USGS Biologist Captures a Bumble Bee
USGS biologist Stacy Simanonok captures a bumble bee in a net during a pollinator survey in the grasslands of the North Dakota plains. Researchers are testing environmental DNA sampling methods to determine if this less invasive way to survey for pollinators generates similar results as traditional netting methods.
