Title: Biosensors of Environmental Change: Linking the Global Marine Microbiome with Ocean Processes
Presenter: Dr. Alyse Larkin
Abstract: Microbes are the drivers of most major bioenergetic transformations in the ocean. Moreover, the high diversity and fast division rates of microbes allow them to function as excellent "eco-genomic biosensors." Rapid adaptation driven by environmental selection results in cladogenesis and new bacterial taxa. Thus, we are able to let the genomic information present in diverse microbial lineages tell us about the multidimensional stressors that they experience. In this seminar, I will discuss how microbial genomes reveal cellular processes and shifting environmental stressors, including global ocean chemistry on GO-SHIP cruise transects and regional El Niño-driven temperature change.
