Journal ArticleDOI
The environmental consequences of adopting conservation tillage in Europe: reviewing the evidence
TL;DR: Under conservation tillage, a richer soil biota develops that can improve nutrient recycling and this may also help combat crop pests and diseases, and the greater availability of crop residues and weed seeds improves food supplies for insects, birds and small mammals.
Journal ArticleDOI
Red–blue plots for detecting clusters in count data
TL;DR: A new index and four new graphical displays, termed "red-blue" plots, are presented to study and measure clustering in spatially referenced count data to facilitate a comprehensive definition of the size and dimension of a cluster.
Journal ArticleDOI

TL;DR: In this paper, a quantitative synthesis with data collected from several cropping systems in Europe and North America, analyzed how the level and within-field spatial stability of natural pest control services was related to the simplification of the surrounding landscape.
Journal ArticleDOI
The Effects of Agricultural Practices on Carabidae in Temperate Agroecosystems
John M. Holland,M. L. Luff +1 more
TL;DR: Comparisons of conventional and organic farming systems suggest that localised short-term variations in species’ abundances are more important than the overall farming system used, and further measures need to be taken if Carabidae are to realise their potential in integrated pest management systems.
Journal ArticleDOI
Influence of beetle banks on cereal aphid predation in winter wheat
TL;DR: The results are discussed in terms of the peak activity periods of the different predatory groups and the consequences for integrated crop management (ICM).
