A Computer Program for the Analysis of Macroinvertebrate Data from Water Quality Surveys.

摘要

An original DICALC program has been revised to calculate species diversity (using three methods) and relative abundance, absolute abundance, and density of each species collected at a sampling station. The new program has greater flexibility and utility for examining differences between aquatic community samples than the original DICALC. The procedures and options for DICALC are explained and the program is given in the appendix. (Author)
