Exploring cyanobacterial diversity in Antarctica Blog

1 Post tagged with the antarctic tag

There are many small ponds and lakes at Cape Evans, similar to Cape Royds . After a quick survey of the ponds, we concentrated on five ponds for sampling. We sampled for morphological, DNA- and RNA-based analysis of the cyanobacterial diversity, as well as nutrient analysis of the water.


In one pond we found a pink coloured layer at the bottom of the mats, which is due to the presence of purple bacteria that  are anoxygenic phototrophs.

I'm Anne Jungblut from the Botany Department. Join me as I head to Antarctica to study cyanobacterial diversity in ice-covered lakes of the Dry Valleys and Ross Island where already scientists on Scott's and Shakleton's expeditions made many discoveries.
