Snow geese captured on Wrangel Island, Russia in July of 1991 and 1992. The project involved using satellite transmitters to track the migration of the geese.

Dr. Jacqueline Savino, fishery biologist, and Gentry Yearout, volunteer, remove fish for research from a tank in the fish holding room at the Great Lakes Science Center.

Here is a study deer after capture and being radio-collared. The tracking information from this collar will enable researchers and managers to track the migrations of mule deer and evaluate their habitat and population performance and will aid in management of mule deer populations in Wyoming.

The red color is due to the abundance of this organism; the red is due to the presence of astaxanthin, a pigment in the cells.

The USGS researches land use and honey bee health in the northern Great Plains. This research will be useful in equipping land managers and policy makers with the best-available science to improve forage and habitat for pollinators in a part of the country that is undergoing rapid land-use change.

Honey bees live and work in highly collaborative, social colonies with a sole reproducing queen, and they make honey by storing nectar from flowering plants in their hives for use during food scarcities.
