Soil Invertebrates I: The Diversity of Collembola Associated with 1997 Soil Core Samples

Soil core sampling was initiated in 1995 to complement pitfall traps and decomposition bags used to survey the abundance and diversity of arthropods occurring in selected WICST plots. The soil cores allow us direct comparison of results with other investigators in the NRI Soil Biodiversity Team. Also, because soil core samples are independent [...] More »

Soil Invertebrates Associated with 1996 Soil Core Sampling and Residue Decomposition

Soil core sampling began in 1995 as a complementary measure of soil arthropod abundance and biological diversity. The objectives of the soil core study are (1) to determine the influence of crop rotation, fertilizer and pesticide/herbicide inputs on soil arthropod populations, and (2) to have a sampling plan which is directly comparable to the [...] More »

Soil Invertebrates associated with Soil Core Sampling and Residue Decomposition, 1995

Soil core sampling was initiated in 1995 to complement both the litter bag and pitfall trap sampling studies that have been ongoing in the WICST plots. The objective of the soil core study is to determine the influence of crop rotation, fertilizer inputs, and pesticide/herbicide inputs on soil arthropod populations…more Authors: E.J. Rebek, D.B. Hogg, and [...] More »

Pitfall Trap Analysis of Soil Macroathropods associated with WICST - 1994

Our hypothesis in this study of arthropod diversity continues to be that¬† the level and frequency of soil disturbance (both physical and chemical) in the various cropping systems influence the numbers and kinds of arthropods inhabiting the plots.¬† Differences in arthropod populations could contribute to as well as result from changes in soil characteristics. In [...] More »

Pitfall Trap Analysis of Soil Macroarthropods Associated with the Wisconsin Integrated Cropping Systems Trial, 1993

The Wisconsin Integrated Cropping Systems Trial has become a forum for examining the ecological ramifications, both short and long term, of different approaches to farming and philosophies of land stewardship. Like several other research groups, we have focused on the soil biota as one measure of environmental impacts of agriculture. Our operational hypothesis for our [...] More »
