+    "In this study, there were 88 soil samples collected from North and South America.  Each of these soil samples had a pH measurement. From this [paper](http://www.ncbi.nlm.nih.gov/pubmed/19502440), it was determined that pH is a major driving factor for the microbial communities.  Here, we will show that pH by itself can actually predict the microbial abundances, using balance trees."
