This $690,185 project grant from the National Science Foundation's (NSF) Polar Programs will fund research to better understand the extinction of giant ice age mammals in Alaska around the end of the last ice age. The University of Alaska Fairbanks will lead the collaborative research effort to extract and analyze ancient DNA preserved in frozen ground where ice age mammals like woolly mammoths and steppe bison once lived. Researchers will identify the species the DNA belonged to and date the...
The National Science Foundation Division of Polar Programs awarded a $294,004 Project Grant to the University of California Santa Cruz under the Polar Programs federal grant program (CFDA 47.078) to conduct collaborative research on the extinct megafauna of Alaska from June 1, 2022 to May 31, 2025. The research aims to pinpoint the precise extinction dates of the last mammoth, steppe bison, and tundra lion in Alaska through extracting and analyzing ancient DNA preserved in frozen soil, in...
The National Science Foundation's Polar Research (NSPR) Program has awarded a $804,507 project grant to the University of Alaska Fairbanks (UAF) to fund the scientific analysis of materials recovered from the Broken Mammoth archaeological site in central Alaska. This 3-year grant aims to reconstruct human subsistence economies, technological organization, and site structure at this key early Beringian site, which has yielded a vast collection of artifacts and butchered animal bones. Through...
The National Science Foundation (NSF) awarded a $126,959 Project Grant under the Polar Research (NSPR) program to the University of Arizona, doing business as the Arizona Board of Regents. This grant, awarded on October 1, 2023, will fund the scientific analysis of materials recovered from the Broken Mammoth archaeological site in central Alaska. The research team will curate and analyze the site's large collection of artifacts, butchered animal bones, and environmental samples to reconstruct...
The National Science Foundation Division of Polar Programs has awarded a $499,527 Project Grant to the University of Wyoming, Sponsored Programs to conduct research on reconstructing subsistence, diet breadth, and paleoclimate in Interior Alaska during social and climatic transitions. The project will analyze isotopic and molecular data from over fifty legacy collections and experimental cooking features to refine reconstructions of past subsistence practices. Targeted archaeological excavations...
This $112,243 Project Grant award from the National Science Foundation's (NSF) Mathematical and Physical Sciences program (CFDA 47.049) supports a collaborative research project between the University of California - Merced and the University of Alaska Fairbanks. The project aims to reconstruct and analyze the dynamics of historical and paleo-ecosystems, with a focus on understanding how marine communities have responded to climate change and resource exploitation over time, particularly...
The National Science Foundation (NSF) awarded a $798,000 Project Grant under the Biological Sciences program (CFDA 47.074) to the University of New Mexico (UNM) for a 3-year research project entitled "The New Normal: The Continuing Influence of the Late Pleistocene Megafauna Extinction on the Structure and Function of Mammal Communities." The project aims to quantify the ecological legacy of the extinction of large mammals such as mammoths, llamas, and saber-toothed cats in the...
The University of Massachusetts was awarded a two-year, $285,631 Project Grant from the National Science Foundation Division of Polar Programs to assess the relationship among fire, temperature, and precipitation in the Arctic during the Pleistocene period. The grant will fund research best conducted under the NSF's Polar Programs, which provides support to strengthen understanding of polar regions through expanded fundamental knowledge. The University will analyze how fire, temperature, and...
This $335,777 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will support research by Brown University to investigate the impacts of climate change on northern mountain woodland caribou in the Arctic. The research will leverage both modern GPS tracking data and paleontological evidence from caribou dung preserved in ice patches to study how caribou diet and habitat use have shifted in response to climatic changes over the Holocene period. Key objectives...
This National Science Foundation (NSF) Division of Polar Programs Project Grant award to Northern Arizona University totals $319,829 over 5 years from September 1, 2023 to August 31, 2028. The project, titled "The Arctic Carbon and Climate (ACClimate) Observatory: Tundra Ecosystem Carbon Balance and Old Carbon Loss as a Consequence of Permafrost Degradation," will examine the dynamics of permafrost carbon, which stores substantial quantities of carbon in Arctic soils, and the impact of...
