687 pictures of Hokkaido red foxes ( Vulpes vulpes schrencki) and 439 pictures of Hokkaido raccoon dogs (Nyctereutes procyonides albus) were taken. There were no significant relationships between call count or photography frequencies of hazel grouses and photography frequencies of Ezo red foxes and Ezo raccoon dogs. However, photography frequencies of hazel grouses and rates of coniferous-deciduous mixed forests positively correlated (rs = 0.873494, P=0.004593, Spearman's rank method). The results suggested that hazel grouses avoided habitats selected by Hokkaido red foxes and Hokkaido raccoon dogs. | |||||||
