This $360,460 federal Project Grant awarded by the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences Program (CFDA 47.050) supports research to understand the relationship between surface productivity and ecological structure in marine benthic communities across the modern Isthmus of Panama. The key objectives are to: (1) evaluate how productivity affects the energetics and trophic structure of marine benthic communities, (2) use this knowledge to assess the fossil record of Caribbean benthic ecosystems before, during, and after the uplift of the Isthmus, and (3) relate ecosystem changes driven by productivity shifts to the documented Caribbean extinction event ~2 million years ago. The project leverages extensive collections from the Panama Paleontology Project and applies new technologies like high-throughput imaging and automated morphometrics to analyze size-frequency distributions and energetic measures. The research aims to advance the scientific community's understanding of how ecological traits like trophic composition, larval dispersal, and predatory attack patterns are influenced by productivity in modern and fossil systems.
