Walker Lake on a Spring day
April 24, 2017

USGS model simulations suggest that Walker Lake will rise by as much as 15 to 18 feet this year, the most in a single year in recorded history.

Hydrologic Regions of Alaska
April 14, 2017

While freshwater ecosystems cover only a small amount of the land surface in Alaska, they transport and emit a significant amount of carbon, according to new U.S. Geological Survey research. An invited feature article for Ecological Applications provides the first-ever major aquatic carbon flux assessment for the entire state. Carbon flux refers to the rate of carbon transfer between pools.

Dead and dying cottonwoods along the Mojave River, California, following a decrease in the riparian water table
January 17, 2017

Drought is killing riparian trees along many rivers in the western United States. The cause can be increasing temperature or decreasing precipitation, flow or water-table elevation. At multiple locations we are relating water availability to physiological measurements of tree survival and water stress, such as ring width, carbon stable isotope ratio and branch hydraulic conductivity....

Although there are ways of developing causal relationships between stressors and aquatic community responses without experimentation; some argue that experimental manipulation under controlled conditions is both critical and necessary to establish causation. Single species toxicity tests are the gold standard for developing toxicant biological response relationships however these tests are...

Natural resource agencies are challenged not only by climate change impacts on terrestrial and marine resources, but also by related effects on human communities that depend on these lands and waters. These effects include changes in economic activity, subsistence practices, demographic trends, human health, recreation, infrastructure, and community resilience. While there are many policy...

Bee
December 8, 2016

There is a lack of knowledge and understanding of how widespread use of pesticides may affect bees as they move across a diverse agricultural landscape. Studies have shown there are impacts to honey bees due to exposure to pesticides including neonicotinoid insecticides and fungicides, but the effects of these compounds on native pollinators are largely unknown....

December 8, 2016

Beginning in 2012, the USGS collaborated with the USDA to assess the effectiveness of pollinator plantings and how alteration of landscapes has affected native pollinators and potentially contributed to their decline. The 2008 Farm Bill recognized contributions made by pollinators and made conservation of pollinator habitat a priority. The USGS is assessing native bee habitat,...

Mountain goats in Glacier National Park, Montana
December 7, 2016

There is a well-known bias in the location of protected areas both within the US and globally. Lands protected for conservation tend to be located on less productive soils at high elevations far from cities. USGS is exploring whether this ‘high and far’ paradigm applies within protected areas as well. That is, does human modification within lands that already have some degree of...

Invasive Tamarisk or saltcedar as it is known, growing on the side of a river.
December 3, 2016

Due to high rates of disturbance and human activity, streamside or “riparian” areas are prone to colonization and spread of invasive plants. In the western United States, hundreds of thousands of riparian acres are occupied by the invasive shrubs/trees tamarisk and Russian olive, as well as numerous exotic herbaceous plants. Our work focuses on understanding the factors driving the...
