Ozarks Stream Dynamics and Native Mussel Habitats

The National Park Service is implementing plans for the survey and management of the mussel fauna at the Ozark National Scenic Riverways and Buffalo National River in Missouri. CERC scientists are conducting research to understand how geomorphic patterns effect the distribution of mussels in Missouri streams.

Validation of Zinc and Nickel Biotic Ligand Models Based on Toxicity Testing in Natural Waters with Ceriodaphina dubia

Most states use outdated hardness-based criteria to regulate metals in surface waters. The slow adoption of new criteria based on biotic ligand models (BLMs) reflects uncertainty about whether these models can reliably predict toxic effects of metals on aquatic biota across the wide range of water quality conditions affecting bioavailability.

An Evaluation the Chronic Toxicity of Metals in Water and Sediment to the Unionid Mussel, Fatmucket (Lampsilis siliquoidea), in Exposures Representing Conditions in the Tri-States Mining District

The Tri-State Mining District (TSMD) is a large (about 500 sq. mi.) historical lead and zinc mining area that includes portions of Kansas, Missouri and Oklahoma. The TSMD yielded about 460 million tons of ore between 1885 and 1970, resulting in contamination of surface water, groundwater, sediments, and soils in the Spring River and Neosho River basins by lead, zinc, and other heavy metals.

An assessment of Deep Fork River Effluent Toxicity to the Unionid Mussel Fatmucket (Lampsilis siliquoidea)

Nearly 70% of the 300 mussel species in North America are endangered, threatened, of special concern, or extinct. Environmental contaminants have been identified as a contributing factor to the decline of mussel populations.

High Resolution Vegetation Mapping at Palmyra Atoll Using Unoccupied Aerial Systems (UAS)-Acquired Imagery

Lying 1000 miles south of Hawaii, Palmyra Atoll is a marine wilderness co-managed by the US Fish and Wildlife Service and The Nature Conservancy. Beach forests of Pisonia grandis and other vegetation communities provide habitat for thousands of nesting terns, boobies, and other birds. Introduced coconut (Cocos nucifera) groves and use of Palmyra as a World War II airfield left a legacy of invasive...

Black Carp Biology, Status, and Selective Toxic Bait Development

Black Carp (Mylopharyngodon piceus) is the largest of the four non-indigenous carp species, reaching sizes well in excess of 100 pounds. CERC scientists, in cooperation with federal and state partners, are studying the biology of black carp and developing tools to control the spread of this non-indigenous species.

Restoration Planning, Implementation, and Monitoring: Invasive Species Eradication and Control Program at the Little Saint Francis River Chat Pile

Among sites undergoing restoration activities as part of the Southeast Missouri Mining District (SEMO) Natural Resource Damage Assessment and Restoration settlement, the Little St. Francis River Chat Pile (LSFR) will be one the first in Madison County at which primary ecological restoration will be implemented. CERC scientists are collaborating with the US Fish and Wildlife Service and the...

Early Life History of Bighead, Silver, Black, and Grass Carps

Grass, bighead, black, and silver carps spawn in turbulent rivers and their eggs develop and hatch while drifting downriver. The larvae also have a short period of developing in the drift, and then they must swim from the river and find appropriate low- or no-flow nursery areas. Rivers which are not long enough, turbulent enough, or without nursery areas in the correct locations are not likely to...

Fire and Climate Suitability for Woody Vegetation Communities in the South Central United States

Climate and fire are global drivers of plant species distributions in the south central United States. Long-term management of vegetation communities can benefit from information on projected spatial changes in climate and fire frequencies.

Floodplain Processes and Habitats

Tools to quantify and predict benefits of floodplain connectivity are lacking, diminishing the ability of managers and stakeholders to assess present and future ecological benefits. In particular, tools are needed to evaluate the duration, seasonality, extent, and magnitude of inundation on floodplains under present conditions. Furthermore, tools are needed to allow for translating inundation into...
