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.

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.

TL;DR: Aphid populations were 28%, 97%, and 199% higher in -G, -V, and -G-V treatments, respectively, compared to the open fields, indicating synergistic effects of both natural-enemy groups.

TL;DR: In eight European study sites (in Spain, Ireland, Netherlands, Germany, Poland, Estonia and Sweden), abundance of breeding farmland bird territories was obtained from 500 × 500 m survey plots (30 per area, N = 240) using the mapping method as mentioned in this paper.

TL;DR: The results confirmed that persistent negative effects of pesticides on biodiversity and biological control potential on European farmland are stillpersistent and pose a threat to species survival.
