New research finds climate change is making allergy season arrive earlier and bring higher pollen loads in North America. The phenomenon of increasing yearly pollen loads is accelerating. Human-caused climate change is making allergy season longer and more severe, reports Seth Borenstein for the AssociatedPress. In North America, there is now 21 percent more pollen … More Climate Change Is Making Allergy Season Worse.
Wild bees are more affected by climate change than by disturbances to their habitats, according to a team of researchers led by Penn State. The findings suggest that addressing land-use issues alone will not be sufficient to protecting these important pollinators. “Our study found that the most critical factor influencing wild bee abundance and species diversity was the weather, particularly … More Climate change reduces the abundance and diversity of wild bees.
A new study from Northwestern University and the Chicago Botanic Garden has found that climate change may drive local extinction of mason bees in Arizona and other naturally warm climates. In a two-year, in situ field experiment that altered the temperature of the bees’ nests to simulate a warmer, future climate, 35 percent of bees … More Climate change linked to potential population decline in bees.
The first definitive demonstration of climate change upsetting the vital interdependent relationships between species has been revealed. The first definitive demonstration of climate change upsetting the vital interdependent relationships between species has been revealed, thanks to a study led by the University of Sussex. Research led by Prof Michael Hutchings at the University of Sussex tracks how … More Climate change is wreaking havoc on delicate relationship between orchids and bees.
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.
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
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
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
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
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
