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 of arthropod […] More »

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 »

Analysis of Soil Macroarthropods Associated with Pitfall Traps in the Wisconsin Integrated Cropping Systems Trial, 1995

The health of soil ecosystems is often quantified using biological diversity indices to gain insight into the “stability” of these systems. In general, a greater diversity of soil fauna inhabiting a system help establish healthy soils because the interactions of a richer complex of taxa (e.g. species) contributes to a more stable food web. Macroarthropods […] 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 »

A Survey of Soil Macroarthropods associated with Corn in Alternative Cropping Systems – 1992

WICST provides a unique laboratory for examining the ecological ramifications, both short and long term, of different approaches to farming and philosophies of land stewardship. Much of the ecological ‘action’ will take place in and on the soil, and will be related to the health of the soil as measured in chemical, physical, and biological […] More »
