Two young golden eagles fight in the snow. In the winter, eagles tend to scavenge for food as prey become scarce.

This is a young golden eagle in its third winter. Golden eagles generally don't reach adulthood until about their fifth year.

There are two juvenile golden eagles. Golden eagles are one of the largest birds in North America. They have a wingspan from 72.8 to 86.6 inches.

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.

USGS scientists are documenting the distribution of three mid-sized mammalian carnivores – or mesocarnivores –in the Klamath Network Parks using remote cameras and hair snares.

Gradients of N deposition, S deposition, mean annual temperature, and mean annual precipitation across the conterminous U.S. Panels are the a) mean total N deposition from 2000–2012, b) mean total S deposition from 2000–2012, c) mean annual temperature from 2000–2014, and d) mean annual precipitation form 2000–2014.

Between 2009 and 2018, scientists conducted a national scale assessment of mercury accumulation in the National Park System using dragonfly larvae as biosentinels (species that accumulate a pollutant in their tissues as an index of exposure to other organisms without significant adverse effects to the biosentinel) through a citizen science network called the Dragonf

Photovoltaic, or solar, cells array at the Ivanpah Solar Power Facility in the Mojave Desert and a wind energy facility in the Northeastern United States.

The Land Treatment Planning Tool provides a practical resource for managers who are planning restoration and rehabilitation actions on public lands. The Planning Tool is a user friendly, web-based interface to Geographic Information System (GIS) maps and tools, and requires little to no GIS experience to generate a variety of spatial products.
