Declines in bee populations and other pollinators could negatively affect crop yields in the US, according to new research published in the journal Proceedings of the Royal Society B: Biological Sciences. The study led by Rutgers University researchers found that a lack of pollinators could translate directly into decreased yields of key crops such as apples, cherries and blueberries. “We found that many crops are pollination-limited, meaning crop production would be higher if crop flowers received more pollination,” said senior author Rachael Winfree from the School of Environmental and Biological Sciences at Rutgers University–New Brunswick. “We also found that honey bees and wild bees provided similar amounts of pollination overall,” she added. The authors stress that their study is the first to evaluate the contribution of wild pollinators to crop pollination at the national scale in the US in such a comprehensive way. [+] more ...
