Project Grant 1754713

This National Science Foundation Project Grant of $184,289 supports research at Texas A&M Agrilife Research to advance understanding of how iron impacts the temperature sensitivity of heterotrophic respiration in humid tropical soils. The award period is from May 1, 2023 through April 30, 2026. The research leverages experiments and process-based modeling at the Tropical Responses to Altered Climate Experiment in Puerto Rico's Luquillo Rainforest. Comprehensive experiments with soils sampled...

The National Science Foundation Division of Environmental Biology awarded $188,656 under the Biological Sciences (CFDA 47.074) federal grant program to the University of Georgia Research Foundation from May 1, 2023 to April 30, 2026. This Project Grant will support collaborative research evaluating how iron cycling impacts the temperature sensitivity of heterotrophic respiration in humid tropical soils over time. The research combines field experiments leveraging the Tropical Responses to...

This $861,035 Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) supports research into how mature trees in the Amazon rainforest are adapting to rising temperatures. Researchers at the University of Miami will conduct field studies around Peru's "Boiling River", a unique geothermal area that mimics the predicted future temperature conditions for much of the Amazon. The key objectives are to 1) map the environmental conditions in...

This three-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $586,098 to Texas A&M University to conduct research reconstructing ancient ocean temperatures during the Devonian-Mississippian climate transition. The university will test whether tropical ocean temperatures reached extremely high levels of 95-104 degrees Fahrenheit during the time of early animals. It will examine the role of rapid cooling in triggering biotic crises and explore...

This $908,131 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), supports research to better understand how changing phytoplankton elemental use efficiencies may impact global ocean biogeochemistry as temperatures rise. A team of U.S. and U.K. researchers, led by the University of Southern California, will conduct laboratory experiments and field work to quantify the effects of temperature on nutrient elemental use...

This NSF Integrative Activities (CFDA 47.083) Project Grant award to Brown University provides $270,794 to support research on the role of deep ocean equilibration in warmer climates. The project aims to: Perform long-running climate model simulations (over 6,000 years) to better understand the equilibrium responses of the deep ocean under elevated CO2 conditions, as seen during the Middle Miocene Climate Optimum around 15 million years ago. Compare the simulated Miocene ocean conditions with...

This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $248,863 to the Massachusetts Institute of Technology for research entitled "Collaborative Research: Ear Climate - Pairing Calcium and Clumped Isotopes to Inform Carbon Cycle and Climate Dynamics at the Onset of the Late Paleozoic Ice Age." The research will develop novel isotope proxies to understand the role of land plant evolution on organic carbon burial, atmospheric carbon dioxide,...

This $172,778 project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund research to test climate model predictions of hydrologic change in the tropical Atlantic during a past warm period. Specifically, the awardee, Utah State University, will geochemically analyze oxygen isotopes and magnesium-to-calcium ratios in planktonic foraminifera from deep-sea sediment cores at several sites, including Ocean Drilling Project Site...

This Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences, under the Geosciences program (CFDA 47.050), will provide $417,242 to The Research Foundation for The State University of New York (RF-SUNY) from September 1, 2023 to August 31, 2026 to conduct collaborative research on the 50,000-year history of the Indian Summer Monsoon (ISM). The research will focus on analyzing sediment cores from Loktak Lake in northeast India to reconstruct past changes in the...

This Project Grant award from the National Science Foundation (NSF) Division of Integrative Organismal Systems, through the Biological Sciences program (CFDA 47.074), provides $693,856 to the University of California, Davis (UC Davis) to conduct research on the direct response of leaf stomata to temperature changes. The key objectives are to: 1) Quantify the direct stomatal response to temperature (DRST) and its acclimation to growth temperature across 60 plant species representing major...
