WASHINGTON (AP) — Winter hit U.S. honeybees hard with the highest loss rate yet, an annual survey of beekeepers showed.The annual nationwide survey by the Bee Informed Partnership found 37.7% of honeybee colonies died this past winter, nearly 9 percentage points higher than the average winter loss.The survey of nearly 4,700 beekeepers managing more than 300,000 colonies goes back 13 years and is conducted by bee experts at the University of Maryland, Auburn University and several other colleges.Beekeepers had been seeing fewer winter colony losses in recent years until now, said Maryland's Dennis vanEngelsdorp, president of the bee partnership and co-author of Wednesday's survey."The fact that we suddenly had the worst winter we've had ... is troubling," vanEngelsdorp said.Some bees usually die over winter, but until the past couple decades, when a combination of problems struck colonies, losses rarely exceeded 10%, he said.Bees pollinate billion worth of U.S. food crops. One-third of the human diet comes from pollinators, including native wild bees and other animals, many of which are also in trouble, according to the U.S. Department of Agriculture."We should be concerned on multiple levels," said University of California, Berkeley, agricultural social scientist Jennie Durant, who has a separate study this week on loss of food supply for bees.Year-to-year bee colony losses, which include calculations for summer, were 40.7%, higher than normal, but not a record high, the survey found."The beekeepers are working harder than ever to manage colonies but we still lose 40-50% each year... unacceptable," Swiss bee expert Jeff Pettis, who wasn't part of the survey, said in an email.For more than a decade, bees have been in trouble with scientists blaming mites, diseases, pesticides and loss of food.This past winter's steep drop seems heavily connected to the mites, vanEngelsdorp said. Beekeepers report that chemicals that kill mites don't seem to be working quite as well and mite infestation is worsening, he said. Those mites feed on the bees' fats and that's where the insects store protein and center their immune response.Durant's study in this week's journal Land Use Policy found that changes in food supply in the Midwest's Prairie Pothole Region, a hot spot for honeybee colonies, has been a major factor in losses. That area has lost wetland areas with clover bees feed on.Other areas have been converted to corn and soy crops, which don't feed bees, she said.As bad as the survey numbers are, vanEngelsdorp said, "We're not really worried about honeybees going extinct... I'm more worried that the commercial beekeepers will go out of business." 2695

WASHINGTON (AP) — The Department of Homeland Security has asked the military to provide more help securing the U.S.-Mexico border, two defense officials said Friday amid a political standoff over President Donald Trump's demand for more money to build a border wall.The acting secretary of defense, Pat Shanahan, has not decided how to respond to the DHS request, but in the past the Pentagon has provided help when asked. At one point last fall there were nearly 5,900 active-duty troops along the border in Texas, Arizona and California to assist border patrol agents and to erect wire barriers. That number now is about 2,350.The defense officials said DHS asked for certain military capabilities, not any number of troops. It will be up to Shanahan to decide whether more active-duty troops are dispatched. The officials spoke on condition of anonymity because the request for assistance has not yet been fully processed.One of the officials said DHS wants the military to put up concertina wire as barriers along 160 miles of border. That would be in addition to 70 miles of concertina wire that combat engineers put up last fall. If the new work is taken on by the military, it might require an extension of the current deployment beyond its scheduled end Jan. 31. The official said DHS did not specifically ask for an extension, but it has not been ruled out.The troops have been erecting and reinforcing border barriers but are not performing law enforcement tasks or engaging with migrants. Some also have been providing transportation and logistical help as well as medical assistance to troops and to Customs and Border Protection personnel along the border.Many in Congress, including leading Democrats, have criticized the troop deployments as a waste of money and a misuse of military resources.Separately, there are about 2,200 National Guard troops deployed along the border. It is possible that some of those, or additional deployments of National Guard personnel, could be used to perform some of the work requested by DHS. 2049

WASHINGTON, D.C. – What police reform proposals will get the endorsement of President Donald Trump and Senate Republicans?While House Democrats have already announced what legislation they are seeking, Republicans in the Senate, as well as the White House, have been more mum.That is expected to change this week.Sen. Tim Scott (R-SC) is working with the White House on what ideas the president could support. Scott is the only African American senator in the Republican caucus.White House officials hinted the president would likely provide more guidance on what he supports and what he doesn't when he travels to Dallas, Texas, on Thursday.CNN reported Wednesday that the president is considering an executive order on police reform, which would not require Congress' approval.“We’re still wrestling with America’s original sin,” said Senate Majority Leader Mitch McConnell, referring to slavery, when he spoke with reporters Tuesday.“We try to get better but every now and then it’s perfectly clear we’re a long way from the finish line,” said McConnell. 1065

  

WASHINGTON (AP) — President Donald Trump is expected to announce a new federal rule to speed up the environmental review process for proposed highways, gas pipelines and other major infrastructure.Critics are describing the move as a dismantling of a 50-year-old environmental protection law.Trump will travel to Atlanta on Wednesday to announce the federal rule as he seeks to make it easier to meet some of the country’s infrastructure needs.The government affairs director at the Center for Biological Diversity, Brett Hartl, says such a change may be the single biggest giveaway to polluters in the past 40 years. 625
