Antarctica – what it takes to get down and back out of the rabbit hole
Three Antarctic expeditions spanning 10 years, sampling through winter for a total of 18 months, and 3 dedicated years of bioinformatics analysis – we’ve finally learned the well kept secrets of Antarctica’s, Ace Lake microbes.
The paper in Microbiome is here: Influence of the polar light cycle on seasonal dynamics of an Antarctic lake microbial community
To start with, this is what we do and why:
Rick Cavicchioli’s group studies Antarctic microorganisms, discovering which types live in and around Antarctica, learning how they evolve and grow in the cold, and assessing how they are likely to respond to ecosystem changes, including climate change.
The research is important because environmental microbes enable all other life forms on Earth to exist, and the vast majority of life on the planet grows at low temperatures.
And where exactly do we do the work? Ace Lake, Vestfold Hills, East Antarctica – take a look:
Then, after several years for DNA extractions by Tim Williams and sequencing by JGI, Pratibha Panwar performed three solid years of analysis as the core of her PhD studies.
And the outcome.
Then the article.
