Carrying a tubed rattlesnake

Boise State University Master’s student Kristina Parker carries a Great Basin rattlesnake (Crotalus oreganus lutosus). The snake’s head is enclosed in a plastic tube to allow her to safely handle it during the biological sample collection process.

Alder root nodules

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. They also use a process called rock dissolution to release other nutrients, such as calcium and

Male leafcutting bee (Megachile) approaching an Origanum

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.

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. Little is known about the status of Pacific fishers, Pacific martens, and Sierra Nevada red foxes living in the Klamath Network, which include Crater Lake National Park, Lassen Volcanic National

Figure 1, Horn, et al. (2018)

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. Deposition data are from the TDEP product [23] and

Collecting larval fish for the Dragonfly Mercury Project

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 Dragonfly
