Rising levels of atmospheric carbon dioxide have reduced protein in goldenrod pollen, a key late-season food source for North American bees, a Purdue University study shows.

Researchers found that the overall protein concentration of goldenrod pollen fell about one-third from the onset of the Industrial Revolution to the beginning of the 21st century. Previous studies have shown that increases in carbon dioxide can lower the nutritional value of plants such as wheat and rice — staple crops for much of the … More Rising levels of atmospheric carbon dioxide have reduced protein in goldenrod pollen, a key late-season food source for North American bees, a Purdue University study shows.

Agricultural fungicide attracts honey bees

When given the choice, honey bee foragers prefer to collect sugar syrup laced with the fungicide chlorothalonil over sugar syrup alone, researchers report in the journal Scientific Reports. The puzzling finding comes on the heels of other studies linking fungicides to declines in honey bee and wild bee populations. One recent study, for example, found parallels … More Agricultural fungicide attracts honey bees

Woolworths and Coles cave in to pressure to abandon product accused of killing bees

Coles and Woolworths are abandoning an insecticide product which contains a controversial ingredient that has been linked to harming bee populations essential for pollination, The New Daily can reveal. More than 30,000 Australians have signed a petition, launched by global consumer group SumOfUs, calling on Australian retailers to stop selling insecticides containing neonicotinoids, including Yates Confidor which has been … More Woolworths and Coles cave in to pressure to abandon product accused of killing bees

Bee decline threatens US crop production

First US wild bee map reveals 139 ‘trouble zone’ counties The first-ever study to map U.S. wild bees suggests they are disappearing in the country’s most important farmlands — from California’s Central Valley to the Midwest’s corn belt and the Mississippi River valley. A new study of wild bees identifies 139 counties in key agricultural … More Bee decline threatens US crop production

A stinging report: Climate change a major threat to bumble bees

New research from a team of Florida State University scientists and their collaborators is helping to explain the link between a changing global climate and a dramatic decline in bumble bee populations worldwide. This is Bombus bifarius, one of the three species of bumble bee studied by the Ogilvie and her team. Credit: Jane Ogilvie … More A stinging report: Climate change a major threat to bumble bees

How honey bee gut bacteria help to digest their pollen-rich diet

he honey bee gut is colonized by specialized bacteria that help digest components of the floral pollen diet and produce molecules that likely promote bee health. In a study publishing 12 December in the open access journal PLOS Biology, a group of researchers led by Philipp Engel at the University of Lausanne and ETH Zürich, Switzerland, … More How honey bee gut bacteria help to digest their pollen-rich diet

Can Honeybees Monitor Pollution?

The tiny pollinators are useful sentinels of what’s going on in an ecosystem, and might just be environmentalists’ best asset.
