Butterfly community composition and conservation in and around a primary woodland of Mount Fuji, central Japan

摘要: A study was conducted in and around the Aokigahara primary woodland of Mount Fuji, central Japan, to clarify butterfly community structure along environmental gradients human disturbance, shade, plant species richness, with a view formulating conservation strategies for community. The composition abundance were recorded during 1999 transects three habitats: woodland, edge open land. Two sites selected each habitat. Canonical correspondence analysis (CCA) showed that correlated both disturbance shade. However, neither relationship significant when shade analyzed as covariables (partial CCA), suggesting combined effect two variables played an important role determining structure. In contrast, CCA no relationships between or hostplant richness. Correlation analyses characteristics scores occurring more disturbed habitats voltine, had wider range associated lower tolerance than those less habitats, darker higher tolerance. Generally, could be understood well terms habitat templet theory. To conserve endangered on Red List maintain diversity this suggests need not only area, but most importantly surrounding forest including areas semi-natural grassland.
