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.

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.

The fourth webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on movement of bird species associated with Great Basin terminal lake ecosystems. Cory Overton of the Western Ecological Research Center gives an overview of the USGS bird movement monitoring strategy and presents results from the 2024 field season.

The third webinar in the Saline Lakes Ecosystems IWAA Fall 2024 Webinar Series is on water-quality monitoring of Great Basin terminal lake ecosystems. Christine Rumsey of the Utah Water Science Center and Casie Smith of the Oregon Water Science Center give an overview of the USGS water-quality monitoring strategy and present results from the 2024 field season.

The second webinar in the Saline Lake Ecosystems IWAA Fall 2024 Webinar Series is on physical and chemical monitoring in support of water budgets of select Great Basin saline lakes.

Field technicians collect soil samples and monitor plants in an invasive grass dominated sagebrush steppe ecosystem in Colorado. The team measured carbon levels at two soil depths at undisturbed sites, sites that have been burned and invaded, areas that are unburned but invaded, and sites that were burned but not invaded.

Allison Shipp, Deputy Regional Director for Science and Research and Saline Lake Ecosystems IWAA Project Manager, kicked off the Fall 2024 webinar series. This presentation gives an overview of the project and introduces topics that will be covered by the USGS research team throughout the webinar series.

American Avocet 39’s (AMAV39) year long journey detailed by U.S. Geological Survey (USGS) GPS tracking data. AMAV39’s flight path, represented by a purple line, starts in the Great Basin at Summer Lake in July 2023 then heads to Lake Abert in October 2023.

A sequence of satellite imagery of Summer Lake in southern Oregon from May 2024 – July 2024. Starting in May the lake is full and a deep-blue color. As the sequence of satellite images progresses through the summer the lake shrinks dramatically as water evaporates. By July the lake has dried out completely and only some marshlands remain.
