　View Summary

The Japanese National Biodiversity Strategy 2010 calls for the creation of ecological networks as a biodiversity conservation policy. However, there is an obvious lack of information on the spatial distribution of many species and a lack of scientific methods for examining habitat requirements to establish the need for constructing these networks for target species. This study presents a quantitative method for assessing the need for ecological networks through modeling the potential geographic distributions of species based on a case study of local populations of Asiatic black bear (Ursus thibetanus japonicus) in Fuji and Tanzawa, Japan. A total of 1541 point records of occurrences of Asiatic black bears and 11 potential predictors were analyzed in a GIS environment. After a predictive distributional map was obtained using the Maximum Entropy (MaxEnt) algorithm, a gap analysis was carried out and population size was estimated. Approximately 24% of the bear's predicted habitat area fell within a wildlife protection area, 2% within a nature reserve, and 37% within natural parks. Conservation forest comprised 54% of the total area of predicted habitat; of this, national forest comprised 2%, and private and communal forest comprised 37%. The total estimated Asiatic black bear population in this region was 242, with 179 individuals in the Fuji local population, 26 in the Tanzawa local population, and 37 in the corridor patch between the two local populations. Our study also found a potential corridor connecting the Fuji and Tanzawa local populations, as well as potential habitat corridors in the Fuji region containing subpopulations on Mt. Fuji (119 individuals) and Mt. Kenashi (53 individuals). An additional subpopulation on Mt. Ashitaka (7 individuals) is isolated and not fully protected by a zoning plan. Mt. Furo's subpopulation is considered to be almost extinct, although black bears were observed here until 2002 based on the report by Mochizuki et al. (2005). The total black bear population of the Fuji-Tanzawa region is considered to be "endangered"; thus, an adequate population size might be difficult to maintain even if this region were to be internally connected by means of an ecological network.

Applicability of a predictive distributional model for the distribution of the Asiatic black bear (<i>Ursus thibetanus japonicus</i>) to a local population in the Tanzawa region of Japan

　View Summary

A predictive distributional model of Asiatic black bears (<i>Ursus thibetanus japonicus</i>) is useful for the effective management of the species' habitat. Applicability of a previously developed model to the Tanzawa local bear population was examined. Three different types of animal presence data were collected for validation of the model. The overall rate of correct classification was 67%?85%, indicating that the model can be extrapolated to other local populations with acceptable transferability. Accuracy of the model's predictions differed depending on the data sampling design most likely as a result of bias in one of the sampling methods. The model tended to underestimate the actual presence of bears. We attribute this underestimation to 1) properties of the particular habitat used by the local Tanzawa population and 2) the model's greater ability to predict the habitat of mountain bears than that of Satoyama bears.

　View Summary

A study was conducted on Orthoptera (Acrididae, Tettigoniidae, Gryllidae) in 56 sites of reclaimed land of Kanazawa District, Yokohama City, Kanagawa Prefecture through May to October of 2008. 28 species and 1941 individuals were recorded during this study. By using TWINSPAN and partitioning, classifications of the Orthoptera and study sites were made based on the results of this study. Also we investigated concerning vegetation, soil, distance from original land,and area coverd with vagetation around field as environmental factors. The study sites were sorted into 5 groups and the Orthoptera were sorted into 4 groups by using TWINSPAN. Based on 5 study site groups, partitioning analysis was conducted.Results suggest vegetation height, coverings of evergreens and deciduous trees of middle to high height, and distance from original land are related to Orthoptera inhabitation. However, it has not been clearly understood the distance from original land was selected as explanatory variable. A further verification is necessary because of the possibility that area coverd with vegetation around the field is related was suggested.
