Cyanobacteria of the 2016 Lake Okeechobee and Okeechobee Waterway harmful algal bloom
The Lake Okeechobee and the Okeechobee Waterway (Lake Okeechobee, the St. Lucie Canal and River, and the Caloosahatchee River) experienced an extensive harmful algal bloom within Lake Okeechobee, the St. Lucie Canal and River and the Caloosahatchee River in 2016. In addition to the very visible bloom of the cyanobacterium Microcystis aeruginosa,...

Subsidence Induced by Underground Extraction
Subsidence induced by underground extraction is a class of human-induced (anthropogenic) land subsidence that principally is caused by the withdrawal of subsurface fluids (groundwater, oil, and gas) or by the underground mining of coal and other minerals.

U.S. Geological Survey National Water Census: Colorado River Basin Geographic Focus Area Study
Introduction The U.S. Geological Survey’s (USGS) concept of a national census (or accounting) of water resources has evolved over the last several decades as the Nation has experienced increasing concern over water availability for multiple competing uses. The implementation of a USGS National Water Census was described in the USGS 2007...

As part of the surface-water drainage system of the Albuquerque metropolitan area, numerous ephemeral channels collect and transport surface water through the urban area and, eventually, into the Rio Grande.
Reconstructing Flow History From Riparian Tree Rings
Aquatic Systems Branch scientists analyze rings of riparian trees relating tree growth and establishment to historical flow. We then use the tree rings to reconstruct the flow in past centuries. Flow reconstructions discover the frequency and magnitude of past droughts and floods—information that is essential for management of rivers and water supplies. We also use downscaled climate...

Aquatic invertebrates are a key component of freshwater ecosystems, and an understanding of aquatic invertebrate taxonomy is central to freshwater science.

Ecological Drought in Riparian Ecosystems
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. These...
Pesticide Exposure to Native Bees in Agricultural Landscapes
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.
Native Pollinators in Agricultural Ecosystems
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, diversity, and...
Higher and Farther: Patterns of Development within Protected Areas
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 protection,...
Biology, Impacts and Control of Invasive Reptiles
Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles.
Ecology and Management of Invasive Riparian Plants
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...
Erosion and Invasive Saltcedar
Formation of arroyos in the late 1800s greatly increased erosion across the southwestern United States. Since the 1930s, however, this erosion has decreased, partly because of bank stabilization by introduced saltcedar. With Isleta Pueblo Indian Nation, the Aquatic Systems Branch developed a new sediment dating method using saltcedar tree rings. We applied the method in a landmark study of...
