"Understanding Population Genetic and Genomic Patterns of Marine and Aquatic Communities over Time and Space"

Metagenomics here is defined as the simultaneous study of the genetic code, population genetics, and genomic adaptations of entire communities (multiple taxa, ranging from all microbes, viruses, plants, animals, etc.) recovered directly from a variety of samples (e.g., environmental samples, parts of organisms, and/or entire organisms). Environmental samples include those from water (containing shed mucus, waste, cells), sediments, sediment cores (dating back thousands of years), plankton, eggs, larvae, gut contents, parts of organisms, and/or entire organisms. Metagenonomic and High-Throughput (a.k.a. Next-Generation) Sequencing approaches and technology today allow researchers to accurately identify all operational taxonomic units (OTUs) to species and population levels, and in the near future, will be broadly applied across all oceanic OTUs. The broad applications now will allow us to simultaneously monitor and collect data to understand the adaptations and patterns of entire ecosystems, cross-linking biological oceanography (systematic biology, taxonomy, population genetics, genomics, morphology, biogeography, ecology, physiology, etc.) with physical oceanography (acidification, temperatures, chemical parameters, current patterns, greenhouse gases, geology, historic geography, climate change, etc.). Through this seminar presentation, we explore examples from marine and aquatic ecosystems, and their application to research on entire communities, including those in the deep sea, sediment cores dating back thousands of years, as well as plankton, gut contents, and pathogens. The limitations today posed by the paucity of morphological data and correct OTU identities, museum samples, and accuracy of Genetic databases, including GenBank and the Barcode of Life will be discussed, as well as the potential future of these and other evolving genomic approaches. These types of metagenomic approaches and bioinformatic technology, which are evolving every day, will transform scientific understanding of our oceans and their patterns across time and space in the face of climate and anthropogenic changes throughout the next two decades.
