  1. 1. Pollinators and Insect Pollination in Changing Agricultural Landscapes

    Författare :Lina Herbertsson; Miljövetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pollinators; pollination; agri-environment schemes; beekeeping; oilseed rape; sown flower strips; agri-environment measures;

    Sammanfattning : Agricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. LÄS MER

  2. 2. Small biotopes in agricultural landscapes: importance for vascular plants and effects of management

    Författare :Therese Irminger Street; Biodiversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Small biotopes; incidental habitat; vascular plants; woody vegetation; grassland species; resource provisioning; species richness; habitat specificity; non-crop habitat; landscape complexity; heterogeneity; local management; agri-environment scheme;

    Sammanfattning : As a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is not fully understood.
