Fun with ARISA

We use a technique called ARISA in order to analyze the diversity of yeast in the antarctic soils. This technique can help us analyze how many different species are in the soil without having to culture them. Most Eukaryotes are not culturable, they can't grow on a petri dish in lab conditions, because they rely so heavily on the other organisms they live near that once separated from them they will die. There are many other reasons that most yeast won't grow but in the end it means that we wont know what that community was actually like. ARISA helps us to accurately describe the yeast communities we study.
