Nearly a third of managed honeybee colonies in America died out or disappeared over the winter, an annual survey found on Wednesday. The decline—which was far worse than the winter before—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 […]

Europe bans pesticides linked to bee collapse
The EU has banned three neonicotinoid pesticides (imidacloprid, clothianidin and thiamethoxam) linked to the decline of bees for two years. 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 […]
Saviours or villains: controversy erupts as New Zealand plans to drop poison over Critically Endangered frog habitat
New Zealand’s Department of Conservation (DOC) is facing a backlash over plans to aerially drop a controversial poison, known as 1080, over the habitat of two endangered, prehistoric, and truly bizarre frog species, Archey’s and Hochsetter’s frogs, on Mount Moehau. Used in New Zealand to kill populations of invasive mammals, such as rats and the […]
Domesticated bees do not replace declining wild insects as agricultural pollinators
Sprinkled with pollen, buzzing bees fly from one blossom to another, collecting sweet nectar from brilliantly colored flowers. 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 […]
Ban pesticides linked to bee deaths, say MPs
The UK government should suspend the use of a number of pesticides linked to the deaths of bees, a committee of MPs has said. Members of the Commons Environmental Audit Committee are calling for a moratorium on the use of sprays containing neonicotinoids. Britain has refused to back an EU ban on these chemicals saying […]
Neonicotinoid pesticides ‘damage brains of bees’
Commonly used pesticides are damaging honey bee brains, studies suggest. Scientists have found that two types of chemicals called neonicotinoids and coumaphos are interfering with the insect’s ability to learn and remember. Experiments revealed that exposure was also lowering brain activity, especially when the two pesticides were used in combination. The research is detailed in […]
Is it the end for Britain’s hedgehogs?
As hedgehogs all over the United Kingdom wake up from their winter hibernation, activists will be carefully counting their hogs. Every year, the hedgehog population in Britain’s rural towns declines by an estimated 5 percent. But between 2011 and 2012, a survey conducted by the People’s Trust for Endangered Species (PTES), a UK-based animal activism […]
Popular pesticides kill frogs outright
Commonly used agrochemicals (insecticides, fungicides and herbicides) kill frogs outright when sprayed on fields even when used at recommended dosages, according to new research in Scientific Reports. Testing seven chemicals on European common frogs (Rana temporaria), the scientists found that all of them were potentially lethal to amphibians. In fact, two fungicides—Headline and Captain Omya—wiped […]
