• McDonald, Tami. 1994. Genetic diversity within and between populations of Indiangrass (Sorghastrum nutans) in Iowa tallgrass prairie remnants.
    Advanced Population Biology, Stephen Trumbo. [Cellulose acetate
    electrophoresis for allozymes of 3 enzymes (PGI, PGM, and ME) of S.
    nutans populations from CERA, Reichelt, Turner Station, and the Skunk
    River Prairie Remnant (20 individuals at each location); determined
    allele/genotype frequencies, inbreeding coefficients, genetic identity,
    and genetic diversity (expected heterozygosity); populations
    significantly inbred and significantly less heterozygous than expected;
    populations were also genetically similar, and nearly identical at the
    three loci]
  • Jackson, Andrea. 1994. Genetic diversity of Aster laevis at the Conard Environmental Research Area.
    Stephen Trumbo. [Cellulose acetate electrophoresis for allozymes of 3
    enzymes (PGI and PGM) of 49 individuals from 8 subpopulations of A.
    laevis at CERA; determined observed and expected heterozygosity, number
    of alleles, proportion of polymorphic alleles, inbreeding coefficient,
    and genetic structure; observed and expected heterozygosity mostly
    nonsignificant; for population as a whole, variation, proportion of
    polymorphic loci, and number of alleles per loci are high;
    heterozygosity lower than expected; most subpopulations not inbred]
