Long Term Research in Environmental Biology

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.

Eligibility

*Who May Submit Proposals: Proposals may only be submitted by the following: -Non-profit, non-academic organizations: Independent museums, observatories, research laboratories, professional societies and similar organizations located in the U.S. that are directly associated with educational or research activities. -Institutions of Higher Education (IHEs): Two- and four-year IHEs (including community colleges) accredited in, and having a campus located in the US, acting on behalf of their faculty members. Special Instructions for International Branch Campuses of US IHEs: If the proposal includes funding to be provided to an international branch campus of a US institution of higher education (including through use of sub-awards and consultant arrangements), the proposer must explain the benefit(s) to the project of performance at the international branch campus, and justify why the project activities cannot be performed at the US campus.

Geological Survey

Cooperative Agreement for Affiliated Partner with the Colorado Plateau Cooperative Ecosystem Studies Unit (CESU)

U.S. Geological Survey's (USGS), Northern Rocky Mountain Science Center (NOROCK), is offering a funding opportunity to improve assessments of floodplain connectivity and riverscape health. Current approaches to identify floodplain connectivity across the western United States rely on field data, limiting inference and spatial extent of data. However, existing lidar datasets through the USGS provide unique opportunities to develop approaches using lidar elevation data to provide robust estimates of floodplain connectivity. The ultimate use of these data would be to identify factors limiting healthy riverscapes across the Great Basin. The CESU partner in collaboration with NOROCK's research fisheries biologist will advance the ability to evaluate riverscape health by addressing one or more of the following considerations to improve assessments of riverscape health: Develop a workflow for using lidar to estimate floodplain connectivity within riverscapes in the Great Basin. Demonstrate the benefits this approach in comparison to existing methods. Quantify continuous estimates of floodplain connectivity across portions of the Great Basin. Results will be useful to the broader community working to assess and restore the health and ecosystem services of riverscapes in the Western US in relation to drought, land management activities, and fish and wildlife populations. Biologists and geomorphologists from NOROCK and the CESU Partner will collaborate with federal and state agencies and NGO partners to ensure their approach and data are accessible, scalable, and transferable to encourage the uptake by the broader scientific community involved with riverscape health assessments and restoration actions. This project focuses on using remote sensing products to efficiently direct resources to restoration of rivers and riparian areas. Using lidar data to map the health of riverscapes supports: SO 3435 - Implementation of the Expanding Public Lands Outdoor Recreation Experiences Act (June 25, 2025) SO 3442 - Land and Water Conservation Fund Implementation by the U.S. Department of the Interior (September 4, 2025) Improving methods beyond field data by leveraging available lidar data will provide continuous, robust measures of riverscape health, thus supporting and restoring Gold Standard Science approaches: EO 14303 – Restoring Gold Standard Science (May 23, 2025) SO 3441 Implementing the Requirements of Executive Order 14303, Restoring Gold Standard Science, May 23, 2025 (August 29, 2025) Restoring our riverscapes will inform Land and Water Conservation Fund Implementation by the U.S. Department of the Interior: and the lead to improved riverscape health that align with the Implementation of the Expanding Public Lands Outdoor Recreation Experiences Act. Further, the benefits of this project will provide cascading benefits to fish and wildlife, thus recovering populations and species. This falls in line with the goals outlined in: EO 14313 – Establishing the President's Make America Beautiful Again Commission (July 3, 2025) SO 3435 - Implementation of the Expanding Public Lands Outdoor Recreation Experiences Act (June 25, 2025) SO 3442 - Land and Water Conservation Fund Implementation by the U.S. Department of the Interior (September 4, 2025)
