UNSW Science<\/a> Professor Rick Cavicchioli is an expert in microbes and why they are so important\u2014just last year, he led an urgent call for the world to stop ignoring this “unseen majority” in Earth’s biodiversity and ecosystem when addressing climate change.<\/p>\n

\n <\/section>\n

In their widely covered and discussed scientists’ warning, Prof Cavicchioli and researchers around the world raised awareness both for how microbes can influence climate change and how they will be impacted by it\u2014calling for including microbes in climate change research, increasing the use of research involving innovative technologies, and improving education in classrooms.<\/p>\n

Now, Prof Cavicchioli has published another important piece on microbes\u2014this time, a research paper that has been more than a decade in the making: after three Antarctic missions, including one that ran for 18 months, plus three years of bioinformatics analysis, the scientists can now reveal the secrets of Ace Lake’s microbes.
\nIn the paper, Prof Cavicchioli and team show how these microbes have adapted to the polar light cycle. The researchers found that two types of microbes\u2014green sulfur bacteria (GSB) and cyanobacteria\u2014were most abundant in the lake, and that they were highly influenced by light availability. The GSB decreased in numbers in winter and bounced back to higher levels in spring.
\nThe researchers believe that the GSB in the lake have evolved specifically to life in Antarctica. Because they are specialized, the research team predicts that the same GSB will be found in other Antarctic aquatic systems, and they are currently doing research now to find out if it is true. One thing that concerns the scientists is the threat from introduced (invasive) viruses that could destroy the GSB, thereby perturbing the whole lake ecosystem.<\/p>\n
