‘Citizen Scientists’ Seek Solutions to Bumblebee’s Problems
Hundreds of amateur1 “citizen scientists” have begun studying the Pacific Northwest area of the United States. They are seeking to learn more about the nearly 30 species2 of bumblebees that live there.
Bumblebees are important for the growth of wild and agricultural plants. They help spread the substances that make it possible for flowers to reproduce3 through the process known as pollination4.
But some bumblebee species have disappeared from the places where they were once common.
The new, three-year-long research effort is known as the Pacific Northwest Bumble Bee Atlas5 project. Organizations in Idaho, Oregon and Washington are working together as part of it.
Researchers hope to collect enough information to suggest ways to protect bumblebees and their habitat.
Ann Potter works with the Washington Department of Fish and Wildlife. She told the Associated Press it is important for humans to study honeybees – “the little guys that make the world go around.”
Rich Hatfield works with the conservation group the Xerces Society. He noted6 that there is growing interest in returning the habitats for pollinators to their earlier, healthier conditions.
The project’s leadership is sending citizen scientists to selected one-hectare sites. They will have tools to capture insects, as well as plant and bee guides. The amateur researchers will also have a special application, or app, on their smartphones. The app makes it so that findings can be recorded, photographed, mapped and sent to a central database7.
Researchers say a little more than 200 people have agreed to visit 400 sites through the end of August. Hatfield said more volunteers are needed, especially to work in more difficult-to-reach areas.
For the study, the bees are captured and put in a low-temperature container so that they go into a sleep-like state. Photos are taken that examine the condition of the bees. The bees are then released unharmed once they warm up.
Unlike honeybees, bumblebees do no spend the winter living in their self-made structures known as hives. Instead, they usually spend the winter in holes in the ground. There are usually only a few hundred individual bumblebees left alive by the time fall arrives. Any honey they produce they eat.
When winter begins, all bumblebees die except a few pregnant8 queen bees. In the spring, those queens head out alone to start a new structure to live and produce worker bees in, beginning the process all over again.
Andony Melathopoulos is with Oregon State University. His research interest centers on this period of bumblebees’ lives when they live alone.
“Here’s a species that spends a big part of its life as a vulnerable9 queen,” he said.
Honeybees first came to the United States from Europe. People brought them in order to help with the pollination of their crops.
But when it comes to native North American plants and some crops, bumblebees are much more useful. They are much stronger and can hold onto an entire flower, shaking loose the necessary substance for plant reproduction. For some plant species, the bumblebee is the only insect strong enough to do so.
The Western bumblebee was once considered common and widespread. But it has since disappeared from many of the areas it once lived in. And experts for the current study are hoping to find reasons for the sudden decrease in Western bumblebee populations.
Ross Winton of Idaho Fish and Game admitted that scientists do not know much about bumblebees.
“The more we learn, the more concerned we get,” he added.
In the end, the Pacific Northwest Bumble Bee Atlas could be an example for other states interested in learning more about how their bumblebee populations are doing.
Melathopoulos said, “I think everyone is looking at the Pacific Northwest and this initiative10 as a test case.”
The U.S. Fish and Wildlife Service is paying for the research done in Idaho and Washington. In Oregon, another government group called the Foundation for Food and Agricultural Research is providing financial support.
