Realizing the potential of eDNA biodiversity monitoring tools in the marine environment with application to offshore renewable energy

The U.S. Geological Survey (USGS) researches the biological diversity and distribution of species to support management, conservation, and resource use decisions. USGS scientists advance detection and monitoring technologies to assess changes in fish and wildlife populations, biodiversity, and the health of ecosystems. The United States is planning to install 30 gigawatts of offshore marine and wi

READI-Net—Providing tools for the early detection and management of aquatic invasive species

OverviewEarly detection of biological threats, such as invasive species, increases the likelihood that control efforts will be successful and cost-effective. Environmental deoxyribonucleic acid (eDNA) sampling is an established method for the efficient and sensitive early detection of new biological threats. The Rapid eDNA Assessment and Deployment Initiative & Network (READI-Net) is a project des

Zebra and Quagga mussels in the United States—Dreissenid mussel research by the U.S. Geological Survey

The U.S. Geological Survey (USGS) delivers high-quality data, technologies, and decision-support tools to help managers both reduce existing populations and control the spread of dreissenid mussels. The USGS researches ecology, biology, risk assessment, and early detection and rapid response methods; provides decision support; and develops and tests control measures.

Expanding Distribution of Chronic Wasting Disease

Chronic wasting disease (CWD) has been detected in 35 US states and five Canadian provinces in free-ranging cervids and/or commercial captive cervid facilities. CWD has been detected in free-ranging cervids in 35 states and four provinces and in captive cervid facilities in 19 states and three provinces.

Cyanobacterial Harmful Algal Blooms in Central Park, New York

Cyanobacterial harmful algal blooms (cyanoHABs) can produce cyanotoxins that pose health risks to humans, pets, and wildlife that use freshwater lakes and ponds. While not often used for swimming or drinking water, human and animal contact with urban lakes can include boating, fishing, or use of shoreline walking paths. CyanoHABs are a persistent, annually recurring problem in several Central Park...

Invasive Species We Study: Invasive Carp

Bighead, black, grass, and silver carp, which are native to China, were originally stocked in aquaculture facilities to control algae, snails, and vegetation. These species escaped during flood events and are now established throughout the lower and middle Mississippi River Basins and some of its large tributaries where they damage ecosystems and harm economies. Grass carp are also reproducing in...
