Notre Dame. Indiana Patterns of Coleoptera Species Diversity in Contrasting

ABSTRACT: The pattern of Coleoptera species diversity in coppice hardwoods and white pine canopy communities was investigated. The information-theory index H(s) and the index D were used to measure diversity. The distribution of individuals within species was measured by using redundancy and evenness indices. Diversity in the coppice was greater than in the white pine. The coppice canopy community followed a seasonal trend in diversity, even-ness and redundancy. Diversity in the white pine community did not follow an apparent seasonal trend. Considerably fewer species and indi-viduals occurred in the white pine, which tended to magnify the impor-tance of the appearance and disappearance of dominant species and thereby to obliterate any seasonal trend in diversity, redundancy and evenness
