Opportunity Summary:
The Cooperative Ecosystem Studies Unit, South Florida CESU grant opportunity (Funding Opportunity Number 10HQPA0042) is a U.S. Geological Survey (USGS) cooperative agreement intended to fund a focused research task that supports restoration planning and scenario evaluation for the Greater Everglades Ecosystem. The project centers on using geochemical evidence preserved in soils to reconstruct how vegetation and hydrologic conditions in Everglades marl prairies have changed over time, information that can help decision-makers understand past ecosystem states and better evaluate restoration strategies.
The core scientific work involves analyzing carbon isotopic signatures in soil organic matter (SOM) taken from sediment cores collected across marl prairie locations throughout the Greater Everglades. The main objective is to measure stable carbon isotopes (reported as delta 13C values) for an estimated 105 samples derived from these cores. This approach relies on the well-established relationship between plant photosynthetic pathways and carbon isotope ratios: C3 plants and C4 plants have distinct isotope signatures, and in marl prairie wetlands the relative abundance of C3 vegetation is positively associated with longer hydroperiods (wetter conditions). Because of that linkage, shifts in SOM delta 13C values can be interpreted largely as changes in the proportion of C3 versus C4 plant inputs over time, which in turn reflects hydrologic shifts affecting the wetland.
The opportunity also highlights that isotope measurements are not meant to stand alone. The same samples (or closely aligned core intervals) are examined with additional environmental proxies, especially pollen and charcoal. Pollen provides direct evidence of plant community composition through time, while charcoal helps indicate fire history and burning intensity or frequency. To place all of these signals on a timeline, the study uses multiple dating and stratigraphic tools, including radiocarbon dating, lead-210 analysis, cesium-137 analysis, and pollen biostratigraphy, which together are used to build age models for the sediment cores. The end product is an integrated reconstruction that identifies intervals of vegetation change and ties those transitions to changing hydrologic conditions, with particular attention to the development and evolution of marl prairie plant communities.
Administratively, this is a discretionary funding opportunity using a cooperative agreement instrument under the Science and Technology and other Research and Development activity category. The program is issued under the Cooperative Ecosystem Studies Unit (CESU) framework, meaning eligibility is limited to organizations that are official participating partners in the South Florida CESU Program. The listing is associated with CFDA number 15.808 (U.S. Geological Survey Research and Data Collection). The announcement indicates no cost sharing or matching requirement. The estimated total funding for the award is $15,000, with an expected number of awards listed as one. The posting and creation date were March 8, 2010, with a closing date of March 17, 2010, and an archive date of April 16, 2010.

Frequently Asked Questions (FAQs)
What is this grant opportunity?
This is a U.S. Geological Survey (USGS) Cooperative Ecosystem Studies Unit (CESU) funding opportunity for the South Florida CESU Program. It is issued as a cooperative agreement and is intended to support a focused research task tied to restoration planning and scenario evaluation for the Greater Everglades Ecosystem.
What is the Funding Opportunity Number?
The Funding Opportunity Number is 10HQPA0042.
Which agency is offering the award?
The opportunity is offered by the U.S. Geological Survey (USGS).
What type of funding instrument is being used?
The award is issued as a cooperative agreement.
Is this a discretionary funding opportunity?
Yes. The announcement describes it as a discretionary funding opportunity.
What program framework does this opportunity fall under?
It is issued under the Cooperative Ecosystem Studies Unit (CESU) framework, specifically the South Florida CESU Program.
Who is eligible to apply?
Eligibility is limited to organizations that are official participating partners in the South Florida CESU Program.
What is the activity category for this opportunity?
The activity category is Science and Technology and other Research and Development.
What is the CFDA number associated with this listing?
The listing is associated with CFDA 15.808 (U.S. Geological Survey Research and Data Collection).
What is the main purpose of the project?
The project is intended to support restoration planning and scenario evaluation for the Greater Everglades Ecosystem by reconstructing how vegetation and hydrologic conditions in Everglades marl prairies have changed over time using geochemical evidence preserved in soils.
What ecosystem or region does the project focus on?
The work focuses on marl prairie locations across the Greater Everglades and is intended to inform decisions for the Greater Everglades Ecosystem.
What are “marl prairies” in the context of this project?
In this opportunity, marl prairies are wetland areas within the Everglades where soil (including sediment cores) can preserve geochemical and biological evidence used to infer past vegetation and hydrologic conditions.
What is the core scientific analysis described in the announcement?
The core work is the analysis of carbon isotopic signatures in soil organic matter (SOM) taken from sediment cores collected across marl prairie sites.
What specific isotope measurements are being made?
The project measures stable carbon isotopes reported as delta 13C (d13C) values in soil organic matter (SOM).
How many samples are expected to be analyzed?
The announcement estimates approximately 105 samples derived from the sediment cores.
Why are carbon isotopes useful for reconstructing vegetation change?
The opportunity relies on the established relationship between plant photosynthetic pathways and carbon isotope ratios. C3 and C4 plants have distinct isotope signatures, so changes in SOM d13C values can be interpreted as shifts in the relative contribution of C3 versus C4 plant inputs over time.
How does the project connect vegetation changes to hydrologic conditions?
In marl prairie wetlands, the relative abundance of C3 vegetation is described as positively associated with longer hydroperiods (wetter conditions). Because of that linkage, inferred shifts between C3 and C4 inputs (from SOM d13C values) are used to interpret hydrologic shifts over time.
Are isotope measurements the only data used in the reconstruction?
No. The announcement states that isotope measurements are not intended to stand alone and should be interpreted alongside other environmental proxies.
What additional environmental proxies are included?
The opportunity specifically highlights pollen and charcoal as additional proxies examined on the same samples (or closely aligned core intervals).
What does pollen analysis contribute to the study?
Pollen provides direct evidence of plant community composition through time.
What does charcoal analysis contribute to the study?
Charcoal helps indicate fire history, including burning intensity or frequency.
How are the sediment cores dated or placed on a timeline?
The study uses multiple dating and stratigraphic tools to build age models for the sediment cores, including radiocarbon dating, lead-210 analysis, cesium-137 analysis, and pollen biostratigraphy.
What is the intended end product of the research?
The end product is an integrated reconstruction that identifies intervals of vegetation change and ties those transitions to changing hydrologic conditions, with particular attention to the development and evolution of marl prairie plant communities.
What is the estimated total funding amount?
The estimated total funding for the award is $15,000.
How many awards are expected?
The expected number of awards is one.
Is cost sharing or matching required?
No. The announcement indicates there is no cost sharing or matching requirement.
What are the key dates for this opportunity?
Posting/creation date: March 8, 2010. Closing date: March 17, 2010. Archive date: April 16, 2010.
Who is the contact for access issues or administrative questions?
The contact listed is Faith Graves, Contract Specialist.
