Invertebrates
Invertebrates
Invertebrates are those animals lacking a vertebral column, also known as a spine. Invertebrate species include insects, mollusks (e.g., snails and bivalves), crustaceans (e.g., shrimp and crabs), cnidarians (e.g., anemones and corals), and echinoderms (e.g., starfish). WARC conducts research on invertebrates found on land – including pollinator species like bees and butterflies – and in the water – like deep-sea corals.

Lower Trophic Level Monitoring to Support Restoration of Living Resources in Barataria Estuary, Louisiana
USGS researchers are collecting information about lower trophic levels in Barataria Estuary to develop a long-term monitoring plan.
Characterization of Benthic Habitats on the Pacific Margin: Assessing the Connectivity of Hard Substrates, Seeps and Canyon Communities
USGS researchers will characterize the ecology of benthic invertebrates associated with deep-sea environments and broader food-web dynamics within hardground features, seeps, and adjacent soft sediments. This project will provide important information regarding deepwater benthic habitats, such as chemosynthetic communities and deep-sea corals, that could be affected by offshore wind development.
USGS National Vision for Native Freshwater Mussel Research: Completing a Bureau-wide Ecosystems Mission Area-led Science Strategy
USGS is collaborating with partners to develop a scientific vision for freshwater Mussel research.
Nekton References and Targets: Assessing the Abundance and Density of Fish and Invertebrates Associated with Louisiana’s Marsh Habitat
The National Oceanic and Atmospheric Administration (NOAA) is leading a Monitoring and Adaptive Management (MAM) activity with USGS collaborators to establish reference ranges and restoration targets, assess data gaps for focal nekton species and/or guilds associated with Louisiana’s estuarine and coastal habitats, implement the fixed-area sampling strategy to quantify fishes and invertebrates...
Puget Sound Marine Benthic Index and Graphical Causal Model
USGS scientists are working with partners at the Puget Sound Partnership and the State of Washington’s Department of Ecology to develop two new tools to help us understand how human disturbance affects life at the top of Puget Sound: a Marine Benthic Index and a graphical causal model.
Development and Implementation of Environmental DNA (eDNA) Tools to Aid Listing and Recovery Efforts for Imperiled and Common Freshwater Mussels
Researchers will develop and optimize an eDNA assay to delineate the current distribution of P. inflatus . The assay will then be used to provide up-to-date distributional information and detection rates for P. inflatus in the Pearl River basin.
Survey and Assessment of Live Food Markets as an Invasion Pathway
Live food markets may be a source of the increasing number of non-native wild invertebrate and fish species, like Asian swamp eels and snakeheads. USGS is surveying such markets around the United States to identify and document species that might be of concern if released live into the wild to assess if the live food market is a possible invasion pathway.
Risk Analysis of Invasive Freshwater Fishes in Hawaii and Micronesia
Invasive species threaten biodiversity around the world, especially on islands. USGS scientists are helping to identify fish species that have the greatest potential to invade the fresh waters of Microneisa.
The Oysters of Chicopit: Status of the Oyster Population in Chicopit Bay before, during, and after the Construction of the Mile Point Project
Chicopit Bay, part of the Timucuan Ecological and Historic Preserve in Florida, is a small embayment at the intersection of San Pablo Creek (part of the Intercoastal Waterway) and the St. Johns River. Home to a number of small oyster beds, this area is now being dredged to help eliminate cross currents from the main shipping channel of the St. Johns. WARC researchers collect baseline environmental...
American Fisheries Society List of Freshwater Snails from Canada and the United States
This website provides access to the list of freshwater gastropods (snails) in Canada and the United States as determined by the 2013 American Fisheries Society (AFS) Endangered Species Committee (ESC) on freshwater gastropods.
American Fisheries Society Crayfish of the United States and Canada
This website provides access to the list of crayfish in Canada and the United States as determined by the 2007 American Fisheries Society (AFS) Endangered Species Committee (ESC) on Crayfishes.
Coral Bleaching and Disease: Effects on Threatened Corals and Reefs
A severe disease - tentatively named stony coral tissue loss disease - is rapidly killing corals in the U.S. Virgin Islands. Scientists from the U.S. Geological Survey, the University of Puerto Rico, and the National Park Service are working together to better under the disease and determine if the disease affecting corals in the USVI is the same one that has been killing corals in Florida since...
