The description of stream bottom communities, an important part of most ecological studies, requires extensive calculations before analysis or use. A COMPUTER PROGRAM WAS DEVELOPED TO GENERATE SEVERAL OF THE COMMUNITY DESCRIPTIONS SOMETIMES REFERRED TO COLLECTIVELY AS 'DIVERSITY INDICES'. The program was designed specifically for a study of benthic macroinvertebrates in a polluted river, but the indices can be used in the study of many types of communities. Diverse is designed to run on a medium to large computer which accepts Fortran IV and allows up to 13,000 bits of storage and has either a drum, disc, or scratch tape storage unit. The program accepts a maximum of 99 different species. (Author)
