This summer Chris set up one of the big experiments for his dissertation. He is interested in studying the influence of the microbial community on biogeochemical cycling in the bottom of a hippo pool, and the interacting effects of carbon loading and microbial community structure on those effects. He came up with a really clever way to test this by developing small "hippo pools" in 1 liter bottles, which allowed him to have lots of replication across different treatments. In total, he set up around 150 bottles!

We sampled the bottles for about 12 different parameters at various time points over a few weeks. We could see some of the results immediately in the field as we collected the data, and it was really exciting to watch the changes in the different treatments over time. A lot of additional data will be analyzed from this experiment back in the lab at Yale.

It was a ton of work, but the preliminary results are really interesting. We saw some of the changes we expected to see, and others that were a complete surprise. Unexpected results are often the most exciting in science because they suggest new hypotheses and mechanisms you may not have considered already. We also had a great team, which makes all the difference. Everyone had a job, James played DJ on his ipod, and we had a lot of fun!
