In this webinar, Mike Runge talks about the linkages between normative methods of decision analysis (i.e., structured decision making) and the RAD framework. First, what does SDM contribute to RAD?

This video presents the Spring 2026 Saline Lake Ecosystems Integrated Water Availability Assessment Spring Seminar by the U.S. Geological Survey (USGS). Narrated by Lisa Hoaks, the seminar provides project updates, summer 2026 field season plans, and recently published products.

RAD and Adaptive Management Webinar, part of the NCASC Webinar Series: Incorporating the RAD (Resist-Accept-Direct) Framework into Resource Management Planning.

USGS science on chronic wasting disease (CWD) tackles multiple facets of this complex management challenge.

This is B-roll video of the Kugururok River, Noatak National Preserve, Alaska from August 30, 2025.

Rusting rivers are increasingly common in the Brooks Range of northern Alaska. The orange stream color reflects oxidized iron (hence the appearance of rusting), but orange color also indicates elevated heavy metal concentrations and impaired water quality.

RAD is intended to help managers intentionally expand their thinking beyond traditional conservation approaches. Recent interdisciplinary and cross-agency research has integrated the social sciences to explore how and why managers are making RAD decisions.

This mesmerizing video, recorded by Tobyn N. Rhodes, is from USGS Western Fisheries Research Center’s field work on the lower Salmon River this past Fall 2025. Partnering with the Nez Perce Tribe, Rhodes and his team were counting the number of fall Chinook salmon nests, known as redds, with a drone piloted from a jet boat.

This is a video of a juvenile sucker in Upper Klamath Lake, OR. Through decades of research, scientists at the USGS Western Fisheries Research Center have determined that over the last 30 years something has prevented young suckers from reaching adulthood. Scientists work tirelessly to find the cause of this break in recruitment into adulthood.

Decades of invasive smallmouth bass removal from the Adirondacks resulted in a novel discovery of rapid evolution. Despite the absence of a clear physiological adaptation pathway, intensive manual removal produced a larger population of the invasive predatory fish, growing faster and maturing earlier.

Climate refugia are places that may be buffered from and likely won’t change as much under climate change. Focusing research on these areas may offer resource managers more conservation and management options.

Ammonia or ammonium? What’s the difference? In water, ammonia (NH₃) and ammonium (NH₄⁺) exist together in an equilibrium that depends on pH and temperature. As the temperature or pH rise, ammonia (NH₃) becomes more abundant. This is important because ammonia is more toxic than ammonium.

This video presents the Spring 2025 Saline Lake Ecosystems Integrated Water Availability Assessment Spring Seminar by the U.S. Geological Survey (USGS). Hosted by Allison Shipp, the seminar provides updates on how hydroclimatic changes and water management affect terminal lake ecosystems and waterbird populations.

This animated nitrogen fixation video provides an overview of natural and industrial nitrogen fixation, along with benefits, costs, trends, and effects on ecosystems.

The sixth and final webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on satellite observations of lake surface water dynamics. John W. Jones of the USGS Hydrologic Remote Sensing Branch introduces the surface water and wetland remote sensing component of the Integrated Water Availability Assessment.

The fifth webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on waterbird prey availability in Great Basin terminal lakes.
