Project Grant 2503762
- This Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) provides $472,614 to Cornell University from July 2022 through June 2026 to study the impacts of severe drought on tropical forest post-disturbance recovery. Specifically, the researchers are conducting a rainfall manipulation experiment in a forest in Puerto Rico that is recovering from Hurricane Maria in 2017. The project aims to characterize and predict forest resilience to climate change by...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project to characterize historical drought patterns in West Africa. The $303,519 award to Mississippi State University, with a performance period from September 1, 2024 to August 31, 2027, will fund the collection of tree-ring samples in Ghana and Senegal through annual field schools. The goal is to use these paleoclimate reconstructions to better understand the...
- This $211,743 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to reduce uncertainties in tree-ring records of wet extremes to aid interpretations of past climate and plan for future changes. The primary objectives are to: Use dendrometers to measure how tree growth responds to changes in precipitation frequency, intensity, and timing at sites in the AmeriFlux network. Reconstruct wet extremes of precipitation from previously collected tree-ring...
- The National Science Foundation Division of Environmental Biology awarded a $193,752 Project Grant to the Regents of the University of Minnesota under the Biological Sciences federal grant program (CFDA 47.074). The award will fund collaborative research from July 2022 through June 2026 to study the impacts of severe drought on tropical forest post-disturbance recovery in Puerto Rico. Specifically, researchers will conduct a rainfall manipulation experiment in a forest recovering from...
- The National Science Foundation (NSF) awarded a $192,386 Project Grant through its Geosciences program (CFDA 47.050) to the University of Arizona for a 3-year collaborative research project to reconstruct tropical rainfall patterns over the last 200 years. The project aims to use stable oxygen isotopes measured in tree ring cellulose from sites across Central and South America to study variations in the position and width of the Intertropical Convergence Zone and understand how these changes...
- This National Science Foundation Project Grant of $480,484 supports research to understand drought and post-drought legacy effects in tropical forests. Funded under the Biological Sciences program (CFDA 47.074), the University of California, Los Angeles will leverage a large-scale drought experiment in an Amazon forest in Brazil. Researchers will integrate high-resolution tower-based radar data measuring vegetation water content at finer scales than satellites. This will be compared with plant...
- This National Science Foundation Geosciences Program (CFDA 47.050) award of $258,917 to Northern Arizona University supports collaborative research to assess past and future droughts in the Colorado River Basin over the past 2,000 years. The project will extend tree-ring reconstructions of drought and combine them with other geological records to characterize the intensity and persistence of past droughts, including a potentially severe drought in the 2nd century. This research aims to inform...
- This $202,000 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support a research project to reconstruct past variations in vapor pressure deficit (VPD) in the southwestern United States over the last 500 years. The project will use oxygen isotope measurements in tree rings to develop long-term VPD reconstructions, which will then be compared to climate model simulations to assess the drivers of VPD changes and determine if the recent VPD...
- The National Science Foundation (NSF) awarded a $562,254 Project Grant under the Geosciences program (CFDA 47.050) to The Trustees of Columbia University in the City of New York. The purpose of this 3-year grant, with an award date of February 1, 2024, is to use stable oxygen isotopes measured in tree-ring cellulose across the tropical Americas to reconstruct wet season precipitation variability over the past 200 years. This research aims to gain insights into large-scale tropical climate...
- The National Science Foundation awarded a $2,010,368 Project Grant to Columbia University under the Biological Sciences federal grant program (CFDA 47.074) from July 1, 2022 to June 30, 2026. The grant funds collaborative research on the impacts of severe drought on tropical forest recovery after hurricanes. Researchers are conducting a large-scale rainfall manipulation experiment in a forest in Puerto Rico recovering from Hurricane Maria to characterize forest resilience to climate change. Nine...
This National Science Foundation (CFDA 47.050 - Geosciences) project grant, awarded to the University of Tennessee (with the Tennessee Agriculture Experiment Station as a sub-awardee), will reconstruct the long-term history of drought in the Caribbean using measurements of blue intensity of Hispaniolan pine trees. The $376,962 award, made on September 1, 2025, will also conduct climate model experiments to investigate the mechanisms driving multi-year drought in the region and estimate the risk of future drought. Broader impacts include supporting undergraduate and graduate student participation and a workshop on dendrochronology, data science, and modeling. The goal is to collect and analyze tree ring samples to understand past drought frequency, duration, and magnitude in the Caribbean, and use climate models to study the climatic drivers of these drought patterns.
