Life Without Oxygen and Other Tales of Tiny Organisms with Big Impact
Distributions and activities of all marine organisms are shaped by oxygen availability. Expansion and intensification of already large oxygen-stressed areas of the coastal and open ocean are predicted in response to ongoing human activities and climate change. Ocean deoxygenation has significant ecological consequences, including habitat loss, modification of the marine food web, and production of trace gases that have pronounced feedbacks on climate, such as methane and nitrous oxide. These oxygen-depleted marine habitats are systems of intense chemical cycling by microorganisms. However, our ability to fully comprehend consequences for marine ecosystem is hampered by our limited knowledge of the in-situ rates of key microbiological processes and the dynamics of the microorganisms mediating them. In @microbiaki lab, we use a combination of approaches including molecular techniques, bioinformatics, biogeochemical measurements and microscopy to address questions on the identity, biogeography, ecophysiology and interactions of marine oceanic microorganisms. I will discuss my lab's past and on-going efforts to decipher the microbial functions and activities at the community and single-cell scales, in oxygen-depleted and other marine systems, as well as our effort to develop samplers to reduce methodological biases.
