摘要: The promotion of biodiversity in agricultural areas involves actions at the landscape scale, and management cropping patterns is considered an important means achieving this goal. However, most available knowledge about impact crops on has been obtained field generally grouped together under umbrella term " crop suitability. Can field-scale be used to predict populations across landscapes? We studied maize rapeseed abundance skylark (Alauda arvensis). Field-scale studies Western Europe have reported diverse impacts habitat selection demography. assessed consistency between landscape-scale observations, using high-resolution databases describing other habitats for 4 km 2 grid scales analyzed French Breeding Bird Survey. generalized linear models estimate each scale. stratified squares according local geographical contexts, ensure that conclusions drawn were valid a wide range contexts. Our results not consistent with rapeseed, only grassland effect sizes much smaller than those structural features. These suggest upscaling from scale leads integration new agronomic ecological processes, making objects more complex simple * species pairs. conclude carrying capacity landscapes cannot deduced suitability their components.
