The drive to squeeze ever more food from the land has sent Europe's farmland wildlife into a precipitous decline. How can agricultural policy be reformed so that we have fewer grain mountains and more skylarks? 
Farmers' Interest in Nature and Its Relation to Biodiversity in Arable Fields
Biodiversity declines in farmland have been attributed to intensification of farming at the field level and loss of heterogeneity at the landscape level. However, farmers are not solely optimizing ...
Managing Farming's Footprint on Biodiversity
A simple risk-assessment model that predicts the effect of environmental change on farmland biodiversity may be more generally applicable to analyzing the effects of environmental changes on
Biological control as an ecosystem service: partitioning contributions of nature and human inputs to yield
1. The concept of ecosystem services (ES) has rapidly entered policy and planning agendas nationally and globally. However, its usefulness is hampered by, for example, insufficient understanding of
Agriculture: Widespread local house-sparrow extinctions
This work uses a combination of field experimentation, genetic analysis and demographic data to show that a reduction in winter food supply caused by agricultural intensification is probably the principal explanation for the widespread local extinctions of rural house-sparrow populations in southern England.
The role of grassland sward islets in the distribution of arthropods in cattle pastures
It is well documented that cattle reduce their grazing activity in the vicinity of cattle dung, which gives rise to distinct patches, or islets as they have been termed, of longer sward that have an influence on grassland biodiversity.
Human land use, agriculture, pesticides and losses of imperiled species
Aim  Anthropogenic habitat loss is usually cited as the most important cause of recent species’ extinctions. We ask whether species losses are in fact more closely related to habitat loss than to any
Assessing the risks associated with new agricultural practices
Assessment of environmental impacts of future land-use change in a much broader context is proposed, based on principles applied to assess genetically modified crops for one part of agriculture.
Linking agricultural practice to insect and bird populations: a historical study over three decades
Data from a broad suite of species provide support for linked temporal change between farmland birds, invertebrate numbers and agricultural practice in Scotland, and are consistent with the view that agricultural change has influenced birds through changes in food quality or quantity.
