| 内容記述 | In this study, we investigated the geographical distribution and seasonality of Leucocytozoon lovati infection in the Japanese rock ptarmigan (Lagopus mutus japonicus); this bird is one of the special natural monuments of Japan that inhabits the Japanese alpine regions. We examined blood samples from birds captured in the Kubiki, Hida, and Akaishi mountain ranges for three years from 2002 to 2005. Seventy-three blood samples from 42 males, 19 females, and 12 birds of unknown sex were used for this study. The rate of infection with L. lovati was 78.1% in the 73 birds examined. We demonstrated that the L. lovati infection was distributed across wide ranges of ptarmigan populations from the northern to the southern alpine zones. There was no sex bias in the prevalence ratio. The prevalence of L. lovati and the level of parasitization of the blood cells tended to increase from spring through summer; in contrast, a decrease was observed from summer through autumn. Although L. lovati infection was observed in a number of local populations inhabiting three mountainous regions, no infected birds were found in Mt. Johnen-dake and Mt. Maejohnen-dake. It is necessary to continue surveying the relationship between the population dynamics of the ptarmigan and the density of the arthropod vector from the perspective of in situ conservation of this endangered species. | |||||
