Soil Invertebrates II: The Diversity of Collembola Associated with Decomposition Bags in 1995 and 1996

Decomposition (litter) bag sampling served as the main focus of our soil arthropod research. The overwhelming numbers of specimens generated from our annual sampling has forced us to streamline our analyses and center on a ubiquitous and ecologically important group of soil arthropods: Collembola or springtails. These small, six-legged arthropods are paramount to the soil […] More »

Residue Decomposition: A Review of the First Four Years of Results

The litter bag study was initiated in 1993 on the Wisconsin Integrated Cropping Systems Trial (WICST). The objectives of this study were to characterize the influence of crop rotation on residue decomposition. In collaboration with the team entomologists, the role of macro- and meso- invertebrates in the decomposition process were also monitored. This latter objective […] More »

Residue Decomposition: A Review of the First Three Years of Results

The litter bag study was initiated in 1993 on WICST. The objectives of this study are to characterize the influence of crop rotation on residue decomposition.  In collaboration with the team Entomologists, the role of macro- and meso-invertebrates in the decomposition process were also monitored.  This latter objective was accomplised using litter bags with different […] 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.

Residue Decomposition and Associated Invertebrates: 1994 Results

The objectives of this study are to characterize the influence of crop rotation on residue decomposition, and to document the role of macro- and meso-invertebrates in the decomposition process. The latter was accomplished using litter bags with different pore sizes to isolate the influence of microorganisms and soil fauna in the decomposition process. Authors: Dave […] More »
