Bacterioplankton (including Bacteria and Archaea) drive oceanic biogeochemical cycles, regulating the composition of Earth’s atmosphere and influencing climate. Thus, any factor affecting bacterioplankton activity and/or community composition might have strong implications in the functioning of the marine environments and its ecosystem services. Despite the recognized importance of bacterioplankton in the marine environment, the factors controlling their distribution, activity and diversity remain elusive. In this presentation we will begin talking about ‘classical’ bottom-up and top-down factors affecting heterotrophic bacterioplankton populations, followed by some other novel factors that might be important drivers of present and future bacterioplankton communities.
About the author:
Federico Baltar is a lecturer at the Department of Marine Science at University of Otago (NZ). His research in microbial oceanography integrates marine microbial ecology and biogeochemistry. His research group mainly focuses on the role of microbes on the marine biogeochemical cycles by looking at the factors that control their diversity and function, trying to follow a multidisciplinary approach with the aim to draw connections between different scientific disciplines. He has received different research-related awards, including the European Geosciences Union (EGU) Award for Outstanding Young Scientist in Biogeosciences (2016).
