Mass flowering crops enhance pollinator densities at a landscape scale
The EU response to recent declines in pollinators and consequent loss of pollination services has been the inclusion of pollinator-friendly management in agri-environment schemes. These comprise the promotion of semi-natural habitats, such as set-aside and field margin strips. Yet, mass flowering crops, such as oilseed rape, are assumed to be of... view more... (2003-10-08)
Breast Feeding May Not Protect Against Obesity
