This three-year Project Grant from the National Science Foundation, worth $393,552, will fund collaborative research on comparative taphonomy and time-averaging of mollusk-echinoid assemblages using high-performance radiocarbon dating at the University of Florida from September 2021 through August 2024. The research aims to strengthen understanding of the integrated Earth system through basic research in the atmospheric, earth, and ocean sciences, as outlined in the Geosciences program (CFDA...
This Project Grant award, funded by the National Science Foundation's (NSF) Mathematical and Physical Sciences Program (CFDA 47.049), supports collaborative research between the University of California - Merced and the University of Alaska Fairbanks to reconstruct the dynamics of ancient marine ecosystems. The $112,243 award, spanning May 2025 to August 2027, aims to uncover how marine communities have responded to climate change and resource exploitation in the past, focusing on the...
The National Science Foundation Division of Ocean Sciences awarded a $272,065 Project Grant to the University of Alabama under the Geosciences federal grant program (CFDA 47.050) to support research on planktic foraminifera from October 1, 2022 to September 30, 2024. The grant will fund a study using electron backscatter diffraction and nanoscale secondary ion mass spectrometry to evaluate changes in biomineral structure, organic matter distribution, and relative nitrogen content of foraminifera...
The National Science Foundation's Geosciences program (CFDA 47.050) awarded a $296,303 Project Grant to the University of California, Berkeley to conduct research evaluating the development, stability, and evolution of shell gravel habitats along a latitudinal gradient on the Pacific coast of North America. The project aims to assess the coevolution of benthic invertebrate communities and shell gravel habitats, quantifying processes such as shell accumulation rates, community-substrate...
This Project Grant award of $457,737 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support collaborative research by the California Academy of Sciences to model marine paleocommunity dynamics across the Permian-Triassic mass extinction event 251 million years ago. The research aims to challenge uniformitarian assumptions in reconstructing ancient ecosystem food webs and test whether post-extinction communities functioned differently from those during...
This Project Grant award of $444,594 from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research into how a major extinction event during the Plio-Pleistocene transition impacted the interactions between flatworm parasites and their clam hosts in the western Atlantic Ocean. The project aims to evaluate changes in parasite prevalence, abundance, body size, and impacts on host growth and longevity, as well as utilize geochemical proxies to understand the...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $317,996 to the University of Texas at Austin to conduct research on the mechanisms of bioturbation and ecosystem engineering by benthic infauna (bottom-dwelling organisms) in marine sediments. The project aims to: 1) Examine the relative contributions of infaunal community structure, sediment mechanical properties, and environmental factors to bioturbation rates; 2) Investigate how...

The National Science Foundation (NSF) awarded a $212,201 Project Grant under the Geosciences program (CFDA 47.050) to the University of Alabama for a collaborative research project titled "Energetic Controls on Marine Benthic Community Structure in Space and Time." The project aims to:

  1. Evaluate how surface productivity affects the energetic and trophic structure of marine benthic communities on both sides of the modern Isthmus of Panama.
  2. Use this knowledge to assess the fossil record of Caribbean benthic ecosystems before, during, and after the uplift of the Isthmus.
  3. Relate ecosystem changes driven by productivity shifts to the well-documented Caribbean extinction event ~2 million years ago.

The project leverages the Panama Paleontology Project's collections of modern mollusks and fossil samples to apply new imaging and automated morphometric technologies. It also explores how trophic composition, larval dispersal, and predatory attack frequencies in mollusk shells vary across productivity gradients in modern and fossil assemblages. The project period is from September 1, 2024 to August 31, 2027.
