The research will develop innovative mathematical methods to predict...
This five-year, $785,103 project grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) will develop novel bioinformatic tools and resources for genomic analysis of giant viruses. The Virginia Polytechnic Institute and State University will create computational resources to assess draft metagenome-derived giant viral genomes and integrate them into a taxonomic and phylogenetic framework. Tools to quantify the role of giant viruses in eukaryotic genome evolution...
The National Science Foundation awarded a $207,000 Project Grant to support research titled "Elucidating the Diversity, Prevalence, and Stability of Deep-Sea RNA Viruses" from February 1, 2021 through January 31, 2024. This funding was provided through NSF's Biological Sciences program (CFDA 47.074), which aims to promote progress in the biological sciences and strengthen the nation's scientific enterprise through increasing knowledge and understanding of major problems....
This National Science Foundation (NSF) Project Grant award under the Biological Sciences (CFDA 47.074) program provides $240,000 over 3 years to fund a postdoctoral fellowship focused on understanding how climate change-driven shifts in environmental conditions, such as increasing salinity, affect viral activity and its influence on microbial host genomes and phenotypes. The research aims to explore the large-scale impacts of these changes on microbial evolution and global biogeochemical...
The National Science Foundation (NSF) awarded a $449,462 Project Grant under the Geosciences Program (CFDA 47.050) to the University of South Florida (USF) to study the effects of SUP05 cells and viruses on nitrogen cycling in marine oxygen minimum zones. The project is evaluating how the interactions between SUP05 bacteria and the viruses that infect them impact nitrogen transformations and loss processes in these ocean regions. Through a combination of in situ measurements, DNA/RNA sequencing,...
The National Science Foundation Division of Ocean Sciences awarded a $3 million Project Grant to the Virginia Institute of Marine Science under the Geosciences program (CFDA 47.050) to study biotic and abiotic drivers of pathogen transmission in marine systems influenced by climate change. Specifically, the award will fund research examining how climate change and other human impacts alter disease transmission dynamics in marine populations. The project focuses on investigating the...
This $408,738 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) supports collaborative research to investigate the effects of SUP05 bacterial cells and the viruses that infect them (phages) on nitrogen cycling in marine oxygen minimum zones. The project is led by the University of Washington, and aims to detail the combined impact of SUP05 cells and their associated phages on nitrogen transformation and loss processes in these ocean regions. Through a...
The National Science Foundation (NSF) awarded a $815,899 Project Grant under the Geosciences (CFDA 47.050) program to the University of Miami's Rosenstiel School of Marine and Atmospheric Science (RSMAS) for a project titled "Unraveling the Ecological and Evolutionary Drivers of Marine Giant Virus Community Dynamics".
The project aims to elucidate the ecological and evolutionary determinants of marine nucleocytoplasmic large DNA viruses (NCLDVs), commonly known as "giant viruses", through a comprehensive, year-long time-series analysis at a coastal research site in Quantuck Bay, New York. The research will assess the importance of environmental and intrinsic factors in shaping the diversity, function, and evolution of these giant viruses, which play significant roles in modulating marine biogeochemical processes and microorganism populations. The project will integrate advanced genomic and transcriptomic techniques to uncover the diversity and metabolic capacities of the NCLDVs, evaluate how their ecological strategies map to the composition of marine microbes, and explore their associations with diverse hosts. The award period is from September 1, 2024 to August 31, 2027.
