The Exciting World of Marine Macroalgae by Melanie Plunk and Amanda Brown

On Tuesday we ventured back to Boiler Bay to conduct individual team studies on a specific species of algae, our assigned "Treasure Taxa". We collected different types of data based on the study that we were performing like algae abundance, size, or preferred habitat. For example, my team (Melanie and Landon) conducted a study to find out which habitat type Farlowia mollis '15 preferred to inhabit. We collected data on the abundance of our species in a variety of different habitats then analyzed the data and made the conclusion that Farlowia mollis prefer to inhabit rocky, concave, seep areas at the base of mussel beds.

We attended lectures that focused on the phyla Chlorophyta (green algae), Ochrophyta (brown algae), and Rhotophyta (red algae), learning about their diversity, morphology, anatomy, and life cycles.
On Wednesday, we were given the morning to finish up our Specimen ID sheets and begin setting up for our team projects, which we presented in the evening. Each team set up their displays at their stations around the lab, incorporating their own creativity into informational displays.

We spent Thursday studying for our lecture final and lab practicum, with a final lecture on ecology and Annette’s master’s work starting off the morning. Miram submitted a manuscript for her research on zooplankton to the Journal of Plankton Research online and allowed us to watch, so as to acquaint us with the process for when the time comes for us to do the same! This was followed by a student-led lab review and a lecture review by Annette. The rest of the day was left open for studying, and students most of a sunny day staring wishfully out of library and lab windows.
Friday morning brought first a lecture final and then a lab practicum. Miram surprised the class with pre-final cinnamon rolls for an extra brain boost, and the morning flew by in a flurry of questions and identifications. Soon it was time to clean up the lab (who knew one class could have used so many Tupperware?) and say goodbye to Annette and Miram, thanking them for a wonderfull class. After a much-needed weekend, we return to HMSC to begin Community Ecology on Monday.
