Flavia Geiger,Jan Bengtsson,Frank Berendse,Wolfgang W. Weisser,Mark C. Emmerson,Manuel B. Morales,Piotr Ceryngier,Jaan Liira,Teja Tscharntke,Camilla Winqvist,Sönke Eggers,Riccardo Bommarco,Tomas Pärt,Vincent Bretagnolle,Manuel Plantegenest,Lars W.

Goedhart,Pablo Inchausti +27 more
TL;DR: Of the 13 components of intensification the authors measured, use of insecticides and fungicides had consistent negative effects on biodiversity, and organic farming and other agri-environment schemes aiming to mitigate the negative effects are found.
Journal ArticleDOI
Age and reproduction in birds — hypotheses and tests
Pär Forslund,Tomas Pärt +1 more
TL;DR: A closer examination of the literature reveals that only few studies have rigorously tested the hypotheses relating to progressive appearance or disappearance of phenotypes, age-related improvements of competence, and optimization of reproductive effort.
Journal ArticleDOI
Breeding dispersal in the collared flycatcher (ficedula albicollis): possible causes and reproductive consequences
Tomas Pärt,Lars Gustafsson +1 more
TL;DR: The hypothesis is advanced that breeding dispersal distances reflect individual choices among available territories, in that individuals with little and/or bad local experience disperse more because they benefit from exploring more sites before.
Journal ArticleDOI
Agricultural intensification and biodiversity partitioning in European landscapes comparing plants, carabids, and birds
Andreas Flohre,Christina Fischer,Tsipe Aavik,Jan Bengtsson,Frank Berendse,Riccardo Bommarco,Piotr Ceryngier,Lars W. Clement,Christopher Dennis,Sönke Eggers,Mark C. Emmerson,Flavia Geiger,Irene Guerrero,Violetta Hawro,Pablo Inchausti,Jaan Liira,Manuel B. Morales,Juan J. Oñate,Tomas Pärt,Wolfgang W. Weisser,Camilla Winqvist,Carsten Thies,Teja Tscharntke +22 more
TL;DR: Local AI was closely correlated to beta diversity on larger scales up to the farm and region level, and thereby was an indicator of farm- and region-wide biodiversity losses, and in contrast to expectations, AI does not necessarily homogenize local communities, presumably due to the heterogeneity of farming practices.
Journal ArticleDOI
Mixed effects of organic farming and landscape complexity on farmland biodiversity and biological control potential across Europe
Camilla Winqvist,Jan Bengtsson,Tsipe Aavik,Frank Berendse,Lars W. Clement,Sönke Eggers,Christina Fischer,Andreas Flohre,Flavia Geiger,Jaan Liira,Tomas Pärt,Carsten Thies,Teja Tscharntke,Wolfgang W. Weisser,Riccardo Bommarco +14 more
TL;DR: In this paper, the authors examined how the species richness and abundance of wild plants, ground beetles and breeding birds, and the biological control potential of the area, were affected by organic and conventional farming, and how these effects were modified by landscape complexity.
