Piscicides have been used in Rocky Mountain stream and lakes to restore native fish populations. In the last two decades concerns over piscicide effects to non-target organisms, primarily aquatic invertebrates, has increased. Although piscicides have been used for more than 70 years the impact to invertebrate assemblages has not been well studied and is largely unknown. Given the...

August 16, 2016

Wetlands of the northern Great Plains are crucial feeding grounds for migrating birds and waterfowl embedded in an agricultural landscape. Land use and hydrology can affect adult aquatic insects – crucial prey for critically declining populations of insectivorous birds. Current studies focus on effects of current-use pesticides on adult aquatic insects to inform decision making about...

August 12, 2016

Water quality and aquatic life standards that are set by Federal and state regulatory agencies are used to evaluate the quality of our nation’s water and the health of aquatic ecosystems. These standards currently are based on hardness of the water and are determined for single metals, not for mixtures of metals that are typically found in natural systems. Metal mixtures can...

Map of all the reservoir sediment sites going on in Kansas
August 5, 2016

In Kansas and nationally, sediment is a concern for both physical and chemical reasons. Physically, problems caused by excessive sediment may include degraded water quality, degraded aquatic habitat, increased water-treatment costs, decreased channel capacity, clogged water intakes, and loss of water-storage capacity in reservoirs. Chemically, sediment serves as a carrier for various...

This photo of a Pacific sheath-tailed bat is the last good photo of this bat from Aguiguan in existence.
August 1, 2016

Bats are the only flying mammals that are active mostly at night and occur on all continents except Antarctica. Bats are ecologically diverse, with a range of species that specialize in feeding on fruit, nectar, blood, fish, small mammals, and insects. However, of the more than 1,100 known species of bats on Earth, the majority specialize in feeding on insects. In the United States for example...

Kansas
July 28, 2016

The Kansas River is a primary source of drinking water for about 800,000 people in northeastern Kansas. Water-quality concerns related to excessive nutrient, bacteria, and sediment concentrations have been identified by the Kansas Department of Health and Environment. Additionally, the occurrence and transport of cyanobacteria (also called blue-green algae), associated toxins, and taste-and-...

A crowd of people in a National Park.
July 26, 2016

The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. USGS economists collaborate with the National Park Service social science program to estimate...

July 21, 2016

Unexplained heterogeneity in statistical models of animal responses to their physical environment is reasonable to expect because the measured habitat resources are a constraint on—but not the sole determinant of—abundance, survival, fecundity, or fitness. The ecological understanding and reliability of management predictions based on animal habitat models can...

Flyover of the southeast Ceti Mensa map. Distinct groups of rock layers, called geologic units, are shaded in different colors, with dark browns representing the oldest rocks and green representing the youngest rocks. All of these rocks formed as wind-blown sand that became trapped in shallow, ephemeral lakes, similar to the wet playas of the desert southwest US. The irregularly-shaped green unit...

Arid and semiarid ecosystems are expected to experience significant changes in temperature and precipitation patterns, which may affect soil organisms in ways that cause surfaces to become lighter in color and thus reflect more sunlight, according to a new U.S. Geological Survey study.

Lake Mead
March 15, 2017

The Colorado River system provides about 35 million Americans with a portion of their water supply. It irrigates 5½ million acres of land in the West and provides water to tribes, parks, and wildlife. The system serves parts of seven States and Mexico—but reservoir levels have crept lower over the past several years, sparking questions about how much water remains and who will have access.
