• Transgenic Bt plants decompose less in soil than non-Bt plants (2005, background): “These results differed from those reported by Hopkins and Gregorich (2003), who found no difference in the”
• Can Bacillus thuringiensis (Bt) corn residues and Bt-corn plants affect life-history traits in the earthworm Aporrectodea caliginosa? (2006, background): “Most studies show that Bt-protein is degraded or inactivated in soil within weeks (Head et al., 2002; Hopkins and Gregorich, 2003 ).”
• A Comparison of Soil Microbial Community Structure, Protozoa and Nematodes in Field Plots of Conventional and Genetically Modified Maize Expressing the Bacillus thuringiens is CryIAb Toxin (2005, background): “Measurements from a field site after four years continuous Bt-maize revealed trace amounts of Bt toxin (<0.1 ng g)1) in whole soil samples but higher concentrations (upto 4.4 ng g)1) associated with decomposing maize residues (CryIA; Hopkins and Gregorich, 2003).”
• Assessing changes in soil microbial communities and carbon mineralization in Bt and non-Bt corn residue-amended soils (2007, result): “Finally, residue type (Bt and non-Bt) did not significantly affect cumulative CO2 released, which was similar to previous research reporting that rates of soil CO2 evolution were not affected by corn residue type (Hopkins and Gregorich, 2003).”
• Field decomposition of transgenic Bt maize residue and the impact on non-target soil invertebrates (2007, background): “slowly than non-Bt maize (Hopkins and Gregorich 2003; Castaldini et al. 2005; Flores et al. 2005; Raubuch et al. 2007).”
• Detectability of Coleopteran-specific Cry3Bb1 Protein in Soil and Its Effect on Nontarget Surface and Below-Ground Arthropods (2005, background): “Hopkins and Gregorich (2003) suggested that much of the protein in crop residues quickly decomposes in soil, but that a small fraction may be protected from decay in relatively recalcitrant residues.”
