Mortality of Black-tailed Godwit Limosa limosa and Northern Lapwing Vanellus vanellus chicks in wet grasslands:Influence of predation and agriculture
Grassland-breeding shorebirds show widespread declines due to a reduction in breeding productivity following agricultural intensification. However, there is also concern that increasing predation causes further declines or precludes population recovery. Predation may itself be enhanced by agricultur...

Grassland-breeding shorebirds show widespread declines due to a reduction in breeding productivity following agricultural intensification.
