| Research Abstract |
Abundance of three frog species(Rana porosa porosa, R. japonica, and Rhacophorus schlegelii) was investigated in the middle Sakura River basin, Ibaraki, Japan. The investigation suggested that some artificial factors including implementation of land improvement project as well as natural factors would affect frog abundance. Based on the investigation, the simulation model to predict frog inhabitation and to build their potential maps was constructed. A population dynamics model for R. japonica was also developed, and the model calculated impact of constructing concrete agricultural canals on its population and effectiveness of installation of eco-friendly countermeasures in the concrete canals.
