1. Birds and butterflies at the forest-farmland interface
Sammanfattning : Land-use change is one of the greatest threats to biodiversity. Through intensification of land-use, the agricultural landscape has become more homogenous and a result, many species associated with traditional farmland or other semi-natural open habitats have declined. LÄS MER
2. On starlings and farming: population decline, foraging strategies, cost of reproduction and breeding success
Sammanfattning : The European Starling Sturnus vulgaris as many other farmland bird species has been declining during the last decades. The cause of these declines is generally believed to be changes with in agricultural methods affecting breeding and survival of birds. LÄS MER
3. On the importance of farmland as stopover habitat for migrating birds
Sammanfattning : Agricultural intensification has led to dramatic population declines among many farmland bird species. Negative effects of intensive farming in terms of decreased local habitat quality or structural simplification of farmland landscapes have reduced both reproductive outcome and winter survival of many species. LÄS MER
4. Effects of created habitats on farmland biodiversity
Sammanfattning : Agricultural intensification has caused severe declines among biodiversity in European farmland over the last half century. The transformation of the agricultural landscape has led to reduced availability of key resources such as food, nesting habitat and shelter. LÄS MER
5. Biodiversity conservation in agricultural landscapes : linking farmers and agri-environmental measures to farmland birds
Sammanfattning : Agricultural industrialization alters rural landscapes in Europe, causing large-scale and rapid loss of important biodiversity. The principal instruments to protect farmland biodiversity are various agri-environmental measures (AEMs) in the EU Common Agricultural Policy (CAP). LÄS MER
