Ballooning dispersal using silk: world fauna, phylogenies, genetics and models.
It is contended that ballooning behaviour in all three orders can be described as a mixed Evolutionary Stable Strategy, which comprises individual bet-hedging due to habitat unpredictability, giving an underlying randomness to individual ballooning, with adjustments to the individual Ballooning probability being conferred by more predictable habitat changes or colonization strategies.

A novel, integrated approach to assessing social, economic and environmental implications of changing rural land-use: A case study of perennial biomass crops
Summary 1. Concern about climate change and energy security is stimulating land-use change, which in turn precipitates social, economic and environmental responses. It is predicted that within 20Expand
Responses of plants and invertebrate trophic groups to contrasting herbicide regimes in the Farm Scale Evaluations of genetically modified herbicide-tolerant crops.
The Farm Scale Evaluations have demonstrated over 3 years and throughout the UK that herbivores, detritivores and many of their predators and parasitoids in arable systems are sensitive to the changes in weed communities that result from the introduction of new herbicide regimes. Expand
Spatial dynamics of predation by carabid beetles on slugs
Parametric analysis revealed that changes in the large slug class, at each sampling point between June and July (growth), were negatively related to the local numbers of slug-positive beetles, and that growth declined as the local number of beetles increased. Expand
Mesocosm Experiments as a Tool for Ecological Climate-Change Research
A new database of over 250 post-1990 studies that have explored different components of climate change across a range of organisational levels, scales, and habitats is constructed and issues related to realism, reproducibility and control are assessed. Expand
Entomopathogenic Nematodes: Biodiversity, Geographical Distribution and the Convention on Biological Diversity
This paper addresses three major issues: molecular taxonomy and its application to elucidate the biodiversity and biogeography of entomopathogenic nematodes, and a brief consideration of the Convention on Biological Diversity and its implications for future work with entomopathic nematode and biological control.

Weed seed choice by carabid beetles (Coleoptera: Carabidae): Linking field measurements with laboratory diet assessments
Carabid beetles could potentially provide a number of ecosystem services in arable fields, including the regulation of weeds by eating seeds. Spatio-temporal variability in the incidence of predationExpand
An introduction to the Farm‐Scale Evaluations of genetically modified herbicide‐tolerant crops
1. Several genetically modified herbicide-tolerant (GMHT) crops have cleared most of the regulatory hurdles required for commercial growing in the United Kingdom. However, concerns have beenExpand
National-scale regulation of the weed seedbank by carabid predators
This work shows that carabid seed predators have regulatory effects on the seedbank that appear general and robust across a range of current cropping and farm management situations at the national scale. Expand
Invertebrate responses to the management of genetically modified herbicide-tolerant and conventional spring crops. II. Within-field epigeal and aerial arthropods.
The effects of the management of genetically modified herbicide-tolerant (GMHT) crops on the abundances of aerial and epigeal arthropods were assessed in 66 beet, 68 maize and 67 spring oilseed rapeExpand
