Modelling of Population Migration to Reproduce Rank-Size Distribution of Cities in Japan

From our previous data analysis of the census data after World War II, it has been clarified that the power exponent of the rank-size distribution of cities changes with time and Zipf’s law holds only for a restricted period. We show that Zipf’s law broke down owing to the great mergers and re...

متن کاملMigration Prediction and Monitoring of Rice Planthoppers in Japan
This paper presents a new method of migration prediction for rice planthoppers. Using this new method, a three-dimensional backward trajectory analysis was conducted to find migration sources of rice planthoppers that immigrated into Japan. The results showed that the coastal regions of Fujian province in China and Taiwan were possible sources of the whitebacked planthopper (WBPH) that immigrat...

To test this hypothesis, individuals of each developmental stage of diamondback moth were reared at 1 5 ° C in the laboratory and kept at 0°C for varying periods of time an...
