Effects of Early Life Stage Exposure of Largemouth Bass to Atrazine or a Model Estrogen (17α-Ethinylestradiol)
Early development is a sensitive window for estrogenic endocrine disruption in largemouth bass. Atrazine treatments caused changes to gene expression patterns that were both similar to estrogen and distinct from estrogen.
Physical Stream Dynamics and Native Mussel Habitats
Freshwater mussel conservation efforts depend on identifying habitat characteristics that are suitable for mussel reintroduction and restoration. CERC scientists are conducting research to understand how physical habitat dynamics affect the distribution of mussels and suitable habitat in streams and rivers.
Exploring the Potential for Conservation Lands in Middle Mississippi River Floodplains to Mitigate Flood Flows for Ecosystem Services
Reconnection of floodplains to their rivers has been considered a fundamentally beneficial ecological practice.
Molecular Section: eDNA Research
Environmental DNA (eDNA) research at CERC focuses on the development and utility of eDNA tools as well as interpretation of eDNA data in real-world management applications. We work with academic, state, federal and international partners in developing standards and best practices for eDNA technology and exploring the factors that affect eDNA detection in the field. Our lab's eDNA research covers...
Thiamine (Vitamin B1) Deficiency in Fish and Wildlife
In the last few decades, thiamine deficiency has been observed in fish and wildlife in the Great Lakes, Alaska, Sweden and several other areas in North America and Europe. Thiamine is an essential vitamin needed for cell function. Thiamine deficiency has been linked to neurological disorders, immunosuppression, and lower reproductive viability. These disorders potentially reduce populations of...
Adult Pallid Sturgeon Reproductive Ecology
CERC fish biologists study migrations, reproductive cues, and spawning behaviors of reproductive wild and hatchery-origin pallid sturgeon (HOPS) in the Missouri River Basin.
Missouri River Recovery Implementation Committee (MRRIC) and Adaptive Management
This project centers on assimilation of data, interpretation of results, updating quantitative models, and providing policy-neutral, high-quality information to the agencies and stakeholders in the Missouri River Basin.
Pallid Sturgeon Early Life
CERC biologists focus on improving understanding of biomechanics of eggs, free embryos, and larvae through direct observation and measurement. An improved understanding of biomechanics – how biotic conditions and processes interact with physical processes to result in changes in survival – is necessary to create quantitative links between management actions and population-level results.
Development and Evaluation of Novel Capture Gears for Bigheaded Carps
Mass removal of Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis , hereafter referred to as bigheaded carps, is a primary management action to contain the population growth and reduce upstream dispersal. The use of passive trap nets to harvest bigheaded carps may effectively supplement active capture techniques. The USGS is working with partner agencies to...
Chemical Attractant Investigations to Increase Aggregation and Harvest for the Control of Asian Carp
Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis , hereafter referred to as bigheaded carps, are rapidly expanding their range. Federal agencies and the Illinois Department of Natural Resources are focused on keeping invasive carps out of the Great Lakes. The development of an effective attractant may assist managers with capturing carps in low-density areas such...
Assessment of Acoustic Stimuli for Manipulating Movement of Bigheaded Carps
Invasive Silver Carp Hypophthalmichthys molitrix and Bighead Carp Hypophthalmichthys nobilis , hereafter referred to as bigheaded carps, have displayed a negative phonotactic response when presented with a broadband acoustic stimulus. Additional study is needed to identify effective acoustic stimuli for manipulating bigheaded carp behavior, and to test bigheaded carp responses to those stimuli in...
River-Corridor Habitat Dynamics
River-Corridor Habitat Dynamics research seeks to improve the scientific basis for ecological restoration of large rivers. Emphasis is placed on understanding how hydrologic and geomorphic characteristics combine to create dynamic habitats for native and exotic fauna and flora.
