House-sparrow populations have declined sharply in Western Europe in recent decades, but the reasons for this decline have yet to be identified, despite intense public interest in the matter. Here we use 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… 

Urbanization, nestling growth and reproductive success in a moderately declining house sparrow population

The reproductive success of urban and rural sparrows in a central European country, Hungary is investigated, finding that rural pairs produced more and larger fledglings than suburban pairs, and the difference remained consistent in two years with very contrasting meteorological conditions during breeding.

Size and trends of the House Sparrow Passer domesticus population in Great Britain

House Sparrow Passer domesticus populations have declined throughout Europe over the last two to three decades; this is of particular concern in urban areas. We analysed data from extensive census

The House Sparrow Passer domesticus in urban areas: reviewing a possible link between post-decline distribution and human socioeconomic status

The House Sparrow Passer domesticus is traditionally associated with human habitation. However, the species has undergone dramatic declines in many urban areas in north-western Europe. There are many

Low genetic differentiation in a sedentary bird: house sparrow population genetics in a contiguous landscape

The genetic diversity and differentiation of the house sparrow populations across Finland in the 1980s are studied, at the onset of the species' decline in abundance, to provide a benchmark for conservation biologists and emphasize the influence of landscape structure on gene flow.

The recent declines of farmland bird populations in britain : An appraisal of causal factors and conservation actions

In this paper, the main aspects of agricultural intensification that have led to population declines in farmland birds over the past 50 years are reviewed, together with the current state of

Genetic diversity and population structure in contemporary house sparrow populations along an urbanization gradient

Redundancy analyses revealed that genetic structure was strongly affected by both spatial variation and level of urbanization, and principal coordinate analyses did not support the hypothesis that urban/suburban and rural populations comprise two distinct genetic clusters.

House sparrow (Passer domesticus) habitat use in urbanized landscapes

The house sparrow (Passer domesticus) is showing population declines in many parts of Europe, with recent declines being particularly severe in urban areas. To date, relatively little is known about

Resource availability and the persistence of seed-eating bird populations in agricultural landscapes : a mechanistic modelling approach

1. Reductions in resource availability, associated with land-use change and agricultural intensification in the UK and Europe, have been linked with the widespread decline of many farmland bird



Post‐war changes in arable farming and biodiversity in Great Britain

Summary 1. Agriculture represents the dominant land use throughout much of western Europe, and a significant part of European biodiversity is associated with this habitat. We attempted to quantify

Changes in the abundance of farmland birds in relation to the timing of agricultural intensification in England and Wales

1. Over the past three decades changes in agricultural management have resulted in increased crop and grass production. This intensification has been accompanied by population declines among farmland

Genetic structure of avian populations — allozymes revisited

The low levels of population subdivision measured with allozymes in birds seem to reflect historical and demographic processes and would not appear to result from any peculiarities of bird enzymatic loci.

The second Silent Spring?

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

Description and power analysis of two tests for detecting recent population bottlenecks from allele frequency data.

These analyses show that the most useful markers for bottleneck detection are those evolving under the infinite allele model (IAM) and they provide guidelines for selecting sample sizes of individuals and loci.

State of the States: The Status of Universal Newborn Hearing Screening, Assessment, and Intervention Systems in 16 States.

The survey establishes a baseline assessment that was conducted by states as part of their first year of participation in a Maternal and Child Health Bureau grant on state systems for universal newborn hearing screening, assessment, and intervention.

The migration atlas : movements of the birds of Britain and Ireland

Using a vast amount of data that the British Trust for Ornithology have collected from ringing recoveries, this title presents detailed and up-to-date information on bird migration. Since the ringing
