Compared to other species of bumblebee, American bumblebees in Canada in recent years have decreased in abundance by 89%, a new study found.
A group of scientists from York University and University of Vermont looked at three different measurements and found that Bombus pensylvanicus, commonly known as the American bumblebee, is declining in Canada. The number of areas where the American bumblebee can be found in the country decreased by 70% from historical rates, according to the study. Bees are dying -- what can we do about it?Compared to other species of bumblebee, American bumblebees have decreased in abundance in Canada by 89%.
"Native bees indispensable to the health of the natural world are declining globally due to accelerating threats from agricultural expansion, habitat loss and climate change."These particular American bumblebees are considered a keystone species and are critical for the functioning of ecosystems where they live."They're very good pollinators from spring through fall. To lose them could have an impact on the environment," MacPhail said.
