Microbial Ecology and Evolution in the Deep Sea and Beyond


The genomic revolution has opened many exciting avenues of research in the study of biodiversity, none more so than the study of the largest reservoir of genetic and metabolic diversity, the microbial biosphere. Microbial metagenomics and metatranscriptomics are beginning to provide detailed information on microbial taxon diversity, population dynamics and metabolic diversity in a variety of habitats ranging from marine systems to the human microbiome and are helping us to understand complex processes such as biogeochemical cycling in the oceans, host-symbiont interactions, and microbially mediated human disease. I will discuss a range of topics related to host-microbe ecology and evolution. These topics include intracellular symbiont population genetics and evolution in two deep-sea bivalve taxa, one predominately vertically transmitted and the other horizontally acquired. I will also describe the diversity of microbialcommunities in the cystic fibrosis lung uncovered by 454 amplicon sequencing. Finally, I will discuss metagenomic and metatranscriptomic studies conducted on free-living marine microbial communities. Together, these studies highlight the immense promise that emerging technologies hold for the study of microbial ecology and evolution.
