Re-connecting the ecological network in the ditches of modernization of paddy field for the oriental weatherloach (Misgurnus anguillicaudatus) on Sado island

在佐渡岛国中地区的52条现代化沟渠中调查了东方泥鳅的分布及其相关环境因子。利用GIS、GLM和AIC分析结果表明，影响泥鳅密度的正因子在不同季节存在差异。我们还制作了一张GIS地图，预测了Kuninaka地区所有沟渠中泥鳅的密度。讨论了潜势分布图在东方天气鳅管理中的应用。

The distribution of the oriental weatherloach, Misgurnus anguillicaudatus, together with related environmental factors were surveyed at 52 ditches of modernization in the Kuninaka region on Sado island. Analysis with GIS, GLM and AIC revealed that positive factors for the loach density were differed from each season. We also produced a GIS map that the predicted the density of loach across all ditches within the Kuninaka region. We discuss how the potential distribution map can be applied to the management of the oriental weathetloach.
