David Kleijn, Auteur ; Hans Schekkerman, Auteur ; Wim J. Dimmers, Auteur ; Ruud J. M. Van Kats, Auteur ; Dick Melman, Auteur ; Wolf A. Teunissen, AuteurAgricultural intensification is one of the main drivers of farmland bird declines, but effects on birds may be confounded with those of climate change.
