It is finally summer time! The sun is out, the weather is warm- and that means it is time to study some algae. Thank you all for supporting me and this project, and I hope to reward your support by providing these updates for the experiments. As with nearly all experiments, the design has changed slightly in the time since this project was first proposed. The goal of understanding the role of iron in the growth of blue green algae remains the same, but hopefully now I will be able to get a more accurate answer to that question. The main change is the addition of using sediment cores to better understand natural release rates of elements from the sediment. I will get into more detail about these changes in following posts, so until then, enjoy the scenery of Grand Lake!

About This Project

Blue green algae (BGA) blooms are becoming alarmingly frequent and conspicuous across the world, posing significant economic and health risks. The ability to fix atmospheric nitrogen (N) is a key trait conferring a competitive advantage to BGAs. N fixation is orchestrated by the enzyme nitrogenase, which is 59% iron (Fe) by mass. However little is known about the role of Fe in BGA growth. We will explore the role of Fe in determining BGA growth using experimental manipulations of Fe supply.
