Field ‐ margin diversification through conservation and restoration of hedgerows is becoming a prominent intervention for promoting biodiversity and associated ecosystem services in intensive ...
at the centre, edges and boundaries of 29 organic and 29 conventional cereal fields distributed in 15 agrarian localities of the NE Iberian Peninsula. We focused on the composition of plant assemblages ...
increased from 2% to 75%. The impoverishment of vegetation was slightly less pronounced at field margins , where around one quarter of the recent relevés could be assigned to associations. Present arable plant ...
PECs (Miscanthus x giganteus and willow short‐rotation coppice), we examine whether pollinator visits to crop margin wildflowers were augmented by PEC cultivation. Each field was paired with two cereal ...
cereals (wheat, barley, rye and triticale; data pooled), maize or potato. The presence of grassy strips and ditch margins adjacent to fields increased plant richness at field edges presumably through ...
diversity of crops and thus losses in associated arable plants . Stands have generally become much denser with species that are poor competitors for light increasingly being confined to field margin sites ...
prepupae and pupae in the soil caused about 50% extra mortality. This mortality will have reinforced the effects of host‐ plant requirements, suppressing sawfly numbers in annually cultivated cereal fields ...
(∼100% arable land) to complex landscapes (up to 70% semi‐natural habitats such as fallows, field margins , hedges and grassland). Landscape complexity was assessed within landscape sectors of 0·5–4·0 km ...
, suggesting plant ‐mediated effects of the farming system. 4 Differences in bee diversity between organic and conventional fields increased with the proportion of arable crops in the surrounding landscape ...
those on the sandland. On sandland, slopes were steeper in eroded fields drilled to winter cereals than they were in fields planted to potatoes or sugarbeet. Such field ‐ based studies hint at the complex ...
