| Notes on the effect of an artificial landscape change on the home range of a female Tsushima leopard cat, _Prionailurus bengalensis euptilurus_ in the Tsushima Islands, Japan | |
| 2014 Mammal Study (39): 47-52 | |
The Tsushima leopard cat, _Prionailurus bengalensis euptilurus_, is a subspecies of the leopard cat, Prionailurus bengalensis, and it is an insular population on the Tsushima Islands in Japan. This subspecies is listed as Critically Endangered (CR) on the Japanese Red List, as declared by the Ministry of the Environment in 2012, due to its decreasing population size. The population of Tsushima leopard cats was estimated to contain approximately 300 individuals during the 1970s. However, the Japanese Ministry of the Environment has estimated that only approximately 100 individuals remained in the 2010s. The loss of suitable habitat and traffic accidents are the principal causes of the population decline for the Tsushima leopard cat. In addition, domestic cats may have a negative impact on the Tsushima leopard cat due to competition for prey and disease transmission. Predation by dogs may also be a negative influence. Among these detrimental factors, habitat deterioration has the most severe direct and indirect impacts on the survival and ecology of the Tsushima leopard cat. Road and building construction, agricultural land-redevelopment, and deforestation by logging have degraded and fragmented the populations of the Tsushima leopard cat. To determine the present status and ecology of the Tsushima leopard cat and to develop effective conservation plans, it is necessary to understand the effects of human activities on the ecology of the Tsushima leopard cat. The Tanohama area is a region of stable habitat for the Tsushima leopard cat and has maintained a high density of this. However, a land redevelopment project in this area was conducted in 2006 by local government of Tsushima city. The present study assesses the effects of this agricultural land redevelopment on the home range and spatial-use patterns of a female Tsushima leopard cat in the Tanohama area. |
