This three-year, $317,027 project grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) will support collaborative research on the phylogenomics and taxonomic revision of the diatom order Rhopalodiales. The research team, consisting of scientists from three U.S. universities and seven international institutions, will gather genomic and morphological data to address the evolutionary origins and diversification of Rhopalodiales. They will seek to determine when the...
This National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) Project Grant, awarded to New York University (NYU) on August 1, 2024, provides $552,466 in funding over a 3-year period to conduct collaborative research on the phylogeny, systematics, and adaptation of marine epizoic diatoms to endangered megafaunal hosts. The key objectives of this project are to: 1) document and describe up to 50 new diatom species living on marine animals like sea turtles, whales, and manatees;...
This $918,053 Project Grant award from the National Science Foundation (NSF) Biological Sciences program (CFDA 47.074) supports fundamental and applied research to document and characterize the diverse communities of marine epizoic diatoms living on endangered marine megafauna. The overall project objectives are to: 1) describe and formally document up to 50 new species of epizoic diatoms; 2) reconstruct the phylogenetic relationships of these diatoms to understand their evolution and...
This $257,498 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) is funding a 3-year research project at The Leland Stanford Junior University to characterize Rhizosolenia diatom mats and their associated nitrogen-fixing microbes in the North Pacific Subtropical Gyre. The project aims to determine if these diatom mats obtain nitrogen from symbiotic diazotrophs, which could transform the understanding of their role in oceanic nitrogen and carbon...
The National Science Foundation awarded a $1,101,964 project grant to the Institute For Systems Biology under the Biological Sciences program (CFDA 47.074) for research titled "COLLABORATIVE RESEARCH: IMAGINE: QUANTIFYING DIATOM RESILIENCE IN AN ACIDIFIED OCEAN." The grant, awarded June 15, 2021 with a completion date of May 31, 2024, will fund research to increase scientific understanding of how diatom populations respond and adapt to increasing ocean acidification. The Biological...
This Project Grant award from the National Science Foundation Division of Integrative Organismal Systems provides $1.6 million to support research under the Biological Sciences program (CFDA 47.074) from August 2021 through July 2024. The grant funds the development of new molecular genetic tools by the J. Craig Venter Institute to define phenotypes in the diatom Pseudo-nitzschia, which can cause harmful algal blooms. Two subawards totaling $100,000 each were provided to the University of...
This National Science Foundation project grant award of $1,053,775 provides funding from June 1, 2023 through May 31, 2026 to support research examining the cellular metabolism and physiology of diatom-diazotroph associations (DDAs) and evaluate their ecosystem and biogeochemical impacts. The University of Rhode Island will investigate the responses of DDAs to different nitrogen sources and temperatures, compare DDA physiology and metabolism to asymbiotic diatoms, and model ecosystem-level...
This three-year, $390,357 National Science Foundation project grant under the Geosciences program (CFDA 47.050) will support research investigating marine diatom-parasite relationships in upwelling systems. The principal investigator at Princeton University will analyze archived samples from diatom-dominated upwelling regions using tag sequencing, metagenomics, and quantitative PCR to identify diatom-parasite pairs and examine their abundance, diversity, and dynamics over the course of blooms....
This $713,951 Project Grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) supports research into the adaptability of phytoplankton carbon dioxide concentrating mechanisms to changing climatic conditions. The grant to Columbia University will fund experiments to quantify the plastic and adaptive responses of carbon fixation in five key phytoplankton groups - diatoms, dinoflagellates, green algae, coccolithophores, and cyanobacteria - under climate change...
This National Science Foundation Project Grant under the Geosciences Program (CFDA 47.050) provides $734,947 in funding to the University of Rhode Island to conduct collaborative research on the life cycle of phytoplankton blooms in coastal ecosystems. The research team will analyze a unique set of samples and data collected in 2021-2022 to better understand the metabolic, functional, and taxonomic interactions between phytoplankton and associated bacteria that influence the timing and...
