Boise State University Master’s student Kristina Parker uses a syringe to collect blood from a Great Basin rattlesnake (Crotalus oreganus lutosus). The blood’s ribonucleic acid, or RNA will be analyzed to track genetic change in the snake from habitat disturbances. RNA, along with deoxyribonucleic acid – or DNA, are the molecules that carry genetic information.

Experimental site in the Snake River Plain in southwest Idaho three years post-herbicide treatment. The plot towards the lower left of the image was not treated with herbicide. The plot towards the upper right was treated with the pre-emergent herbicide imazapic and is free of cheatgrass. This is one of the longest-lasting imazapic treatments recorded.

Root nodules are a symbiotic relationship between a plant and nitrogen-fixing bacteria. A symbiotic relationship is one where both organisms benefit. Nitrogen-fixing bacteria change inorganic nitrogen from the air into ammonia, a form of nitrogen most organisms can use.

The alfalfa leafcutting bee (Megachile rotundata) is an introduced species common to Southwest Idaho. They originate from the old world, most likely from northeastern Africa or the Middle East. These bees are successful pollinators of various crops and have been imported to North America for use in agriculture and beekeeping.

In August of 2018 this adult female golden eagle was captured and outfitted with a GPS transmitter. You can see the transmitter on the eagle’s back, below the head. This was the first golden eagle ever captured as part of a research project in Yellowstone National Park.
