Scientists have long believed that pollinators are important for human nutrition, but this is first time they have tested the hypothesis. What they found is disturbing: pollinator collapse could increase nutrient deficiency across local populations by a up to 56 percent in four developing counties.

Bumblebees are essential insect pollinators that are vital to healthy crop yields and biodiversity, but their populations have been in decline.

But new research in the journal Nature find that these pesticides could also be taking a heavy toll on other species, in this case common birds.

Their bright coloration serves as a warning to predators that they are unwelcome prey and their bodies are covered in a fine coat of hair - known as pile - which gives them their characteristically fuzzy look. Bumblebees display a remarkably capable flight performance despite being encumbered with oversized bodies supported by relatively diminutive wings.

The EFSA says that current safety guidelines for two pesticides&#8212;acetamiprid and imidacloprid&#8212;may be too lax to protect humans, especially the developing brains of unborn children Jeremy Hance tag:news.mongabay.com,2005:Article/12540 2013-12-19T15:01:00Z 2014-12-28T19:57:07Z Top 10 HAPPY environmental stories of 2013 <table align="left"><tr><td><img src="http://s3.amazonaws.com/mongabay-images/13/1101olinguito.150.jpg" align="left"/></td></tr></table>China begins to tackle pollution, carbon emissions: As China's environmental crisis worsens, the government has begun to unveil a series of new initiatives to curb record pollution and cut greenhouse emissions. The world's largest consumer of coal, China's growth in emissions is finally slowing and some experts believe the nation's emissions could peak within the decade. If China's emissions begin to fall, so too could the world's.

Looking at ten bumblebee species in Colorado alpine meadows, two scientists found that removing a single bee species cut flower seed production by one-third. Pollinators worldwide are in major trouble as they are hit by habitat loss, pesticides, disease and other impacts. In fact, the EU has recently banned several pesticides that have been linked to the global bee decline.

A similar assessment by the EFSA on three other insecticides preceded the suspension of their use in the European Union.

The decline&#8212;which was far worse than the winter before&#8212;threatens the survival of some bee colonies. The heavy losses of pollinators also threatens the country's food supply, researchers said. The US Department of Agriculture has estimated that honeybees contribute some $20bn to the economy every year.

The ban will apply to all flowering crops, such as corn, rape seed, and sunflowers. The move follows a flood of recent studies, some high-profile, that have linked neonicotinoid pesticides, which employ nicotine-like chemicals, to the widespread decline of bees seen both in Europe and North America.

Bees tend to symbolize the pollination process, but there are many wild insects that carry out the same function. Unfortunately, wild insect populations are in decline, and, according to a recent study, adding more honey bees may not be a viable solution.

While the study is the first to record that popular pesticides directly injure bee brain physiology, it adds to a slew of recent studies showing that pesticides, especially neonicotinoids, are capable of devastating bee hives and may be, at least, partly responsible for on-going Colony Collapse Disorder (CCD).

The proposal comes shortly after European Food Safety Authority (EFSA) released a report that found neonicotinoid pesticides posed a "number of risks" to bees. Jeremy Hance tag:news.mongabay.com,2005:Article/10310 2012-10-24T17:12:00Z 2012-11-14T19:12:09Z New study adds to evidence that common pesticides decimating bee colonies <table align="left"><tr><td><img src="http://photos.mongabay.com/j/honeybee.hive.150.jpg" align="left"/></td></tr></table>The evidence that common pesticides may be partly to blame for a decline in bees keeps piling up. Several recent studies have shown that pesticides known as "neonicotinoid" may cause various long-term impacts on bee colonies, including fewer queens, foraging bees losing their way, and in some cases total hive collapse. The studies have been so convincing that recently France banned the use of neonicotinoid pesticides. Now a new study finds further evidence of harm caused by pesticides, including that bees who are exposed to more than one chemical, i.e. neonicotinoid and pyrethroid, were the most vulnerable.

Recent studies, including one in France, have shown that neonicotinoid pesticides likely hurt bees' ability to navigate, potentially devastating hives. France has said it will give Sygenta two weeks to prove the pesticide is not linked to the bee decline, known as Colony Collapse Disorder (CCD).

Bee populations have been dying mysteriously throughout North America and Europe since 2006, but the cause behind the decline, known as Colony Collapse Disorder, has eluded scientists. However, coming on the heels of two studies published last week in <i>Science</i> that linked bee declines to neonicotinoid pesticides, of which imidacloprid is one, the new study adds more evidence that the major player behind Colony Collapse Disorder is not disease, or mites, but pesticides that began to be widely used in the 1990s. Jeremy Hance tag:news.mongabay.com,2005:Article/9325 2012-03-29T18:00:00Z 2012-04-05T14:40:02Z Smoking gun for bee collapse? popular pesticides <table align="left"><tr><td><img src="http://photos.mongabay.com/j/frenchstudy.bees5HR.150.jpg" align="left"/></td></tr></table>Commonly used pesticides may be a primary driver of the collapsing bee populations, finds two new studies in <i>Science</i>. The studies, one focused on honeybees and the other on bumblebees, found that even small doses of these pesticides, which target insect's central nervous system, impact bee behavior and, ultimately, their survival. The studies may have far-reaching repercussions for the regulation of agricultural chemicals, known as neonicotinoid insecticides, that have been in use since the 1990s.

Researchers say the new bee has the longest tongue of any known bee, and may even have the world's longest tongue compared to body size of any animal: twice the length of the bee itself. The new species has been named Euglossa natesi in honor of bee-expert Guiomar Nates.

"Winning the Tyler Prize is an incredible honor—most of my scientific heroes have been Tyler Prize winners and I’m exceedingly grateful to be considered worthy of being included among their ranks," Berenbaum told mongabay.com in an interview. "The Prize is also tremendously enabling—because the money is unrestricted I can use it to carry out projects that have been difficult to fund." Jeremy Hance
