Abstract

Associations among nematode communities were studied in 18 Indiana mixed-hardwood stands of varying composition, soils, physiography, and past management practices. All sites were sampled in April, July, and October of 1968 and 1969. A total of 175 species representing eight orders were found, with 18 species occurring in all 18 sites, and approximately half the total species occurring in more than 50% of the sites. Taxonomic similarity, based on nematode species composition, was determined for the woodlots by means of a resemblance equation. Woodlots containing similar nematode species also showed similarities in dominant tree species and in soil types. Sites that had undergone major disturbances were the most dissimilar. Key words: Indiana hardwood stands, resemblance equation.
