Long Term Research in Environmental Biology Grant

LTREB fits eligible U.S. institutions and qualifying U.S.-located nonprofit research or educational organizations proposing extended environmental-biology time series that address important evolutionary biology, ecology, or ecosystem-science questions. Initial proposals seek five years of support within a decadal project concept and must use a 15-page project description containing a decadal research plan and core-data description. Fit depends on alignment with Ecosystem Science, Population and Community Ecology, or Evolutionary Processes; ecological marine research is excluded, while marine evolutionary-dynamics research is accepted. Confirm the active solicitation, deadline, detailed review criteria, and organizational eligibility before committing to an application.

Plain-English explanation

LTREB fits eligible U.S. institutions and qualifying U.S.-located nonprofit research or educational organizations proposing extended environmental-biology time series that address important evolutionary biology, ecology, or ecosystem-science questions. Initial proposals seek five years of support within a decadal project concept and must use a 15-page project description containing a decadal research plan and core-data description. Fit depends on alignment with Ecosystem Science, Population and Community Ecology, or Evolutionary Processes; ecological marine research is excluded, while marine evolutionary-dynamics research is accepted. Confirm the active solicitation, deadline, detailed review criteria, and organizational eligibility before committing to an application.

Editorial analysis

What the funder is trying to accomplish

NSF intends LTREB to support decadal projects that generate extended time-series data addressing important questions in evolutionary biology, ecology, or ecosystem science. For initial five-year support, proposals must include a decadal research plan and a description of core data.

Editorial analysis

Strong-fit project signals

The project will generate extended time-series data to answer an important question in evolutionary biology, ecology, or ecosystem science. The research clearly falls within Ecosystem Science, Population and Community Ecology, or Evolutionary Processes, the three Division of Environmental Biology clusters that process LTREB proposals. The science addresses a stated long-timescale example, such as evolutionary processes, time-varying interspecific interactions, dynamics of long-lived organisms, ecology-evolution feedbacks, slowly turning-over nutrient pools, or long-return-interval climatic cycles. For an initial proposal, the team can provide the required 15-page project description with both a decadal research plan and a description of core data. The applicant is an eligible U.S. IHE or qualifying U.S.-located nonprofit organization of the types specified in the notice.

Editorial analysis

What reviewers may prioritize

The specific LTREB review criteria are referenced but not reproduced in the evidence packet. It is therefore not possible to confirm reviewer criteria. It is reasonably inferred that a competitive proposal should make the importance of the long-term question, need for extended time-series data, decadal plan, core data, and fit with a named Environmental Biology cluster clear, because these elements are central to the program description and required proposal structure.

Source-backed synopsis

What this grant funds

The Long Term Research in Environmental Biology (LTREB) Program supports the generation of extended time series of data to address important questions in evolutionary biology, ecology, and ecosystem science. Research areas include, but are not limited to, the effects of natural selection or other evolutionary processes on populations, communities, or ecosystems; the effects of interspecific interactions that vary over time and space; population or community dynamics for organisms that have extended life spans and long turnover times; feedbacks between ecological and evolutionary processes; pools of materials such as nutrients in soils that turn over at intermediate to longer time scales; and external forcing functions such as climatic cycles that operate over long return intervals.

All proposals submitted through the LTREB solicitation are processed by 1 of the 3 clusters in the Division of Environmental Biology: Ecosystem Science, Population and Community Ecology, and Evolutionary Processes. Proposals must address topics supported by these clusters. Researchers who are uncertain about the suitability of their project for the LTREB Program are encouraged to contact the cognizant Program Officer.

Ecological research on marine populations, communities and ecosystems is not supported by LTREB and should be directed to the Biological Oceanography Program: ( https://www.nsf.gov/funding/opportunities/biooce-biological-oceanography ). However, research that examines the evolutionary dynamics of marine populations or communities will be accepted. Investigators who are uncertain about the suitability of their research for LTREB are strongly encouraged to contact the managing Program Officers listed in this solicitation.

Examples of current LTREB awards can be viewed at https://www.nsf.gov/awardsearch/ by including 'LTREB' in a title search.

The Program intends to support decadal projects. Funding for an initial, 5-year period requires submission of a proposal that includes a 15-page project description containingtwo essential components: a decadal research plan and a description of core data. Proposals for the second five years of support (renewal proposals) are limited to a ten-page project description.

Continuation of an LTREB project beyond an initial ten-year award will require submission of a new proposal that presents a new decadal research plan.

Specific review criteria for LTREB proposals and renewals are explained within this solicitation. Prospective proposers are advised to read this solicitation carefully.
