New Computer Model Could Preserve The World's Bee Colonies
2014-03-04 15:25:51

Lee Rannals for redOrbit.com - Your Universe Online Scientists have created a new computer model to help understand the environmental effects of a honeybee colony. The BEEHAVE model published in the Journal of Applied Ecology was created to investigate the losses of honeybee colonies that have been reported recently and to identify the best way to try and combat the losses. [ Watch the Video: BEEHAVE Model ] "It is a real challenge to understand which factors are most important in...

Bees Almost Went Extinct With Dinosaurs
2013-10-24 13:38:51

Brett Smith for redOrbit.com - Your Universe Online According to numerous reports, honey bees around the world are facing a mysterious threat that has been wiping out entire colonies. However, this isn’t the first time bees have faced an existential threat. According to a new study in the journal PLOS ONE, the flying insects were almost wiped out along with the dinosaurs 65 million years ago. In the study, a team of Australian and American researchers modeled a mass extinction event...

Exposure To Pesticides Key Factor In Causing Bee Colonies To Fail
2013-10-07 07:17:03

Royal Holloway, University of London Scientists from Royal Holloway University have found that when bees are exposed to low levels of neonicotinoid pesticides - which do not directly kill bees - their behavior changes and they stop working properly for their colonies. The results showed that exposure to pesticides at levels bees encounter in the field, has subtle impacts on individual bees, and can eventually make colonies fail. This discovery provides an important breakthrough in...

Betrayal By Bees Could Have Huge Impact On Plant Reproduction
2013-07-23 09:05:30

April Flowers for redOrbit.com - Your Universe Online A new study led by Emory University finds removing even one species of bumblebee from an ecosystem has a swift and clear impact: the floral "sweethearts" of that species produce significantly fewer seeds. The research team focused on the interactions between bumblebees and larkspur wildflowers in Colorado's Rocky Mountains. The findings, to be published by the Proceedings of the National Academy of Sciences, reveal how reduced...

Tighter Controls On Bee Imports Needed To Reduce Disease Risk To Native Populations
2013-07-18 15:19:49

Lee Rannals for redOrbit.com - Your Universe Online Researchers, publishing a study in the Journal of Applied Ecology, wrote that stricter controls over bee imports are needed in order to prevent diseases from spreading to the native bumblebee and honeybee populations. Farmers bring in commercially-produced and imported bumblebees for pollination of greenhouse crops like tomatoes. These bees are used to enhance pollination of other food crops, such as strawberries, and are marketed for...

Flowering Agri-environment Schemes Easily Enhance Pollinators
2013-06-10 13:43:51

Pensoft Publishers Agri-environment schemes aimed to promote biodiversity on farmland have positive effects on wild bees, hoverflies and butterflies. Effects on diversity and abundance were strongest when agri-environment schemes prescribed sowing wild-flowers, the more flowering species the better. Organic farms, set-aside land or fields receiving reduced amounts of fertilizer and pesticides generally hosted more wild pollinators than conventionally farmed land. Jeroen Scheper of Alterra...

WASHINGTON, April 19, 2013 /PRNewswire-USNewswire/ -- With honey bees suffering a devastating decline as high as 90 percent as Earth Day approaches, national environmental groups, Beyond Pesticides and Center for Food Safety, launch a campaign called BEE Protective to support nationwide local action aimed at protecting honey bees and other pollinators from pesticides. Pollinators are a vital part of the environment, a barometer for healthy ecosystems, and critical to the nation's food...

Nature Conservancy scientist's work suggests that this Earth Day, keeping the picnic basket full may depend on wild bees. Arlington, VA (PRWEB) April 16, 2013 Two recently released studies co-authored by The Nature Conservancy´s Christina M. Kennedy underscore just how important wild bees are to global agricultural production. Bees may seem like uninvited guests at a picnic, but before they're shooed away from the fruit salad, people should consider the role they play in bringing food...

The Pollination Game Is Greatly Affected By A Changing Climate
2013-03-01 12:34:02

Brett Smith for redOrbit.com - Your Universe Online The relationships among species change over time as shifts in an ecosystem begin to affect the organisms living in them. Climate change has placed a new emphasis on studying these shifting relationships and a team of biologists from the Midwest sifted through historical scientific logs to find that the plant-pollinator relationships in their area have been significantly altered over the past 120 years. Working out of Washington...

Bee Monitoring System Could Serve As Early Warning System For Global Food Shortages
2012-12-20 16:19:51

Lawrence LeBlond for redOrbit.com - Your Universe Online A United Nations-sponsored study has developed a new method to monitor global bee populations. The method, which will see regular bee counts over a five year period, should also serve as an early warning system alerting scientists to dangers threatening the world´s food and economic system. The work has been spearheaded by San Francisco State University Professor of Biology Gretchen LeBuhn. She and her colleagues, who...
