• Cooper, Idelle A., Elizabeth Roeder, and Jonathan M. Brown. 2003. Arthropod response to burning and mowing in a reconstructed prairie. Biology.[pitfall
    traps, vegetation sweeping, and Berlese extraction methods, measured
    soil temperature and sampled above- and belowground arthropods 1 and 2
    weeks after mowing on 10 regularly-burned 10-m x 10-m plots; identified
    variation in responses of 16 insect taxa; lower abundance in many
    aboveground taxa but no change in underground taxa was found due to
    mowing, greater abundance of aboveground taxa and lower number of
    belowground taxa were found due to burning]
  • Janson, Tor. 1999. A restoration benchmark: assessment of CERA's Lepidoptera and comparison to other prairies. Prairie Studies Independent Research, Prof. Jackie Brown and Prof. Liz Queathem.[voucher
    specimens collected; Pollard method of butterfly transect counts; 4
    transect routes, 180-m each, censused once a week in June, July, and
    August, walking time 9-11.5 minutes; routes located in Lab Prairie,
    Perley Prairie, South Slope Savanna, and Wilson Prairie; similar routes
    at Reichelt and Krumm, different method at Broken Kettle Grasslands in
    the Loess Hills; calculated Simpson's Diversity index, Coeffecient of
    Community to measure similarity of nectar sources and butterfly
    populations; 36 species observed at CERA, 9 prairie spp, 7 of
    conservation concern; site was only factor significantly affecting spp
    richness, abundance, and diversity; evaluated nectar sources, compiled
    list of hostplants for spp of potential conservation concern]
  • Dubach, Brent. 1968. Fluctuations in populations of Collembola in the Conard Environmental Research Area. Independent Project.[collected
    core samples (6 inches deep, 24 total) from four plots (30 yards square
    area), measured abundance of Collembola species, temperature, and water
    content in each core; range of mean temperature readings (°F) = 34-86º,
    average water content = 37.7% - 34.4% across plots; each core density =
    200cc., volume per sample = 600cc., total volume for entire study =
    14400cc; 1062 total Collembola collected, average Collembola
    density=7.38x104 per cubic meter; 22 species identified, Orchesella
    sinsliei most abundant species in study (17.1% of total Collembola),
    total of 186 specimens recorded, Onychiurus subtenuis and Pseudosinella
    violenta also abundant; data available: distribution of Collembola
    species over plots, physical factors: water content and soil moisture]
  • Breed, Mike. 1972. A comparative study of insect communities at Conard Environmental Research Area. Independent Project, Prof. Ken Christiansen.[Sweep
    net, light trap, and pitfall jars; collected in prairie, oak-hickory
    forest, and "old field" habitats; contains data on 98 insect families
    for each September 1972 collection date; also some data on larvae, but
    identified only to order, not family; breakdown of families by niche,
    plant feeding group, and habitat; concludes that forest is most diverse
    area]
