Landscape context not patch size determines bumble-bee density on flower mixtures sown for agri-environment schemesM S Heard
NERC Centre for Ecology and Hydrology, Monks Wood, Huntingdon PE28 2LS, UK
Biol Lett 3:638-41. 2007..Importantly, the relative response to sown forage patches varied widely across a landscape gradient such that their impact in terms of attracting foraging bumble-bees was greatest where the proportion of arable land was highest...- Weeds in fields with contrasting conventional and genetically modified herbicide-tolerant crops. I. Effects on abundance and diversityM S Heard
NERC Centre for Ecology and Hydrology, Monks Wood, Abbots Ripton, Huntingdon, Cambridgeshire PE28 2LS, UK
Philos Trans R Soc Lond B Biol Sci 358:1819-32. 2003..In all three crops, weed diversity was little affected by the treatment, except for transient effects immediately following herbicide application... - Weeds in fields with contrasting conventional and genetically modified herbicide-tolerant crops. II. Effects on individual speciesM S Heard
NERC Centre for Ecology and Hydrology, Monks Wood, Abbots Ripton, Huntingdon, Cambridgeshire PE28 2LS, UK
Philos Trans R Soc Lond B Biol Sci 358:1833-46. 2003..These differences compounded over time would result in large decreases in population densities of arable weeds. In maize, populations may increase... - Invertebrates and vegetation of field margins adjacent to crops subject to contrasting herbicide regimes in the Farm Scale Evaluations of genetically modified herbicide-tolerant cropsD B Roy
NERC Centre for Ecology and Hydrology, Monks Wood, Abbots Ripton, Huntingdon, Cambridgeshire PE28 2LS, UK
Philos Trans R Soc Lond B Biol Sci 358:1879-98. 2003..Scorching of vegetation by herbicide-spray drift was on average 1.6% on verges beside conventional crops and 3.7% beside GMHT crops, the difference being significant for all three crops... - Effects of genetically modified herbicide-tolerant cropping systems on weed seedbanks in two years of following cropsL G Firbank
Centre for Ecology and Hydrology, Lancaster Environment Centre, Library Avenue, Bailrigg, Lancaster LA1 4AP, UK
Biol Lett 2:140-3. 2006..These new data provide important empirical evidence for longer-term effects of GMHT cropping on farmland biodiversity... - Invertebrate responses to the management of genetically modified herbicide-tolerant and conventional spring crops. I. Soil-surface-active invertebratesD R Brooks
Rothamsted Research, Harpenden, Hertfordshire AL5 2JQ, UK
Philos Trans R Soc Lond B Biol Sci 358:1847-62. 2003..Counts of carabids that feed on weed seeds were smaller in GMHT beet and spring oilseed rape but larger in GMHT maize. In contrast, collembolan detritivore counts were significantly larger under GMHT crop management... - Invertebrate responses to the management of genetically modified herbicide-tolerant and conventional spring crops. II. Within-field epigeal and aerial arthropodsA J Haughton
Rothamsted Research, Harpenden, Hertfordshire AL5 2JQ, UK
Philos Trans R Soc Lond B Biol Sci 358:1863-77. 2003..These species, and the detritivore Collembola, may be useful indicator species for future studies of GMHT management... - Crop management and agronomic context of the Farm Scale Evaluations of genetically modified herbicide-tolerant cropsG T Champion
Broom s Barn Research Station, Higham, Bury St Edmunds, Suffolk IP28 6NP, UK
Philos Trans R Soc Lond B Biol Sci 358:1801-18. 2003..The audit of inputs found no evidence of bias... - Responses of plants and invertebrate trophic groups to contrasting herbicide regimes in the Farm Scale Evaluations of genetically modified herbicide-tolerant cropsC Hawes
Scottish Crop Research Institute, Invergowrie, Dundee DD2 5DA, UK
Philos Trans R Soc Lond B Biol Sci 358:1899-913. 2003.... 
Ban on triazine herbicides likely to reduce but not negate relative benefits of GMHT maize croppingJ N Perry
Rothamsted Research, Harpenden, Hertfordshire AL5 2JQ, UK
Nature 428:313-6. 2004..Our overall conclusion is that the comparative benefits for arable biodiversity of GMHT maize cropping would be reduced, but not eliminated, by the withdrawal of triazines from conventional maize cropping...- Determinants of species richness in the Park Grass ExperimentM J Crawley
Department of Biological Sciences, Imperial College London, Silwood Park, Ascot, Berkshire, SL5 7PY, United Kingdom
Am Nat 165:179-92. 2005..The analysis demonstrates how multiple factors contribute to the observed diversity patterns and how environmental regulation of species pools can operate at the same spatial and temporal scale as biomass effects... - On the rationale and interpretation of the Farm Scale Evaluations of genetically modified herbicide-tolerant cropsG R Squire
Scottish Crop Research Institute, Invergowrie, Dundee DD2 5DA, UK
Philos Trans R Soc Lond B Biol Sci 358:1779-99. 2003..The analysis leads to a summary of factors that were, and were not, examined in the first 3 years of the study and points to where modelling can be used to extrapolate the effects to the landscape and the agricultural region...
