The results come from the National Bumblebee Nest Survey, which are published online in the British Ecological Society's Journal of Applied Ecology, and the findings will help conservationists understand – and hopefully address – the factors responsible for declining bumblebee populations.

The sugar-containing nectar secreted by plants and consumed by pollinators shares a number of similarities to fitness drinks, including ingredients such as amino acids and vitamins. In addition to these components, nectar can also contain secondary metabolites such as the alkaloid nicotine and other toxic compounds.
