Opportunity Summary:

The U.S. Geological Survey (USGS) issued a discretionary research funding opportunity under the Cooperative Ecosystem Studies Unit (CESU) Program, specifically through the Great Rivers CESU. The project is offered as a cooperative agreement, which typically means USGS expects to have substantial involvement during the project period (for example, coordination on study design, oversight of technical approaches, data sharing, and review of deliverables), rather than simply providing funds with minimal interaction. The scientific focus of this opportunity is chronic toxicity testing involving metals, with the work centered on zinc or nickel exposure in mayflies. Mayflies are widely used in freshwater ecotoxicology because they are common aquatic insects, sensitive to water quality changes, and ecologically important as part of stream food webs, making them useful indicators for understanding how contaminants may affect aquatic ecosystems over time.

The intent of the work is to generate research data on longer-term (chronic) effects of zinc or nickel on mayflies, as opposed to only short-term (acute) lethality tests. Chronic toxicity studies generally look at endpoints such as survival over extended exposure periods, growth, development, emergence, and sometimes reproduction-related measures depending on the organism and test design. For metals like zinc and nickel, chronic effects can occur at concentrations below those that cause immediate death, and results are often used to refine water quality criteria, interpret field monitoring results, and improve ecological risk assessments. By targeting mayflies, the study supports understanding of how these metals may influence sensitive aquatic insect populations and, by extension, the broader health and function of freshwater systems.

Eligibility is limited to organizations that are already participating partners in the Great Rivers CESU network. CESUs are structured partnerships designed to streamline collaboration between federal agencies and partner institutions (often universities, research institutions, nonprofits, and sometimes state agencies) to provide research, technical assistance, and education. In this case, the listing makes clear that only Great Rivers CESU partners can apply, which is why the eligibility category is shown broadly as "Others" but clarified in the eligibility text. There is no cost sharing or matching requirement, meaning applicants are not required to provide additional non-federal funds to be considered.

From a funding and administrative standpoint, USGS anticipated making one award, with an estimated total funding amount of $94,000. The notice lists no formal award ceiling or floor (both shown as zero), which usually indicates the agency did not set fixed bounds in the public summary and instead expected the final award amount to be determined through the proposal and negotiation process, up to the estimated total available. The opportunity falls under the Science and Technology and other Research and Development activity category, and is associated with CFDA number 15.808, U.S. Geological Survey Research and Data Collection, which is a common federal assistance listing for USGS research-focused awards.

The opportunity was posted and created on May 26, 2015, with an original and current closing date of June 12, 2015, indicating a relatively short application window. The archive date is August 26, 2015, meaning it was later moved into an archived status on Grants.gov after the competition period ended. Applicants seeking the full announcement details were directed to Grants.gov via the additional information link, and the listed point of contact for assistance was Faith Graves at USGS (phone 703-648-7356, email fgraves@usgs.gov), particularly for issues accessing the announcement electronically.

In practical terms, this grant opportunity supported a targeted, applied research effort that would help USGS and partners improve the scientific basis for evaluating chronic metal toxicity in freshwater environments. Data from well-designed chronic tests with sensitive taxa like mayflies can feed directly into environmental management decisions, including setting or revising protective thresholds, interpreting biological monitoring responses, and understanding how metal exposures could alter aquatic communities over time.

Frequently Asked Questions (FAQs)

What is this funding opportunity?

This is a U.S. Geological Survey (USGS) discretionary research funding opportunity offered under the Cooperative Ecosystem Studies Unit (CESU) Program through the Great Rivers CESU. The award mechanism is a cooperative agreement.

Which USGS program is sponsoring the opportunity?

The opportunity is issued through the CESU Program, specifically the Great Rivers CESU network.

What type of award is being offered?

The project is offered as a cooperative agreement, meaning USGS typically expects substantial involvement during the project period rather than providing funds with minimal interaction.

What does "substantial involvement" by USGS typically include?

Based on the opportunity description, substantial involvement may include coordination on study design, oversight of technical approaches, data sharing, and review of deliverables.

What is the scientific focus of the project?

The focus is chronic toxicity testing involving metals, centered on zinc or nickel exposure in mayflies.

Which contaminants are the study centered on?

The work is centered on zinc or nickel.

Which organism is the study focused on?

The study is focused on mayflies, which are commonly used in freshwater ecotoxicology.

Why are mayflies used in freshwater ecotoxicology?

Mayflies are common aquatic insects, sensitive to water quality changes, and ecologically important in stream food webs. Because of these traits, they are often used as indicators for understanding how contaminants may affect aquatic ecosystems over time.

What is the intent of the research?

The intent is to generate research data on longer-term (chronic) effects of zinc or nickel on mayflies, rather than focusing only on short-term (acute) lethality tests.

What is the difference between chronic and acute toxicity testing in this context?

Acute testing generally examines short-term effects such as immediate lethality, while chronic toxicity studies examine longer-term effects over extended exposure periods, including outcomes that can occur at concentrations below those that cause immediate death.

What endpoints are typically evaluated in chronic toxicity studies?

Chronic toxicity studies generally look at endpoints such as survival over extended exposure periods, growth, development, and emergence. In some cases, they may also include reproduction-related measures depending on the organism and test design.

Why focus on chronic effects of zinc or nickel?

For metals like zinc and nickel, chronic effects can occur at concentrations below those that cause immediate death. Chronic data can help improve the scientific basis for interpreting long-term ecological impacts.

How might the results of this research be used?

The description indicates results are often used to refine water quality criteria, interpret field monitoring results, and improve ecological risk assessments. Data may also support environmental management decisions such as setting or revising protective thresholds and understanding how metal exposures could alter aquatic communities over time.

What broader environmental value does a mayfly-focused study provide?

Because mayflies are sensitive and ecologically important, the study supports understanding of how zinc or nickel may influence sensitive aquatic insect populations and, by extension, the broader health and function of freshwater systems.

Who is eligible to apply?

Eligibility is limited to organizations that are already participating partners in the Great Rivers CESU network.

Are non-CESU organizations eligible if they have relevant expertise?

The opportunity text specifies that only Great Rivers CESU partners can apply.
