WenJun Zhang Computational Ecology and Software ISSN 2220-721X 2011 1(3) 183-185 09/2011 International Academy of Ecology and Environmental Sciences community structure non-parametric test comparison arthropods Java program The Java algorithm to statistically compare structure difference of two communities was presented in this study. Euclidean distance, Manhattan distance, Pearson correlation, Point correlation, quadratic correlation and Jaccard coefficient were included in the algorithm. The algorithm was used to compare rice arthropod communities in Pearl River Delta, China, and the results showed that the family composition of arthropods for Guangzhou, Zhongshan, Zhuhai, and Dongguan are not significantly different.
