Along with colleagues from New Zealand, Argentina, and Malaysia I’m convening a session on microbial ecology and evolution at the upcoming biennial SCAR meeting in Kuala Lumpur (because there’s no better place to talk about ice than the tropics). If this sounds like your sort of thing check it out!
The ecology of Antarctica is largely shaped by microbes, with microbial life, including prokaryotes and unicellular eukaryotes, serving as the main drivers of ecosystem function. Given this, it is perhaps surprisingly that our current understanding of Antarctic biota has been derived primarily from studies of metazoans. Despite major advances in the field of Antarctic microbiology in recent years there remains a knowledge gap in our understanding of the distribution, functions, and adaptations of Antarctic microbes. There is a general consensus that Antarctic microorganisms are highly diverse, and in many cases encompass endemic gene pools with unique physiological and genetic adaptations to the extreme conditions of their environment. Relatively recently, the advent of ‘omics platforms has allowed researchers to observe these processes in great detail. This session welcomes submissions on all aspects of microbial ecology and evolution in Antarctica and the Southern Ocean. This includes ‘omics-based approaches to understanding prokaryotic and unicellular eukaryotic diversity, function, adaptation, as well as laboratory and field-based studies of microbial and ecological physiology. Special consideration will be given for abstracts addressing the following issues: (1) Microbial biogeography, functional redundancy, and ecosystem services; (2) Trophic connectivity between prokaryotes and eukaryotes; (3) Cold adaptation strategy and evolution; and (4) Multiple ‘omics integration addressing systems biology of Antarctic ecosystems.
